Problems solved by technology

[0004] The raw materials used in the above-mentioned glaze formula are complicated, it is difficult to control the dosage in actual operation, and the cost of raw materials is increased
The problems in production are more prominent. One is that the long firing process conflicts with the current fast-paced production mode, and it is difficult to match the existing kiln curve to produce a uniform and delicate matte glaze; the other is the nature of the glaze itself. Severe defects of delamination and blistering during glaze spraying have a low pass rate

Embodiment Construction

[0021] The present invention is described in detail below in conjunction with embodiment.

[0022] A kind of black matte glaze for ceramic production, the chemical composition of the raw materials used after drying is by weight percentage, including:

[0023] Quartz: SiO 2 >98%, Fe 2 o 3 <3%, IL<1%;

[0024] Feldspar: SiO 2 65~69%, Al 2 o 3 17~21%, Fe 2 o 3 2 2 O+Na 2 O>10%, IL<1%;

[0025] Alumina: Al 2 o 3 >98%, IL<0.5%;

[0026] Kaolin: SiO 2 45~53%, Al 2 o 3 32~38%, CaO 0~2%, MgO 0~2%, Fe 2 o 3 2 2 O0~3%, Na 2 O 0~2%, IL 10~15%;

[0027] Wollastonite: SiO 2 50~54%, CaO 42~44%, IL 2~4%;

[0028] Dolomite: CaO 28~30%, MgO 21~23%, IL45~48%;

[0029] Burnt talc: SiO 2 58~62%, MgO 29~32%.

[0030] The raw material dry material contains the following components: 28% of quartz, 12% of feldspar, 7% of alumina, 7% of kaolin, 16% of wollastonite, 4% of dolomite, 19% of calcined talc, and 7% of cobalt black material.

[0031] In the above embodiment, th...

Abstract

The invention relates to the technical field of sanitary ceramic manufacturing, in particular to black matte glaze for ceramic production. The black matte glaze comprises the following dry raw materials in percentage by weight: 26-33% of quartz, 10-15% of feldspar, 5-10% of aluminum oxide, 5-10% of kaolin, 14-19% of wollastonite, 3-5% of dolomite, 16-24% of calcined talc and 6-10% of cobalt black pigment. The black matte glaze produced by the invention has the advantages that the glaze surface of a fired finished product is fine, smooth, moist and free of strong reflection, the black matte glaze has an opaque matte surface, brings a soft, quiet and comfortable visual feeling to people and is mainly applied to high-end-face basin products.

Description

technical field [0001] The invention relates to the technical field of manufacturing sanitary ceramics, in particular to a black matte glaze for ceramic production used in high-end basin products. Background technique [0002] Ceramic glazes can be divided into bright glazes and matte glazes, both of which have different glaze textures and states. The glaze surface of matte glaze is fine, moist, non-strongly reflective, and has an opaque matte surface, giving people a soft, quiet and comfortable visual experience, which can ensure the visual effect of the product. [0003] The Chinese patent with the publication number CN201811527376.2 discloses a black matte glaze made of the following raw materials in parts by weight: 3-7 parts by weight of kaolin, 25-35 parts of quartz, 15-20 parts of potassium stone, talc 10-20 parts of powder, 3-7 parts of low-temperature frit, 5-10 parts of bovine bone ash, 5-13 parts of iron ore, 1-5 parts of manganese oxide, 1-5 parts of tricobalt t...
