Problems solved by technology

[0003] At present, in the production process, it is found that the yield of wet billet is low and it is easy to deform, which seriously affects the pass rate of porcelain inspection of the product and increases the production cost
The reason is that the large-scale overall molding of large-scale products has a high height, poor plasticity of the billet, and the strength of the wet billet is not enough, which is prone to cracks and even deformation, resulting in low product yield

Abstract

The invention discloses a formula of a wet-method high-strength electrical porcelain blank. According to the formula, the high-strength electrical porcelain blank comprises the following components in percentage by weight: 35%-40% of alumina, 5%-10% of feldspar solvent, 30%-40% of kaolin and10%-20% of illite clay. As high plastic clays such as kaolin and illite clay are adopted in the formula, the wet blank strength of the formula is improved, the formability of the formula is enhanced, the process property of an electrical porcelain blank is excellent, the preparation cost is reduced, the formula can meet the production demands of an overall formed product which is higher than 3 meters, and the phenomenon such as falling caused by poor plasticity of the blank formula during fettling can be reduced.

Description

technical field [0001] The invention belongs to the field of electric porcelain manufacturing, and relates to a wet-process high-strength electric porcelain blank formula. Background technique [0002] With the rapid development of the power transmission and transformation industry, the number of domestic electric porcelain manufacturers has increased rapidly. In order to occupy the market, various electric porcelain manufacturers have lowered their prices. In recent years, the prices of electric porcelain products have dropped again and again, in order to obtain profits. With the continuous development of the electric porcelain industry, the requirements for electric porcelain products in the field of power transmission are getting higher and higher, and the demand for large porcelain sleeve products is increasing day by day. For forming the overall large-scale waist-drum product, such large-scale porcelain sleeve products have a high slender-height ratio coefficient, and t...
