Plasma pretreatment can remove the oil and dust on the surface of the material and make the surface energy of the material higher. The cleaning effect of plasma cleaning treatment technology can remove the surface oil, and the electrostatic action of plasma can remove the surface attachment. The dust particles on the surface, and the chemical reaction improves the surface energy. The integration of these aspects makes the plasma pretreatment process become an efficient means, which usually does not need to carry out plasma pretreatment, additional cleaning procedures and bottom coating treatment. Plasma pretreatment can ensure strong adhesion of metal materials such as aluminum, plastic materials such as PP or EPDM or other materials. Plasma processing technology is used to achieve reliable and durable bonding.
