Anti-static shoes are a kind of work shoes worn by the production workshops and advanced laboratories of microelectronics industries such as electronic semiconductor devices, electronic computers, electronic communication devices and integrated circuits to reduce or eliminate static electricity. Anti-static shoes can guide static electricity from the human body to the earth, thus eliminating the static electricity of the human body. At the same time, it can effectively suppress the dust generated by the people walking in the clean room. The anti-static shoes can eliminate the static electricity of the human body and prevent the current below 250V. Protective shoes for electric shock are mainly used in places where it is possible to prevent any static electricity hazard such as burning or explosion due to static electricity from the human body. Pay attention to the clean, waterproof and moisture-proof products. In the process of wearing, generally no more than 200h should be tested for resistance once, if the resistance is not within the specified range, it can not be used as an anti-static shoe.
Insulated shoes are a kind of safety shoes made of insulating materials. The applicable range of electric insulating shoes, the new standard clearly points out: electric insulating shoes and cloth-covered electric insulating shoes with the test voltage less than 15KV, applied in the working environment of power frequency (50-60F) below 1000V, test electric power above 15KV The city's electric insulating rubber shoes are suitable for working frequency above 1000V. The term "insulation" refers to the encapsulation of a charged body with an insulating material to isolate a charged body or a conductor of a different potential so that current can flow in a certain path. Good insulation is a necessary condition to ensure the normal operation of equipment and lines, and is also an important measure to prevent electric shock accidents. Insulation often plays other roles: heat dissipation, mechanical support and fixation, energy storage, arc extinguishing, moisture protection, mildew resistance, and protection of conductors.
The anti-static shoes have a weak conductive function, so that the static-static anti-static shoes accumulated on the human body can be introduced into the ground. The insulated shoes are made of an electrically non-conductive insulating material, and the shoes are used to isolate the human body from the earth, so that even if the person is in contact with the electric conductor, there is no accident that the electric current enters the ground through the body. The place where the anti-static shoes are used should be an anti-static floor, and the place where the conductive shoes are used should be an electrically conductive floor.
Anti-static shoes can be worn by ordinary people. Especially in the northern regions, the air is dry in winter, and people are easy to accumulate static electricity. Wearing anti-static shoes can prevent people from being exposed to static electricity. Insulated shoes are only used to repair electricians at work to reduce the risk of electric shock.
