[UVLED Sterilization] Sayansi Yodziwika ya UV LED Sterilization Disinfection

Kuwala kwa ultraviolet ndi mawonekedwe amphamvu kwambiri okhala ndi mphamvu zambiri, maso amaliseche sangathe kudziwika. Kutalika kwake ndi kosakwana 400nm, komwe kuli kunja kwa mbali yowonekera ya ultraviolet end, motero imatchedwa kuwala kwa ultraviolet. Ndi mawonekedwe a kutalika kwa mafunde ogawidwa mu UV-A (320nm 400nm), UV-B (275nm 3 2 0 n m), UV-C (2 0 nm 2 7 5 nm), UV-D (100nm 200nm) anayi Gululi, momwe A , B, ndi C, magulu atatu amatchedwanso cheza cha ultraviolet chopha tizilombo. Magulu atatu a A, B, ndi C ali ndi mphamvu yopha tizilombo toyambitsa matenda, makamaka pakuphatikizira bwino kwambiri kwa C band. Lingaliro la kuwala kwa quantum limakhulupirira kuti kuwala ndi mtundu wapadera wa kayendetsedwe ka zinthu. Utali uliwonse wa 253.7nm UV photon uli ndi mphamvu za 4.9EV. Kuphera tizilombo toyambitsa matenda ndi kutsekereza kwa mzere wa UV kumadzi ndi gawo lalikulu kwambiri la mayamwidwe (254nm) a nucleic acid (DNA). DNA akhoza kuyamwa mkulu - mphamvu ultraviolet cheza, chifukwa moyandikana alkali - zochokera dislocation, ndi kupanga pyrimidine dimer; Kukopa kwa Nucleic acid ndi mawu a protein kumabweretsa apoptosis. Pakalipano, kafukufuku amangofufuza kafukufuku wamtundu wa ultraviolet-ray, ndipo UV-LED monga njira yatsopano yophera tizilombo ingakhale yosiyana kwambiri ndi njira yachikhalidwe yophera tizilombo. Chotero. Kuti mumve zambiri, talandiridwa patsamba lovomerezeka http:///show-23-155.html
