Dongguan LIYI Tester UV Tunnel Sterilizer Machine UV Sterilization Machine

Working Principle:

The ultraviolet sterilization band is mainly between 200 nm and 300nm, among 253.7nm has the strongest sterilization ability. When all kinds of bacteria and viruses in water or air through area (253.7 nm wavelength) exposure to the sun's ultraviolet rays, ultraviolet light penetrates the cell membrane and nucleus of microorganism, destruction of nucleic acids (DNA or RNA) molecular bonds, make its losing the ability to replicate or lose their activity and death, and in the case of without using any chemicals to kill all the bacteria and viruses. Sterilization lamp do not need to be converted to visible light, 100-200 nm wavelength can have very good sterilization effect, this is because the cells of light absorption lines there is a rule, in 100-200 - nm ultraviolet ray has the largest absorption, absorbed the ultraviolet ray in fact role in cellular genetic material or DNA, it plays a allochromatic, ultraviolet photons energy absorbed by the base pairs of DNA, cause mutation genetic material, make the bacteria died instantly or cannot reproduce, achieve the purpose of sterilization.
