The main raw materials of flat glass are: silica sand (sandstone), sodium carbonate, feldspar, dolomite, limestone and mirabilite.
Technological process:1, raw materials broken: the above raw materials broken into powder;2, weighing: according to the list of ingredients, called a certain amount of powder;3, will be called: the mixed powder mixing, stirring into a batch (colored glass and colorant);4, melting: the mixture into the glass furnace, melting at 1700 degrees into glass;5, forming: the glass liquid into a tin bath (float), pull machine (lattice method), rolling machine (rolling method, adding metal wire is wire glass), forming the flat glass;6, annealing: the molding of glass products into the annealing furnace annealing, balance the stress, to prevent self cracking.
Ordinary glass plate glass, wire glass and quartz glass (also known as crystal glass) a molding. Wired glass as the quartz glass; only a raw material of sandstone or silica or quartz sand.Tempered glass is made of flat glass as raw material for re processing: the cut of the flat glass into the tempering furnace, heating to about 650 degrees, with cold air quenching, glass forming hardening - tempering. Accomplish!
