Problems solved by technology

However, since the low-temperature glaze firing cycle is generally about 160 minutes, it is several times slower than the high-temperature biscuit firing time (50-70 minutes) of the first firing, which will cause a lot of inconvenience in production
Firstly, the cost of firing is higher than that of general one-time firing; in addition, the bricks supplied by the bisque firing line are larger than the demand of the glaze firing line, and the excess bricks need to be removed manually, and then mov

Embodiment 1

[0031] Weigh 4 parts of boric acid, 3 parts of borax, 10 parts of potassium feldspar, 33 parts of quartz, 25 parts of dolomite, 4 parts of barium carbonate, 11 parts of non-calcined alumina, 5 parts of zirconium silicate, 5 parts of fluorite, chromium oxide 0.5 parts, mixed evenly, melted at 1460°C, kept warm for 3 hours, discharged, quenched, dried, and granulated. The fineness of the dry frit granules was controlled at 10-30 meshes, and a dry chromium-fired green frit was obtained. grains, such as figure 1 As shown, the chrome-green frit dry particles have good gloss and are translucent, shining under the light.

Embodiment 2

[0033] Weigh 2 parts of boric acid, 2 parts of borax, 15 parts of potassium feldspar, 33 parts of quartz, 25 parts of dolomite, 2 parts of barium carbonate, 11 parts of non-calcined alumina, 5 parts of zirconium silicate, 3 parts of fluorite, chromium oxide 0.8 parts, mix evenly, melt at 1480°C, keep warm for 2.5 hours, discharge and quench in water, dry, and granulate. The fineness of the dry granules of the frit is controlled at 10-30 meshes, and a dry chrome-fired green frit is obtained. grain.

Embodiment 3

[0035] Weigh 3 parts of boric acid, 4 parts of borax, 8 parts of potassium feldspar, 35 parts of quartz, 28 parts of dolomite, 4 parts of barium carbonate, 7 parts of non-calcined alumina, 5 parts of zirconium silicate, 8 parts of fluorite, chromium oxide 1.0 parts, mix evenly, melt at 1450°C, keep warm for 3 hours, discharge and quench in water, dry, and granulate. The fineness of the dry granules of the frit is controlled to 10-30 meshes, and the dry chromium frit is obtained once. grain.

Abstract

The invention discloses one-time sintered chrome green frit dry particles and a preparation method thereof. The frit dry particle preparation raw materials comprise boric acid, borax, feldspar, quartz, dolomite, barium carbonate, non-calcined alumina, zirconium silicate, fluorspar, and chromium oxide. The frit dry particles have an intrinsic chrome green color and good gloss, and are semitransparent. The particles are shiny under light. Because the frit dry particles have the intrinsic chrome green color, a ceramic factory glaze line printing process can be eliminated, glaze line length can be reduced, related staffs can be reduced, modularization collection degree is improved, production efficiency is improved, cost of ceramic enterprises is reduced, and quality controllability is improved. The frit dry particles can be used in a one-time sintering method for preparing microcrystalline tiles. The sintered microcrystalline tile surface glaze has a glistening gentle chrome green color and no pore which is visible to naked eyes. With the one-time sintering process, energy can be saved, emission can be reduced, and consumption can be reduced by approximately 15% than that of twice sintering.

Description

technical field [0001] The invention belongs to the technical field of ceramic frit production, and in particular relates to a dry granule of green chromium frit fired once and a preparation method thereof. Background technique [0002] The natural stone texture is soft, beautiful and elegant, with elegant style. However, large-scale natural stone is extremely scarce and has certain radioactivity. Glass-ceramics is a mixture of microcrystals and glass formed by sintering and crystallizing glass with a certain particle size distribution. The texture is firm and crystal clear. However, glass-ceramic is relatively single in the pattern design process. Antique bricks can make up for this, and thousands of designs can be obtained through micro-powder cloth, screen, roller or inkjet technology to satisfy more consumers. But it does not have the spatial three-dimensionality and crystal clearness of stone and glass-ceramic. The microcrystalline brick is a new type of product th...
