Heat-reflective glass is usually coated with one or more layers of glass or metal such as chromium, titanium or stainless steel or its compound film, the product was rich in color, the visible light has a suitable transmittance, a higher infrared Reflectivity, high absorption rate of ultraviolet light, therefore, also known as the sun control glass, mainly used in construction and glass curtain wall; low-emissivity glass is plated on the glass surface by the multi-layer silver, copper or tin and other metals or their compounds Of the film system, the product has a higher transmittance of visible light, a high infrared reflectivity, has good thermal insulation properties, mainly used in construction and automobiles, ships and other transport, due to poor film strength, the general Are made of hollow glass use; Conductive film glass is coated with conductive film such as indium tin oxide glass, glass can be used for heating, defrosting, defogging and as a liquid crystal display.
Coated glass production methods, there are vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol-gel method. Magnetron Sputtering Coated Glass Magnetron Sputtering technology allows the design and manufacture of multi-layer complex film systems with a wide range of colors available on white glass substrates with good corrosion and abrasion resistance. One of the most used products. Vacuum evaporation of coated glass varieties and quality compared with magnetron sputtering coated glass there is a certain gap, has been gradually replaced by vacuum sputtering method. Chemical vapor deposition method is in the float glass production line through the reaction gas decomposition in the hot glass surface, uniformly deposited on the glass surface to form coated glass. The method is characterized by less equipment investment, easy regulation, low product cost, good chemical stability, thermal processing, and is currently one of the most promising production methods. Sol-gel production of coated glass process is simple, the stability is good, the downside is the product of light transmittance is too high, poor decorative.
