The connections within are called branch circuits and usually represent the end of a conduit run. Junction boxes make wire access easy, since all one must do is remove the covering to make alterations, repairs, or additions to a conduit. Junction boxes also protect wiring from the elements or environment, which can sometimes be corrosive or otherwise harmful to wiring material. Finally, junction boxes protect wiring from unwanted tampering, whether malicious or unintentional.

Junction Box Wiring Basics
Essentially, a junction box houses wire connections in order to split off power from a single source to multiple outlets. For instance, a junction box might contain one wire power source that is connected through multiple wires to power several different lights.

Electrical junction boxes are usually between 2 ½ to 3 ½ inches long and made of metal or hard plastic. The functional difference between plastic and metal depends whether or not the junction box is supposed to support any weight. Some metal junction boxes can support light fixtures; plastic junction boxes cannot withstand this weight. Additional differences include installation, in that plastic IP65 junction boxes are typically quicker and easier to install than metal ones. However, a standard junction box designed to simple cover wire splices can be either metal or plastic.

Wire Splices in Junction Boxes
All wire splices must be contained within a junction box for a building to meet electric code, although sometimes splices are missed and may present hazards as a result. Any exposed wiring can be dangerous, but exposed wire splices are especially prone to accident because they can be tripped over, expel sparks or misrepresent themselves be misperceived as playthings by children or pets. Junction boxes are helpful for wire splices because they also allow one to easily locate the wire splice area.

Waterproof junction boxes provide an important function of providing a safe transition of power produced from the photovoltaic (PV) cells in the laminate to the external wiring system for interconnecting modules and loads. Electric distribution boxes, also referred to as “jboxes,” are used in a wide variety of electrical applications and serve to protect the connections between wires and cables. In a PV module, however, the jbox also houses the bypass diode that provides a PV cell-protective function and it is prewired and terminated for rapid interconnection of modules in the field. The junction box enclosure consists of a body enclosure and lid both of which are almost exclusively made of injection-molded polymeric construction and are adhered to the substrate of the module with an adhesive compatible with both the junction box polymer and PV module substrate.

The combination of the enclosure, bypass diode, transitioning wiring, connectors, and adhesive makes the jbox a complex component that appears deceptively simple and is not designed to be maintained or serviced. This combination of system behavior and lack of maintainability poses a reliability challenge for the PV module manufacturer, where a service lifetime of 25-years is expected. The importance of design, characterization of the failure and degradation modes, sufficient qualification and durability testing, and manufacturing quality control for the Jbox system (box and connectors) cannot be overestimated since failures of this system account for approximately 18% of 180 fire incidents studied from 1995 to 2012. This study indicates that the jbox with its associated PV connector was the number one cause for a fire, with the second being inverters at 16%. The International Energy Agency’s 2014 report suggests that PV connectors alone may be responsible for up to one-third of PV module fire incidents suggesting that special attention to this component is required.

A junction box is an electrical enclosure that protects electrical conductors at the points where they are spliced, tapped and pulled. These enclosures allow electricians to easily access the conductors to perform work when needed while simultaneously keeping the conductors safe from damage and unauthorized access.

Sometimes, you’ll hear the term “junction box” used to refer to an electrical fixture box. In the true technical definition of a distribution box, wires should connect only to other wires and raceways. However, in practice, the term is also frequently used to refer to many other electrical box types in which wires connect to a fixture such as a ceiling fan, light switch or wall socket.

Sizing a junction box is critical for making sure the junction box functions correctly. In a junction box that’s too small, an electrician may have to bend conductors excessively to fit them fully inside the box, which risks damaging the insulation on the wires. Conductors and other components spaced too closely may also create interference or hazardous conditions.

Article 314 of the National Electrical Code contains most of the key regulations that you’ll need to follow when choosing and installing a junction box. These regulations describe in detail the required junction box size, depending on the number and size of conductors and fittings enclosed within the box.

You’ll need to calculate both box volume and box fill when determining the appropriate size for a power distribution box. What do these concepts mean?

Box volume is the total enclosed volume of the junction box, including any extended space provided by attachments such as domed covers or extension rings.
Box fill is the total space occupied by the components that will be contained within the junction box with electric breaker.
The box volume should always be greater than or equal to the box fill. To calculate box volume and box fill, you’ll need the tables from NEC 314.16 and knowledge of how to use them. Next, we’ll look at how to use these important tools.]]> Junction boxes are metal or plastic enclosures used as housings for wiring connections.

Sometimes it uses a four-wheel-drive tractor, but usually a track or crawler type, mounted on continuous metal treads, is employed. The blade may be lifted and forced down by hydraulic rams. For digging, the blade is held below surface level; for transporting, it is held at the surface level; and for spreading, it is held above the surface level, as the tractor moves forward.

Bulldozers are used for shallow digging and ditching; short-range transportation of material; spreading soil dumped from trucks; rough grading; removing trees, stumps, and boulders; and cleaning and leveling around loading equipment. A bulldozer alone can do many types of excavation, and it is useful in combination with other machinery in most excavation work.

Our company have different types of bulldozers, the most typical ones are Shantui Bulldozer and XCMG Bulldozer.

Most people don't realize this, but a bulldozer is actually classified first and foremost as a tractor! The difference between a dozer and a farm tractor comes from the metal plate (also called a blade) featured in the front of the bulldozer. Similar to a tractor, however, the bulldozer is used to push massive amounts of debris and raw material, including sand, rocks, dirt, and bricks.

