Anti-static overalls knowledge
During the normal production activities, the operator wears clothing between the external media surface (such as work surface, chair, tools, appliances, etc.), between the layers of clothing, between the underwear and the skin, until the sole and the ground when walking Between the pings, clothing and shoes are charged due to frequent contact separation and friction, especially when wearing high-insulation chemical fiber clothing.
The static charge of the clothing and shoes is gradually dispersed to the entire surface according to the law of the charge on the medium, and a certain static voltage is formed on the garment when the balance is reached. Of course, since the human body itself is a good conductor, the charging of the clothing will cause the human skin to be charged around the body due to electrostatic induction, and a certain static voltage is also formed. Thus, for the operator, there are two possible discharge channels; one is the discharge between the fingertip (skin) and the ground conductor, and the other is the discharge between the work clothes and the ground conductor.
Both of these discharges can cause damage to static-sensitive devices. Although the anti-static wristband eliminates the first type of discharge hazard, it does not eliminate the second discharge hazard. This is because the wristband can only eliminate static electricity on the human skin as a good conductor, and it is impossible to leak static electricity on the more insulative clothing. Assembly line, tube bender, LED high bay lamp shell, woolen factory, Tianjin discount ticket, people often only notice the elimination of static electricity on human skin, and neglected or did not pay enough attention to eliminate static electricity in clothing, which needs improvement.
