What is the principle of pe antistatic film?

2020-08-10

PE antistatic film is a kind of stretch film used to prevent static electricity generated by friction. It is widely used in packaging films for electronics, electrical appliances, and power transmission and transformation equipment to prevent static electricity from damaging human products and work sites. The anti-static film is made by adding imported anti-static agent to the PE raw material to make the surface resistance reach 10-10 Ω. The friction does not generate static electricity. After high-temperature shaping, it is durable and has a good anti-static effect. Avoid electrostatic damage to human products and work sites.
The principle of pe antistatic film: an antistatic agent is added to the protective film substrate or glue. This antistatic agent can effectively absorb the "moisture" on the surface of the product and the air, and then the water can be obtained. Neutralize with static electricity. So as to achieve antistatic effect. This is relatively simple. Most of the protective film is made of PP/PE raw materials. Before blowing the film, add an antistatic agent and mix it uniformly, plasticize it with a screw, and then blow the film. After the product comes out, because the antistatic agent is distributed in the resin, and the antistatic agent is a low-molecular-weight surfactant, it is hydrophilic and hygroscopic, and it is easy to migrate from the resin to the surface of the product. The layer of water molecules thus achieves the effect of discharging static electricity.
PE antistatic film is mainly used for LCD liquid crystal displays, LCD backlights, laptop computers, high-gloss plastic plates, ordinary plastic plates, various plastic sheets, organic or inorganic glass lenses, various metals, electroplating plates, stainless steel, aluminum profiles , Steel-plastic profiles, aluminum-plastic panels, glass panels. The biggest advantage is that the protected products are not polluted, corroded, scratched during production, processing, transportation, storage and use, and protect the original smooth and shiny surface, thereby improving product quality and market competitiveness.
The above is the introduction to the principle of pe antistatic film. Finally, I am Jiangshan Jianlan Plastic Film Co., Ltd. If necessary, you can consult me.
