Problems solved by technology

[0003] However, there are few types of ceramics with antibacterial function. Traditionally, silver-based antibacterial ceramics and titanium-based antibacterial ceramics are the most commonly used. Silver-based antibacterial effects are very good, but the disadvantage is that if silver ions are applied to ceramics and fired at high temperature If the silver ion content is insufficient, the bactericidal effect is not ideal, and the silver ions will volatilize during high-temperature firing, resulting in poor bacterial control effect; the disadvantage of titanium-based antibacterial ceramics is: high-temperature firing Bacteria control effect is poor when controlled, and photocatalysis is needed to sterilize; bacteria control film and ceramics are easy to fall off
