Problems solved by technology

[0003] The antibacterial ceramics circulating in the market have various usage restrictions. First, the firing temperature is low, and the lead and cadmium content of the ceramics exceeds the standard. It is only suitable for use on toilet tiles, etc., and is not suitable for use on tableware; second, the firing temperature and time are sufficient. However, the antibacterial material is burned and lost, and the antibacterial effect is not significant; 3. After the ceramic tableware is fired, the color of the glaze changes, or the expected setting cannot be achieved. Compared with ordinary ceramics, there is an obvious color difference in appearance; 4. The surface of bone china cannot form a glass mirror effect and is whitish, which affects the appearance

Abstract

The invention relates to an antibacterial ceramic manufacturing process, which comprises: (a) blending glaze powder; (b) taking the glaze powder, and adding an antibacterial material to form a mixture, such that the glaze powder accounts for 94-97% of the total weight of the mixture; (c) stirring the mixture; (d) carrying out ball milling on the mixture; (e) screening the mixture through a 325 mesh sieve mesh to obtain particles having a particle size of less than or equal to 325 mesh so as to obtain antibacterial glaze powder; (f) adding the antibacterial glaze powder to water, and stirring to obtain antibacterial glaze water; (g) spraying a porcelain billet body with the antibacterial glaze water; and (h) placing the porcelain billet body treated in the step (g) in a 1050-1150 DEG C kiln, and firing. According to the present invention, the product has advantages of high antibacterial effect, long service life and no influence on appearance after addition; and the process has advantages of simple production steps and high yield.

Description

technical field [0001] The invention belongs to the field of ceramic manufacturing, in particular to a manufacturing process of antibacterial ceramics. Background technique [0002] Ceramic products with antibacterial function, which is a new type of functional ceramics that add inorganic antibacterial agents during the production process of ceramic products, so that the surface of the ceramics has antibacterial effects. Antibacterial bone china refers to bone china with antibacterial effect. Antibacterial bone china can continuously inhibit or kill microorganisms such as bacteria during use. [0003] The antibacterial ceramics circulating in the market have various usage restrictions. First, the firing temperature is low, and the lead and cadmium content of the ceramics exceeds the standard. It is only suitable for use on toilet tiles, etc., and is not suitable for use on tableware; second, the firing temperature and time are sufficient. However, the antibacterial materia...
