[China Glass Network] 1. What is coated glass?

Coated glass is a film coated with one or more layers of metal, alloy, metal oxide or other substance on the surface of the glass, or migrates metal ions into the surface layer of the glass to change the optical properties of the glass to meet a specific Required glass processed products.

2. According to product characteristics, what types of coated glass are divided?

According to product characteristics, coated glass can be divided into solar control coated glass, low-emission coated glass, self-cleaning glass and transparent conductive film glass.

China's current national standard GB/T18915 "coated glass", the coated glass is divided into two categories, namely, solar control coated glass and low-emission coated glass. Sunlight control coated glass refers to glass that has a certain control effect on sunlight with wavelength range of 350-1800um. It has rich color change, excellent appearance decoration effect, good shading performance, and can keep indoor light soft and comfortable. The heat reflection capability can save indoor air conditioning energy. Low-emission coated glass, also known as low-emissivity glass or LOW-E glass, is a coated glass with a high reflectance to far-infrared rays with a wavelength range of 4.5 to 25 μm.

3. What is the solar control coated glass?

Sunlight-controlled coated glass, often referred to as coated glass, refers to a film coated with one or more layers of a metal such as chromium, titanium or stainless steel or a compound thereof on the surface of the glass to make it suitable for sunlight in the wavelength range of 350-1800 um. The control effect, that is, the suitable transmittance for visible light, the high reflectance to infrared rays, and the high absorption rate of ultraviolet light, also known as heat reflective film glass, mainly used in construction and glass curtain walls. field.

4. What is low-emission coated glass?

Low-emission coated glass (LOW-E glass) refers to a thin film system consisting of a plurality of layers of silver, copper or tin or a compound thereof, which is coated on the surface of the glass to have a high reflection of far infrared rays having a wavelength range of 4.5 to 25 um. Ratio, that is, high transmittance to visible light, high reflectivity to infrared rays, coated glass with good thermal insulation properties, mainly used in construction and transportation such as automobiles and ships.

5. What is self-cleaning glass?

Self-cleaning glass is a layer of semiconductor oxide nano-film deposited on the surface of float glass by CVD. The film has two properties after being exposed to ultraviolet light or sunlight: one is photocatalytic activity, which can adhere to the glass. The organic pollutants are degraded into carbon dioxide and water; the second is hydrophilic, that is, water droplets can spread into water film instead of water droplets. These two properties of self-cleaning glass enable the glass to have a self-cleaning function. First, the organic contaminants adhering to the surface of the self-cleaning glass decompose into carbon dioxide and water under the photocatalytic activity of the film layer; secondly, the dust attached to the surface of the glass The inorganic contaminants are washed away under the action of water or tap water to keep the glass surface clean.

6. What is a transparent conductive film glass?

The transparent conductive film glass refers to a coated glass which is uniformly plated with a transparent conductive oxide film by physical or chemical plating on the surface of the glass, and is called TCO glass.

TCO glass is mainly used in the fields of flat liquid crystal display (LCD), electroluminescence display (ELD), electrochromic display (ECD), transparent electrodes for solar cells, and transparent surface heaters for anti-fog and defrosting of vehicles, airplanes, etc. Its potential use can be extended to the manufacture of flexible light-emitting devices, plastic liquid crystal displays, collapsible solar cells, and as insulation materials for plastic greenhouses, glass paste films, and the like.
