Problems solved by technology

However, due to the current glazed tiles still have problems such as poor color development, many bubbles, and poor gloss, these problems can no longer meet the needs of consumers.
At the same time, there is an increasing phenomenon of rare earth tailings in my country, which has caused soil erosion and environmental pollution. Therefore, how to rationally utilize rare earth tailings has become a relatively urgent social problem.

Abstract

The invention discloses a method for preparing super-flat polished ceramic tiles by utilizing rare-earth tailings. A double-layered blank body, a reasonable blank body formula and grain composition are adopted to maximally use the rare-earth tailings as main production raw materials of a blank body; meanwhile, gas in the blank body can be discharged as much as possible through improving an initial smelting temperature of a ground glaze layer; wear-resisting fritted glaze is adopted in a surface glaze layer so that the smelting temperature of a glaze surface is reduced and the wear-resisting rigidity of the glaze surface is also guaranteed; finally, a high-temperature heat-insulation manner is used for improving the strength of a brick body and the flatness of the glaze surface. The rare-earth tailings are used as the main raw material and the wear-resisting fritted glaze is adopted, so that the resource utilization of wastes is effectively improved; the firing temperature is greatly reduced, the firing period is shortened and the production cost is remarkably reduced, so that the method has wide market prospect.

Description

technical field [0001] The invention belongs to the field of inorganic non-metallic materials (ceramics), and in particular relates to a method for preparing ultra-flat glazed ceramic tiles by using rare earth tailings. Background technique [0002] Fully glazed ceramic tiles are the products of traditional polished tiles after glazing on the surface. Compared with traditional polished tiles, fully glazed ceramic tiles not only have good stain resistance, but also have richer patterns and colors. After the tiles are fired at high temperature, It has the characteristics of bright colors, various designs and colors, and natural textures. Since ink-jet printing technology and mirror full-polishing technology were widely used in the production of architectural ceramics in 2010, the performance of fully-polished glazed ceramic tiles has been perfectly upgraded. The product combines the advantages of polished tiles, antique tiles, and tiles. The glossiness and porcelain hardness ...
