Float glass: This is the general civilian flat glass because the production process is named after the glass floats on the surface of the tin solution. It is emphasized that the "float method" is aimed at the old production process, because now all the big manufacturers use the float method for flat panel production, and now there is no emphasis on significance. If someone emphasizes it, it must be JS misleading you.
Ultra-white glass: also known as colorless glass, high transparent glass, low-iron glass, is the most high-grade glass product, with high transmittance, high transparency, crystal clear, noble and elegant, there is a glass family "Crystal Prince "It is called. The light transmission rate determines the quality of the glass, the light transmittance of the float glass is 86%, and the transmittance of the ultra-white glass can reach more than 92%. It is mainly used in interior and exterior decoration of high-grade buildings, electronic products, high-grade car glass, and solar cells. , high-end horticultural architecture, high-grade glass furniture, various crystal products and other industries.
Floatless colorless glass and floated ultra-white glass In terms of appearance, the biggest difference is transparency. The former does not have strict requirements, usually visible light transmittance is 89% (3mm), and ultra-white has strict requirements, and also has strict regulations on the iron oxide content that causes the glass to be colored (blue and green): the visible light transmittance is not low At 91.5% (3mm), the content of iron oxide (Fe2O3) is not higher than 0.015% (ordinary float is about 0.1%, which is 10 times higher).
The development and application of solar energy will also be the development of ultra-white glass. * The huge business opportunity – Ultra-white glass is required for the glass substrate of solar photovoltaic power generation systems, because the transmittance of ultra-white glass is above 92%. Ultra-white glass has high technological content, it is difficult to produce, and it has strong profitability. Higher quality determines its expensive price, ultra-white glass is 4 to 5 times the price of ordinary glass (* analysis can even be up to 6 to 10 times), the cost is only 2 to 3 times that of ordinary glass, with high The added value. At present, only a few companies in the world, such as the United States PPG, Saint-Gobain in France, Pilkington in the United Kingdom, and Asahi Glass, have mastered the production technology of ultra-white glass, among which PPG has the most mature technology.
