Antistatic Technology Of Polymer Materials

1. Electrostatic hazard

Everything has two sides. Static electricity is good and will naturally cause harm. Static electricity is produced by harm. That is to say, when two solids with different physical states contact and rub against each other, charge redistribution will occur on their respective surfaces. After re separation, at this time, each solid surface will carry more positive (or negative) charges than before contact. This phenomenon is called static electricity. Electrostatic phenomena are very common in some production, processing and use processes, such as polymers. However, once the resistance is too high due to static electricity, its volume resistivity is about 1010 ~ 1020d, · cm, which is easy to cause great harm. Dust, bacteria and electric shock accidents in medicine, fires in mines and oil, and IC damage in electronic industry are all caused by improper generation of static electricity, which requires us to further research and develop the antistatic polymer material technology.

2. Meaning of antistatic polymer

The antistatic property of polymer is that a lot of charges are gathered on the surface of polymer, which depends on the discharge property of polymer, and this property is transmitted through the body or conductor like air, in which surface conduction is the main way. Polymer anti-static technology uses this conduction way to stop static electricity. Antistatic polymer materials are generally made by mixing various chemical additives Generally, it can effectively prevent or eliminate static electricity on the surface of materials, so as to improve the utilization rate of objects, which is the essence of antistatic technology of polymer materials.