Bulldozers work primarily thanks to the force exerted by their tracking system. The tracks that rotate around the bottom of the dozer, like a circulating belt, are responsible for its considerable resilience on tough terrain and its ability to transport and retain hefty loads.

Other significant parts of the bulldozer are the ripper and the blade. As mentioned, the blade is often used interchangeably with “plate” to refer to the large metal structure on the front of the dozer. This is the part responsible for doing the heavy pushing.

The ripper of the bulldozer is found on the opposite side from the blade, all the way in the back of the machine. As the name suggests, this device "rips" up the ground and material covered by the bulldozer. It is shaped like a claw to produce this powerful shearing effect. If the ground is tightly packed together or compacted, the ripper will render the soil into a softer, more workable state.

The effective work woth bulldozer also rely on the suitable and well-made Shantui Spare Parts including Shantui SD16 Spare Parts, Shantui SD22 Spare Parts, Shantui SD32 Spare Parts and Shantui SD23 Spare Parts. ]]> Bulldozer, also called Dozer, powerful machine for pushing earth or rocks, used in road building, farming, construction, and wrecking; it consists of a heavy, broad steel blade or plate mounted on the front of a tractor.

The earliest pumps were devices for raising water, such as the Persian and Roman waterwheels and the more sophisticated Archimedes screw (q.v.).

The mining operations of the Middle Ages led to development of the suction (piston) pump, many types of which are described by Georgius Agricola in De re metallica (1556). A suction pump works by atmospheric pressure; when the piston is raised, creating a partial vacuum, atmospheric pressure outside forces water into the cylinder, whence it is permitted to escape by an outlet valve. Atmospheric pressure alone can force water to a maximum height of about 34 feet (10 metres), so the force pump was developed to drain deeper mines. In the force pump the downward stroke of the piston forces water out through a side valve to a height that depends simply on the force applied to the piston.

We mainly use the pump for cosmetic application. for example, we have Custom Foam Pump, Cosmetic Treatment Pumps, Crimp Pump and Makeup and Nail Remover Pump. Except for the pumps, we also have different cosmetic products like bottles and sprayer.

Cosmetic bottles are perfect for skin care and beauty products. They can contain gels, creams, lotions and deep skin cleansing products. Most jar containers come with a shive (a flat plastic shelf that fits inside the jar) used to keep the contents free from foreign debris (dust & germs). Moreover, jars are designed with airtight lids, which keep the contents fresh and ready for future use. The most commomly used are Cosmetic Airless Bottle, Cosmetic Lotion Bottles, Multi-purpose Plastic Bottle and Foam Bottle.

As for the sprayer, there are also many kinds like Plastic Hand Trigger Sprayer, Plastic Fine Mist Sprayer, Perfume Mini Sprayer and Perfume Credit Card Sprayer. cosmetic industry developed prediction models for the best estimate of inhalation exposure combining data from computer simulation programs available in the market, individual real measured data and last but not least the experience from the market.

A leotard is a unisex skin-tight one-piece garment that covers the torso from the crotch to the shoulder. Leotards are entered by stepping into the legs and pulling the sleeves over the shoulders. Scoop-necked leotards have wide neck openings and are held in place by the elasticity of the garment. Others are crew necked or polo necked and close at the back of the neck with a zipper or snaps.

It only make sense that an article of clothing that clings to the body and leaves little the imagination would have an etiquette with it. Knowing when it is and is not okay to wear a Ballet Dress can mean a lot when it comes to your social standing and self-worth. Wear it at the wrong time and you can be ostracized, but wear it at the right time and you will be hailed as a fashion guru. So how do you know when it is okay to wear an Adult Ballet Leotard? There are some simple rules you can follow.

First in Ballet Dresses for Girl etiquette is that you can wear a leotard if you are appearing on stage. If you are dancing, in a ballet, part of an opera, or doing performance art, you can wear a leotard and you will be fine. If you are a rock star, you can wear a Ballet Pants in only a couple of situations: if you are a woman or if you are an 80s hair band lead man (see Poison, Twisted Sister, or Abba). A basic rule of thumb, though, is that if you are on stage performing, you can get away with a Dance Studio Pants.

And it is also a indispensable stuff for Yoga Wear. It is very normal to wear a Yoga Tops for Women and Yoga Pant for Women when you are having a yoga class with your besite.

Thirdly, leotards are okay if you are a super hero or playing one for Halloween. Superman, Batman, and many other comic book superheroes made the Compression Tights okay. Its sleek tight fit make for a great outfit when fighting crime. No extra fabric to get snagged and nothing to resist wind as you fly or run at the speed of light. If you are going the super hero route, however; you must make sure you wear proper boots and cape to complete the ensemble. Also, superhero leotards should always be worn with bikini briefs over the top. Heroes are modest.

When it comes to leotard etiquette, you have to ask yourself if you should be wearing one. As a piece of clothing that stands out and leaves little to the imagination, you should think long and hard about what you are putting on if the option of a leotard comes up. If you are performing dance, performance art, or hair band music then you are probably okay. Also, if you are a super hero or just trying to play one for a costume party or Halloween, again, you should be okay wearing a leotard. If, though, you are more than a little overweight or not confidence in what you are displaying, a leotard is not okay. A good rule of thumb for leotard etiquette is when in doubt, wear something else or something over it.]]> When to Wear a Leotard?

