Nano TiO2 work for anti-ultraviolet:Nano-TiO2 can absorb both ultraviolet light, but also reflective, scattered ultraviolet light, but also through the visible light, is superior performance, very promising physical shielding type UV protection agent.

Nano-titanium dioxide anti-ultraviolet mechanism: According to the different wavelengths, ultraviolet is divided into short wavelength region 190 ~ 280 nm, medium wave area 280 ~ 320 nm, long wave area 320 ~ 400nm.

 

The short-wave area has the highest ultraviolet energy, but is blocked when it is separated from the ozone layer. Therefore, the damage to the human body is generally in the middle and long wavelength areas. The strong UV resistance of nano-titanium dioxide is due to its high refractive and high light activity. Its anti-ultraviolet ability and its mechanism are related to its particle size.

 

When the particle size is large, the barrier to ultraviolet rays is reflected and scattered, and it is effective for both ultraviolet and medium wavelengths. Sun protection mechanism is a simple cover, is a general physical sunscreen, sunscreen is weak; with the particle size decreases, the light can pass through the nano-titanium dioxide particle surface, the long wave of ultraviolet light reflection, scattering is not obvious, and The absorption of ultraviolet light in the wave area is obviously enhanced.

 

The sunscreen mechanism is to absorb ultraviolet light, the main absorption of ultraviolet light in the wave area.It can be seen that the nano-titanium dioxide on different wavelengths of ultraviolet radiation mechanism is not the same, the long-wave area of the UV block to the main scattering, the UV wave in the wave area to absorb the main.

 

Nano-titanium dioxide in different wavelengths have shown excellent absorption properties, compared with other organic sunscreen, nano-titanium dioxide with non-toxic, stable performance, good effect and so on.Nano-titanium dioxide due to small particle size, large activity, both reflective, scattered ultraviolet light, but also absorb ultraviolet light, which has a stronger ability to block UV.

 

Compared with some of the same dose of organic UV protective agent, HWNANO nano-titanium dioxide in the ultraviolet absorption peak higher, more valuable it is a broad spectrum of shielding agents, unlike organic UV protective agent that only a single UVA or UVB absorption.
