Static electricity is a phenomenon we often encounter in our daily life, which is an objective natural phenomenon. Static electricity is the accumulation of positive and negative charges on two objects when two kinds of materials with different dielectric coefficients are rubbed. When two objects come into contact, one tends to attract electrons from the other, so they form different charging potentials. There are many ways of generating static electricity, such as contact, friction, etc. Simply put, the contact friction or induction between the human body's action and other objects can generate several thousand volts or even tens of thousands of volts of static electricity, but this static electricity is short time, low electricity and small current, acting on the human body will have the feeling of being instantly shocked. Electrostatic phenomenon has caused serious harm in many fields, such as the field of electronics. The harm caused by static electricity is obvious. It can easily break down expensive electronic devices. Static electricity can cause rocket and satellite launch failure, interfere with the operation of air vehicles; Static discharge, especially in petrochemical enterprises, will cause huge losses. According to statistics, more than 30 serious fire and explosion accidents caused by static electricity have occurred in petrochemical enterprises in China in recent years. Therefore, the work of electrostatic protection is a long-term system engineering. Any mistake or omission in any link will lead to the failure of electrostatic protection. With the rapid development of science and technology, electrostatic protection technology has become an urgent problem to reduce the loss caused by electrostatic hazards in electronics industry, petroleum industry, weapons industry, textile industry, rubber industry, aviation and military fields.
Static electricity is everywhere, cannot avoid, but can prevent or reduce the harm that static electricity produces. Ptfe board has many excellent properties such as corrosion resistance, high and low temperature resistance, aging resistance, etc. Ptfe board has played a decisive role in the national economy fields such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridge. However, it also has electrostatic phenomenon, in special occasions, we must pay attention to the application of anti-static technology. Deqing new duoling fluorochemical co., ltd. is based on this requirement to design anti-static polytetrafluoroethylene plate, through adding anti-static agent, to help the use of polytetrafluoroethylene plate electrostatic dissipation, prevent the generation of charge ions, friction is not easy to charge.
Prevent the generation of static electricity, reduce the harm of static electricity, so as to expand the use range of ptfe board. At the same time, aiming at the defects of pure ptfe plate, such as poor creep resistance, wear resistance and large linear expansion coefficient, we modified the pure ptfe material according to the use conditions. Antistatic ptfe plates are black in appearance, which is different from other black ptfe plates by adding graphite, carbon fiber, molybdenum disulfide or other colorants. In perfectly retain the original base material at the same time, on the basis of the inherent physical properties of anti-static teflon plate because of the added other modified materials to make its own performance is improved greatly, and can prevent and prevent electrostatic phenomenon occurs, make ptfe material prolong service life, better application in the fields of various kinds of special requirements. At the same time, we can also produce anti - static ptfe tube, anti - static ptfe stick, anti - static ptfe shaped parts and anti - static ptfe film.
