Production process of microcrystalline tile

Abstract

The invention provides a production process of a microcrystalline tile. The production process of the microcrystalline tile comprises the following steps: (1) selecting raw mineral materials, mixing and carrying out ball milling to obtain slurry; (2) carrying out spray drying of the slurry to obtain powder, and wherein by measuring and controlling, the content of water in the powder to beis 6.8-7.4% of water, and measuring and controlling the particle grading composition to beis formed by less than 1% of 20-mesh particles, 35-47% of 40-mesh particles, 50-62% of 80-mesh particles and less than3% of particles with size being smaller than 100 meshes; (3) pressing and molding the powder to obtain a tile blank; (4) drying the tile blank, and measuring and controlling the process parameters ofthe tile blank; and (5) glazing through the substeps of a, spraying microcrystalline ground glaze on the surface of the tile blank according to a dosage of 130+ / -2g / tray and a specific gravity ratio of 1.45+ / -0.02g / ml; b, spraying ink on the surface of the tile blank; c, carrying out screen printing of color protecting glaze on the surface of the tile blank by using a 100-mesh sieve according to aspecific gravity ratio of 1.55+ / -0.02g / ml; d, spraying transparent glaze on the surface of the tile blank according to a dosage of 60-70g / tray and a specific gravity ratio of 1.47+ / -0.02g / ml; e, coating applying frit on the surface of the tile blank according to a dosage of 780+ / -20g / tray; f, spraying clear water methyl on the surface of the tile blank according to a dosage of 40+ / -2g / tray; firing and polishing to obtain the microcrystalline tile. The production process of the microcrystalline tile is has the advantages of being more accurate in quality control, higher in rate of finished products and more stable in production quality; the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic processing, in particular to a production process of microcrystalline bricks. Background technique [0002] In the current production process of microcrystalline bricks, glaze production and billet pressing are usually separately processed and controlled. Finally, the quality of bricks often needs to be graded. If there are microcrystalline bricks that fail to meet the quality requirements of the lowest level, If they are treated as waste bricks, the rate of waste products is often high, especially the unreasonable operation in the process of blank and glaze line processing, and the indirect factors affecting the quality of bricks in different steps are not considered uniformly, and a complete set is lacking. Accurately measure and control the production quality of microcrystalline bricks, and its parameters cannot be effectively measured and controlled, resulting in low production q...

[0002] In the current production process of microcrystalline bricks, glaze production and billet pressing are usually separately processed and controlled. Finally, the quality of bricks often needs to be graded. If there are microcrystalline bricks that fail to meet the quality requirements of the lowest level, If they are treated as waste bricks, the rate of waste products is often high, especially the unreasonable operation in the process of blank and glaze line processing, and the indirect factors affecting the quality of bricks in different steps are not considered uniformly, and a complete set is lacking. Accurately measure and control the production quality of microcrystalline bricks, and its parameters cannot be effectively measured and controlled, resulting in low production quality of microcrystalline bricks, low yield, and easy to cause waste, increase production costs, and control the quality of bricks. difficult question
