pvd coating machine has now become an indispensable part of life, adding a brilliance to life. Vacuum coating technology is an important branch of vacuum application technology. It has been widely used in optics, electronics, energy development, physical and chemical instruments. , construction machinery, packaging, civil products, surface science and scientific research and other fields. The methods used in vacuum coating mainly include ion plating, beam deposition plating, evaporation plating, sputtering plating, and molecular beam epitaxy. There is also chemical vapor deposition. If the purpose of vacuum coating is to change the physical and chemical properties of the material surface, this technology is an important part of vacuum surface treatment technology

 Vacuum coating occupies a very important position in electronics. Succession circuits of all sizes. Conductive film, insulating film and protective film should be used for memory, arithmetic unit, and telling logic elements. A chrome film is used as a mask for the fabrication of circuits. Magnetic tapes, magnetic disks, semiconductor lasers, Josephson devices, and charge-coupled devices (CCDs) also use various thin films.
In terms of display devices, video magnetic heads, high-density video tapes, transparent conductive films of flat-panel display devices, light guide films of camera tubes, and aluminum linings of fluorescent screens of display tubes are also prepared by vacuum coating. In terms of components, evaporating nickel-chromium, chromium or metal ceramics in vacuum can make resistors, evaporating aluminum, silicon monoxide, titanium dioxide, etc. on plastics can make capacitors, evaporating selenium can get toner cartridges for electrostatic copiers, evaporating barium titanate can make Manufacture of magnetostrictive sounding elements and more. Vacuum evaporation can also be used to fabricate superconducting films and microbead coatings for inertial confinement catastrophic reactions. In addition, it can also vapor-deposit decorative films on jewelry, watch case surfaces, textile metal patterns, gold and silver threads, etc., and use sputtering or ion plating to manufacture superhard films on tools and molds. In the past two years, multi-arc ion plating to prepare titanium products, such as stainless steel sheets, mirror panels, pillars, handrails, high-end bed brackets, stair railings, etc., is currently prevalent.
The pvd coating machine has excellent touch function and high bonding force on the coating and the coating layer. The thermal expansion coefficient of the pvd coating machine has a small difference, no response, and good leveling function.
pvd coating machine has excellent vacuum function. After the primer layer is cured, the outgassing amount is small, the thermal stress is small, and the heat resistance function is good. The pvd coating machine has good film forming performance, and the coating density, covering ability, solvent resistance and light resistance are excellent. The vacuum coater has excellent compatibility with the top coat. Because the coating layer is very thin and porous, the solvents and thinners of the base coat and top coat are required to have good compatibility.
pvd coating machine has excellent application performance. Excellent leveling performance, proper viscosity and short curing time. The pvd coating machine and the coating layer must have excellent touch function, and must have a certain compatibility with the primer layer; excellent film-forming function and application function; appropriate mechanical strength; moisture-proof, solvent-resistant, and corrosion-resistant. Strong anti-aging function.
