Abstract

The invention provides a technique of sanitary ceramic using a composite titanium dioxide opacifier in glaze slurry. The technique adopts the composite titanium dioxide opacifier, phosphate, potash feldspar, quartz, calcite, dolomite, zinc oxide, aluminum oxide, kaoline and a frit as raw materials for preparing opalescent glaze of the ceramic. The sanitary ceramic prepared by the technique has the advantages that: (1) a glaze layer of the prepared sanitary ceramic is tightly combined with a green body; a glaze surface has a good opacifying effect, and is high in whiteness, strong in luster sensation and delicate; (2) the composite titanium dioxide opacifier glaze and the glaze layer of the sanitary ceramic are free from radioactive substances and radioactive radiation and has effects of safety and protection of user health; and (3) the composite titanium dioxide opacifier is lower in cost and price; and phosphate is added into the glaze at the same time to further reduce the use amount of the composite titanium dioxide opacifier, so that the cost of the sanitary ceramic is lowered.

Description

technical field [0001] The invention relates to the technical field of producing sanitary ceramics with a white opacified glaze surface, in particular to a process method for sanitary ceramics using a composite titanium dioxide opacifying agent in glaze slurry. Background technique [0002] Sanitary ceramics refer to glazed ceramic products used in toilets, kitchens, laboratories and other places, also known as sanitary ware. Sinks and tanks etc. Most of the dense glaze layer covered on the surface of sanitary ceramics is white, which has an opacifying effect, and is flat, smooth, delicate, and has a strong sense of luster, which makes the green body covered, sealed and protected, and thus forms a clean, easy-to- Cleaning, no water absorption, no dirt absorption and aesthetic appearance. In addition, special functions such as self-cleaning and antibacterial can also be endowed to ceramic products by adjusting the glaze composition and adding functional additives to the gla...
