Problems solved by technology

These glaze defects affect the qualification rate of ceramic products. If the repair can be effectively repaired and does not affect the use of product defects that exceed the national standard, refiring and repairing can not only improve the product qualification rate, but also shorten the production cycle and reduce production costs. , can continue to be used without affecting the performance of the product, therefore, it is necessary to design a repair material and its repair method
The original traditional method is to repair the cracked part of the mud by adding the original mud and then compacting it with water. This method only temporarily fills the cracked space of the original mud and does not strengthen the broken particle connection. It is easy to cause secondary cracking during the process

Abstract

The invention discloses a repairing material, comprising the following raw materials by weight: 50-70 parts of repairing mud, 1-5 parts of porcelain powder, 1-3 parts of adhesive, 1-50 parts of water and 20-30 parts of water The organic solvent, wherein the blank-filling mud includes A formula mud and B formula mud; the present invention can enhance the reinforcement between the blank mud and the blank-filling mud at the cracked part of the electric porcelain blank by adding adhesive and porcelain powder, and effectively avoid The phenomenon of secondary cracking in the subsequent drying or firing process; the invention also discloses a repairing method for applying a repairing material to a high-voltage electric porcelain blank. Adhesive, the adhesive solution itself improves the bonding effect between the electric porcelain body and the filling mud, increases the graininess of the cracked place between the adhesive and the green body and the filling mud, and enhances the adhesion of the adhesive. In the subsequent firing process, the melting of the porcelain powder in the mixed adhesive will be more closely combined with the melting mud and the green body.

Description

technical field [0001] The invention relates to the field of electric porcelain, in particular to a repairing material and a repairing method applied to a high-voltage electric porcelain blank. Background technique [0002] In the prior art, in the production process of high-voltage electric porcelain, there are various defects to varying degrees, such as glaze cracks, lack of glaze, glaze stains and other glaze defects caused by drying conditions and transportation. These glaze defects affect the qualification rate of ceramic products. If repairing can be effectively repaired without affecting the use of super-national standard product defects, re-firing and repairing can not only improve the qualified rate of products, but also shorten the production cycle and reduce production costs. , it can continue to be used without affecting the performance of the product. Therefore, it is necessary to design a repair material and its repair method. The original traditional method u...
