Super-white polished brick

Abstract

This invention relates to a ultrawhite polishing brick. According to weight shares the raw materials includes: calcined alumina 5 to 10 shares, burning talcum 10 to 40, ultrawhite ball clay 18 to 25, water washing kaolin 5 to 12, low temperature feldspar 13 to 25, middle and high temperature porcelain sand 10 to 18 shares. The process includes: ball milling, spraying and corning, shaping by quenching, adobe drying and kiln burning. This invention has high whiteness, good thermostability, and avoid zirconium silicate radioactive problem.

Description

technical field

[0001] The invention relates to the technical field of inorganic silicates, specifically to the technical field of ceramic tiles, and more specifically to an ultra-white polished tile. technical background

[0002] Usually, white represents purity and flawlessness, so ultra-white ceramic tile products are often loved by consumers. General ultra-white bricks are made of SiO 2 -Al 2 o 3 -R 2 O as the basic system, plus zirconium silicate whitening, the whiteness is difficult to exceed 58 (standard substance BaSO 4 The whiteness is 100), especially when the amount of zirconium silicate is too much, the radiation index of the green body will increase significantly, causing obvious damage to the human body; the firing temperature will also increase significantly, and the firing cost of the finished product will also increase accordingly.
