What is float glass? What is the difference with ordinary glass?
Glass is an indispensable existence in modern life. There are many kinds of glass, including ordinary glass, art glass, tempered glass and so on. I wonder if you have heard of float glass? What is the difference between float glass and ordinary glass? Next, we will make a detailed introduction to float glass, hoping to help friends who need it in this regard.
1、 Both ordinary glass and float glass are flat glass. Only the production process and quality are different.
1. Ordinary glass is a transparent and colorless flat glass produced by using quartz sandstone powder, silica sand, potassium fossils, soda ash, mirabilite and other raw materials in a certain proportion, melting in a furnace at high temperature, and by vertical lead-up method, flat drawing method, calendering method. According to the appearance quality, ordinary flat glass is divided into three categories: special products, first-class products and second-class products. According to the thickness, it is divided into five types: 2, 3, 4, 5 and 6mm.
2. Float glass is a clean and colorless flat glass made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials in a certain proportion, which is melted at high temperature in the furnace, the liquid glass flows continuously from the tank furnace to the metal surface and floats on the metal surface, which is spread into a glass belt with uniform thickness and polished by fire, which is separated from the liquid metal after cooling and hardening, and then annealed and cut. The glass surface is particularly flat and smooth, the thickness is very uniform, and the optical distortion is very small. According to the appearance quality, float glass is divided into three categories: excellent products, first-class products and qualified products. According to the thickness, it is divided into nine types: 3, 4, 5, 6, 8, 10, 12, 15 and 19mm.
2、 The appearance quality grade of ordinary glass is determined according to the number of defects such as wavy bars, bubbles, scratches, sand particles, pimples, and lines. The appearance quality grade of float glass is judged according to the number of defects such as optical deformation, bubbles, inclusions, scratches, lines, fog spots, etc.
3、 Ordinary glass, emerald green, fragile, low transparency, easy to age and deform under rain and exposure. Float glass, transparent float glass is made of glass paste that enters the tin bath through the control gate, floats on the surface of molten tin due to gravity and its surface tension, and then enters the Xu cold bath, making both sides of the glass smooth and uniform, and the ripples disappear. Dark green, smooth surface without ripple, good perspective and certain toughness.
4、 The production process of float glass is different from that of ordinary glass. The advantage is that the surface is hard, smooth and flat. The color of float glass is different from that of ordinary glass from the side. It is white, and the object is not distorted after reflection, but generally has water texture deformation.
what are the uses of float glass?
Float glass is widely used, including tinted glass, float silver mirror, float glass / car windshield level, float glass / various deep processing levels, float glass / scanner level, float glass / coating level, float glass / mirror making level. Among them, ultra white float glass has a wide range of uses and broad market prospects. It is mainly used in high-end buildings, high-end glass processing and solar photovoltaic curtain walls, as well as high-end glass furniture, decorative glass, crystal like products, lamp glass, precision electronics industry, special buildings, etc.
