How to safely use anti-static clothing in electronics factories
The electronics factory is the main place where anti-static clothing is worn. In the electronics factory, how can we use anti-static clothing safely? Usually, people tend to only pay attention to the operation of eliminating static electricity on human skin, but ignore or simply do not pay enough attention to the work of eliminating static electricity in anti-static clothing. This needs to be strictly improved, in order to effectively prevent the human body from being infected with static electricity. Hazards of static electricity discharge! Then, we should coordinate and operate the anti-static clothing that must be worn for effective protection.
During normal production activities, electronics factory operators will be separated and separated due to frequent contact between the anti-static clothing they wear and the surface of external media, between each layer of clothing, between underwear and skin, and between the soles of shoes and the floor when walking. Friction causes clothing and shoes to become charged, especially when wearing chemical fiber clothing with high insulation properties, which will aggravate the electrification. The local static charge on clothing and shoes gradually disperses to the entire surface according to the charge dispersion law on the medium, and when it reaches equilibrium, a certain electrostatic voltage is formed on the clothing. Since the human body itself is a good conductor, the charging of clothing will cause the human skin to be charged due to electrostatic induction, and also form a certain electrostatic voltage. Therefore, for operators, there are two possible discharge channels in the standard style of anti-static clothing. It is generally believed that wearing pure cotton work clothes can prevent the accumulation of static electricity in anti-static clothing, so it is safe. This view is one-sided in reality. The charge capacity of cotton fabrics is even higher than that of some chemical fiber fabrics, so in dry climate areas, you cannot expect to use pure cotton products to eliminate the static hazards of anti-static clothing under any circumstances. One is the discharge between fingertips and grounded conductors, and the other is the discharge between work clothes and grounded conductors. Both discharges may cause damage to electrostatically sensitive devices. Although anti-static can eliminate one type of discharge hazard, it cannot eliminate the two. A discharge hazard.
