Abstract

The invention discloses opal glaze for electroceramics as well as a preparation method and application of the opal glaze. The opal glaze for the electroceramics is prepared from the following raw materials in percentage by weight: 5-10% of Datong sand, 8-12% of talc, 1-3% of limestone, 4-7% of Faku clay, 9-12% of Baigan stone, 26-34% of feldspar, 17-22% of silica powder, 1-4% of barium carbonate,10-15% of zirconium silicate, 3-4% of Suzhou soil, 1-3% of aluminum oxide and 0.05-0.2% of a dispersing agent. The preparation method comprises the steps of glaze dipping, glaze spraying and roasting.The components in the opal glaze are reasonably matched, aluminum oxide is added on the basis of the prior art to improve the precision of the glaze, and limestone and Suzhou soil are added to increase the high-temperature viscosity of the glaze to adjust the fluidity of the glaze in the high-temperature stage in order to overcome the problems of yellow edges and white edges. The color differenceof white exposure and yellow exposure of the edge part of the product due to too strong fluidity of the glaze in a high-temperature stage is avoided or increased.

Description

technical field [0001] The invention relates to the technical field of electric porcelain, in particular to an opalescent glaze for electric porcelain, a preparation method and a glazing process thereof. Background technique [0002] Electric porcelain is a kind of porcelain electrical insulation material with good insulation and mechanical strength, which is widely used in high and low voltage transmission lines and equipment. The glazing process of electric porcelain can generally be divided into dipping glaze, pouring glaze, spraying glaze, etc., among which the dipping glaze process is more commonly used. With the development of large-scale electric porcelain products, when some large-scale opalescent glaze products such as integrally formed sleeves with larger specifications or inorganic bonded porcelain sleeves are glazed by dipping, yellow edges and water edges will appear in the middle and lower parts of the products. problem, which has seriously affected the econom...
