Plastics are electrically insulating (with the exception of conductive polymers), and static electricity is generated when plastic comes into contact or rubs against other materials. anti static agent If the accumulated static electricity is not eliminated in time, it may cause electrostatic adsorption, dust collection, cremation discharge, etc., resulting in combustion and explosion.
The methods of eliminating static electricity include conductive material (conductive carbon black, metal powder, etc.) filling method, conductive device method, antistatic agent, etc.
Antistatic agents (surfactants) are used to eliminate static electricity in plastic products. There are external coating method and internal addition method. The former has poor durability, is mostly used for temporary or short-term electrostatic treatment, and has a narrow scope of application; the ionic and non-ionic surface activities used in the internal addition method are selected according to the different structural characteristics of the base resin.
