Refletive Glass: Coated glass is also called reflective glass.Coated glass is coated with one or more layers of metal, alloy or metal compound film on the glass surface to change the optical properties of the glass and meet certain specific requirements.Coating glass by the different characteristics of the product, can be divided into the following categories: heat reflection glass, Low radiation glass (low-e), conductive film glass.
Thermal reflection glass is generally plated on the glass surface with a layer or multiple layers such as chromium, titanium or stainless steel and other metals or their compounds composed of thin film, so that the product is rich in color, visible light has appropriate transmittance, infrared has a high reflectivity, for ultraviolet light has high absorption rate, therefore, also known as solar control glass, mainly used in buildings and glass curtain walls; Low emissivity glass is on the glass surface by multi-layer plating metals such as silver, copper or tin, or their compounds composed of membrane system, it has high transmittance of visible light, a high reflectivity of infrared ray, good heat insulation performance, mainly used in buildings and vehicles such as cars, ships, due to poor film strength, are usually made of hollow glass to use;Conductive film glass is coated with conductive film such as indium tin oxide on the glass surface.
There are many ways to produce coated glass, such as vacuum magnetron sputtering, vacuum evaporation, chemical vapor deposition and sol-gel.Magnetron sputtering coated glass can be designed and manufactured with multi-layer complex film system by magnetron sputtering technology, and can be plated with various colors on white glass substrates.Compared with magnetron sputtering coated glass, vacuum evaporation coated glass has been gradually replaced by vacuum sputtering.Chemical vapor deposition (CVD) is a process in which reaction gas is injected into the float glass production line and decomposed on the hot glass surface.The method is characterized by low input, easy control, low cost, good chemical stability and thermal processing, and is one of the most promising production methods at present.It is simple and stable to produce coated glass by sol-gel method.
*Solar control glass
On-line sunlight controlled coated glass is a kind of coated glass with good control effect on sunlight.The products have stable physical and chemical properties, and can be widely used in all kinds of buildings, lighting Windows, etc.
*High light transmittance low-e glass
It has high visible light transmittance, high solar energy transmittance and far infrared ray transmittance, so it has excellent daylighting, more solar heat radiation through glass, and excellent heat insulation performance. It is suitable for the high-permeability buildings in the cold areas of north China and some regions, highlighting the effect of natural lighting.
*Shading low-e glass
It has certain cover positive to indoor line of sight, can prevent solar heat radiation to enter indoor, the secondary heat radiation that limits summer outdoor enters indoor, south, north is applicable.Due to its rich decorative effect and outdoor shading effect, it is suitable for all kinds of buildings.
*Double-silver low-e glass
It highlights the shading effect of glass on solar thermal radiation, combines the high light transmittance of glass with the low solar thermal radiation transmittance, and has a high visible light transmittance, which can effectively limit the outdoor background thermal radiation into the indoor in summer
