Plasma and material interaction of rotary bottle plasma cleaning equipment:
Rotating bottle plasma cleaning equipment often uses different process gases in practical applications. The generated plasma contains a large number of active particles and high-energy particles. The interaction between these particles and the surface of solid materials is of great significance to the plasma itself or solid materials.


The particles in the rotary bottle plasma cleaning equipment transfer energy to the surface of the solid material, while the plasma carries away large amounts of impurities. For solid materials, due to the bombardment and energy transfer of these high-energy particles, a variety of physical and chemical reactions take place on the surface of solid materials. Therefore, the study of the interaction process between plasma and the surface of solid materials is very beneficial to the exploration of material surface modification, new materials and new technologies.


Bottles of plasma cleaning equipment and all kinds of solid materials on the surface of the effect depends on the physical parameters of plasma, the kinds of solid materials, surface structure and morphology of factors, but plasma and effect on the surface of the solid material in the surface layer of only a few to dozens of nanometer (nm depth), so as not to damage the intrinsic characteristics of matrix; It can also make the material surface have new practicality.


Adsorption and desorption of plasma are very important, and in many cases one or the other often determines the mass of the surface. Adsorption results from the attraction between the incident body and the surface. There are two kinds of adsorption: physical adsorption produced in the weak interaction between molecules and the surface, physical adsorption is exothermic, physical adsorption and surface binding energy is very weak, can quickly spread from the surface after adsorption; When the adsorption atoms or molecules and surface atoms form chemical bonds, that is, the formation of chemical adsorption, this process is called the strong exothermic process.
