     China developed a new anti-UV glass, new products can really prevent ultraviolet radiation on the human body, objects and other hazards, can be widely used in automotive windshields, glass and other anti-aging items, the outlook is very bright.

Currently, many on the market claiming to UV glass, the vast majority of the smear layer on the glass can be opaque coating on the part of the long-wavelength ultraviolet light does have some blocking effect. However, it’s difficult to master the coating, thick transparent visible is poor, thin UV effect is not strong. Research institutions have developed a more advanced anti-UV glass varieties, is added to ordinary titanium silicate glass, vanadium oxide, iron oxide and other metal oxides, and strictly control the melting atmosphere, a system of body UV absorption glass. Such technology represents a substance added to the glass in a new direction, but the metal oxides of UVA to prevent the effect is not very good, and good visual effects products, in many cases do not apply.

We know that UV tanning sunburn are mainly UVA and UVB. The UVA band, which wavelength is 320 ~ 420nm, also was known as the effect of long-wave ultraviolet light spots. It has a strong penetrating power, can penetrate most of the transparent glass and plastic. Sunlight contains UVA can penetrate more than 98% of the ozone layer and the clouds reach the Earth's surface, UVA can reach the skin's dermal layer, destruction of elastic fibers and collagen fibers, our skin tanning and wrinkles and fine lines, loose skin aging, which is medically known as photo-aging. UVB band, wavelength 275 ~ 320nm, most of the skin to absorb a small part to dermal, skin damage is the main band, but can be thick clouds, clothes and glass partially blocked.

Methoxy cinnamate Methyl significant because of UVA absorption, wavelength 200 ~ 400nm UV (mainly UVA, UVB) has the strongest scattering, UV effect is very good. The researchers will add in the p-methoxy cinnamic acid methyl ester glass, products made ​​prominent in the UV effects at the same time, the effect of visible light through very good, very suitable for visible light with the strict requirements of the automobile windshield glass.

Researchers said, Solar radiation in the ultraviolet, is caused by the floor, carpet, furniture, art paintings, curtains, and the main reason many of the aging fabric fading of valuables are also great damage effect, In light of the need to protect the needs of the occasion while there, especially for the museum.
