With the development of modern industry, the working environment faced by workers is becoming more and more strict and uncertain. At this time, the use of labor protection products is more important. Taking safety shoes as an example, they can effectively provide protection for workers’ feet, and provide certain protection against different hazards in different working environments to avoid unnecessary injuries. Therefore, safety shoes are an essential part of workers’ daily work. Many people confuse anti-static safety shoes with electrical insulation safety shoes when purchasing safety shoes. This is very dangerous and can easily cause accidents. Therefore, we need to understand the difference between these two types of safety shoes.
Static electricity is an objective natural phenomenon that can be produced in many ways, such as contact, friction, induction between electrical appliances, etc. Static electricity is characterized by long-term accumulation, high voltage, low power, low current and short action time. The action of the human body or the contact, separation, friction or induction with other objects can generate thousands of volts or even tens of thousands of volts of static electricity. Static electricity can cause serious harm in many fields, such as electronics industry, semiconductor, petroleum industry, weapon industry, textile industry, rubber industry, and aviation and military fields. Friction electrification and human body static electricity are two major hazards in the electronics industry, which often cause unstable operation or even damage to electronic and electrical products. Because of this, anti-static technology is widely used in the materials of labor protection products in various industries, mainly through the following three ways: ① Form a conductive layer on the surface of the material, thereby reducing its surface resistivity, so that the static charge that has been generated can be quickly Leakage; ② endow the surface of the material with a certain degree of lubricity and reduce the coefficient of friction, thereby inhibiting and reducing the generation of static charge; ③ build a conduction path so that charged particles can come into contact.
