Anatase titanium dioxide is used in paintings
1. Play a bactericidal effect
Experiments have shown that anatase nano-TiO2 at a concentration of 0.1mg/cm3 can completely kill malignant HeLa cells, and it can kill Bacillus subtilis niger spores, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella, Mycobacterium and The killing rate of Aspergillus also reached more than 98%.
Adding nano-TiO2 to coatings can prepare antibacterial and antifouling coatings, which can be used in places where bacteria are dense and easy to multiply, such as hospital wards, operating rooms and family bathrooms, to prevent infection, deodorize and deodorize.

2. Make the paint have sunscreen and anti-aging properties
The strong anti-ultraviolet ability of titanium dioxide is due to its high refractive index and high optical activity. The blocking of ultraviolet rays in the long-wave region is mainly scattering, and the blocking of ultraviolet rays in the medium-wave region is mainly absorption.
Due to its small particle size and high activity, nano-scale titanium dioxide can not only reflect and scatter ultraviolet rays, but also absorb ultraviolet rays, so that it has a stronger blocking ability to ultraviolet rays.
The addition of nano-titanium oxide makes the coating have sunscreen and anti-aging properties.

3. Catalytic purification
Anatase nano-titania liquid has high catalytic activity, and uses sunlight to effectively decompose organic compounds such as formaldehyde, toluene, ammonia, TVOC, etc. into CO2 and H2O, making the pollutants in discrete states easy to clean.
