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.
