[China Glass Network] What is ultra-white glass?
Ultra-clear glass is an ultra-transparent low-iron glass, also known as low-iron glass and high-transparent glass. It is a high-quality, multi-functional new high-grade glass variety with a light transmittance of over 91.5%. It has the characteristics of crystal clear, high-grade and elegant, and is known as the “crystal prince†of the glass family. Ultra-clear glass combines all the processing properties of high-quality float glass with superior physical, mechanical and optical properties, and can be processed in the same way as other high-quality float glass. Unparalleled superior quality and product performance give ultra-white glass a broad application space and bright market prospects.
Only the United States PPG, France Saint-Gobain, Britain's Pilkington, Japan's Asahi Glass, China Southern Glass, Taiwan Glass, Xinyi Group and other small enterprises master the production technology of ultra-white glass, high price and excellent quality, making ultra-white Glass became a symbol of building identity.
Advantages of ultra-clear glass
1. The self-explosion rate of glass is low. Because of the low content of NiS and other impurities generally contained in the ultra-white glass raw material, the fine control in the melting process of the raw material makes the ultra-white glass have a more uniform composition than the ordinary glass, and the internal impurities are less. Thereby greatly reducing the probability of self-explosion after tempering. 2. Color Consistency Since the iron content in the raw material is only 1/10 or less of that of ordinary glass, the ultra-white glass absorbs less in the green band of visible light than ordinary glass, ensuring the consistency of the color of the glass.
3. The visible light transmittance is high, the permeability is better than the visible light transmittance of 91.5%, and the crystal clear crystal quality makes the display more clear, and can highlight the original appearance of the exhibit.
4, low UV transmittance compared to ordinary glass, ultra-white glass absorption of the ultraviolet band is lower, used in places where UV protection, such as museums, can effectively reduce the passage of ultraviolet light, slow down the various exhibits in the showcase Fading and aging, especially for the protection of cultural relics.
5. The market is large, the technical content is high, and it has strong profitability. The ultra-white glass technology content is relatively high, the production control is difficult, and it has strong profitability relative to ordinary glass. The higher quality determines its high price. At present, the price of ultra-white glass is 1~2 times that of ordinary glass. The cost is not much higher than that of ordinary glass, but the technical barrier is relatively high and has a high added value.
How to distinguish ultra-white glass?
The simpler way is to look at the glass cut section: ordinary white glass has a darker green, blue or blue-green, while ultra-white glass has a very light blue.
How much is a square of ultra-white glass?
The price of ultra-white glass is what many people want to know. In fact, the price of ultra-white glass is more expensive than that of float glass, because ultra-white glass is a high-quality, multi-functional new high-grade glass that is currently on the market. The price of white glass is about 35% higher than that of ordinary glass. The price of ultra-white glass in each place is different. There are certain differences. Everyone should take the local standard. In addition, the price of ultra-white glass is still the same as the current one. The supply and demand situation, the distance of transportation, and the number of people who purchase it have a lot to do with it.
