High-whiteness pure color full-body polishing brick, and production method and application thereof

Abstract

The invention discloses a high-whiteness pure color full-body polishing brick, and a production method and application thereof. The polishing brick is produced by sintering 20 to 30 mass percent of feldspar, 10 to 28 mass percent of high-temperature sand, 20 to 27 mass percent of high-white clay, 0 to 12 mass percent of quartz sand, 10 to 20 mass percent of aluminum powder, 8 to 18 mass percent of calcined talcpowder, 0.5 mass percent of sodium tripolyphosphate and 0.1 to 0.15 percent of methylcellulose at the temperature of 1,180 DEG C for 45 minutes. According to the high-whiteness pure color full-body polishing brick, the whiteness is high (which is 68 to 75 degrees), the radioactivity is close to zero radiation, the water absorption rate is low and is less than 0.1 percent, and the anti-pollution capacity reaches 4 levels; the polishing brick is sintered quickly at low temperature during production, so that the production cost is reduced substantially, and energy conservation and emission reduction are achieved really; and the using amount of calcium oxide and magnesium oxide which serve as raw materials is reduced as far as possible in a formula, and the production defects of poor polishing degree of the sintered brick, narrow sintering range and the like due to a formula in which a large amount of calcium and a large amount of magnesium are required are solved.

Description

technical field [0001] The invention belongs to the field of ceramic building materials, and in particular relates to a ceramic brick, in particular to a high-whiteness pure-color full-body polished brick and its production method and application. Background technique [0002] The whiteness of high-white pure-color polished tiles is much higher than that of ordinary ceramic tiles. Its appearance is white and flawless, soft and elegant. However, the ultra-white bricks currently on the market are mainly through the introduction of zirconium silicate (a chemical raw material with radioactive substances) into the raw material formula of ceramic tiles to improve the whiteness of ceramic tiles, so as to produce ultra-white bricks It will cause a certain degree of harm to human health and the environment; in addition, there is another way to increase the whiteness of ceramic tiles by glazing the tile surface, but the wear resistance of glazed tiles is relatively poor. Once the glaz...

AI Technical Summary

Problems solved by technology

[0005] In view of the shortcomings and problems of the existing ceramic tiles such as low whiteness, radioactive hazards caused by the use of zirconium silicate, poor wear resistance of glazed tiles, low luminosity and poor antifouling of high-magnesia ceramic tiles, and difficulty in mass production, the primary purpose of the present invention is to It is to provide a non-radioactive high-white solid-color whole-body polished tile

[0006] Aiming at the problems of high firing temperature and long firing time in the production of existing ceramic tiles, another object of the present invention is to provide a production method for the above-mentioned high-whiteness solid-color full-body polished tiles, the firing temperature of which is lowered to below 1180°C, The completion time is shortened to less than 45 minutes