Disposable coverall is an item of personal protective equipment (PPE) designed to cover the whole body and other clothing to protect against dirt or other outside contaminants. Coveralls are one piece and loose fitting for ease of movement, with sleeves, full leggings and often a hood to cover the head. These can also include overshoe pieces to cover footwear and protect against contamination.

Safeopedia Explains Disposable Coveralls
The purpose of using disposable materials to make coveralls is to avoid cost issues when using non-disposable materials which are certain to sustain damage when used situations that require coveralls very regularly, for harsh work conditions. Common materials used to make disposable gear are Tyvek, Polypropylene or Tychem. These materials have different safety ratings and properties which suit them to different environments. For example; some suits can be used in hazardous situations to protect from acid spills or hazard chemicals while some more breathable varieties may not. The American National Standards Institute (ANSI) and The Occupational Safety and Health Administration (OSHA) have provided regulations and standards for the design, testing and use of disposable coveralls which should be considered by employers while making a risk assessment, safety plan and choosing PPE.

Choosing the Right Disposable Coveralls
Specifically, it looks closely at disposable coveralls such as the kind used for protecting against chemical sprays or hazardous dusts like asbestos.
Why use protective clothing such as coveralls?
Workers can be exposed to many hazardous chemicals, mists and particles in the workplace. For example, asbestos is a well-known hazard, causing serious health issues such as mesothelioma and cancer. The smallest amount of inhaled asbestos can cause health problems, hence the stringent regulations and standards for handling asbestos in Australia.
In addition, many other harmful dusts and chemicals can be encountered on the work site. Many workplaces and workplace health and safety guidelines mandate that PPE including disposable protective coveralls be used for certain work processes.
In addition to handling asbestos, hazardous processes include working with chemicals, paint spraying, wood work, chemical manufacturing, environmental remediation, cleaning and fibreglass handling.
General guidelines for protective clothing
AS/NZS4501.2 covers general performance requirements for ergonomics, size and marking of protective clothing. It covers the information that manufacturers should supply, and specifies that protective clothing should not cause irritation or harm.
It’s important to note that if coveralls are not a single use disposable item, they must be properly decontaminated. This will help prevent particles or chemicals cross contaminating work processes, environments, and the worker’s regular work clothing.
Tests and standards for dusts, chemicals and particles
Protective coveralls are generally specified with a ‘Type’, which refers to a host of International Standards. These standards cover a wide range of individual performance tests that check for resistance against:

Abrasion and cracking
Tensile strength and tear resistance
Resistance to punctures
Resistance to chemical permeation
Liquid repellence
Resistance to spray and aerosols
Resistance to ignition

Once the garment has passed a series of tests, it is classified into a type depending on its suitability for different applications.
Types of disposable coveralls

Type 1 – Gas tight EN 943-1, EN943-2
Type 2 - Non-Gas tight Garments EN 943-1
Type 3 – Liquid tight EN14605, EN ISO17491-3
Type 4 – Spray tight (saturation) EN 14605, EN ISO17491-4
Type 5 – Protects against airborne particles EN ISO13982-1
Type 6 – Protects against liquid chemicals (light spray) EN13034, EN ISO17491-4

Abrasion and cracking
Tensile strength and tear resistance
Resistance to punctures

Type 5 – Protects against airborne particles EN ISO13982-1
Type 6 – Protects against liquid chemicals (light spray) EN13034, EN ISO17491-4

