Raws li cov teebmeem lom neeg thiab cov kab hluav taws xob ultraviolet, plaub pawg tau muab faib raws li lub wavelength:
1. UVA band wavelength 320 ~ 400nm tseem hu ua ntev-yoj dub qhov chaw nyhuv. Ultraviolet muaj zog nkag tau lub zog. Nws nkag mus rau feem ntau pob tshab iav thiab yas. Lub hnub ci muaj qhov ntev-yoj ultraviolet rays. Ntau tshaj 98% tuaj yeem nkag mus rau txheej ozone thiab huab cua kom ncav cuag lub ntiaj teb. UVA nce mus txog txheej dermis ntawm daim tawv nqaij. Ua kom cov elastic fibers thiab collagen fibers. Peb daim tawv nqaij yog tanned. 360nm wavelength UVA ultraviolet rays ua raws li phototaxis teb nkhaus ntawm kab. Ua kab ntxiab 300-420nm wavelength UVA ultraviolet rays dhau los ntawm kev txiav tawm tag nrho lub teeb. Qhov tshwj xeeb xim iav raj tsuas radiates 365nm ze ntawm lub teeb ultraviolet. Siv rau hauv kev txheeb xyuas ore, theem kho kom zoo nkauj, kuaj xyuas nyiaj thiab lwm qhov chaw.
2. UVB band wavelength 275 ~ 320nm tseem hu ua yoj erythema nyhuv. Ultraviolet rays thiab lwm yam luv luv wavelengths yuav absorbed los ntawm cov iav pob tshab. Hnub ci muaj nthwv dej. Feem ntau ntawm ultraviolet rays yog absorbed los ntawm ozone txheej. Tsuas yog 2% tuaj yeem ncav cuag lub ntiaj teb. Tshwj xeeb hauv cov rooj sib tham lub caij ntuj sov thiab yav tav su. Muaj zog UVB ultraviolet rays muaj cov nyhuv erythema rau tib neeg lub cev. Nws tuaj yeem txhawb cov metabolism hauv cov zaub mov thiab tsim cov vitamin D hauv lub cev. Lub sij hawm ntev los yog ntau dhau yuav ua rau daim tawv nqaij tan thiab ua rau liab thiab tev. ) Thiab ua los ntawm phosphor ze li ntawm 300nm ncov.
3. UVC band wavelength yog 100 ~ 275nm, tseem hu ua luv-yoj sterilization. Lub peev xwm nkag mus rau ultraviolet tsis muaj zog. Nws tsis tuaj yeem nkag mus rau feem ntau ntawm cov iav pob tshab thiab yas. Tshav ntuj muaj luv-yoj ultraviolet rays. Nws yuav luag tag absorbed los ntawm ozone txheej. Luv-yoj ultraviolet rays yog teeb meem rau tib neeg lub cev. Kev siv hluav taws xob ntau kuj tuaj yeem ua rau cov tawv nqaij mob qog noj ntshav ultraviolet germicidal teeb kom emit UVC luv-yoj ultraviolet rays.
4. UVD band wavelength tsawg dua 100nm, kuj hu ua lub tshuab nqus tsev ultraviolet.
5. Lub hauv paus ntsiab lus ntawm ultraviolet sterilization:
Ultraviolet sterilization rhuav tshem thiab hloov cov qauv ntawm microbial DNA (deoxyribonucleic acid) los ntawm hluav taws xob ultraviolet, kom cov kab mob tuag tam sim ntawd lossis tuaj yeem tsim dua tshiab. Nws muaj cov nyhuv germicidal. UVC ultraviolet rays tau yooj yim absorbed los ntawm biological DNA vim C-band ultraviolet rays, tshwj xeeb tshaj yog nyob ib ncig ntawm 253.7nm.
Ultraviolet sterilization yog ib txoj kev siv tshuaj tua kab mob hauv lub cev nkaus xwb. Nws muaj qhov zoo ntawm qhov yooj yim thiab yooj yim, dav-spectrum, high-efficiency, tsis muaj kev ua qias tuaj nruab nrab, yooj yim tswj thiab automation, thiab lwm yam. Nrog rau kev qhia txog ntau yam tshiab tsim ultraviolet teeb, daim ntawv thov ntau yam ntawm ultraviolet sterilization kuj tau txuas ntxiv nthuav dav.
