Problems solved by technology

At present, there have been studies on the use of coal gangue to prepare ceramic tiles, but they are mainly used in the formula of ceramic blanks, and the substitution amount is small, because the coal gangue waste residue has more impurities, which will affect the performance of ceramic blanks.
However, there is no research on this

Abstract

The invention relates to the technical field of ceramic glazed tiles, in particular to a ceramic glazed tile glaze prepared from coal gangue, and a preparation method and use method of the ceramic glazed tile glaze. The ceramic glazed tile glaze is prepared from 1-5 parts of zinc oxide, 4-10 parts of barium carbonate, 4-12 parts of zirconium silicate, 30-40 parts of potassium feldspar, 2-10 partsof desiliconized aluminum powder, 6-14 parts of calcined talc, 2-8 parts of calcite, 6-12 parts of kaolin, 6-12 parts of dolomite, 3-8 parts of quartz and 5-12 parts of coal gangue waste residues, wherein the fineness of the coal gangue waste residues is that screening residues of 60 meshes is 10-20%, and the mass content of water is 1-2%. According to the glaze, the cheap coal gangue waste residues are adopted to replace high-cost calcined kaolin, so that cost of the glaze is greatly reduced, and raw material cost per ton can be reduced by 60% or above. In addition, the texture and luster ofthe glaze surface are finally ensured to meet use requirements by controlling the glaze slurry performance, the glaze formula and the glazing conditions.

Description

technical field [0001] The invention relates to the technical field of porcelain glazed tiles, in particular to a porcelain glazed tile glaze prepared from coal gangue and a preparation method and application method thereof. Background technique [0002] In recent years, the ceramic industry has developed rapidly, and the demand for raw materials is also increasing. As we all know, mineral resources are non-renewable resources. Most ceramic companies are constantly improving the whiteness of ceramic bodies and improving the market competitiveness of their products. However, high-quality raw materials are decreasing day by day, and the rise in raw material prices directly leads to high production costs. Amplitude rises. Therefore, developing new raw materials, reducing production costs and improving product quality is a new research direction in the current ceramic industry. [0003] With the development of industry, the demand for electricity in the domestic market is incr...
