Coated glass（Reflective glass）Also known as reflective glass。Coated glass is a type of glass that is coated with one or more layers of metal on its surface、Alloy or metal compound thin film，To change the optical properties of glass，Meet a specific requirement。Coated glass according to different characteristics of the product，It can be divided into the following categories：Heat reflective glass、Low radiation glass（Low-E）、Conductive film glass, etc。

Heat reflective glass is generally coated with one or more layers such as chromium on the surface of the glass、Metals such as titanium or stainless steel, or
A thin film composed of its compounds，Make the product appear in rich colors，Appropriate transmittance for visible light，Has a high reflectivity towards infrared radiation，Regarding ultraviolet radiation Coated glass has a higher absorption rate，therefore，Also known as sunlight control glass，Mainly used for construction andGlass Curtain Wall；Low radiation glass is coated with multiple layers of silver on the surface of the glass、Thin film systems composed of metals such as copper or tin or their compounds，The product has a high transmittance to visible light，Has high reflectivity for infrared radiation，Has good thermal insulation performance，Mainly used for construction and automobiles、Ships and other transportation vehicles，Due to poor membrane strength，Usually madeinsulating glassuse；Conductive film glass is a type of glass surface coated with conductive thin films such as indium tin oxide，Can be used for heating glass、defrost、Defogging and use asLCD display screenclass；

There are many production methods for coated glass，There are mainly vacuum magnetron sputtering methods、Vacuum evaporation method、Chemical vapor deposition method and sol—Gel method, etc。Magnetron sputtering coated glass can be designed and manufactured with multi-layer complex film systems using magnetron sputtering technology，Multiple colors can be plated on a white glass substrate，The corrosion resistance and wear resistance of the film layer are good，It is currently one of the most produced and used products。There is a certain gap in the variety and quality of vacuum evaporation coated glass compared to magnetron sputtering coated glass，It has gradually been replaced by vacuum sputtering method。Chemical vapor deposition method is used inFloat glassThe reaction gas introduced into the production line decomposes on the scorching glass surface，Uniformly deposit on the surface of glass to form coated glass。The characteristic of this method is that it requires less equipment investment、Easy to regulate，Low product cost、good chemical stability，Can be subjected to hot processing，It is currently one of the most promising production methods。sol—Production of coated glass by gel process is simple，Stability is also good，The drawback is that the light transmittance of the product is too high，Poor decorative quality。
