Ordinary Flat Glass And Float Glass Has Different?

A: ordinary flat glass and float glass is flat glass. But in a different production process, quality.

Ordinary flat glass is made of quartz sandstone powder, silica sand, soda ash, sodium sulfate, potassium fossil raw materials, according to the certain proportion, high temperature melt furnace, by vertical drawing method, or method, calendered transparent flat glass produced. Appearance quality is divided into ordinary flat glass by preference, first grade, second grade three class. According to the nominal thickness can be divided into 2, 3, 4, 5, 6, 8, 10, 12, 15, 19, 22, 25mm total 12 kinds of specifications. (See GB11614-2009 in the flat glass)

B: floating method glass is with sea sand, and quartz sandstone powder, and soda, and dolomite, raw materials, by must proportion preparation, by melt kiln high temperature melting, glass liquid from pool kiln continuous flow to and floating in metal liquid surface Shang, assessment into thickness uniform flat, and by fire polishing of glass with, cooling hardening Hou from metal liquid, again by annealing cutting and into of transparent colorless flat glass. Special smooth, uniform thickness of the glass surface, characteristic of optical distortion is very small. Float glass quality is divided into grade, level, qualified product categories. According to the thickness of 3, 4, 5, 6, 8, 10, 12, 15, 19mm nine.

C: ordinary flat glass appearance quality grade is based on a cord, bubbles, scratches, sand grain, knots, road defects, such as judging. Appearance quality grade is based on optical deformation of float glass, bubbles, inclusions, scratches, lines, fog spot defects and how many convicted.

D: ordinary glass, Emerald, brittle, opaque, aging deformation under rain and Sun.

Float glass, transparent glass is float glass paste through the control gate into tin bath, because the force of gravity and surface tension effects after floating on the molten Tin surface, then go for Xu tank, glass smooth both sides, made ripples disappear. Dark green, smooth surfaces without ripples, good perspective, has a certain toughness.
