Problems solved by technology

However, at present, due to the standardization of process equipment and raw materials in China, dry powder making is only applied to small-sized interior wall tiles, and the raw material for 2cm thick porcelain plates with high strength and low water absorption is still wet process, which consumes a lot of energy. High, the waste water and waste gas produced in the milling process will cause serious pollution to the environment
In addition, the formula of the existing 2cm thick porcelain slab blank in the existing wet milling method cannot be directly transferred to the dry milling method, because the existing formula of the 2cm thick porcelain slab blank includes high plasticity clay, and the moisture content of the high plasticity clay is relatively low. High (about 30%), it is difficult to dry and crush by dry milling

Abstract

The invention discloses porcelain plate blank powder. The porcelain plate blank powder is prepared from components in percentage by weight as follows: 45%-60% of potassium-sodium feldspar, 5%-12% of hard high-alumina clay, 30%-45% of kaolin, 1%-2% of talc and 4%-8% of bentonite, and the weight percentage sum of the components is 100%. The porcelain plate blank powder adopts simple composition and can be applied to a dry process for preparation of a porcelain plate blank with the thickness of 2 cm, and the prepared porcelain plate blank has high strength and low water absorption. The invention further discloses a preparation technology of the porcelain plate blank powder. The preparation technology is simple, the energy consumption is low and small amount of wastewater and waste gas is produced.

Description

technical field [0001] The invention relates to the technical field of architectural ceramic tiles, in particular to a porcelain slab body powder and a preparation process thereof. Background technique [0002] The preparation methods of ceramic wall and floor tile powder can be divided into two categories: dry powder making and wet powder making. The wet process is to add water to the raw material in a ball mill to grind it into a slurry with a required fineness, and then spray dry it to make a powder or press filter the slurry, dry it and then make a powder. It has the advantages of simple process, large output, good particle fluidity, and uniform water content, but the tail gas contains a lot of dust. If it is not treated, it will cause serious air pollution and consume a lot of energy. The dry process is to directly grind the raw materials into fine powder, and then granulate the fine powder, which has the advantages of low energy consumption and water saving. In the p...
