How is glass made, raw material proportioning?
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, mainly because the material used in quartz sand is superior and the iron content is very low (usually under 3/10000)
There are many kinds of glass, different kinds, different uses, and different ingredients.
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.
