The human body is the most common source of electrostatic hazards. The easiest way to eliminate static electricity from the human body is to take grounding measures on the human body. Wear anti-static shoes and use anti-static floor (anti-static mats, carpets, etc.) and anti-static socks anti-static insoles, etc., so that static electricity can be directed from the human body to the ground, thus eliminating static electricity.
Technical requirements for anti-static shoes
1, electrical performance
1.1 Anti-static shoes are tested according to Appendix A of this standard, and the resistance value ranges from 100kΩ to 1000MΩ.
1.2 Conductive shoes are tested according to Appendix A of this standard, and the resistance value is not 100kΩ.
2, physical and mechanical properties
2.1 anti-static shoes, conductive shoes should comply with QB1002 ~ 1005 regulations.
2.2 anti-static cloth surface rubber shoes, conductive cloth surface rubber shoes should comply with HG/T2495 regulations.
The utility model is characterized in that: the sole comprises an outermost RB bottom containing conductive carbon black, and the bottom of the sole is sequentially covered with a conductive cloth and a conductive layer, and each layer is covered with a conductive glue.
Production method: firstly, the RB bottom with conductive carbon black is prepared, and combined with the upper and the like to make a shoe, and then conductive layers and conductive wires are used to make conductive bottom layers on the bottom layers of the shoes. After being placed in the shoe in turn, the finished product can be produced.
Advantages: The structure is novel and practical, has a reliable conductive connection structure, can effectively prevent static electricity, avoid various accidents caused by static electricity, protect the safety of life and property and people's health.
What issues should be paid attention to when using anti-static shoes?
Anti-static shoes should have anti-static 祙/insole when worn, and work on anti-static ground to make the static electricity brought by the human body to the earth. If any part of the resistance is too large or disconnected, the human body will be exposed to harmful static electricity. Therefore, in important departments, there should be a human body resistance tester to detect whether the shoes/shoes/insole worn by the human body and the total resistance of the human body can cause leakage static electricity.
Anti-static shoes in use in human safety issues
Only from the perspective of anti-static, the total resistance of the human body to ground is as small as possible, but the minimum value is limited by safety. The human body must have a certain value of ground resistance so that metal equipment or devices and power frequency occur in case In the case of a shorted power supply, the resistor can limit the current flowing through the operating human body. The minimum value should not be less than 105Ω. Generally, the current limiting resistance of the wristband is 1MΩ. The minimum resistance of the antistatic shoes should be no less than 105Ω and no more than 109Ω.
