Ceramic self-cleaning glaze

Abstract

The invention discloses a ceramic self-cleaning glaze. A ground glaze consists of 33 parts of an ultrafine quartz powder, 20 parts of feldspar, 10 parts of wollastonite, 5.5 parts of calcite, 4 parts of dolomite, 3.5 parts of bahrain soil, 6.5 parts of a calcined alumina powder, 2 parts of calcined zinc oxide, 4.5 parts of frit and 13 parts of an ultrafine zirconium silicate powder; an overglaze consists of the components in parts by weight; 38 parts of the ultrafine quartz powder, 24 parts of feldspar, 13 parts of wollastonite, 4 parts of calcite, 3 parts of dolomite, 4.5 parts of bahrain soil, 7 parts of a calcined alumina powder, 1.5 parts of calcined zinc oxide and 4.5 parts of frit; the particle size of the ground glaze is 1-10 microns, and the ground glaze is 0.8-1.2mm in thickness; the particle size of the overglaze is not greater than 10 microns, and the overglaze is 0.2-0.3mm thick; the ground glaze and the overglaze are calcined independently; the start temperature is 145 DEG C, the highest temperature is 1,298 DEG C, and the glazes are cooled to 70-80 DEG C; the calcining time is 12-22 hours. The number of needle holes and the number of cracks on the surface of the ground glaze are small, so that a product is uniform in texture, the surface is fine and bright, and dirt is unlikely to attach.

Description

technical field [0001] The invention relates to a self-cleaning glaze used in ceramic sanitary ware products. Background technique [0002] At present, in the production of sanitary ware, the opacity glaze of 0.6-0.8mm is widely used on the surface of the porcelain body, and it is fired at a high temperature of about 1200 degrees to achieve the brightness of the glazed surface of the product. After a period of use, the glazed product , because the rough pinholes on the surface of the product will cause dirt to adhere, it is very difficult to clean, and at the same time it will breed various germs such as E. coli and Staphylococcus aureus, and long-term contact will cause harm to the human body. Contents of the invention [0003] The purpose of the present invention is to overcome and solve the glaze condition of sanitary ware, and provide a self-cleaning glaze for sanitary ceramic sanitary ware with low production cost. [0004] The technical solution adopted to achieve t...