Garments can also be classified as protecting against a range of hazards – for example, our Microchem 300 chemical splash suit is a Type 3, 4 and 5 coverall.
Type 1 refers to completely enclosed protective suits designed to protect against chemical contamination in the form of liquid or gas. Likewise, non-gas tight suits which retain positive pressure to prevent ingress of dusts, liquids & vapours are referred to as Type 2.
However, the most common classifications of protective coveralls in our industry are 3 through to 6 so let’s look at these in more detail.
Type 3 – Liquid tight
Type 3 coveralls have sealed seams rather than stitched. They must be made from a fabric that is liquid tight and can withstand strong directional jets of a liquid chemical during the test. Only a tiny fraction of liquid is allowed to enter the garment before it is deemed a ‘fail’. This is based on the breakthrough time of a strong jet of liquid at high pressure. The coverall can then be given a class, which relates to this breakthrough time: Class 1 is at the lower end of the scale with breakthrough taking just 10 minutes, whereas Class 6 resists ingress for over 6 hours.
Type 4 – Spray tight
Spray tight protective clothing is generally a coverall that protects against saturation of liquid chemicals. Both the fabric and the seams are rigorously tested where volume of the liquid builds up on the suit, causing pools and rivulets. Testing to meet Type 4 classification is similar to the above chemical test, but a lighter spray at a lower pressure – like a shower.
Type 5 – Protects against airborne particles
These garments are full-body protective items covering the trunk, arms and legs, such as one-piece coveralls or two-piece suits, which can be with or without hoods, visors and foot covers. These are tested to rate their resistance to dust and particles. They are suitable for processes such as light industrial cleaning, site preparation and handling insulation.
Type 5 rated coveralls are also suitable for asbestos work, provided they are disposable rather than reusable.
Coveralls that pass the test as Type 5 are subjected to a test subject performing a series of movements in the suit whilst it is exposed to a dry aerosol with a particle size of 0.6 μm. The inward leakage of the aerosol must be below a minimal threshold.
Type 6 - Light spray protection
This type covers suits that are for protection against light spray and splashes. It differs from the type 3 and 4 spray tests in that there is less volume of liquid sprayed, and no build-up of liquid on the suit. It is the lowest level of chemical protection and is intended to be used if risks have been assessed as low and a full liquid permeation barrier is not necessary.
Types of fabrics
Often protective coveralls like PP disposable coverall are made from materials such as polypropylene, or trademarked fabrics such as Tyvek. They are often grouped under terms that refer to the way the fabric is constructed such as SMS or MPF.
SMS
SMS stands for spun bound / melt blown / spun bound fabric. This process uses a melt blown polypropylene layer sandwiched between two polypropylene layers. This results in a fabric that I strong and durable with strong barrier properties. SMS disposable coverall is generally breathable with some air permeability.
MPF
MPF is a microporous fabric made from a thin microporous film bonded to a spun bound polypropylene base. MPF fabrics are not as breathable due to their very low air permeability. Microporous disposable coverall isalso made of MPF.
Choosing the right coveralls
There are so many variables in any individual application that it is difficult to be specific about what is best. Hence all protective clothing recommendations come with a disclaimer stating that it is the user’s final responsibility to ensure the garment is suitable for the application.
Every selection should begin with a risk analysis to determine the type of risk, the length of exposure and level of protection required. In general, key features to look for include:
Is the level of protection suitable for the task?
How robust or heavy duty are the coveralls?
What is the quality like, including details such as the zipper, seams, fabric?
What is the fit and comfort like? Will the size range be suitable for your workers?
Are the coveralls single use? What should responsible disposal look like?
Are they easy to put on and take off?
Benefits of disposable lab coats
Preventing chemical mixtures and limiting flammability
When a scientist wears a lab coat, spills and contamination of that coat are a fact of life. This means that, if a scientist is wearing the same lab coat every day, all day for a week, the chances that different chemicals with potentially adverse reactions combining on the coat become much higher. Even if a scientist wears the same lab coat all day, and cleans it each day, that risk is still there. When a new coat is worn every time the lab is entered, the odds of a chemical reaction due to what’s on the coat are next to zero. This seriously reduces risks of fire as well as physical risks to the scientist.
Preventing the spread of contagions
Throwing away a lab coat after every work session helps ensure that no diseases leave the lab or examination room. Lab coats must be cleaned, and often off-site. However, bringing an infected lab coat to a cleaning facility could start the spread of a new contagion. Even if the cleaning facility is on-site, that means more hands will need to touch the lab coat to clean or sterilize it between uses. This increases the risk of contagions on the coat spreading elsewhere.
Preventing cross-contamination
Detergent, cleaner, and even cloth fibers from reusable lab coats can get into lab materials. If this happens, it can render a work session meaningless, or even worse, become a danger. Using a single-use lab coat ensures sterility every time that the lab is entered.
Easier to clean
Fabric lab coats need to be bleached to ensure that all contagions are killed. They also need to be thoroughly washed to ensure no contaminants are left after use. Disposable lab coat is usually made from plastic materials which are less porous than cloth fiber. They are easier to wipe down between uses, and can be washed easily with alcohol or bleach wipes to remove pathogens.]]> <![CDATA[What is an LED Downlight?]]> https://uhm.vn/forum/Thread-What-is-an-LED-Downlight--370974 Wed, 10 Nov 2021 14:27:51 +0700 pd11ing10]]> https://uhm.vn/forum/Thread-What-is-an-LED-Downlight--370974 What is an LED Downlight?
An LED downlight can be a completely integrated unit, or it can come in two parts. Ultimately, it's a low energy LED light source fitted inside a downlight housing.
Are LED Downlights as Reliable and Long Lasting as They Say?
Throughout our history, we’ve maintained our relationships with premium branded lighting manufacturers such as Aurora, Collingwood, JCC and Philips Lighting. Even these top-quality brands have had problematic versions of downlights.
The most consistent and reliable downlight of all-time is the Halers H2 Pro. This product was a game-changer for integrated LED technology. We’ve experienced the fewest failure rates with this product, its successfully outlasted its 7-year guarantee period and still remains a market leading product.
The least reliable downlights we’ve sold have been the Aurora I9 and possibly the JCC FGLED6. These particular downlights had a few ‘bad batches’ and unusually high failure rates. However, these brands have learned from their mistakes and gone on to develop more reliable products with the Aurora MPRO and JCC V50.
The truth about integrated LED downlights is that some models come and go quite quickly. This can be a problem if you get a failure and need to replace it. If your particular product has been discontinued then the latest version won't fully match the others.
On occasion, integrated downlights do fail and do need replacing but they are more reliable than the traditional GU10 LED and fire can combination which is the housing of the downlight structure shown in the image above.
If you buy downlights that don't have a wiring cable connector block you'll also have to disconnect them by rewiring them which will mean getting an electrician involved. If you've got downlights with proper plug-in wiring connectors shown below, you can easily disconnect them. Then you can usually reconnect the new one as it should have the same plug-in connector.
These connectors make integrated LED downlights work in a similar way to GU10. Instead of removing the lamp from the fitting, you're removing the fitting from the ceiling. No additional tools required!
What are the Best LED Downlights?
Integrated LED downlights with wiring connectors are considerably better. Collingwood and Aurora downlights are particularly good quality with an especially low failure rate. Integrated downlights have a more modern appearance and feature vastly advanced technology.
If you put a GU10 LED inside a traditional fire can downlight housing and have it on for long periods per day (3 hours+), you'll most likely discover they don't last for very many years and you'll be forever having to replace the LED. Overheating is the #1 cause of LED failure. If you're going to go for GU10, then choose a downlight with airflow like the Aurora EFD Pro, Ansell Edge or Integral EvoFire.
Integrated downlights feature advanced cooling capabilities. They have a dedicated heat sink that dissipates the heat more effectively, which helps to prevent heat from building up like it does inside a fire can.
Benefits of LED recessed lights
Recessed LED downlight produces less heat, use less energy and are more effective at guiding light to its intended destination than other traditional lighting technologies such as incandescent. Since LEDs have a longer lifespan, you’ll save on maintenance costs over time.
LEDs are also available in a wider variety of colors and shades, whereas incandescent bulbs only come in a yellow, warm hue. Popular LED bulbs for downlights in homes usually come in bright, soft or warm whites, but if you want to get creative, you can install smart bulbs that change colors.
Outdoor downlights
Recessed lights are also perfect for outdoor settings. Outdoor downlights can enhance the visual appearance of your home while also boosting security. If you want to add light around the perimeter of a home, you may want to consider installing LED downlights in eaves or overhangs.
What about harsh winter weather? LEDs actually work best in cold temperatures. And as long as you don’t leave them burning all day in the summer, your LED downlights will work just fine outside.
The long-life benefits of LEDs can be especially helpful if you have second-story eaves that are hard to reach. Bulb replacements will be few and far between.
Install recessed lights in your home
Homeowners who want lighting flexibility and in-ceiling fixtures can benefit from installing downlighting.
Combined with energy-saving LED bulbs, downlights can be another way to use modern and efficient lighting throughout an entire home.

