To better understand, we need to learn what is clean room? And why must use standard products for clean room use?

Clean rooms are a working environment in which regulatory restrictions are set to control airborne dust concentrations not to exceed specified levels. Always controlling and eliminating sources of clean room pollution that could be people, equipment, and machines to ensure that they always maintain the standards set for the cleanliness level allowed. In order to easily monitor dust concentration or control dust particles to the specified limit in the environment, the enterprise has set up protocols and standards for employees and products to control the environment in clean room. And to maintain that clean level is stable, the pollution sources need to be identified and the specifications of the product must meet the requirements of the clean room level (Class 10, Class 100, Class 10,000). , etc.).

 What can affect or destroy the quality of the product is the material and the surface is contaminated by contamination. Therefore, it is important to identify and control the sources of pollution, and can often be controlled on an individual basis (from operators, technicians, workers and visitors to and from factories). ...).

You know, our human body is one of the worst contaminants. Because dirt particles often cling to oil on the skin, body hair, skin flakes, body fluids, cosmetics, etc. can lead to serious clean room pollution problems. But now, we have a way to solve those worrisome problems, by using clean room specials, including antistatic gloves in clean rooms. Gloves served with a function are quite important because it comes in direct contact with the product and the process.

So how are clean room gloves used? First, it must be mentioned that it is used for pollution control in regulated industries. In addition, it is used in critical production environments in very important applications to minimize particles such as laboratories, automotive paint lines, pharmaceuticals, biotechnology research facilities. , aerospace, electronics and semiconductors, circuit boards, health care (USP 797) and biomedical equipment manufacturing activities. The following are the types of gloves that are on the market and are commonly used today:

1. Clean room gloves single-use:
It will not look like a test glove, does not contain fillers (chemicals that cause obsolescence) or polymer coating to stain products. Commonly used in clean rooms include: latex gloves, Nitrile gloves and Co-polymer Vinyl gloves. Clean room disposable gloves are certified and are usually packed in poly bags.

Both clean room Nitrile gloves (artificial rubber gloves) and cleanroom Latex gloves (natural rubber gloves) will be chlorinated and washed with deionized water (DIW) to remove surface particles. face, powder residue, metal content is very low and suitable for very strict clean room use. Both nitrile and latex gloves are available with textured surfaces of varying lengths and thicknesses to suit the requirements of the plants used.

For a clean room type Latex glove is used once to provide a fit, flexibility and good elasticity, but it will have a strong latex smell and may not be suitable for sensitive individuals or products. with latex protein.

For single-use Nitrile gloves, it provides good fit, good elasticity and non-allergy to natural rubber components. They have some very low friction properties that are important for ESD sensitive products. Nitrile gloves also tend to have better chemical resistance properties than Latex gloves. Nitrile gloves are packed in PVC boxes and clamshell boxes. PVC boxes reduce cardboard fibers and make distribution easier.
Vinyl Co-polymer disposable clean room gloves can be quite clean if produced in a clean environment. lower fit or elasticity than latex or Nitrile gloves, but brings cost-effectiveness. Vinyl gloves provide good chemical resistance and have antistatic properties.

2. Knitted gloves used in clean rooms
Usually used for packaging, inspection or assembly in Class 10,000 Clean Rooms or many other clean rooms. Its structure consists of low yarns and knitted fabrics such as polyester gloves, nylon gloves, nylon / carbon fiber gloves or copper fibers, 40 Denier Tricot and cotton gloves. One of these types of gloves will have special coatings such as Polyurethane (PU) coating, nitrile coating, PVC coating, etc. to provide more grip, abrasion resistance or puncture resistance. It has a special seamless structure so it will create an advantage for it to be a non-torn, non-running, navel-free glove and comfort for employees to wear. There is also a half-finger knitted glove that is usually worn under the outer glove to absorb sweat and increase comfort. In most cases, the color cuffs are color-coded for easy size identification.

Types of popular seamless knitted glove designs:

Sturdy SHIZU nylon gloves: woven with special non-fibrous yarns and a continuous nylon yarn.
Seamless Dyneema Gloves SHIZU with PU: It has Dyneemal and hand-coated polyurethane coating. Dyneema is one of the most powerful fibers in the world with a characteristic smoothness that prevents them from puncture and cutting. This sophisticated SHIZU knit glove is not hardened with great dexterity, making them ideal for working with everything from circuit boards to food.

SHIZU seamless knit nylon gloves: smooth polyurethane (PU) coating on fingers and palms provides excellent puncture resistance and abrasion and tactile. Nylon fiber will absorb sweat and keep hands cool and comfortable. Can be worn under gloves as a lining or alone as an inspection glove. Color coding for size identification. Ideal for product processing, finishing and assembly, electronic assembly, photography labs and computer manufacturing ...

3. Special clean room gloves:
Depending on the clean room functions, the clean room gloves are designed with appropriate corresponding features. Like clean chemical resistant gloves, cold gloves, anti-cut clean room gloves, touch screen gloves, clean room heat gloves, ...

14 inch dry heat gloves SHIZU: Electrostatic static protection 10 ^ 6 to 10 ^ 9. The outer shell is woven from an exclusive fiber blend, selected for excellent heat resistance, plus extremely low and extremely low grain properties. The middle layer is 100% pure knit wool with a high pile for excellent insulation. Completely lined with nylon to minimize the generation of fibers and particles in the process of donation and removal, when the opportunity is greatest to produce fibers and granules. These gloves are 100 compatible clean rooms.

4. ESD gloves:

ESD electrostatic gloves: will help you solve the problem of electrostatic pollution in electronics, aerospace, automotive, paint lines, ammunition and semiconductor industry. The handling of sensitive, sensitive parts such as films, electronic devices, circuit boards and components will often use this type of glove during the clean room work. Because the working environment is usually static, it will easily lead to dust and dirt in parts or it may create static electricity that could damage employees or products. Electrostatic fiber (ESD) mixed with low nylon yarn will reduce static accumulation on the glove surface to improve the best performance. Here are some common ESD gloves used in clean rooms:
Static seamless gloves disperse static SHIZU with PU palms: Working gloves woven with seamless nylon / carbon fiber are woven with high quality, no fiber, made of high quality material for electronics.
