Applications:
1.
For antibacterial ceramics, the process is to first add nano titanium dioxide
(DK-TiO2-A15) to the slurry, apply it on the surface of ceramic tile, and
obtain 1cm thick nanometer titanium dioxide film with sterilization performance
after high temperature calcination. product. The product completely kills
surface bacteria under light irradiation; it also has antibacterial properties
under weak light.
2,
nano titanium dioxide (DK-TiO2-A15) under the irradiation of 4W UV lamp and
sunlight as the light source, the sterilization rate is over 99%, and the
degradation rate of formaldehyde is more than 85%.
3.
Nano-TiO2 (DK-TiO2-A15) ceramics have excellent properties for decomposing
organic pollutants.
4.
The nano-titanium dioxide (DK-TiO2-A15) particles are very strong in
combination with the ceramic surface, have strong friction resistance and are
not easy to fall off.
