How about injection molded barrelsAntistaticWhat about it?Antistatic plastics require that their volume resistivity must be reduced to less than 1012 ·cm, and conductive plastics require that their volume resistivity be less than 106 ·cm or conductivity greater than 2s cm. of plastic productsAntistatic methodsThere are many kinds of them, but they can be summarized as follows.
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 inhibiting the generation of electrostatic charge and promoting the leakage of electric charge.
3) The polymer structure is changed by blending with structural conductive polymer materials or by grafting and copolymerization, so that it has more polar groups or ionization groups, which reduces the resistivity and increases the conductivity.
4) Use strong oxidant oxidation or corona discharge to treat the surface of plastic products to improve the surface conductivity of the material.
5) Apply a conductive coating or a layer of conductive film on the surface of the product.
6) Add conductive fillers, such as graphite, carbon black, metal or metal oxide powder, etc., to the plastic, and disperse the conductive filler into the plastic through compounding, making it a composite conductive plastic.
7) AddAntistatic agents, antistatic treatment of the material to activate its surface and improve the surface conductivity of the material.
These methods have their own characteristics and limitations, but in comparison, adding antistatic agents is the simplest and most effective, low-cost, practical and most widely used.
