What are the principles of extended plasma cleaning equipment and innovative cleaning technologies

What are the principles of extended plasma cleaning equipment and innovative cleaning technologies:
The extended plasma cleaning equipment uses gas as the cleaning medium, which can effectively avoid secondary pollution caused by the liquid cleaning medium to the object to be cleaned. The plasma cleaning machine is connected to a vacuum pump, and the plasma in the cleaning chamber will slightly wash the surface of the object to be cleaned during operation. The short-term cleaning can make the contaminants be sucked away by the vacuum pump, and the cleaning degree reaches the molecular level. In addition to the super-cleaning function, the extended plasma cleaning equipment can also change the surface properties of certain materials under special conditions. For example, plasma has an effect on the surface of the material to recombine the chemical bonds of surface molecules to form new surface characteristics. For some special-purpose materials, the extended glow discharge in the super-cleaning process can not only enhance its adhesion, compatibility and wettability, but also disinfect. Extended plasma cleaning equipment has a wide range of applications in the fields of optics, optoelectronics, electronics, materials, life sciences, polymer sciences, biomedicine, and microfluidics.

Extended plasma cleaning equipment refers to the generation of gas molecules in special environments such as vacuum and electric discharge. The plasma generation equipment is to set two electrodes in a sealed container to form an electromagnetic field, and a vacuum pump is used to generate a certain degree of vacuum. As the gas becomes thinner and thinner, the distance between molecules becomes longer and longer, and the molecules or ions are free The moving distance is getting larger and larger. Under the influence of the magnetic field, it collides to form plasma and glows at the same time. The plasma moves on the electromagnetic field and bombards the surface of the object to be processed, so as to achieve the effects of surface treatment, cleaning and etching.
The plasma technology of the extended plasma cleaning equipment:
The use of plasma cleaning technology to remove organic contaminants on the surface of metals, ceramics, and plastics can significantly enhance their bonding performance and welding strength. The separation process can be easily controlled and repeated safely. If effective surface treatment is critical to product reliability or process efficiency, plasma technology is ideal.
Plasma technology can improve the performance of most materials through surface activation, etching and surface deposition: cleanliness, hydrophilicity, water resistance, adhesion, scale, lubricity, and wear resistance.
Cleaning principles and innovations of extended plasma cleaning equipment:
Apply a radio frequency voltage (frequency of about tens of megahertz) to a group of electrodes to form a high-frequency alternating electric field between the electrodes. Under the stimulation of the alternating electric field, the gas in the area will form plasma, and the active plasma will The object to be cleaned produces physical bombardment, and at the same time it also produces a chemical reaction, which converts the surface material of the object to be cleaned into particles and gas, which are exhausted by vacuuming, so as to achieve the purpose of cleaning.
In fact, in the entire production process, the key control elements of the plasma cleaning system include processing temperature, radio frequency power, gas distribution, vacuum, electrode settings, electrostatic protection, etc. The control system and these interactive parameters are critical to system performance.
The extended plasma cleaning equipment has been used in the manufacture of various electronic components. It is certain that without the plasma cleaning machine and its cleaning technology, there would be no such advanced electronics, information and communication industries as today. In addition, the plasma cleaner and its cleaning technology are also used in optics, machinery and aerospace, polymer, pollution prevention and measurement industries, it is the key technology for product upgrades, such as the coating of optical components, extending the life of molds or processing tools The wear-resistant layer, the intermediate layer of composite materials, the surface treatment of woven fabrics or contact lenses, the manufacture of micro-sensors, the processing technology of ultra-micromachines, the anti-wear layer of artificial joints, bones or heart valves, etc., all require plasma technology Development can be completed.
