Problems solved by technology

However, in the prior art, limited to the relatively low silicon-aluminum composition in matt glazes, matt glazes generally have the problem of low high-temperature fluidity, so the temperature range for crystal precipitation is small, and the precipitated crystals are generally single crystals. The texture of the glaze surface is poor. In addition, it is difficult to control the flatness of the glaze surface, which increases the difficulty of firing sanitary ceramics and reduces the firing efficiency of sanitary ceramics.

preparation example Construction

[0046] A preparation method for sanitary ceramics, using the above-mentioned matt glaze, comprising the following steps:

[0047] Pre-milling of frit: Weigh the frit according to the ratio, and grind the frit of the recipe amount to particles with a fineness of 325 mesh or less;

[0048] Ball milling: Weigh other raw materials according to the ratio, mix other raw materials with the frit after ball milling in advance, add methyl cellulose, and then ball mill with water to obtain glaze slurry, wherein the amount of methyl cellulose added is 1% of the total weight of raw materials 0.15-0.20%, the amount of water added is 45-50% of the total weight of raw materials;

[0049] Sieving and removing iron: the glaze slurry obtained by the ball mill is sieved with 160-200 mesh and iron is removed;

[0050] Glazing: glaze the body of sanitary ceramics, and the thickness of the glaze layer is 0.6-0.8mm;

[0051] Drying: put the body of the glazed sanitary ceramics in a drying room at 5...

Embodiment 1

[0073] In Example 1, the addition of methylcellulose is 0.15% of the total weight of raw materials, and the addition of water is 45% of the total weight of raw materials. The thickness of the glaze layer of 200 mesh sieve and de-iron glazing is 0.6mm, and the firing temperature is 1195°C;

Embodiment 2

[0074] In embodiment 2, the addition of methyl cellulose is 0.20% of the total weight of raw materials, the addition of water is 50% of the total weight of raw materials, the thickness of the glaze layer of 160 mesh sieve and de-iron glazing is 0.8mm, and the firing temperature It is 1215°C.

[0075] The addition amount of methyl cellulose among the embodiment 3~9 is 0.18% of raw material total amount, and the addition amount of water is 48% of raw material total amount, carries out 180 order sieves and the thickness of the glaze layer of glazing 0.7mm that removes iron, burns The temperature is 1210°C;

[0076]

[0077] The chemical composition requirements of some raw materials in Table 1: the content of potassium oxide in the potassium feldspar is greater than or equal to 10%; the content of calcium oxide in the dolomite is greater than or equal to 28%, and the content of magnesium oxide in the dolomite is greater than or equal to or equal to 15%; the content of calcium...

Abstract

The invention discloses a matte glaze applied to sanitary ceramics, the sanitary ceramics applying the matte glaze and a preparation method, and relates to the technical field of sanitary ceramics. The matte glaze applied to sanitary ceramics comprises the following raw materials by weight: 25-27 parts of potassium feldspar, 17-20 parts of quartz, 1-3 parts of zinc oxide, 8-12 parts of dolomite, 5-8 parts of wollastonite, 5-8 parts of kaolin, 6-8 parts of aluminum oxide, 7-9 parts of zirconium silicate, 1-4 parts of frit, 6-9 parts of barium carbonate, 5-9 parts of calcined talc and 0.5-1.5 parts of lithium carbonate. A certain quantity of lithium carbonate is introduced to achieve fluxing, the melting temperature of the raw materials is reduced, mutual fusion of the raw materials is facilitated, the viscosity of the frit is improved through lithium carbonate, the viscosity of the matte glaze is reduced, the flowing property of the matte glaze at high temperature is improved, flowing of crystals separated out of the matte glaze is facilitated, the crystals are arranged more uniformly and orderly, the glaze surface flatness is conveniently controlled, and the sanitary ceramic firingefficiency is improved.

Description

technical field [0001] The invention relates to the technical field of sanitary ceramics, in particular to a matt glaze applied to sanitary ceramics, sanitary ceramics using the same and a preparation method. Background technique [0002] Matte glazes can be divided into Ca matte glazes, Mg matte glazes, Ba matte glazes and Zn matte glazes, which precipitate a single crystal according to the different types of crystal structures. There are also a variety of crystals that can be precipitated. The Ca-Mg matt, Ba-Mg matt and Ca-Mg-Ba matt glazes, the study found that matt glazes with multiple crystal structures have better glaze texture, and the glaze is more delicate than single glazes. The matte glaze of the crystal has been significantly improved, and the sanitary ceramics made of the matte glaze with a variety of crystals have a good glaze texture. However, in the prior art, limited to the relatively low silicon-aluminum composition in matt glazes, matt glazes generally ha...
