The function of titanium dioxide that you don't know

Comments · 41 Views

Nanoscale titanium dioxide is also called titanium dioxide. The diameter is less than 100 nanometers, and the appearance of the product is white loose powder. It has anti-thread, antibacterial, self-cleaning and anti-aging properties, and can be used in cosmetics, functional fibers, plasti

1. Nature

Nano-TiO2 has very valuable optical properties, and has shown bright prospects in the automotive industry and many fields. Nano-TiO2 also has high chemical stability, thermal stability, super-hydrophilicity, and non-migration, so it is widely used in anti-ultraviolet materials, textiles, photocatalytic catalysts, self-cleaning glass, sunscreen, coatings, inks, Food packaging materials, paper industry, aerospace industry, lithium batteries.

 

2. Function

(1) Anti-ultraviolet function

Nano-TiO2 can not only absorb ultraviolet rays, but also reflect and scatter ultraviolet rays, and can also pass through visible light. It is a physical shielding ultraviolet protective agent with superior performance and great development prospects. Due to its small particle size and high activity, nano-titanium dioxide can not only reflect and scatter ultraviolet rays, but also absorb ultraviolet rays, so it has a stronger ability to block ultraviolet rays.

Nano-titanium dioxide exhibits excellent absorption properties in different wavelength regions. Compared with other organic sunscreens, nano-titanium dioxide has the characteristics of non-toxicity, stable performance and good effect. Japan's Shiseido uses 10-100nm nano-titanium dioxide as a sunscreen ingredient to add to lipsticks and face creams, and its sunscreen factor can be greater than SPF11-19.

 

Due to its small particle size and high activity, nano-titanium dioxide can not only reflect and scatter ultraviolet rays, but also absorb ultraviolet rays, so it has a stronger ability to block ultraviolet rays. Compared with some organic UV protection agents with the same dose, VK-T02 nano-titanium dioxide has a higher absorption peak in the ultraviolet region, and what is more valuable is that it is also a broad-spectrum shielding agent, unlike organic UV protection agents that only have a single UVA or UVB protection. There is absorption. It can also pass through visible light, and when added to cosmetics, the skin whiteness is natural, unlike pigment-grade TiO2, which cannot pass through visible light, resulting in an unnatural pale color on the user's face.

 

(2) Self-cleaning function

TiO2 film is super-hydrophilic and super-permanent under light, so it has anti-fog function. For example, if a layer of titanium oxide film is coated on the rearview mirror of a car, even if the moisture or water vapor in the air condenses, the condensed water will not form a single water droplet, but will form a water film that spreads evenly on the surface, so the surface will not occur. Fog that scatters light. When rainwater washes over, the rainwater attached to the surface will quickly spread into a uniform water film, so that water droplets that scatter the line of sight will not be formed, so that the surface of the rearview mirror maintains its original brightness and improves driving safety.

 

Nano-TiO2 has strong "super-hydrophilicity", and it is not easy to form water droplets on its surface, and nano-TiO2 can act on hydrocarbons under visible light irradiation. Using such an effect, a layer of nano-TiO2 thin layer can be coated on the surface of glass, ceramics and ceramic tiles, and the organic pollutants adsorbed on the surface of titanium oxide can be decomposed into CO2 and O2 by using the photocatalytic reaction of titanium oxide. Inorganic substances can be washed away by rainwater together, so as to realize the self-cleaning function.
