The importance of wearing anti-static clothing
With the popularization of computers and electronic products, more and more manufacturers have begun to take anti-static measures, and anti-static clothing is one of the important measures. This is because the human body is the source of the largest static charge in the production hall. The amount of static electricity that can be perceived varies depending on factors such as the height of the body and the size of the foot. For example, a person with a large body and a large foot size needs to accumulate a charge to generate electricity of the same amount. In addition, the fabric, sole material and weather conditions of the garment can also affect the amount of static electricity. For example, when the climate is dry, static electricity is easily generated.
Static electricity of around 2-4 kV is harmless to most people. However, electronic components are damaged by tiny static electricity of only a few volts. It is estimated that 8%-33% of product damage is caused by static electricity. The anti-static suit prevents damage to electronic components and prevents fire or explosion when operating flammable gases and liquids. Once the static electricity is not controlled, it may cause a series of losses, especially in the semiconductor and electronic products industry, the human body static electricity is the biggest threat, a bending action, the generated static electricity is enough to break through the chip, causing product damage, equipment failure, Loss of work and product repair. The harm of static electricity has certain concealment. Many times, static electricity damages the product, but it does not completely damage the product. Therefore, it is not sure whether there is any problem during the factory inspection, but the product quality problem appears in the process of user use. It is the reason why many domestic electronic products are unstable in quality and have a short service life. Therefore, it is extremely urgent to solve the problem of static electricity, and workers in these industries are required to wear anti-static clothing.
The antistatic suit is made of a fabric with electrical conductivity, and the static electricity is neutralized by adding conductive fibers or using a finished fabric. Many antistatic garments use a wire or grid wire in a cotton, polyester or blended fabric. Generally, a dense grid (5mm x 5mm) will be more antistatic than a loose grid (20mm x 20mm), which can effectively suppress static electricity in the human body and eliminate or reduce the electrostatic discharge hazard.