An LED downlight can be a completely integrated unit, or it can come in two parts. Ultimately, it's a low energy LED light source fitted inside a downlight housing.
Are LED Downlights as Reliable and Long Lasting as They Say?
Throughout our history, we’ve maintained our relationships with premium branded lighting manufacturers such as Aurora, Collingwood, JCC and Philips Lighting. Even these top-quality brands have had problematic versions of downlights.
The most consistent and reliable downlight of all-time is the Halers H2 Pro. This product was a game-changer for integrated LED technology. We’ve experienced the fewest failure rates with this product, its successfully outlasted its 7-year guarantee period and still remains a market leading product.
The least reliable downlights we’ve sold have been the Aurora I9 and possibly the JCC FGLED6. These particular downlights had a few ‘bad batches’ and unusually high failure rates.

Even people who adore cats have to admit they’re sometimes not the easiest pets to take care of. They have a habit of reminding you it’s time to eat at 5:30 a.m., sometimes by dragging their claws across your eyelids. They leave you presents in the form of other dead animals, sometimes in your bed. And if they don’t like their litter, they will definitely let you know, sometimes by peeing all over your home.
Okay, so cats are strange. But what’s up with the litter? Isn’t it all basically the same? It’s sand that they go to the bathroom in, right?
Wrong. Cats are particular about litter the way humans are about the bathrooms we use. Sometimes the environment is so off-putting to a cat, they’d rather go anywhere else, like in your plants. More seriously, some litters pose health concerns for cats and humans alike, so it’s important to choose the right one. Let’s take a look at why litter matters to your cat, and why it should matter to you.
Litter Matters Because of Texture
A big issue for cats is the texture of the litter. If a cat litter is too rough or the granules are too big, a cat will reject it because it doesn’t feel good under their paws. Remember, they love to dig around in their litter before and after they go, and if the litter is too harsh, they’ll reject it in favor of something else… like your favorite blanket.
Litter Matters Because of Smell
If you’ve ever walked into a bathroom and made a swift exit because of the smell, your cat can relate. A cat will avoid the litter box if it’s too full of waste, so make sure that it’s cleaned every day, especially if you have multiple cats. Alternatively, cats will reject the box if the litter is perfumed too heavily. It’s a delicate balance!
Litter Matters Because of Dust
Dust from clay litter is a big issue for cats and humans alike because both species can suffer from asthma. If you know your cat suffers from asthma, definitely stop using dusty cat litter as it can exacerbate the issue. It can also cause asthma, not just make it worse. Similarly, if you or anyone in your home suffers from asthma, COPD, allergies or other respiratory problems, avoid clay litter and use something else.
Litter Matters Because Cats Are Cats
Okay, so you’ve gone out and bought a soft, non-offensive-smelling dust-free litter and your cat still is using your laundry as his or her litter box. What gives? Sometimes there’s no telling with these stoic creatures, so we say try a cat litter attractant. For whatever reason, this magic dust compels your feline to go in the box. Try it and see what a difference it makes.
Even the most tuned-in cat lovers will despair when their cat refuses to use the box. If you’ve changed litters multiple times and eliminated any behavioral issues, talk to your vet. Your cat might not be feeling well and they are trying to get your attention.

How to Use Crystal Cat Litter?
There are pros and cons of crystal cat litter. Focusing on pros, crystal cat litter is light weighted, low in tracking, and good for the hygiene of your cat.
It is easy to use, has an effective moisture lock technique, and is dust-free. The con is it is not environmentally friendly, can cause health issues to humans and animals if disposed of in the soil.

