Problems solved by technology

[0002] The ceramic glaze is melted by firing at a certain temperature. When the temperature drops, a glassy thin layer on the surface of the ceramic is formed, which increases the mechanical strength, thermal stability, and dielectric strength of the ceramic and prevents liquid and gas erosion. The glaze also increases. Porcelain is beautiful, easy to clean, and not stained by dust. Various decorations can be used on the glaze to enhance the artistic effect of the product. However, the enamel currently used in the glass-lined industry is general-purpose acid-resistant enamel, and its alkali resistance cannot meet the requirements. Alkali medium users require special alkali-resistant enamel; therefore, it is very necessary to provide a high-quality alkali-resistant enamel

Abstract

The invention relates to alkali-resistant porcelain glaze. The porcelain glaze is prepared from raw materials in parts by weight as follows: 40-50 parts of silicon dioxide, 4-10 parts of diboron trioxide, 3-8 parts of lithium oxide, 2-8 parts of potassium oxide, 2-8 parts of sodium oxide, 10-15 parts of zinc oxide, 7-12 parts of titanium oxide, 1-2 parts of cobalt oxide, 4-7 parts of zirconium oxide, 4-7 parts of aluminum oxide, 3-8 parts of limestone and 3-8 parts of clay. In a word, the porcelain glaze has the advantages of alkali resistance and good glossiness, fineness and elasticity.

Description

technical field [0001] The invention belongs to the technical field of porcelain manufacture, and in particular relates to an alkali-resistant enamel. Background technique [0002] The ceramic glaze is melted by firing at a certain temperature. When the temperature drops, a glassy thin layer on the surface of the ceramic is formed, which increases the mechanical strength, thermal stability, and dielectric strength of the ceramic and prevents liquid and gas erosion. The glaze also increases. Porcelain is beautiful, easy to clean, and not stained by dust. Various decorations can be used on the glaze to enhance the artistic effect of the product. However, the enamel currently used in the glass-lined industry is general-purpose acid-resistant enamel, and its alkali resistance cannot meet the requirements. The requirements of users of alkali medium require special alkali-resistant enamel; therefore, it is very necessary to provide a high-quality alkali-resistant enamel. Content...
