The ultraviolet ray disinfects the principle and knowledges
From:Internet  Date:2006-08-09
Know to all, because of the wave-length of the light dissimilarity, produce red,
Huang, orange, green, green, blue and purple seven color lights, the ultraviolet
ray is a kind of form of the ray, is a kind of light of high energy.But the wave-length
of the purple outside light is from the 40 nms-400 nms, the wave-length is too
short, so the person's naked eye is hard to see of. is divided into the wave band
of A, wave band of B, wave band of C and the vacuum ultraviolet rays according
to the wave-length. the wave-length of the wave band of C for the 200 nm £ 275
nms. the water disinfects what to use is a wave band ultraviolet ray of C.
The ultraviolet ray is the 240 nms in the wave-length- The 280 nm scope has
most to disinfect the effect, particularly in wave-length for 253.7 nms ultraviolet
ray disinfect function the most strongly. ultraviolet ray of a C( C- BAQND)
have tremendous effect to the human body harmful germs or viruses towards destroy.
it disinfect principle is pass the ultraviolet ray to the unicellular microorganisms,
such as cell and virus...etc. of irradiation, the structure that to break its
life axis DNA( go to the oxygen to check the sugar nucleic acid), make constitute
should the microbial protein can't become, making it die or lose the ability
of breed immediately. the general ultraviolet ray can attain the result of put
out the germ within 1-2 seconds. currently have already prove, the ultraviolet
ray can kill to put out the germs, fungi, virus and the list afterbirth. in
fact, all microorganisms are to the ultraviolet rays all very sensitive, so
the ultraviolet ray used for processing of water's is very superior.
