Plasma equipment for surface treatment of PET film materials

The plasma cleaning machine can improve the surface roughness of the film by etching and introducing a large number of oxygen-containing polar groups on the film's surface to improve the hydrophilicity and surface energy of the PET film. Surface modification of PET film materials. The plasma cleaner also improves the surface energy of the PET film material. Through plasma cleaning machine treatment, a large number of oxygen-containing polar groups can be introduced to the surface of the PET film, thereby increasing the free energy of the surface of the PET film, improving its surface wettability, bondability and printability.

Using the atmospheric jet cyclone plasma cleaner to process the PET film material, it can observe that with the increase of the treatment time of the plasma cleaner, some irregular flake-like structures appear on the surface of the PET film. The roughness of the film surface also increases. The surface of the PET film also shows a large area of the white fine textured structure, and these rough structures are composed of nano-scale fine particles. The plasma cleaner has a specific etching effect on the PET film.

Plasma cleaning is a high-precision dry cleaning method. The surface of the workpiece is treated by chemical reaction or physical action to realize the removal of contamination at the molecular level (generally, the thickness is 3~30nm) and improve the surface activity. Corresponding to different pollutants should use different cleaning processes to achieve the best cleaning effect.
