Plasma cleaning machine uses the ability of plasma to produce non-equilibrium electrons, reactive ions and free radicals at low temperature. High energy reactive groups in plasma bombard the surface, resulting in sputtering, thermal evaporation or photodegradation. The plasma cleaning machine uses the activation of various high energy substances in the plasma to completely peel off and remove the dirt adsorbed on the surface of the object. At present, plasma cleaning machine is mainly divided into two categories, one is atmospheric plasma cleaning machine, the other is vacuum plasma cleaning machine.
The air plasma cleaning machine is composed of plasma generator, gas pipeline, plasma nozzle and other components. The high-pressure and high-frequency energy produced by the plasma generator generates low-temperature plasma in the glow discharge activated and controlled in the nozzle steel tube. Plasma is ejected to the workpiece surface by compressed air. When the plasma meets the surface of the object to be treated, the object will undergo changes and chemical reactions. The surface has been cleaned, and there are hydrogen carbide pollutants, such as grease and auxiliary additives. Has been removed. These genes can promote adhesion of various coating materials and optimize adhesion and coating application. Under the same effect, very thin high-pressure coating surface can be obtained by plasma treatment, which is conducive to adhesion, coating and printing. There is no need for other strong acting parts such as mechanical and chemical treatment to increase adhesion.
Vacuum plasma cleaning machine is composed of vacuum generating system, electrical control system, plasma generator, vacuum chamber, machinery and other parts. The vacuum system and vacuum chamber can be customized according to the special requirements of customers. It is easy to adopt numerical control technology with high degree of automation. With high precision control device, the time control accuracy is very high; the correct plasma cleaning will not produce damage layer on the surface, ensuring the surface quality. Since cleaning is carried out in vacuum, it will not pollute the environment and the clean surface will not be polluted for the second time.
Vacuum plasma cleaning machine is a kind of material produced by gas molecules in special occasions such as vacuum and discharge. A plasma cleaning / etching device for generating plasma is arranged in a sealed container. It is widely used in plasma etching of surface degreasing and cleaning, etching of polytetrafluoroethylene (PTFE) and polytetrafluoroethylene mixture, surface activation and cleaning of plastics, glass and ceramics, plasma plating polymerization and other processes, so it is also used in high-precision fields such as automotive electronics, military electronics and printed circuit board manufacturing industries.
Vacuum plasma cleaning machine forms electromagnetic field through two electrodes, and uses vacuum pump to achieve a certain degree of vacuum. As the gas becomes thinner and thinner, the distance between molecules and the free movement distance of molecules or Guo become longer and longer. Under the action of magnetic field, the plasma is formed by collision. At the same time, glow will appear. The plasma moves in the electromagnetic field, bombards the surface of the object to be treated, removes oil and surface oxides, organic matters and other chemicals on the surface of the ash, so as to achieve the effect of surface treatment, cleaning and etching. The selective surface modification can be realized by plasma treatment.
The above is the difference between atmospheric vacuum plasma cleaning machine and vacuum plasma cleaning machine. I hope it will help you.
