Ultra-white glass is a kind of super transparent low iron glass, also known as low iron glass, high transparent glass. It is a new type of high-grade glass with high quality and multi-function. Compared with ordinary glass, super white glass absorbs less green band in visible light, ensuring the consistency of glass color. With very high transmittance, transmittance can reach more than 91.5%, with crystal clear, high-grade elegant characteristics, can provide very good visual effects. Also known as the "Crystal Prince" of the glass family. Ultra white glass has all the machinable properties of high quality float glass, has superior physical, mechanical and optical properties, and can be processed as other high quality float glass. The incomparable superior quality and product performance make super white glass have broad application space and bright market prospects. The high price and excellent quality make the super white glass a symbol of the building's status.(1) Different iron content The main difference between the transparency of ordinary white glass and ultra-white glass is that the amount of iron oxide is different, the content of ordinary white is more, and the content of ultra-white is less. (2) Different light transmittance Because the iron content is different, the light transmittance is also different. The transmittance of general white glass is about 86%; Ultra-white glass is a kind of ultra-transparent low-iron glass, also known as low-iron glass and high-transparent glass. The transmittance can reach more than 91.5%. (3) The self-explosion rate of glass is different Because the ultra-white glass raw materials generally contain less impurities such as NiS, the fine control during the melting process of the raw materials makes the ultra-white glass have a more uniform composition than ordinary glass, and its internal impurities are less, which greatly reduces the possibility of self-explosion after tempering. (4) Different color consistency Since the iron content in the raw material is only 1/10 or lower than that of ordinary glass, the ultra-white glass absorbs less of the green band in visible light than ordinary glass, ensuring the consistency of the glass color.Picture comparison of ordinary glass and ultra-white glass：It is mainly used in the following aspects: 1. senior buildings inside and outside decoration (doors and Windows, partition, curtain wall, etc.): its unique high light transmittance makes the building with natural, transparent, avant-garde artistic effect, more in line with the modern design style. 2. display cabinet: can be used as a museum, exhibition view, jewelry store display window, let people feel the real color of the display. 3. greenhouse lighting canopy: can make the indoor get sufficient natural light lighting, but also has beautiful visual feelings. 4. High-grade glass furniture and crystal products: glass furniture made of super white glass is crystal clear, elegant and beautiful, giving people excellent visual effects. 5. Solar cell substrate: super white glass has high transmittance and low reflectivity to sunlight, which can be used as the substrate of photoelectric conversion system and the panel of photothermal conversion system. 6. the automobile industry with glass original: with super white glass to make car safety glass more beautiful and elegant.
