Preparation method of material for electrical porcelain body and electrical porcelain body

Abstract

The invention relates to the technical field of electrotechnical porcelain production, and discloses a preparation method of a material for an electrical porcelain body, and the electrical porcelain body. The preparation method comprises the following steps: a, taking 10-15 parts of Faku (Chinese county) soil, 20-22 parts of fraxinus mandshurica soil, 40-50 parts of high-aluminum powder, 4-6 parts of Kuancheng (Chinese county) soil, 5-7 parts of Zuoyun (Chinese county) soil, 8-12 parts of feldspar powder and 1-2 parts of bentonite according to the weight ratio; b, adding 180-200 parts of water to a mixture in the step a and grinding; and c, filtering the materials by a 200-325mesh sieve after grinding until the screen residue is smaller than 1%. The electrical porcelain body is a porcelain body prepared from the slurry prepared by using the method in manners of molding and sintering. The electrotechnical porcelain produced by the preparation method of the material for the electrical porcelain body has the advantages of low wind convulsion rate, low water absorption and low cost. The electrical porcelain body has the advantages of low water absorption and low cost.

Description

technical field [0001] The invention relates to the technical field of electric porcelain production, in particular to a method for arranging materials for an electric porcelain body, and also relates to an electric porcelain body made by the method. Background technique [0002] On the one hand, when the electric porcelain body is fired, it is necessary to prevent wind shock. Wind shock is the crack caused by the product encountering cold air when it leaves the kiln. The product with wind shock is a waste product. A better electric porcelain body formula can make The wind startle rate is reduced to the minimum, or even the degree of no wind startle. On the other hand, a better formula also requires the electric porcelain body to have the lowest water absorption rate. The lower the water absorption rate, the better the insulation performance, the less sparks will be generated, the breakdown is not easy, and the use is safer. The configuration method is directly related to t...

Problems solved by technology

[0003] The production of electric porcelain has been in production for a long time, and there are many manufacturers. Various manufacturers and research institutes have developed many formulas, and these formulas have produced many high-quality electric porcelains. These electric porcelains have played a huge role in national construction, but After a long period of development and utilization of some raw materials, resources are facing depletion, resulting in higher prices of raw materials and higher production costs, which cannot meet the needs of actual production. How to develop and utilize cheap raw materials to produce less wind shock rate and less water absorption rate , low cost, high strength, and good electrical performance have become the primary tasks of all electric porcelain manufacturers and research units