It is your choice either use it or not! We have described all steps on how to use crystal cat litter in this article. You can read it and apply.
1. Keep the Litter Box in a Private Place
Cat’s demand privacy when they eliminate. So, if you don’t know how to use crystal cat litter, the first step is to put her litter box in a private space where she can calmly defecate in peace.
Cats want security; it is their natural instinct that comes from their ancestors. When you place a litter box, make sure it is placed in a calm and low-traffic area. They should not feel vulnerable while doing their toilet business.
2. Ensure the Quantity
It is best recommended to fill the cat litter box between one and a half to two inches. This will prevent urine from reaching the bottom of the box.
You can get Fresh Step brands Premium Crystals Cat Litter product to your house. It has odor control properties that keep it five times fresh. The crystal locks the urine quickly.
Is your cat fond of digging in the litter box? In that case, you should put extra litter in her box around 2 inches so that it locks the liquid and prevent it from reaching the bottom of the floor.
3. Slowly Introduce to Silica Gel Crystals Cat Litter
Cats don’t appreciate sudden change. They take time to accept different litter types. So, when you plan to use Silica Gel Crystals Cat Litter, make sure you keep the transition at a slow pace.
4. Regularly Twitch the Litter
Most of the cat owners complain that crystal cat litter smells a lot. This is because silica gel is made of absorbent sponge particles. And, when it absorbs the urine, it releases the moisture, but it doesn’t lock the odor.
5. Remove Solid Waste
Hygiene is essential; therefore, make sure you remove all solid waste from your cat litter.
6. Have Tolerance
Bear in mind your cat will learn things slowly; it will take time for her to accept the change. Therefore, have patience and always praise your cat when she uses crystal cat litter.

How Green Is Your Kitty's Litter?
Many cat litters work well and may even be perceived as eco-friendly, but you might want to take a closer look. Switching to a truly eco-friendly litter isn’t only good for the environment, it’s good for your cat too.
More than 2 million tons of sodium bentonite clay is mined in the United States each year just for kitty litter. Sodium bentonite can be harmful if cats ingest it, which can happen accidentally when they clean themselves. Likewise, the silica dust in many litters may contribute to respiratory problems for your kitty and you. Fortunately, there are many options, and Weavers Way Across the Way carries a wide variety. Here are some of them:
Swheat Scoop: This natural wheat litter contains no chemicals and no clay, is biodegradable and flushable, doesn’t create dust, is made from a renewable resource and is 100 percent compostable for non-vegetable plants (after scooping). The wheat enzymes naturally neutralize odors.
Blue Naturally Fresh Litter: This is a flushable multi-cat quick-clumping litter made of walnut shells. It is chemical-free, grain-free, clay-free and corn free.
Cedarific Soft Cat Litter: This all natural, biodegradable litter is made with wood fibers grown in the United States. It contains no chemicals, is lightweight and dust-free, and has a soft texture for your kitty’s paws.
Premium Choice Carefree Kitty: This litter company claims its litter “won’t harm the environment,” but it is based on mining. This litter uses bentonite clay from Wyoming and is unscented.
Arm & Hammer Feline Pine: This is a 100 percent natural-pine clumping litter. It contains a “clumping agent” and mineral oil. It creates no dust and contains no artificial scents. This litter doesn’t actually clump; solid waste can be scooped but once liquid hits the litter, the pellets break apart into sawdust. The box can be shaken so the sawdust settles at the bottom, and the litter can be changed when it is close to 90 percent sawdust.
Arm & Hammer “Naturals”: This litter is a corn-based clumping litter, containing a “plant-based clumping agent,” baking soda (of course) and mineral oil.
Cat Tails: 100 percent clay-based litter containing no chemicals. This product packaging does not give information about where the clay comes from.
World’s Best Cat Litter: This is the priciest, but users seem to appreciate that it clumps, is (technically) flushable and dust-free. It is made of whole-kernel corn and comes an all-natural lavender-oil-scented variety. World's Best is sold in Chestnut Hill as well as at Across the Way.
Purina Yesterday’s News: Known as the gentle pellet litter for kittens just having had surgery, Yesterday’s News calls itself the “#1 Recommended Eco-Friendly Cat Litter.” It is made with recycled newspaper, is dust-free, unscented and three times more absorbent than clay.
One thing that needs acknowledging is the potential problems that can result from flushing "flushable" litter. Some cats harbor a parasite called Toxoplasma gondii (especially outdoor cats that eat raw meat), and sewage treatment does not kill this parasite in cat poop. World’s Best's label has a disclaimer from the state of California urging users not to flush the waste, and the Sea Otter Alliance also urges cat owners to never flush cat waste because it may be harmful to marine life. This parasite is also potentially dangerous to people who have vulnerable immune systems such as pregnant women, elderly and people with serious illnesses, who should never handle cat litter at all. So if you choose a "flushable" litter, the best practice is to put it out with the trash.
Obviously, this is a lot to consider! It may take some trial and error to find the best litter for your home, but of course your cats will love you for it.]]> Why Cat Litter Matters

Most of the cat owners complain that crystal cat litter smells a lot. This is because silica gel is made of absorbent sponge particles. And, when it absorbs the urine, it releases the moisture, but it doesn’t lock the odor.
5. Remove Solid Waste
Hygiene is essential; therefore, make sure you remove all solid waste from your cat litter.
6. Have Tolerance
Bear in mind your cat will learn things slowly; it will take time for her to accept the change. Therefore, have patience and always praise your cat when she uses crystal cat litter.

