Abstract

The invention discloses a production process of an insulating ceramic for power equipment. The production process comprises the following steps: firstly, carrying out pretreatment on polygonatum odoratum; secondly, preparing a mixed raw material; thirdly, sintering and moulding, heating the mixed raw material to 80-120 DEG C within 40-50 minutes at a rate of 10 DEG C per minute, adding a sintering additive, and carrying out ball milling for 12-24 hours so that slurry with the solid phase content of 50-75vol is obtained, preparing the slurry into a transparent ceramic blank which is 1-3mm thick, heating the blank to 1400 DEG C in a high temperature box-type furnace at a rate of 2 DEG C / min, moulding in a perfusion mould, and carrying out heat preservation for 1.5-2.5 hours after moulding is carried out for 20-90 seconds, so that the insulating ceramic for the power equipment is obtained. The production process disclosed by the invention has the advantages that structural changes and chemical changes of the insulating ceramic material in a sintering process can be controlled by strictly controlling technological parameters, industrial application requirements can be met, and the production process can obviously reduce energy consumption compared with an existing process.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a manufacturing process of 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 electronics. A...
