What are qualified anti-static shoes
When the human body rubs against chemical fiber clothing or contacts plastic products, static electricity will be generated. When wearing anti-static clothing, its partner - anti-static shoes must also appear, because by wearing anti-static shoes, the human body is "connected" with the earth. grounding" for the purpose of electrostatic discharge. So how can buyers choose qualified anti-static shoes?
The surface resistance of anti-static shoes is stable between the 6th power of 10 and the 9th power of 10, and the volume resistance is stable between the 5th power of 10 and the 8th power of 10. The surface resistance and volume resistance of anti-static shoes can be detected by Haoyatong electrostatic testing equipment, which can determine whether the anti-static index of shoes is qualified.
Qualified anti-static shoes should also be used correctly. Generally, the resistance test should be carried out once no more than 200h during the wearing process. If the resistance is not within the specified range, it cannot be used as anti-static shoes. The commonly used material of anti-static shoes, wearing anti-static shoes is one of the effective and reliable discharge methods for the operator's electrostatic charge. Due to the requirements of the manufacturer, the current anti-static shoes not only need to have anti-static function, but also need to use Materials with low dust generation to suppress the dust generated by people walking around in the clean room. Anti-static shoes are generally made of PU or PVC materials that disperse static electricity to make soles, which are integrally formed on the upper surface, and then reinforced on the line. The finished shoes are overall beautiful, generous and sturdy. In particular, PU anti-static shoes have superior wear resistance, which is more than 5 times more wear-resistant than ordinary rubber shoes.
In short, only the selection of qualified anti-static shoes can achieve the purpose of electrostatic discharge, successfully control the adverse effects of human electrostatic charge on the production line and the human body, and improve product qualification.
