Abstract

The invention discloses a high-voltage insulation ceramic ash glaze formula which comprises the following components in parts by weight: 26-30 parts of potash feldspar, 20-24 parts of quartz powder, 16-20 parts of kaolin, 4-6 parts of Xinhui kaolin, 6-10 parts of limestone, 6-8 parts of forged talcum, 2.5-4 parts of zirconium silicate, 0.6-0.8 part of ash glaze color base and 1.5-4 parts of barium carbonate. The electric ceramic ash glaze produced according to the formula disclosed by the invention is suitable to be applied on suspended, rod-like, sleeve and other types of ceramic insulators, can greatly enhance the mechanical, electrical and thermal properties of ceramic, and enhances the appearance quality of the high-voltage ceramic, so that the insulator has fine and bright glaze color.

Description

technical field [0001] The invention belongs to the technical field of electric porcelain, and in particular relates to a high-voltage porcelain insulating gray glaze. Background technique [0002] For the glazing of high-voltage porcelain insulators, the pursuit is to comprehensively improve the mechanical, electrical and thermal performance of porcelain insulators, improve the appearance quality of high-voltage porcelain insulators, and then improve the service life of porcelain insulators. However, the traditional gray glaze for electric porcelain, after glazing, is not effective in improving the mechanical, electrical and thermal properties of electric porcelain, especially it cannot greatly improve the mechanical and electrical properties of porcelain, and at the same time, the chemical corrosion resistance and antifouling performance are also poor. not ideal. Contents of the invention [0003] The technical problem to be solved by the present invention is to pr...
