How does plastic resist static electricity?Antistatic plastics require their volume resistivity to be reduced to less than 1012Ω·cm, while conductive plastics require their volume resistivity to be less than 106Ω·cm or their conductivity to be greater than 2S/cm.There are many antistatic methods for plastic products, and there are roughly the following in summary.
1) Use conductive devices to eliminate static electricity during the processing of plastic products.
2) Increasing the air humidity in the processing and use environment of plastic products is conducive to suppressing the generation of electrostatic charges and promoting the leakage of electric charges.
3) The polymer structure is changed by blending with structural conductive polymer materials or by grafting and copolymer, so that it has more polar groups or ionized groups, which reduces the resistivity and increases the conductivity.
4) Use a strong oxidizing agent to oxidize or use corona discharge to treat the surface of plastic products to improve the surface conductivity of the material.
5) Apply a conductive coating or a composite layer of conductive film on the surface of the product.
6) Add conductive fillers, such as graphite, carbon black, metal or metal oxide powder, to the plastic, and disperse the conductive fillers into the plastic through mixing to make it a composite conductive plastic.
7) Add antistatic agents, perform antistatic treatment on the material, activate its surface, and improve the surface conductivity of the material.
These methods have their own characteristics and limitations. In contrast, adding antistatic agents is the simplest and most effective, with low cost, strong practicality, and the most common application.
Anti-static plastic barrels use plastic anti-static agents, which are suitable for anti-static treatment of plastics without affecting transparency. The resistance value can reach the power of 10 8-10 11, which meets environmental protection requirements, FDA, ROHS, and REACH. It has good compatibility with raw materials and is not affected by temperature and humidity. No precipitation.It can effectively prevent the final product from absorbing dust, prevent the product from affecting the appearance and performance of the product due to dust pollution, prevent the risk of fire and explosion caused by discharge, and curb the damage caused by static electricity.
