Problems solved by technology

Among them: the first kind of antibacterial ceramics, because the antibacterial material is directly added to the ceramic tile body or glaze and fired, and its antibacterial active ingredients are coated in the body or glaze, its antibacterial effect will be greatly reduced
The second antibacterial material is sprayed on the surface of ceramic tiles and then fired. After high-temperature heat treatment, the structure of the antibacterial material is destroyed, and the antibacterial effect is significantly reduced. A certain amount of antibacterial material is attached to the surface of ceramic tiles. During high-temperature heat treatment, it is easy to react with the glaze surface and affect the surface decoration. Effect
The third type adopts low-temperature heat treatment. The antibacterial layer has weak bonding force with the glaze surface. In practical application, the antibacterial layer is easy to fall off, and the antibacterial durability is poor.
However, the above-mentioned scheme mainly has the following problems. First, zinc oxide or silver oxide is used as the antibacterial material in the antibacterial and antifouling liquid adopted in the prior art. Or silver ion salt solution, in the process of washing, it is easy to wash off the antibacterial material, resulting in poor antibacterial persistence
