pvd coating machine coating glass is to coat one or more layers of metal, alloy or metal compound thin films on the glass surface to change the optical properties of the glass to meet certain specific requirements. Coated glass can be divided into the following categories according to the different characteristics of the product: heat reflective glass, low-emissivity glass (Low-E), conductive film glass, etc.

Heat reflective glass is generally coated with one or more layers of thin films composed of metals such as chromium, titanium or stainless steel or their compounds on the surface of the glass, so that the product is rich in color, has appropriate transmittance for visible light, and has a high degree of infrared radiation. Reflectivity, has a high absorption rate for ultraviolet rays, so it is also called solar control glass, which is mainly used in buildings and glass curtain walls;
Low-emissivity glass is a thin-film product composed of multiple layers of silver, copper, tin and other metals or their compounds coated on the glass surface. It has high transmittance to visible light, high reflectivity to infrared rays, and good heat insulation performance. , mainly used in construction, automobiles, ships and other means of transportation. Due to the poor strength of the film layer, it is generally used as insulating glass;
Conductive film glass is coated with conductive film such as indium tin oxide on the glass surface, which can be used for heating, defrosting, defogging and liquid crystal display of glass.
There are many production methods for pvd coating machine coated glass, mainly vacuum magnetron sputtering method, vacuum evaporation method, chemical vapor deposition method and sol-gel method.
Magnetron sputtering pvd coating machine coating glass can design and manufacture multi-layer complex film system by using magnetron sputtering technology, and can plate a variety of colors on the white glass substrate. The corrosion resistance and wear resistance of the film layer are good. One of the most produced and used products at present. There is a certain gap between the variety and quality of the pvd coating machine evaporation coating glass and the magnetron sputtering coating machine coating glass, which has been gradually replaced by the vacuum sputtering method. The chemical vapor deposition method is to pass the reaction gas into the float glass production line to decompose on the hot glass surface, and evenly deposit on the glass surface to form a coated glass. The method is characterized by less investment in equipment, easy regulation, low product cost, good chemical stability, and thermal processing. It is one of the most promising production methods at present. The process of producing coated glass by sol-gel method is simple and stable, but the disadvantage is that the light transmittance of the product is too high and the decoration is poor. The most widely used coated glass is heat reflective glass and low-emissivity glass. Basically, vacuum magnetron sputtering and chemical vapor deposition are two production methods.
