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 an ultrawhite polished tile and a preparation method thereof. The ultrawhite polished tile is prepared from chemical components of raw materials in percentage by mass as follows: 65%-74% of SiO2, 16%-23% of Al2O3, 5%-8% of alkali metal oxide and / or alkaline earth metal oxide, smaller than or equal to 0.2% of Fe2O3, smaller than or equal to 0.1% of TiO2 and 3%-5% of loss on ignition. Desiliconized aluminum powder is sufficiently utilized to replace conventional zirconium silicate and other zirconium-containing materials, the polished tile is whitened by directly using the raw materials instead of adding the zirconium-containing materials, accordingly, the whiteness of the polished tile is greatly improved through the desiliconized aluminum powder, the process requirement for whiteness is met, and the problem that the radioactivity of conventional polished tiles is beyond the standard is solved; the whiteness of the prepared polished tile is 70%-72%, and the prepared polished tile meets the market demands of the ceramic industry. The preparation method is simple to operate, raw materials are easy to obtain, the cost is low, the process controllability is high, and the ultrawhite polished tile with the whiteness of 70% can be prepared.

Description

technical field [0001] The invention relates to the technical field of tile production, in particular to an ultra-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 scarce. To improve the whiteness, ceramic companies that produce ultra-white products will be on the formula. A certain amount of chemical raw materials such as zirconium silicate is added, and zirconium is the main source of radiation pollution. As the content of zirconium in the formula increases, the radio...
