Analysis of the difference between float glass and ultra white glass
Float glass is made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials, melting through the melting furnace, glass from the kiln continuous flow to and floating on the metal surface, the thickness of uniform formation, Polished glass ribbon, cooled hardened from the metal liquid, and then cut by cutting the transparent colorless flat glass. The forming process of the float process is carried out in the tin bath into the protective gas.
Ultra-white glass is a super-transparent low-iron glass, also known as low iron glass, high transparent glass. It is a high-quality, multi-functional new high-grade glass varieties, light transmission rate of up to 91.5%, with crystal clear, high-grade elegant features, a glass family "Crystal Prince," said.
The difference between float glass and ultra white glass:
Float colorless glass with float Ultra white glass From the appearance point of view, the biggest difference is transparency. The former is not strictly required, usually visible light transmission ratio of 89% (3mm), while the ultra-white is a strict requirement, but also to cause the glass color (blue, green) iron oxide content is also strictly defined: visible light transmission ratio is not low In the 91.5% (3mm), iron oxide (Fe2O3) content of not more than 0.015% (ordinary float is about 0.1%, 10 times higher).
