Problems solved by technology

Usually, the proportion of transparent material in polycrystalline micropowder is about 25-50%. If the proportion of transparent material is further increased, if it reaches more than 95%, large deformation (especially late deformation), many pinholes and melting holes will occur, and the transparent material will be white. Defects such as low temperature (only about 45 degrees), sensitive hair color, large color difference, low yield, etc.
These problems limit the application of transparent materials in micropowder polished tiles, especially the application of high whiteness transparent materials in polished tiles

Abstract

The present invention relates to one kind of decorating transparent vitrified ceramic tile and its material recipe and production process. The material for the decorating transparent vitrified ceramic tile consists of white stone powder 10-25 wt%, Chaozhou sand 15-30 wt%, Guangxi sand 15-30 wt%, white jade powder 5-25 wt%, Hunan stone powder 15-30 wt%, kaolin 10-20 wt%, black mud 1-10 wt% and M-type flux 0-10 wt%. The production process includes the steps of compounding material, ball milling, color mixing, spray drying, forming, drying, sintering and polishing. The produced ceramic tile is transparent, high white and high bright, and has no radioactivity, relatively high heat expanding coefficient and other advantages.

Description

Technical field: [0001] The present invention relates to a high-white transparent material formula of ice crystal jade full-permeable decorative craft porcelain vitrified brick and a production method of the brick. Background technique: [0002] With the continuous improvement of the technical level of polished tiles, the application range of transparent materials in polished tiles is also expanding. The production technology of ordinary polycrystalline micropowder, that is, micropowder containing transparent material, has been relatively mature, and manufacturers of various sizes have successively launched some products. Generally, the proportion of transparent material in polycrystalline powder is about 25-50%. If the proportion of transparent material is further increased, if it reaches more than 95%, large deformation (especially post-deformation), many pinholes and melting holes will occur, and the transparent material will be white. Defects such as low intensity (only about...
