Problems solved by technology

[0003] Since as tableware, it is essential to have antibacterial function, the traditional silver-based antibacterial ceramics and titanium-based antibacterial ceramics are the most commonly used, the silver-based antibacterial effect is very good, but the disadvantage is that if silver ions are applied to ceramics and fired at high temperature, The glaze will change color and cause the glaze to be unsightly. For example, if the silver ion content is insufficient, the bactericidal effect is not ideal, and the silver ions will volatilize when fired at high temperature, resulting in poor bacterial control effect; the firing process of titanium-based antibacterial ceramics is also Difficult to control
[0004] In addition, it is also common to use microwave ovens to heat food now, so ceramics used as tableware must be resistant to microwaves. At the same time, attention should be paid to the glaze on the surface of ceramics, which may become a health killer

Abstract

The invention specifically relates to an antibacterial and microwave-resistant ceramic and a manufacturing process thereof, belonging to the technical field of ceramic products. The antibacterial and microwave-resistant ceramics include the following raw materials in parts by mass: 21-27 parts of Guangxi magnesia clay, 12-18 parts of calcined quartz, 7-12 parts of aluminum borate silicon salt, 10-19 parts of potassium feldspar , 6-10 parts of zinc oxide, 1-4 parts of calcined talc, 0.5-1 part of dispersant, 2-4 parts of titanium dioxide, and 1-5 parts of chitin. The ceramic has an antibacterial effect, and the antibacterial rate against Escherichia coli and Staphylococcus aureus is as high as 99%; at the same time, it is resistant to microwaves and can be used for microwave heating without producing harmful substances; It not only guarantees the product quality, but also saves energy and protects the environment.

Description

technical field [0001] The invention belongs to the technical field of ceramic products, and in particular relates to an antibacterial and microwave-resistant ceramic and a manufacturing process thereof. Background technique [0002] When choosing tableware, ceramic ware is the first choice for most families to buy because it has various shapes, fine and smooth, bright colors and easy cleaning compared with glass or plastic ware. [0003] Since as tableware, it is essential to have antibacterial function, the traditional silver-based antibacterial ceramics and titanium-based antibacterial ceramics are the most commonly used, the silver-based antibacterial effect is very good, but the disadvantage is that if silver ions are applied to ceramics and fired at high temperature, The glaze will change color and cause the glaze to be unsightly. For example, if the silver ion content is insufficient, the bactericidal effect is not ideal, and the silver ions will volatilize when fired...
