Glass factory raw materials specific to do?
Glass is formed by melting sand with other chemicals (the main ingredients are: soda ash, limestone, quartz). A continuous network structure is formed during melting, and the silicate like non-metallic material is gradually increased and hardened in the process of cooling. The chemical composition of ordinary glass is Na2O, CaO, 6SiO2, the main component is silica, is a kind of amorphous structure with irregular structure. Widely used in buildings for wind and light transmission; of mixtures. There is also colored glass mixed with certain metal oxides or salts, and toughened glass made by special methods. Sometimes some transparent plastic (such as polymethyl methacrylate) is also called organic glass.
The glass factory is to produce glass raw materials of dolomite, sandstone, soda ash, mirabilite and so on materials in proportion to reconcile into a block by mechanical device to melt kiln.
The glass is the main component in the manufacturing process of quartz sand, quartz sand is combined with other chemical materials at high temperature (1300 degrees Celsius) crystallized after firing the cooling of the body, with a hard, abrasion resistance, corrosion resistance and high transmittance characteristics, its wide application has a long history. The manufacturing technology of the use of glass a thousand li a day, increasing by the clock, glass, doors and windows, lamps, such as high-tech electronic components and space technology, are indispensable glass. Our daily contact with most of the "flat glass is" thick to thin for doors and windows, clocks and the use of medical tests, the manufacturing method is that the furnace in the glass slurry level or traction method (also called float) and vertical traction method. After the dissolution of soluble traction after furnace also has the cooling system, cooling after the completion into a "flat glass, flat glass thickness mainly depends on the speed of traction, traction faster, can be manufactured and thinner. Although the ordinary flat glass from the front appears bright transparent, but from the side near the edge is slightly blue, because the amount of glass color depends on the main raw material in the manufacture of glass - quartz sand and iron content of purity. Generally, the thin glass used in the watch industry is superior in quality but expensive in value. The main difference is that the raw material used in the quartz sand is superior and the iron content is very low (usually under 3/10000)
