Milky white frit for glaze and preparation method for milky white frit for glaze

Abstract

The invention relates to milky white frit for glaze and belongs to the technical field of ceramics. The milky white frit comprises the following components in part by weight: 5 to 15 parts of potash feldspar, 15 to 25 parts of quartz, 15 to 25 parts of soda feldspar, 5 to 15 parts of dolomite, 1 to 3 parts of calcium carbonate, 8 to 15 parts of zinc oxide, 10 to 15 parts of zirconium silicate, 1 to 5 parts of potassium carbonate, 2 to 10 parts of boric acid, 0.5 to 2 parts of barium carbonate, and 1 to 5 parts of aluminum oxide. A preparation method comprises the following steps of: uniformly mixing and stirring the components, melting in a high-temperature frit furnace at the temperature of between 1,500 and 1,600 DEG C for 1.5 to 2.0 hours, and performing water quenching on the melted liquid by using cold water to obtain the milky white frit. The frit for the glaze is high in mobility, low in viscosity, high in glossiness and flatness, and wide in firing temperature range; and quality and yield of a product is improved, and the yield of the product is greatly improved.

Description

technical field [0001] The invention relates to a frit, in particular to an opalescent frit for glaze and a preparation method thereof, belonging to the technical field of ceramic frit. Background technique [0002] Glaze quality is one of the main factors affecting ceramic products. The poor quality of white glaze is reflected in the lower whiteness of the glaze, poor gloss and more pinholes, which cannot meet the requirements of the product, and at the same time, reduce the quality of the product. , affecting the quality of ceramics. [0003] The key to the development of milky white glaze is to solve the common defects in the production of milky white glaze, such as high temperature viscosity, easy glaze shrinkage, orange glaze, patterned glaze, dull glaze and other defects. Therefore, in order to solve these defects of milky white glaze, domestic and foreign Most of the production of white glazed tiles uses frit glaze to improve the quality of the glaze surface. In ...

[0003] The key to the development of milky white glaze is to solve the common defects in the production of milky white glaze, such as high temperature viscosity, easy glaze shrinkage, orange glaze, patterned glaze, dull glaze and other defects. Therefore, in order to solve these defects of milky white glaze, domestic and foreign Most of the production of white glazed tiles uses frit glaze to improve the quality of the glaze surface. In order to meet the needs of customers, some glaze companies have developed milky white frit glazes. Some milky white frits currently on the market either have poor whiteness or gloss Poor temperature, poor high-temperature fluidity, and narrow firing range have affected the quality of the product. Therefore, through continuous exploration and experimentation, a satisfactory milky white glaze formula should be optimized to eliminate various defects in production and improve the quality of the company's products. High quality, solve the technical problems of milky white glaze production, reduce glaze pinholes, improve glaze whiteness and gloss, and make product quality a step up
