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, there is UV
High absorption rate, therefore, also known as solar control glass, mainly used in construction and glass curtain wall; low-emissivity glass is a thin film system composed of multi-layer silver, copper or tin and other metals or their compounds on the glass surface, Visible light has a higher transmittance, a high reflectivity of infrared, has good thermal insulation properties, mainly used in construction and vehicles, ships and other transport, due to poor film strength, are generally made of insulating glass ; Conductive film glass is coated on the glass surface conductive film such as indium tin oxide can be used for glass 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 enables the design and manufacture of multi-layer complex film systems that can be coated with a wide range of colors on white glass substrates with good corrosion and abrasion resistance and is manufactured and used One of the most 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, is 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.read more:
