Application of vacuum in coating industry
Vacuum coating technology is an important branch of vacuum technology, vacuum insulation board It has been widely used in optics, electronics, energy development, physical and chemical equipment, construction machinery, packaging, civil products, surface science and scientific research fields. The methods used in vacuum coating are mainly evaporation plating, sputtering plating, ion plating, beam deposition and molecular beam epitaxy. In addition, there are chemical vapor deposition methods. This technique is an important part of the vacuum surface treatment technology, if the purpose of the vacuum coating is to change the physical and chemical properties of the material surface. A brief introduction is made on several major applications.
First, in optics, a film of a glass or quartz surface coated with a layer or layers of different substances, a reflection or transmission material that can be a high reflection or no reflection (i.e. the penetration film) or any expected ratio, or a filter of a wavelength that is transmitted to another wavelength. The high reflective film begins with a large aperture telescope and a wide range of lasers, and it is necessary to be coated with jasmine, a large window of new buildings. The penetration film is used for photography and lasers, and a large window of glass coated with a new building is needed. The penetration film is used for cameras and television cameras. Vacuum coating is a very important position in electronics. The succession circuits of various sizes. including storage, operators, telling logic components and so on to use conductive film, insulation film and protective film.
