Problems solved by technology

The crystallization range of crystalline glaze is very narrow, and the firing conditions are harsh. It is necessary to strictly control the firing heating rate and holding time, that is, the requirements for mastering the firing curve are very strict. For example, the firing temperature of traditional crystalline glaze generally reaches 1350°C. The firing cycle is 14-16 hours

Abstract

The invention discloses crystalline glaze for sanitary ceramic sanitary ware and a preparation process thereof. Proceeded from a process formula, the invention provides novel crystal glaze which meets the requirements of modern ceramic sanitary ware. The crystal glaze is few in type of raw materials required and wide in source and is beneficial for effectively controlling the production cost. The crystalline glaze for sanitary ceramic sanitary ware disclosed by the invention is simple in preparation process. The sintering temperature of the crystalline glaze is controlled at 1170-1230 DEG C, the sintering period is 13-15 hours, the complex process and unique sintering system of crystalline glaze are broken through, and the crystalline glaze for sanitary ceramic sanitary ware is sintered at one time. The crystalline glaze for sanitary ceramic sanitary war is strong in operability and beneficial for energy conservation and environmental protection, and the sintering cost is lowered.

Description

technical field [0001] The invention belongs to the technical field of crystalline glaze, and in particular relates to a crystalline glaze for sanitary ceramics and a preparation process thereof. Background technique [0002] Crystalline glaze is a highly decorative artistic glaze, which enjoys a wide reputation for its unique artistic style and is quite favored by consumers. In recent years, many ceramic production areas in my country have successfully carried out trial production of crystalline glazes, and widely tested crystalline glaze decorations on display porcelain, daily utensils, and wall and floor tiles, and achieved gratifying results. However, the development of crystalline glazes for sanitary ware is still rare at present. The main reason is that the sanitary ceramics used as sanitary facilities have complex structures and different thicknesses. The development of crystalline glazes on sanitary ceramics is prone to deformation and deformation after firing. Defe...