How Green Is Your Kitty's Litter?
Many cat litters work well and may even be perceived as eco-friendly, but you might want to take a closer look. Switching to a truly eco-friendly litter isn’t only good for the environment, it’s good for your cat too.
More than 2 million tons of sodium bentonite clay is mined in the United States each year just for kitty litter. Sodium bentonite can be harmful if cats ingest it, which can happen accidentally when they clean themselves. Likewise, the silica dust in many litters may contribute to respiratory problems for your kitty and you. Fortunately, there are many options, and Weavers Way Across the Way carries a wide variety. Here are some of them:
Swheat Scoop: This natural wheat litter contains no chemicals and no clay, is biodegradable and flushable, doesn’t create dust, is made from a renewable resource and is 100 percent compostable for non-vegetable plants (after scooping). The wheat enzymes naturally neutralize odors.
Blue Naturally Fresh Litter: This is a flushable multi-cat quick-clumping litter made of walnut shells. It is chemical-free, grain-free, clay-free and corn free.
Cedarific Soft Cat Litter: This all natural, biodegradable litter is made with wood fibers grown in the United States. It contains no chemicals, is lightweight and dust-free, and has a soft texture for your kitty’s paws.
Premium Choice Carefree Kitty: This litter company claims its litter “won’t harm the environment,” but it is based on mining. This litter uses bentonite clay from Wyoming and is unscented.
Arm & Hammer Feline Pine: This is a 100 percent natural-pine clumping litter. It contains a “clumping agent” and mineral oil. It creates no dust and contains no artificial scents. This litter doesn’t actually clump; solid waste can be scooped but once liquid hits the litter, the pellets break apart into sawdust. The box can be shaken so the sawdust settles at the bottom, and the litter can be changed when it is close to 90 percent sawdust.
Arm & Hammer “Naturals”: This litter is a corn-based clumping litter, containing a “plant-based clumping agent,” baking soda (of course) and mineral oil.
Cat Tails: 100 percent clay-based litter containing no chemicals. This product packaging does not give information about where the clay comes from.
World’s Best Cat Litter: This is the priciest, but users seem to appreciate that it clumps, is (technically) flushable and dust-free. It is made of whole-kernel corn and comes an all-natural lavender-oil-scented variety. World's Best is sold in Chestnut Hill as well as at Across the Way.
Purina Yesterday’s News: Known as the gentle pellet litter for kittens just having had surgery, Yesterday’s News calls itself the “#1 Recommended Eco-Friendly Cat Litter.” It is made with recycled newspaper, is dust-free, unscented and three times more absorbent than clay.
One thing that needs acknowledging is the potential problems that can result from flushing "flushable" litter. Some cats harbor a parasite called Toxoplasma gondii (especially outdoor cats that eat raw meat), and sewage treatment does not kill this parasite in cat poop. World’s Best's label has a disclaimer from the state of California urging users not to flush the waste, and the Sea Otter Alliance also urges cat owners to never flush cat waste because it may be harmful to marine life. This parasite is also potentially dangerous to people who have vulnerable immune systems such as pregnant women, elderly and people with serious illnesses, who should never handle cat litter at all. So if you choose a "flushable" litter, the best practice is to put it out with the trash.
Obviously, this is a lot to consider! It may take some trial and error to find the best litter for your home, but of course your cats will love you for it.]]> <![CDATA[Choosing Tactile Switches for Your Electronic Applications]]> https://uhm.vn/forum/Thread-Choosing-Tactile-Switches-for-Your-Electronic-Applications--370966 Wed, 10 Nov 2021 14:17:17 +0700 pd11ing10]]> https://uhm.vn/forum/Thread-Choosing-Tactile-Switches-for-Your-Electronic-Applications--370966 Choosing Tactile Switches for Your Electronic Applications
A tact switch is a type of switch that is used every day, but hardly ever seen. Hidden under every key of a computer keyboard, the tactile switch is small and thin, but features high reliability to ensure it will operate for years or even decades.
Tactile switches are small electromechanical devices that are designed to be mounted onto a printed circuit board (PCB). These products are compact with a low profile, meaning these do not rise high above the PCB, a vital attribute when
considering the keyboards use for slim devices such as notebook computers.
Considering that space inside a keyboard is limited, the slim design means that tactile switches must compete with batteries, screens, and other components. To solve this, tactile switches are designed to be positioned side-by-side in a compact array, an attribute important for a keyboard.
The improvements made to the performance of smartphones and tablet computers make them a viable alternative to traditional computers. Tactile switches are small and convenient, suitable for touchscreens that utilize capacitive technology, which harness the electrical properties of the human body to function. For example, when a finger touches the screen, a tiny electrical charge is drawn to the point of contact, and the screen becomes a functioning capacitor. This in turn is detected as a push of a button. Touchscreens are very thin, especially as there are no mechanical moving parts, and the technology is constantly improving to make them thinner still. With the constant improvement of touchscreens, why are manufacturers not making a computer keyboard using capacitive technology? The answer to that question is the feel of keyboard keys, sometimes described using the word haptics. Despite the capabilities of touchscreens, these are hard and unforgiving. While there are many advantages of this smooth, flat surface - these are easy to clean and provide an effective compliment for high definition displays - these provide no feedback to the user, showing why the tactile switch is so useful.
The tactile switch is a mechanical device. The force required to depress the switch, the distance it travels, and the spring as it returns once released all contribute to the “feel” of the switch. The most obvious example of how the haptics of a tactile switch affects the functioning of a device can be found in the computer keyboard discussed earlier. Anyone who uses a computer frequently will know that the movement of the keys on a keyboard can have a real impact on its ease of use, which in turn affects factors including typing speed and operator fatigue. It is the tactile switch that gives the keyboard its feel and familiar clicking noise when a key is depressed.

