Problems solved by technology

In the float glass production line, the melted glass melt flows into the tin bath, and when the glass is pulled out of the tin bath, it has formed solid glass plates with different widths and thicknesses; It takes only a few minutes to ten minutes to cool down to the annealing temperature (about 600°C). Such a fast cooling rate obviously cannot meet the time requirements for microcrystallization of most system glass-ceramics disclosed so far.
The glass-ceramic and its production proc

Abstract

The invention discloses a method for producing glass from purified granite scrap. The method comprises the following steps: weighing the following raw materials in parts by weight: 20-45 parts of high-whiteness potash feldspar and soda feldspar powder, 10-35 parts of spodumene, 20-45 parts of leucite, 15-45 parts of kieselguhr, 10-40 parts of magnesite, 5-25 parts of plant ash, 3-20 parts of graphene, 1-12 parts of potassium acetate, 5-25 parts of zinc oxide, 1-20 parts of calcium sulfide and 1-20 parts of mirabilite; uniformly mixing the high-whiteness potash feldspar and soda feldspar powder, the spodumene, the kieselguhr and the leucite, performing microwave roasting, adding water to prepare a suspension, performing high-speed grinding, and performing spray drying to obtain powder particles; uniformly mixing the powder particles with the magnesite, the plant ash and the graphene, and heating until all the materials are molten; and adding the remaining raw materials, stirring, blanking, performing water quenching, drying, smelting, and molding through a mold to obtain the glass. The glass produced by the invention has excellent chemical corrosion resistance, is especially tolerant to strongly-acidic and strongly-basic environments, has long service life and high refractivity, can meet the corrosion resistance requirements of different reflecting films, and has a wide application range.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a method for producing glass by utilizing granite waste. Background technique [0002] Glass plates used for architectural decoration are building materials with a large amount of consumption. However, until now, the production process of architectural glass plates is still limited to high-cost, low-efficiency small-scale production, and the float process cannot be used like ordinary flat glass. Large-scale, efficient production. The float process proposed by Pilkington, PPG and CLFG in the world today is an advanced technology for manufacturing high-quality, low-cost flat glass. High forming speed is one of the main characteristics of the float production process. In the float glass production line, the melted glass melt flows into the tin bath, and when the glass is pulled out of the tin bath, it has formed solid glass plates with different widths and thicknesses; I...
