Problems solved by technology

The disadvantages of this kind of glass batch material are: high cost of raw materials, high melting temperature of glass, generally between 1500-1550°C, such high temperature will inevitably increase fuel consumption and intensify the erosion of glass liquid on refractory materials of kiln; in addition, due to There are many chemical raw materials in the glass batch, which also increases the erosion of the glass liquid on the refractory material of the furnace, which affects the service life of the equipment

Embodiment 1

[0019] The glass batch is made by weighing and mixing. The composition of the glass batch is calculated in parts by weight: 70 parts of coal gangue, 24 parts of quartz, 8.5 parts of calcite, 4 parts of alumina, 9 parts of sodium carbonate, 5 parts of zinc oxide, 3 parts of barium carbonate.

[0020] Put the above-mentioned glass batch material in a mullite crucible and melt it in a box-type electric furnace at a temperature of 1460°C for 3.5 hours. After the melting is completed, pour the glass liquid into water to become glass pellets. 500 grams of glass granules were spread flat in a refractory mold with a size of 120×120 mm and crystallized in a box-type electric furnace at a crystallization temperature of 1020° C. A gray-black microcrystalline stone sample of 120×120×18 mm can be obtained.

Embodiment 2

[0022] The glass batch is made by weighing and mixing. The composition of the glass batch is calculated in parts by weight: 40 parts of coal gangue, 40 parts of quartz, 21 parts of calcite, 4.7 parts of alumina, 9 parts of sodium carbonate, 4 parts of zinc oxide, 5 parts of barium carbonate, 0.6 parts of copper oxide, and 0.5 parts of carbon powder.

[0023] The above-mentioned glass batch materials were melted in a glass tank furnace with a temperature of 1470° C. for 3.5 hours. After the melting was completed, the molten glass was directly poured into water to become glass pellets. Spread 20 kg of glass granules flat in a refractory mold with a size of 6000×9000 mm to carry out crystallization in a shuttle kiln fueled by liquefied petroleum gas, and the crystallization temperature is 1070°C. A copper-red microcrystalline stone product of 600×900×16 mm can be obtained.

Embodiment 3

[0025] The glass batch is made by weighing and mixing. The composition of the glass batch is calculated by weight: 40 parts of coal gangue, 42 parts of quartz, 18 parts of calcite, 4 parts of alumina, 7 parts of sodium carbonate, 6 parts of zinc oxide, 6 parts of barium carbonate, 0.1 part of copper oxide, 0.6 part of carbon powder.

[0026] The above-mentioned glass batch materials were melted in a glass tank kiln at a temperature of 1470° C. for 4 hours, and after the melting was completed, the molten glass was directly flowed into water to become glass pellets. Spread 26 kg of glass pellets in a refractory mold with a size of 6000×9000 mm and crystallize in a shuttle kiln fueled by liquefied petroleum gas at a crystallization temperature of 1050°C. A pink microcrystalline stone product of 600×900×18 mm can be obtained.

Abstract

The invention discloses a method utilizing a coal gangue to manufacture a microcrystalline glass plate material. The method includes the following steps: the coal gangue, quartz sand, calcite, alumina, sodium carbonate, zinc oxide, barium carbonate, copper oxide, carbon powder, borax and chromic oxide are mixed together according to certain parts by weight so as to obtain a glass batch mixture; the glass batch mixture is molten into liquid glass; the liquid glass is poured into water to obtain glass particles; the glass particles are laid in a fireproof mould to carry out crystallization heat treatment; finally, the rough microcrystalline glass is ground and cut after the crystallization heat treatment so as to obtain the finished glass. The method in the invention utilizes wastes in the coal mining industry to manufacture the microcrystalline glass plate material, which not only reduces the stacking quantity of the coal gangue and lessens environmental pollution, but also improves the product performance and reduces the production cost. Therefore, the method in the invention has good social and economic benefits.

Description

technical field [0001] The invention relates to a method for manufacturing a glass-ceramic plate, in particular to a method for manufacturing a glass-ceramic plate with coal gangue. Background technique [0002] Glass-ceramic is a polycrystalline material obtained by controlling the crystallization of glass. At present, glass-ceramics has formed a special category of materials, with various varieties and different properties, and has a very wide range of uses. Glass-ceramic plate is one of many varieties of glass-ceramics. It is a new type of high-grade building decoration material with high strength, wear resistance, corrosion resistance, weathering resistance, non-absorbent, easy cleaning and maintenance, and no radioactive pollution. Excellent physical and chemical properties and uniform color tone, soft and crystal-clear luster, compact and flawless surface and other excellent appearance characteristics. Because the properties of the glass-ceramic plate are superior to...
