Method for preparing insulating ceramic for electrical equipment

Abstract

The invention discloses a method for preparing an insulating ceramic for electrical equipment. Quartz stone, limestone, clay, potassium-sodium feldspar, inorganic phosphate, calcite powder, zinc oxide, bentonite, kaolin, dolomite powder, black mud, knar clay and distilled water are used as raw materials, the ratios of the components are strictly controlled, and a traditional insulating ceramic manufacturing formula is optimized, so that the material sources are wide, and the raw material cost is saved; the water temperature can be controlled easily by using a water bath heating method so as toensure the temperature environment of preparation, and after molding of the ceramic is conducted, polishing treatment is conducted on the obtained ceramic by an operator through a grinding device, sothat burrs at edges of the ceramic is removed, and the processing quality is improved; furthermore, the humidity and temperature of the storage environment of the materials are controlled, ultraviolet sterilization treatment is conducted on the materials before a packaging machine is adopted to perform quantitative sealing and packaging, and the mixture which does pass through a sieve passes through the sieve in a mode of repeated forced crushing, so that waste of the materials is avoided; the method has a simple preparation process and low preparation cost.

Description

technical field [0001] The invention belongs to the technical field of electric equipment, and more specifically relates to a method for making insulating ceramics for electric equipment. Background technique [0002] Ceramics are various products made of natural clay and various natural minerals as the main raw materials through crushing, kneading, molding and calcination. In the past, people called ceramics made of clay and fired at high temperature in special kilns. Ceramics is the general term for pottery and porcelain. The traditional concept of ceramics refers to all artificial industrial products that use inorganic non-metallic minerals such as clay as raw materials. It includes various products made of clay or a mixture containing clay through kneading, shaping, and calcination. It ranges from the roughest earthenware to the finest fine pottery and porcelain. There are many types of ceramics, and they are widely used in the fields of chemical industry and electron...
