The preparation process of glass and the basic material and the function of raw materials
The main raw materials are: silica glass (sandstone), sodium carbonate, feldspar, dolomite, limestone and mirabilite.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: liquid glass forming device with the corresponding sheet glass, bottles, glass, lamp, glass tube, a fluorescent screen......6, annealing: the molding of a variety of glass products into the annealing furnace annealing, balance stress, to prevent self cracking
Feldspar provides Al2O3 and enhances chemical stability in glass;Glauber's salt helps the high temperature glass to remove bubbles produced by carbonates in other materials
Silica sand, quartz sand or sandstone with SiO2 framework structure for glass, glass forming;The role of soda to help melting sand;
