Background technology
Along with the raising of expanding economy and people's living standard, society has higher requirement to the industry-by-industry of industry, and wherein for silicate industry, the plated film standard of glass is also thereupon more and more higher.The different qualities of product pressed by coated glass, can be divided into following a few class: heat-reflecting glass, low emissivity glass, electropane etc.Heat-reflecting glass is generally the film plating the metals such as one or more layers such as chromium, titanium or stainless steel or its compound composition at glass surface, product is made to be abundant color, suitable transmissivity is had for visible ray, higher reflectivity is had to infrared rays, higher absorption rate is had to ultraviolet, therefore, also referred to as solar-control glazing, be mainly used in building and glass curtain wall; Low emissivity glass is the film be made up of the metals such as silver, copper or tin or its compound in glass surface plating, product has higher transmissivity to visible ray, very high reflectivity is had to infrared rays, there is good thermal and insulating performance, be mainly used in building and the vehicles such as automobile, boats and ships, because film strength is poor, generally all make double glazing and use; Electropane is at conductive films such as glass surface coating tin indium oxides, can be used for the heating of glass, defrosting, demist and is used as liquid crystal display etc.
The production method of coated glass is a lot, mainly contains ion sputtering process, vacuum vapor deposition method, chemical Vapor deposition process and sol-gel method etc.Sputter-coated glasses utilizes sputtering technology can manufacture and design the complicated film system of multilayer, and can plate out multiple color on the glass substrate of white, the corrosion-resistant and wear resisting property of rete is better, is produce and use one of maximum product at present.All there is certain gap with quality in the kind of vacuum evaporation coating film glass, progressively sputtered method replaces compared with sputter-coated glasses.Chemical Vapor deposition process on floatation glass production line, passes into reactant gases decompose at scorching hot glass surface, is deposited on glass surface equably and forms coated glass.The feature of the method is that equipment investment is few, easy-regulating, and product cost is low, chemical stability good, can carry out hot-work, is one of the most rising current production method.Sol-gel method produces coated glass technique simply, and stability, weak point is that product optical transmittance is too high, ornamental poor.
