What are the principles and characteristics of plasma automatic cleaning machine?

  Plasma cleaning machine, also known as plasma cleaning machine and plasma surface treatment instrument, is a new high-tech technology that uses plasma to achieve effects that conventional cleaning methods cannot achieve. Plasma cleaning machine uses the properties of these active components to treat the sample surface, thereby achieving the purpose of cleaning and coating.

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 plasma cleaning machines used in China, including those imported from abroad, have control units mainly divided into four modes: semi-automatic control, fully automatic control, PC computer control, and LCD touch screen control.

The principle of plasma cleaning is mainly to rely on the "activation effect" of active particles in 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: inorganic gases are excited into plasma state; gas phase substances are adsorbed on the solid surface; adsorbed groups react with solid surface molecules to generate product molecules; product molecules are resolved to form gas phase; reaction residues are detached from the surface.

The characteristic of plasma cleaning technology is that it can process all substrate types regardless of the treatment object. It can process metals, semiconductors, oxides and most polymer materials, such as polypropylene, polyester, polyimide, polyvinyl chloride, epoxy, and even polytetrafluoroethylene, and can achieve overall and local cleaning as well as complex structure cleaning.
