Household ceramic produced by comprehensively utilizing various tailings and manufacturing method thereof

Abstract

The invention discloses a household ceramic manufacturing method. The blank of the household ceramic is prepared from the following raw materials in percentage by weight: 18 to 20 percent of Chengkeng clay tailing, 15 to 17 percent of Guodong china clay tailing, 19 to 22 percent of Tudike kaolin tailing, 16 to 17 percent of feldspar and 24 to 27 percent of clay. The manufacturing method comprises the following steps of: screening the Chengkeng clay tailing, the Guodong china clay tailing and the Tudike kaolin tailing according to classes, removing impurities, crushing, mixing according to a proportion, performing ball milling, sieving, iron removal, pressure filtration, coarse refining, ageing, and vacuum pugging to obtain a blank, drying, and glazing; and firing to obtain the household ceramic finished product. Various tailings are compounded, and the tailings account for 52 to 59 percent of the total mass of the raw materials. The household ceramic has the advantages of low production cost, high finished product ratio, stable structure, lower firing temperature, effective prevention of waste and energy waste, light environmental pollution and suitability for popularization.

Description

technical field [0001] The invention relates to the technical field of ceramic product manufacturing, in particular to a daily-use ceramic produced by comprehensively utilizing various tailings and a manufacturing method thereof. Background technique [0002] my country's production of daily-use ceramics accounts for about 65% of the world, and its annual export volume reaches more than 8 billion pieces, accounting for more than 70% of the world's total exports. However, there are widespread problems such as serious waste of porcelain clay resources, low-grade ceramic products, and high energy consumption in production. Due to the common problems of small-scale enterprises and weak technical force in my country's daily-use ceramics industry, only the purest and highest-grade raw materials are often selected for porcelain clay raw materials, and low-grade raw materials with slightly higher impurities are discarded as tailings, or even discarded. It is used as landfill soil tog...

Problems solved by technology

[0002] The output of daily-use ceramics in my country accounts for about 65% of the world, and the annual export volume reaches more than 8 billion pieces, accounting for more than 70% of the world's total exports. However, there are widespread problems such as serious waste of porcelain clay resources, low-grade ceramic products, and high energy consumption in production.

Due to the common problems of small-scale enterprises and weak technical force in my country's daily-use ceramics industry, only the purest and highest-grade raw materials are often selected for porcelain clay raw materials, and low-grade raw materials with slightly higher impurities are discarded as tailings, or even discarded. It is used as landfill soil together with topsoil, resulting in a great waste of ceramic raw materials, and the accumulation of tailings also causes great pollution to the environment
