High-whiteness ceramic tile and preparation method thereof
The invention provides a high-whiteness ceramic tile and a preparation method thereof. The preparation method comprises the following steps: preparing raw materials, performing wet-process ball milling, adding water to dilute, magnetically separating, sieving, concentrating and regulating concentration, spray-drying and pelletizing, forming, drying, applying glaze to a glazed brick (canceled for an unglazed brick), sintering, polishing and cutting, inspecting and packaging. By adopting the novel process, the magnetically separating effect of a magnetically separating procedure is greatly improved, the content of magnetic substances in the base body is greatly reduced, and the sintering whiteness of the base body is greatly increased. After a novel process is adopted, the iron content in a base body can be reduced by 0.3-1%, and the base body sintering whiteness is greatly increased by 10-40 degrees in comparison that before magnetically separating; a low-price argillaceous sand stone raw material which is high in iron content and low in sintering whiteness can be adopted in the formula of the ceramic base body to replace raw materials with low iron content and high whiteness of each current manufacturer to produce the base body with whiteness reaching the whiteness required by a high-grade wall and floor tiles, and a ceramic product, so that the base body formula cost is greatly reduced.