Offering a combination of low profile, high reliability, and mechanical feedback, tactile switches are suitable for use in many applications. The market for wearable technology is growing quickly, driven by the huge adoption of smartphones and the expansion of high-speed internet services.
Building sophisticated electronics into garments or devices that are designed to be worn requires components such as tactile switches that are not bulky or heavy, creating a design opportunity for wearable technology applications that require innovative visual indicators or control panels.
For example, a soldier wearing smart body armour in a tactical environment or a paramedic using body-mounted cameras might find it unwise to display unwanted light. In situations like these, tactile switches provide the user with both ease of use and a physical indication of correct operation.
Manufacturers tactile switches available for variety of uses, When combined with the huge array of keys and actuators that are available, the tactile represents one of the most versatile switches on the market today.
Why is Micro Switch called a micro switch
Micro switch is an electric switch (patented in 1932) that is actuated by very little physical force. Switching happens at specific positions of the actuator (not like other switches). Relatively small movement at the actuator button produces a relatively large movement at the electrical contacts, which occurs at high speed (regardless of the speed of actuation). Typical durability is from 1 to 10 millions of cycles. This durability is a natural consequence of the design.
Micro switches are not operated by person; it is always some moving part of the equipment. Common applications are detection (e.g. jammed paper in photocopier, the presence of material or product). Other application can be a limit switch (for control of machine tools) or door switch (e.g. fridge).

What is important when using micro switches?
First of all, load size and type. Some types of load have much higher inrush current. E.g. relay has 5 times higher inrush current than nominal, motor 10 times, incandescent lamp 15 times and solenoid even 20 times. On the other hand, for switching small loads, do not use a micro switch for high currents. We recommend using micro switch with gold plated contacts.
For harsh environment (dust and moisture), please use safety micro switch with higher IP rating (up to IP67).
We recommend applying a contact protective circuit to extend contact durability, prevent noise, and suppress the generation of carbide or nitric acid due to arc. The use of a contact protective circuit may delay the response time of the load. Examples of such circuits:
-RC Circuit - in systems with power supply of 24-48V, it is effective to connect the RC circuit in parallel to the load. When the power supply voltage is 100-200V, then in parallel to the contacts (in this case when AC is switched, the load impedance must be lower than the R and C impedance)
-Varistor - the use is very similar to RC circuit, even with those conditions when in parallel to load or contacts. Varistor ensures that no high-voltage is imposed on the contacts.
-Diode - energy stored in the coil is changed into current by the diode connected in parallel to the load. Then the current flowing to the coil is consumed and Joule heat is generated by the resistance of the inductive load. The diode must withstand a peak inverse voltage 10 times higher than the circuit voltage and a forward current as high as or higher than the load current.
-Diode and Zener diode - this method will be effective if the reset time delay caused by the diode method is too long. Zener voltage for a Zener diode must be about 1.2 times higher than the power source.
Ensure that the operating body will work smoothly. The shape of it should be round or oblique - to prevent shocks to the actuator. And of course, operate the actuator of a hinge roller lever or simulated hinge lever type from the right (correct) direction.
Ensure that the stroke to the actuator is set not to exceed the total travel position. If not, the operating body may damage the actuator or the switch itself, and the stress applied to the moving spring inside the switch will increase and then, the durability of the switch may be deteriorated.
And some more details - not to tighten the screws too much - not to deform the body of a switch. Or when soldering, adjust the amount of solder so that the flux does not enter the switch, it can cause contact failure.
Should you choose a rocker switch for your operator interface?
From this calculation, you can work out the expected number of operations over a year so you can find a switch with a lifecycle that can withstand repeated operation over the next 5 to 10 years without failure.
So what exactly is a rocker switch? As the name suggests, rocker switches rock back and forth between the off and on position. When one side is pressed down, the other side will rise up. Most of them provide a ‘positive click’ feedback to let the user know the switch has changed position successfully. Typical applications for these switches include commercial and agricultural vehicles, surge protectors, computer power supplies, industrial assembly lines and many other types of industrial machinery panels.
Some rocker switches with independent circuitry can be backlit to show their presence and function in low light levels. Others can be illuminated to show whether the switch is on or off.
On any operator interface, if you decide to include rocker switches in your design, you’ll need to ensure you have enough space for the switch and information about what the switch is for.
What is a push button switch?
A push button switch is a type of switch which consists of a simple electric mechanism or air switch mechanism to turn something on or off.

Depending on model they could operate with momentary or latching action function.

The button itself is usually constructed of a strong durable material such as metal or plastic. Push Button Switches come in a range of shapes and sizes. We have a selection of push button switches here at Herga.
Push button switches are used throughout industrial and medical applications and are also recognisable in everyday life.
For uses within the Industrial sector, push buttons are often part of a bigger system and are connected through a mechanical linkage. This means that when a button is pressed it can cause another button to release.
Examples of Push Button Switches
Push button switches are present in so many areas across different industries and for different uses here are some examples;
Calculator buttons – a hand held calculator has lots of small push button switches
Reset switches – these are usually small and require a tool to press to avoid accidental operation
Stopping machinery – often around industrial machinery there will be an emergency stop button, sometimes these are located on the wall
Arcade gaming – these are usually brightly coloured to encourage people to play
Slide Switch
A slide switch is a mechanical switch that slides from the open (off) position to the closed (on) position and allows control of a circuit’s current flow without having to manually splice or cut wire.]]> Choosing Tactile Switches for Your Electronic Applications
