Anti-static shoes failed to test, all caused by insoles
Anti-static shoes are special work shoes worn by production workshops and advanced laboratories of the microelectronics industry such as electronic semiconductor devices, electronic computers, electronic communication equipment, and integrated circuits to reduce or eliminate static electricity hazards. However, the anti-static shoes in the special labor protection footwear have a much higher detection failure rate than other footwear. What is the reason?
When testing the static shoes, it was found that the electrical performance test failed under dry conditions, which was the primary factor that caused the high rate of anti-static shoes. This is also an important item for anti-static shoe performance testing. It was found in the electrical performance test of antistatic shoes that at present, the electrical performance of the antistatic shoe outsole and midsole produced by most enterprises can meet the requirements of the standard. However, the electrical performance test requirements for anti-static shoes include movable pads in the shoes. Combined with the pass rate of the anti-static shoe electrical performance test in recent years, it is found that the big factor affecting the anti-static shoe electrical performance is the quality of the anti-static shoe insole. No matter what kind of material is the antistatic insole, the principle of conduction is generally through a conductive medium, through the midsole conductive electrode or antistatic material to connect the outsole, and the static electricity of the human body is introduced into the ground.
The key to the performance of anti-static work shoes is the quality of anti-static insoles. If the product is not qualified just because of a pair of insoles, it will outweigh the gain. Anti-static shoes are common work shoes. When purchasing anti-static shoes, companies should pay special attention to selecting anti-static insoles to avoid unnecessary losses.
