Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a frosted glass manufacturing process, which has the advantages of self-adjusting the size of the cut glass according to the needs, and also improves the success rate of the pickling process of the plate body, and solves the problems in the traditional situation. Frosted glass is generally used in pickling steps in the processing process. Improper time and infiltration effects may easily cause excessive dissolution of the glass itself, which is not conducive to increasing the success rate of frosted glass processing, and the general frosted glass processing process It is not possible to cut the size of the glass itself, which reduces the problem of the self-cutting effect of the glass size

Embodiment 1

[0025] A manufacturing process of frosted glass, comprising the following steps:

[0026] 1) Put the raw materials in the above ratio, including quartz sand, feldspar, barite, manganese powder, calcium oxide and glass fiber, into the inside of the mill and grind them into powder. The circulating air of the internal blower is brought into the inside of the pulverizer for secondary sorting, and the materials that are too fine will fall back for regrinding. It is necessary to ensure that the grinding diameter of each raw material is less than or equal to 500 mesh, and then the glass that has been sieved Raw materials are taken out;

[0027] 2) Place the mixed and polished glass raw materials in a furnace filled with nitrogen, raise the temperature of the furnace to about 1300°C-1400°C, and then raise the temperature of the furnace to 1460°C-1560°C again to ensure The mixed glass raw materials can be fully heated and melted, and the inside of the furnace is stirred by the machine...

Embodiment 2

[0033] A manufacturing process of frosted glass, comprising the following steps:

[0034] 1) Put the raw materials in the above ratio, including quartz sand, feldspar, barite, manganese powder, calcium oxide and glass fiber, into the inside of the mill and grind them into powder. The circulating air of the internal blower is brought into the inside of the pulverizer for secondary sorting, and the materials that are too fine will fall back for regrinding. It is necessary to ensure that the grinding diameter of each raw material is less than or equal to 600 mesh, and then the glass that has been sieved Raw materials are taken out;

[0035] 2) Place the mixed and polished glass raw materials in a furnace filled with nitrogen, raise the temperature of the furnace to about 1350°C-1450°C, and then raise the temperature of the furnace to 1460°C-1560°C again to ensure The mixed glass raw materials can be fully heated and melted, and the inside of the melting cellar is stirred by the ...

Embodiment 3

[0041] A manufacturing process of frosted glass, comprising the following steps:

[0042] 1) Put the raw materials in the above ratio, including quartz sand, feldspar, barite, manganese powder, calcium oxide and glass fiber, into the inside of the mill and grind them into powder. The circulating air of the internal blower is brought into the inside of the pulverizer for secondary sorting, and the materials that are too fine will fall back for regrinding. It is necessary to ensure that the grinding diameter of each raw material is less than or equal to 700 mesh, and then the glass that has been sieved Raw materials are taken out;

[0043] 2) Place the mixed and polished glass raw materials in a melting furnace filled with nitrogen, raise the temperature of the melting furnace to about 1400°C-1500°C, and then raise the temperature of the melting cellar to 1460°C-1560°C again to ensure The mixed glass raw materials can be fully heated and melted, and the machine is used to stir ...

Abstract

The invention relates to the technical field of glass manufacturing, and discloses a manufacturing process of frosted glass, which is prepared from the following raw materials in parts by weight: 40 to 50 parts of quartz sand, 30 to 40 parts of feldspar, 26 to 30 parts of barite, 8 to 12 parts of manganese powder, 6 to 8 parts of calcium oxide, 5 to 10 parts of glass fiber, 3 to 6 parts of clarifying agent, 2 to 4 parts of mirabilite and 1 to 2 parts of coloring agent. According to the manufacturing process of the frosted glass, in the manufacturing process of the glass, various different raw materials are mixed and fully ground into fine powder, so that bubbles in a product can be well reduced when the raw materials are heated to a molten state, mixing is more uniform, the heating speed is higher, and the effect of improving the glass processing rate is achieved; meanwhile, the manufacturing process can also uniformly spread the glass solution on the surface of the tin liquid, so that the glass can be helped to be cooled and formed more quickly.

Description

technical field [0001] The invention relates to the technical field of glass production, in particular to a production process of frosted glass. Background technique [0002] Glass is an amorphous inorganic non-metallic material, generally made of various inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) of. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O·CaO·6SiO2, etc. The main component is silicate double salt, which is an amorphous solid with an irregular structure. It is widely used in buildings to prevent wind. Translucent, belongs to the mixture. There are also colored glass that is mixed with certain metal oxides or salts to show color, and tempered glass made by physical or chemical methods. Sometimes some transparent plastics (such as polymethyl methacrylate) are also called plexiglass. [0003] However,...
