Plasma cleaner "wash" what
Some people may ask since it is called a plasma cleaner, is not anything dirty can be washed away? In the end, what is washed? For this type of problem I believe that many people just contact plasma cleaner will think, so here we need to explain.
Plasma cleaner, also known as plasma machine, plasma surface treatment equipment. From the name alone, cleaning is not cleaning, but treatment and reaction. From the mechanism: plasma cleaner in the cleaning through the working gas in the electromagnetic field under the action of the excitation of the plasma and the surface of the object to produce a physical reaction and chemical reaction. Among them, the physical reaction mechanism is the active particles bombard the surface to be cleaned, so that the pollutants out of the surface and ultimately sucked away by the vacuum pump; chemical reaction mechanism is a variety of active particles and pollutants react to generate volatile substances, and then by the vacuum pump to suck away the volatile substances, so as to achieve the purpose of cleaning.
Our working gas, often used hydrogen (H2), nitrogen (N2), oxygen (O2), argon (Ar), methane (CF4) and so on. In the plasma cleaner process is easy to metals, semiconductors, oxides and most polymer materials, such as polypropylene, polyester, polyimide, polychloroethylene, epoxy, and even polytetrafluoroethylene. In this way we can easily associate: remove parts on the oil, remove the watch on the polishing cream, remove the circuit board on the glue residue, remove the water on the DVD and so on the extended field can be solved by plasma cleaner.
But, "wash the surface" is the core of the plasma cleaner technology, this core is now the reason why many companies choose three and Poda plasma cleaner focus." Wash the surface" and plasma machine and plasma surface treatment equipment, the two names are closely linked. Simply put, washing the surface is to make countless small holes on the surface of the treated material that cannot be seen by the naked eye, and at the same time forming a new oxide film on the surface. This greatly increases the surface area of the treated material, indirectly increasing the adhesion, compatibility, infiltration, diffusion, etc. of the material surface. And these properties and appropriate applications in cell phones, television, microelectronics, semiconductors, medical, aviation, automotive and other industries, for many companies to solve the problem of many years have not been solved.
So, the plasma cleaner is not what dirt can be washed away, it is more targeted removal of certain substances and materials surface modification treatment.
