What is corona discharge treatment?
It is used as a pretreatment for PP, PE, POMoPS, fluororesin, coating, and painting!
"Corona discharge treatment" refers to the process of generating electrons using a high-frequency high-voltage device and colliding them with the surface of a material. By colliding, various strongly polar functional groups such as carbonyl groups are generated on the surface of the material, improving adhesion. Corona discharge treatment is used as a pretreatment for materials such as PP, PE, POM, PS, fluororesins, coatings, and painting. [Steps to Generate Corona Discharge] (1) Application of high-frequency high voltage to the electrodes (2) Breakdown of insulation in the air layer between the electrodes and the insulator (3) Generation of corona discharge *For more details, please refer to the related link page or feel free to contact us.
