What Are the Principles and Characteristics of Plasma Cleaner ?

As people have higher and higher requirements for quality of life, plasma surface treatment technology and processes are gradually valued by various industries; and Plasma Cleaner as the carrier of this emerging process, its structure, principle and application Research and discussion in other fields are very worth looking forward to!

Custom Plasma Cleaner, also known as plasma cleaner and plasma surface treatment instrument, is a brand new high-tech technology that uses plasma to achieve effects that conventional cleaning methods cannot. Plasma cleaners use the properties of these active components to treat the sample surface to achieve cleaning and coating purposes.

Custom Plasma Cleaner

The structure of the plasma cleaning machine is mainly divided into three major parts, namely the control unit, the vacuum chamber,

and the vacuum pump. The control unit of the plasma cleaning machine is mainly divided into four modes: semi-automatic control, fully automatic control, PC computer control, and LCD touch screen control.

The principle of plasma cleaning mainly relies on the "activation" of active particles in the plasma to achieve the purpose of removing stains on the surface of objects. In terms of reaction mechanism, plasma cleaning usually includes the following processes: the inorganic gas is excited into a plasma state; the gas phase material is adsorbed on the solid surface; the adsorbed group reacts with the solid surface molecule to generate product molecules; the product molecules decompose to form the gas phase; the reaction The residue is free from the surface. The principle of plasma cleaning is mainly:

(1) The etching effect on the surface of the material-a large amount of ions, excited molecules, free radicals and other active particles in the plasma that act on the surface of the solid sample, not only remove the original pollutants and impurities on the surface And it will cause etching, roughen the surface of the sample, and form many fine potholes, increasing the specific surface of the sample. Improve the wetting properties of solid surfaces.

(2) Activate the bond energy, the particle energy in the plasma of cross-linking is 0~20eV, and most of the bond energy in the polymer is 0~10eV, so after the plasma acts on the solid surface, the original Some chemical bonds are broken, and free radicals in the plasma form a network of cross-linked structures, greatly activating surface activity.

(3) Formation of new functional groups-chemical action If a reactive gas is introduced into the discharge gas, a complex chemical reaction will occur on the surface of the activated material, introducing new functional groups such as hydrocarbon groups, amino groups, carboxyl groups, etc. These functional groups are all Active groups that can significantly improve the surface activity of the material.

The biggest feature of plasma cleaning technology is that it can be processed regardless of the type of substrate to be processed. It can process metals, semiconductors, oxides, and most polymer materials such as polypropylene, polyester, polyimide, and polychloride. Ethane, epoxy, and even polytetrafluoroethylene can be handled well and can clean the whole and local and complex structures.
