Electric ceramic material for recycling existing electric ceramic wastes for reproduction, and production method thereof

Abstract

The invention relates to a remanufactured electric porcelain material and a manufacturing method thereof by recycling existing electric porcelain waste materials. There is an impurity problem in the reuse of the waste generated in the manufacturing process of electric porcelain products. The present invention weighs 50-73 parts of electric porcelain waste, 15-25 parts of bauxite, 3-17 parts of clay, 1-8 parts of potassium feldspar, 0.5-2 parts of zinc oxide, and 1-1.5 parts of fluorite to form a mixed composition; According to the weight ratio of composition: alumina ball stone: water = 1:1.5:1, the composition, alumina ball stone and water are mixed for ball milling until the balance of the million-hole sieve is less than 0.2%; the raw materials are filtered mud, The mud is practiced and aged for 48 hours, then shaped, dried, glazed, and finally fired at a temperature of 1200-1250°C. The present invention adds zinc oxide and fluorite to the formula for reusing electric porcelain waste to form a low-melting substance with impurities at high temperature, improves sintering performance, and promotes the formation of mullite crystal phase, which not only eliminates the influence of impurities, but also improves Improve the porcelain mechanical strength and hot and cold abrupt change.

Description

technical field [0001] The invention relates to an electric porcelain material, in particular to an electric porcelain material remanufactured by recycling existing electric porcelain wastes and a manufacturing process thereof. Background technique [0002] In the manufacturing process of electric porcelain products, it is inevitable to produce a part of slurry coating mud, which is discharged through the sewer to form waste. The best way to deal with waste is to recycle and reuse, which not only reduces costs, but also increases the added value of production. However, there are two problems in the reuse of electric porcelain waste: 1. During the discharge process, the reduction of ridged raw materials causes a mismatch in the formula; 2. There is the problem of impurities mixed in; adding zinc oxide and Fluorite and impurities form part of the low-melting material, which can promote sintering to improve the impurities in the porcelain.
