  What is the difference between ordinary flat glass and float glass?

  A: ordinary flat glass and float glass are flat glass. Only the production process, quality is different.

  Ordinary flat glass is used quartz sandstone powder, silica sand, potassium fossils, soda ash, Glauber's salt and other raw materials, according to a certain proportion, by melting furnace high-temperature melting, through the vertical method or flat pull method, calendering process produced by transparent colorless flat glass. Ordinary flat glass According to the appearance of quality is divided into special products, a class of products, two products three categories. According to the thickness of 2, 3, 4, 5, 6mm five species.

  B: Float glass is the use of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials, according to a certain proportion, through melting furnace high-temperature melting, glass liquid from the pool kiln continuous flow to and floating on the metal liquid surface, spread into a uniform thickness, through the fire polished glass belt, cooled after hardening from the metal liquid, and then by annealing cut into transparent and colorless flat glass. The glass surface is particularly smooth, the thickness is very uniform, the optical distortion is very small characteristics. Float glass According to the appearance of quality is divided into excellent products, first-class products, qualified products three categories. The thickness is divided into 3, 4, 5, 6, 8, 10, 12, 15, 19mm nine.

  C: ordinary flat glass appearance quality grade is based on the wave rib, bubble, scratches, sand grains, bumps, lines and other defects to determine how many. Float glass appearance quality grade is based on optical deformation, bubble, inclusions, scratches, lines, fog spots and other defects to be judged.

  D: Ordinary glass, emerald green, fragile, transparency is not high, rain exposure under the aging deformation

  Float glass, transparent float glass is the glass paste through the control gate into the tin trough, because of gravity and its own surface tension effect floating on the surface of molten tin, and then into the Xu Leng groove, so that the two sides of the glass smooth and uniform, the ripple disappears and made. Dark green, smooth surface without ripple, good perspective, with a certain toughness.

  E: Float glass and ordinary glass production process is different, the advantage is the surface is hard, smooth, flat, float glass side look at the color and the general glass different, white, reflective after the object is not distorted, and the general has a watermark type of deformation.
