Product Details

Introduction:

This type of Nano TiO2 is white fluffy powder, with small particle size, large specific surface area, high photocatalytic activity, photochemical stability and other characteristics. Anatase nano-titanium dioxide (T04) with special treatment has strong photocatalytic and antibacterial properties under light irradiation of less than 400 nm, and can be used in the field of antibacterial ceramics.

Product application:

1. For antibacterial ceramics, Nano TiO2 (T04) slurry was prepared by adding water to the surface of ceramic tiles. After high temperature forging, Nano TiO2 film with bactericidal properties of 1 cm thick was obtained. The product can completely kill surface bacteria under light irradiation, and has antibacterial properties under weak light.

2. Under the irradiation of 4W ultraviolet lamp and sunlight, the sterilization rate of Nano TiO2 (T04) is over 99%, and the degradation rate of formaldehyde is over 85%.

3, Nano TiO2 (T04) ceramics have excellent performance in decomposing organic pollutants.

4. Nano TiO2 (T04) particles and ceramic surface bond very firmly, with strong friction resistance, not easy to fall off.
