Function of nano titanium dioxide (1)

1. Bactericidal function

Self dispersed nano titanium oxide manufacturers to explain to you, in the light of ultraviolet under the effect of long-term sterilization. The results showed that anatase nano-TiO2 with the concentration of 0.1mg/cm3 could kill the malignant HeLa cells, and with the increase of the amount of superoxide dismutase (SOD), the efficiency of photocatalytic killing cancer cells was also improved. The killing rates of Bacillus subtilis var. niger spores, Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, Salmonella, Cladosporium odontogenes and Aspergillus were all above 98%. The advanced treatment of tap water with TiO2 photocatalysis oxidation can greatly reduce the number of bacteria in the water, and there is no mutagenic effect after drinking, reaching the standard of safe drinking water; adding nano-TiO2 into the coating can produce sterilization Anti fouling, deodorizing and self-cleaning antibacterial antifouling coating can be used in hospital wards, operating rooms, family toilets and other places where bacteria are dense and easy to breed. It can purify the air, prevent infection, deodorize and deodorize. Can effectively kill and other harmful bacteria.

2. Photocatalytic function

The results show that TiO2 can be activated by ultraviolet light or sunlight to form free radicals with high catalytic activity, which can catalyze and photodegradate formaldehyde and some inorganic substances attached to the surface of objects. It can purify indoor air.

3. Anti fog and self-cleaning function

TiO2 film has super hydrophilicity under light, so it has antifogging function. If a layer of titanium oxide film is coated on the rearview mirror of the car, even if the moisture or steam in the air condenses, the condensed water will not form a single water drop, but form a water film and spread evenly on the surface, so there will be no light scattering fog on the surface. When there is rain, the rainwater attached to the surface will quickly spread to form a uniform water film, so as to avoid the formation of water droplets that can disperse the line of sight, keep the original brightness of the rearview mirror surface, and improve the safety of driving.
