Vacuum Coaters wet coating technology and coating technology

Vacuum Coaters wet coating technology and coating technology
Membrane extensive selection of vacuum coating technology, you can control the thickness of the film and coating system functionality and performance of different films, can make a lot of new material with chemical and physical properties.
Wet coating technology is way past a coating that plating or electroplating, chemical reduction of the principles applied in the material deposited, this method will produce waste polluting the environment, in the past a lot of plating plant because of pollution problems have changed the coating process .
Vacuum coating system film coating technology, the film less susceptible to contamination, in a vacuum environment can be improved purity and compactness, no waste without pollution. Vacuum coating itself is contaminated, but the actual vacuum system will be used in organic coatings, it will also cause pollution, but compared to the wet plating technique, a lot less pollution, high efficiency vacuum coating technology has strong vitality, but it does not mean that vacuum coating technology can completely replace the traditional wet coating technology, and in the thickness of the film, the anti-aging still take advantage of the wet coating method, vacuum coating thin film coating system.
In addition, a solid layer is affected by the process and adhesion, either wet or vacuum coating technology coating technology, if the material surface is not clean and will affect the binding layer material.
With the development of science and technology, vacuum coating technology industries has become a means of improving product quality, low cost vacuum coating significant economic benefits so that more and more companies eager, China's production of vacuum coating machine has reached a considerable level, the system can be plated vacuum coating materials are also more and more, but the foreign equipment and contrast a little gap also exists for the development of vacuum technology to be improved.

Historical Development of vacuum coating technology

Historical Development of vacuum coating technology
In the film prepared in vacuo, crystalline coating system comprising a metal, semiconductor, insulator and other elemental or compound film. Although the chemical vapor deposition also uses vacuum, low pressure or vacuum plasma and other means, but generally refers to a physical vacuum deposition method for depositing a thin film. Vacuum coating has three forms, namely vapor deposition, sputtering and ion plating.
Vacuum coating technology is now beginning in the 1930s, forties and fifties began industrial applications, industrial mass production began in the 1980s, has made a wide range of applications in the electronics, aerospace, packaging, decoration, gilt printing and other industries. Vacuum coating means in a vacuum environment, a metal or metal compound vapor is deposited onto the surface of the material in the form of (usually non-metallic material), is a physical vapor deposition process. Because often the metal film coating, it is also called vacuum metallization.
Generalized vacuum coating further comprises a metal or non-metallic materials and other non-metallic surface of the vacuum vapor deposition polymer functional film. In all plating material to the plastic is most common, followed by, for paper coating. Relative to metals, ceramics, wood and other materials, plastics have sufficient sources of performance is easy to control, easy processing and other advantages, so a wide variety of plastic or other polymer materials as structural engineering decorative materials, widely used in automobiles, household appliances, household packaging, decorative and other industrial fields. However, the presence of surface hardness of plastic materials are mostly not high enough to look gorgeous, abrasion and low defects, such as the plastic surface layer deposited thin metal film can be given away plastic bright metallic appearance, suitable metal source also can greatly increase the wear resistance of the material surface, greatly expanded the scope and application of decorative plastic.
