A: Ordinary flat glass and float glass are flat glass. It's just different in production technology and quality. Ordinary flat glass is a kind of transparent and colorless flat glass made of quartz sandstone powder, silica sand, potassium fossil, soda ash, mirabilite and other raw materials in a certain proportion, which is melted in a furnace at high temperature, and produced by vertical drawing method, horizontal drawing method and calendering method. According to the appearance quality, ordinary flat glass can be divided into three categories: special selection, first-class and second-class. According to the thickness, it can be divided into 5 types: 2, 3, 4, 5 and 6 mm.
B: Float glass is a kind of transparent and colorless flat glass, which is made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials according to a certain proportion. After high temperature melting in the furnace, the liquid glass continuously flows from the tank to the metal surface and floats on the metal surface. It is spread into a glass belt with uniform thickness and polished by fire. After cooling and hardening, it is separated from the liquid metal, and then annealed and cut. The surface of the glass is very smooth, the thickness is very uniform, and the optical distortion is very small. According to the appearance quality, float glass can be divided into three categories: superior product, first-class product and qualified product. According to the thickness, it can be divided into 9 types: 3, 4, 5, 6, 8, 10, 12, 15 and 19mm.
C: The appearance quality grade of ordinary flat glass is determined according to the number of defects such as corrugated 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 and fog spots.
D: Ordinary glass, emerald green, fragile, low transparency, easy aging and deformation under rain and sun exposure. Float glass, transparent float glass is glass paste through the control gate into the tin bath, due to gravity and its own surface tension floating on the surface of molten tin, and then into the slow cooling bath, so that both sides of the glass smooth and uniform, ripple disappeared and made. Dark green, smooth surface, no ripple, good perspective, with a certain toughness.
E: Float glass and ordinary glass production process is different, the advantage is that the surface is hard, smooth, flat, float glass side view color is different from the general glass, white, reflective object does not distort, and the general water grain type deformation.
