Classification Of Coated Glass

- Apr 19, 2018 -

Heat-reflecting glass is generally coated on the glass surface with one or more layers of metal such as chromium, titanium, or stainless steel or a compound thereof, so that the product is rich in color, has suitable transmittance for visible light, and has higher infrared ray Reflectivity, which has a high absorption rate for ultraviolet rays, is also referred to as solar control glass and is mainly used for architectural and glass curtain walls; low emissivity glass is composed of layers of silver, copper, tin, or other metals or their compounds The thin film system has high transmittance for visible light, high reflectivity for infrared ray, and good thermal insulation performance. It is mainly used in construction and vehicles such as automobiles and ships. Due to poor film strength, it is generally All are made of 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 of glass, and used as a liquid crystal display.

There are many methods for producing coated glass, including vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition, and sol-gel methods. Magnetron sputter coated glass can be used to design and fabricate multi-layered complex film systems using magnetron sputtering technology. It can be used to coat a variety of colors on white glass substrates. The film's corrosion resistance and wear resistance are better. It is currently produced and One of the most used products. There is a certain gap between the variety and quality of vacuum evaporation coating glass and magnetron sputtering coating glass, which has been gradually replaced by vacuum sputtering. Chemical Vapor Deposition is the introduction of a reactive gas on a float glass production line to decompose on a hot glass surface and uniformly deposit on the glass surface to form a coated glass. The method is characterized by low investment in equipment, easy control, low product cost, good chemical stability, and thermal processing. It is currently one of the most promising production methods. The sol-gel process for producing coated glass is simple and has good stability. The disadvantages are that the light transmittance of the product is too high and the decorative properties are poor.
