Problems solved by technology

As the content of zirconium element in the formula increases, the radioactivity of the product will increase. When it reaches a certain amount, the radioactivity of the product will exceed the standard. Such a formula will not only often have the problem that the radioactivity test cannot meet the standard, but also the surface texture looks very stiff. Not enough smoothness after polishing

Abstract

The invention discloses a pure white polished tile and a production method thereof. The chemical components of raw material components of the tile comprise, by mass, 65-74% of SiO2, 16-21% of Al2O3, 5-8% of alkali metal oxide and / or alkali earth oxide, 0.25% or less of Fe2O3 and 0.1% or less of TiO2, and has an ignition loss of 3-5%. In the invention, desiliconized aluminum powder is fully used to substitute previous zirconium silicate and other zirconium-containing materials, and the polished brick is directly whitened by the selected raw material without adding the zirconium-containing materials, so the whiteness of the polished tile is greatly improved through the desiliconized aluminum powder, whiteness technology requirements are met, and the radioactivity standard exceeding problem of present polished tiles is solved; and high-viscosity bentonite is introduced to substitute parts of ball clay / clay (called mud for short) to increase the whiteness, and the whiteness of the produced polished tile is 60-62 DEG and is suitable for market demands in the ceramic industry. The production method has the advantages of simplicity in operation, easily available raw materials, low cost, strong technology controllability, and realization of production of the 60 DEG pure white polished tile.

Description

technical field [0001] The invention relates to the technical field of tile production, in particular to a pure white polished tile and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards and the awareness of environmental protection in the whole society, the requirements for ceramic tiles are also getting higher and higher. Especially the impact of radioactive problems on nature and human beings. [0003] At present, the whiteness of ultra-white series products on the market is generally 50-55 degrees. Due to the limitation of the whiteness of raw materials, high-ultra-white raw materials are very rare. To improve the whiteness, ceramic companies that produce ultra-white products will add it to the formula. A certain amount of zirconium silicate or raw materials containing zirconium elements; and zirconium elements are the main source of xenobiotic pollution. As the content of zirconium in the formula in...
