ESD Work clothes static electricity generation and harm
Clean room clerk in the normal production activities, between the clothing worn and the external medium appearance, between the layers of clothes, between the underwear and the skin, until the sole and the floor between walking, the city is often separated by the touch And conflicts that cause clothing and shoes to be charged, especially when wearing high-insulation chemical fiber clothing, which will increase the electrification.
The static charge of the clothing and shoes is gradually dispersed to the entire appearance according to the rule of the charge on the medium, and when it reaches equilibrium, it constitutes a certain static voltage on the clothing. Therefore, it is very necessary to work in anti-static clothing.
Of course, since the human body is a good conductor, the charging of the clothing will cause the human body to be charged by the static electricity, and it also constitutes a certain static voltage. So for the operator, there are two capable discharge channels; one is the discharge between the fingertip (skin) and the ground conductor, and the other is the discharge between the task suit and the ground conductor. Both of these discharges can pose a hazard to electrostatic sensitive equipment.
Although the anti-static wristband can eliminate the first type of discharge risk, it does not eliminate the second discharge risk. This is because the wristband can only eliminate static electricity on the human skin as a good conductor, and can not leak static electricity on the more insulating clothing.
Everyone often only notices the elimination of static electricity on human skin, and neglects or does not pay great attention to eliminating static electricity in clothing, which is an improvement in demand.
In general, the static electricity carried by different workers is also different. So choose the appropriate anti-static suit for different jobs.
