Vacuum coating technology of water ring vacuum pump

The vacuum coating of water ring vacuum pump is a kind of technology to produce film material by physical way. This technology can protect the vacuum pump equipment and reduce its damage. However, many people may not understand this, so the following small series to give you a detailed introduction of the product's vacuum coating technology.

Vacuum coating technology is separated from the heating source to the surface of the pump, so it is also an important branch of water ring vacuum pump 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 main methods of vacuum deposition are evaporation, sputtering, ion plating, beam stacking and molecular beam epitaxy. In addition, there are chemical vapor deposition methods.

If the purpose of vacuum coating is to change the physical and chemical properties of the surface of water ring vacuum pump, this technology is an important part of the surface treatment technology of water ring vacuum pump. This paper introduces its main application. In terms of optics, a piece of optical glass or quartz coated with one or several layers of thin films of different substances can become highly reflective or non reflective (i.e., antireflective film) or any expected proportion of reflection or transmission data, and can also be used as a filter for absorbing certain wavelengths and transmitting for another wavelength.

The high reflective film of water ring vacuum pump is in great demand, starting from large aperture astronomical telescopes and various lasers, to large window coated jasmine of new buildings. Antireflective coatings are widely used in photography, laser start, and large window coated glass of new buildings. Antireflective coatings are widely used in cameras and television cameras. Vacuum coating plays an important role in electronics. Various ranges of inherited circuits. The conductive film, insulating film and maintenance film should be used for memory, arithmetic unit and notification logic element. As a mask for the preparation of the circuit, chromium film is used.
