First, the resistance of antistatic materials and insulating materials is different. Generally speaking, the resistance of insulation is greater than 1012Ω, while the resistance of antistatic is between 106Ω and 1012Ω. The insulating rubber is non-conductive, and the anti-static material is conductive, but the resistance value is relatively large, and the standard requirement is between 10^6 and 10^9.
Secondly, the performance of anti-static shoes and insulating shoes is different. Anti-static shoes are made of anti-static materials added to the sole. Anti-static shoes have a weak conductive function, which can guide the excess electric charge of the human body to the ground, avoid the accumulation of electric charges and cause electrostatic discharge, so as to eliminate the static electricity of the human body. . The sole of the insulating shoe is made of non-conductive insulating material, which can isolate the human body from the ground, so that even if the human body touches the conductor, there will be no electric shock accident.
Finally, anti-static shoes and insulating shoes have different applications. Anti-static shoes are generally used in precision electronics, components and other electronic enterprises, optical instruments, pharmaceutical companies, etc. During the use of anti-static shoes, friction does not generate static electricity, so that electronic products can be protected from static electricity. It is to protect the human body from the influence of electricity, and there are no special requirements for the ground and protective clothing. It is generally worn by electricians to prevent electric shock caused by step voltage, and also to prevent electric shock accidents caused by ground conduction.
