What is the difference between anti-static shoes and insulated shoes?
Anti-static is a static electricity that needs to be collected by people. Through the electrical conductivity of anti-static safety shoes, the static electricity of the human body is introduced into the earth. Insulation requires the human body to be isolated from the conductor. The function of the insulating shoe is to isolate the human body from the conductor of the earth. Therefore, the shoes of these two functions must not be mixed!
Generally, the resistance is greater than 1012 Ω for insulation, and the greater than 106 Ω is less than 1012 Ω for anti-static. The insulating rubber is non-conductive, the anti-static material is electrically conductive, but the resistance value is relatively large, and the standard requirement is between 106 and 109. Antistatic materials are mostly used in the electronics industry. During use, friction does not generate static electricity, which serves to protect electronic products.
The anti-static safety shoes are made of anti-static material added to the sole. The anti-static shoes have a weak conductive function, which can discharge excess electric charge of the human body through the human body, and guide the earth to avoid electrostatic discharge and accumulate electrostatic discharge, thereby eliminating The role of static electricity in the human body.
The insulative safety shoe sole is made of an electrically non-conductive insulating material, which isolates the person 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.
Antistatic is a measure of the coefficient between insulation and conduction. Anti-static safety 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 safety shoes can prevent people from being exposed to static electricity. Anti-static safety shoes are used to prevent accidents caused by static electricity. It is equipped with anti-static safety shoes and conductive wires on the sole to introduce static electricity from people into the ground. Generally used in special gas, petroleum, petrochemical and other inflammable and explosive places. Because it is mainly used to release the static electricity generated by the human body, anti-static safety shoes are not only used in the petrochemical industry, but also widely used in electronic companies such as precision electronics and components, optical instruments, pharmaceutical companies, and so on.
Insulated safety shoes can only be used by maintenance electricians during work to reduce the risk of electric shock. It is generally worn by an electrician to prevent electric shock due to striding voltage and to prevent electric shock due to ground conduction.
