Introduction of Vacuum Coating Technology Classification
The professionalism of vacuum coating is the application of physical analysis and chemical methods to coat the solid surface with a unique surface coating, so that the solid surface has abrasion resistance, high temperature resistance, corrosion resistance, oxidation resistance, electromagnetic wave radiation, and conductivity. , Magnetism, cable sheathing and design and decoration are superior to the advantages of solid raw materials themselves, which can improve product quality, increase product service life, save energy, and obtain significant professional economic benefits. Therefore, the professionalism of vacuum coating is known as one of the most important professions with the most development prospects, and it shows attractive prospects for the development of the industry in the development trend of the high-tech industry development plan. This powerful vacuum coating expertise has been applied to various fields of social and economic development, such as international airlines, aerospace airlines, electronic components, information, industrial equipment, petroleum, chemical companies, ecological environmental protection, defense and security and other manufacturing industries.
Vacuum coating technology is generally divided into physical liquid phase deposition (PVD) technology and organic chemical liquid phase deposition (organic chemical liquid phase deposition) technology. Physics liquid-phase accumulation technology refers to the method of using various physical methods to convert electroplating materials' volatile molecules, molecular structures or weak electrolytes into positive ions under vacuum pump standards, and immediately accumulate them on the basic surface. Hard reflective film is mainly based on the accumulation of physics liquids. The whole process of physics such as the thermal volatilization of chemical substances and the magnetron sputtering of ion bombardment molecules on the surface of the chemical substance is used to complete the entire process of controlled transfer of chemical substance molecules from the source chemical substance to the plastic film. Physics liquid-phase accumulation technology has good film/substrate bonding, uniform plastic film with uniform high density, good controllability of plastic film thickness, wide application targets, wide magnetron sputtering coverage, thick plastic film accumulation, aluminum alloy The plastic film has the advantages of stability and good repeatability. The organic chemical liquid-phase stacking technology is a way to display the elemental vapor and chemical substances of the plastic film on the basis, and make the metal material and chemical substance plastic film on the basis according to the liquid phase effect and the chemical change of the basic surface layer.
Vacuum coating can make raw materials have many new and high-quality physical and analytical chemical characteristics. In the 1970s, the methods of coating the surface of objects mainly included electroplating and electroless nickel plating. The former is based on the plug-in wire, and the plasma of the lithium battery electrolyte electrolysis salt water and electrolysis salt water is smeared on the basic surface of the other electrode. Therefore, the surface coating specification of this surface is basically a good conductor of electricity and a plastic film. The thickness is also uncontrollable. The latter adopts the analytical chemical reduction method, try to configure the thin film material into a solution, and can apply for the oxidation-reduction reaction immediately. This surface coating method not only has poor combined tensile strength of the plastic film, but also has uneven surface coating that is difficult to control. It also continues to have a lot of sewage, causing serious air pollution. Therefore, these two surface-layer electroplating techniques, which are called wet surfaces, are subject to great restrictions.
