Sheet Plasma Surface Processor to promote the adhesion of coating materials:
The sheet plasma surface processor consists of a plasma generator, a dielectric electrode tube system and a discharge platform. The high voltage and high frequency energy generated by the plasma generator generates low temperature plasma in the glow discharge activated and controlled by the electrode tube, and the plasma is sprayed on the workpiece surface.

CRF Plasma Surface Processor
When the plasma meets the surface of the object to be treated, chemical reactions and physical changes occur, the surface is cleaned, and hydrocarbon contaminants such as oils and auxiliary additives are removed. Change the structure of molecular chains on the surface according to the composition of the material. The free radicals such as oxygen free radicals and hydroxyl groups were established to promote the adhesion of various coating materials, and were optimized in the application of adhesion and coatings. With the same effect, a very thin coating surface with high tension can be obtained by plasma surface treatment, without the need for any strong components such as other mechanical and chemical treatments to increase adhesion.


Many physical and chemical changes have taken place on the surface of the material sheet by means of plasma surface treatment, such as etching and roughening, forming a dense crosslinking layer, or introducing polar groups containing oxygen to improve hydrophilicity, adhesion, dyeability, biocompatibility and electrical properties, respectively. The surface morphology of the material is significantly changed by the treatment of the material surface under the appropriate process conditions, and the introduction of a variety of oxygen-containing groups makes the surface change from non-polar and difficult to adhere to a certain polarity, easy to adhere to and hydrophilic, which is conducive to bonding, coating and printing.
