Hauv qee cov nroj tsuag kev lag luam, xws li biopharmaceuticals, kev lag luam zaub mov, thiab lwm yam, yuav tsum muaj daim ntawv thov thiab tsim cov teeb ci ultraviolet. Hauv kev tsim teeb pom kev zoo ntawm chav huv, ib qho uas tsis tuaj yeem tsis quav ntsej yog seb puas yuav xav txog kev teeb tsa ultraviolet teeb. Ultraviolet sterilization yog nto sterilization. Nws yog ntsiag to, tsis muaj tshuaj lom thiab tsis muaj residue thaum lub sij hawm ua kom tsis muaj menyuam. Nws yog kev lag luam, yoog raws thiab yooj yim, yog li nws muaj ntau yam kev siv. Nws tuaj yeem siv rau hauv cov chav tsis muaj menyuam, chav tsiaj thiab cov chaw soj nstuam uas yuav tsum tau ua kom tsis muaj menyuam hauv kev ntim khoom hauv kev lag luam tshuaj, thiab hauv kev ntim khoom thiab ntim cov kev cob qhia hauv kev lag luam zaub mov; Hais txog kev kho mob thiab kev noj qab haus huv, nws tuaj yeem siv rau hauv chav ua haujlwm, pawg ntseeg tshwj xeeb thiab lwm lub sijhawm. Nws tuaj yeem txiav txim siab raws li tus tswv xav tau seb puas yuav teeb lub teeb ultraviolet.
1. Piv nrog rau lwm txoj kev xws li cua sov kom tsis muaj menyuam, ozone sterilization, hluav taws xob sterilization, thiab tshuaj sterilization, ultraviolet sterilization muaj nws tus kheej zoo:
ib. Ultraviolet rays muaj txiaj ntsig zoo rau txhua hom kab mob thiab yog qhov dav-spectrum sterilization ntsuas.
b. Nws yuav luag tsis muaj qhov cuam tshuam rau cov khoom siv kom tsis muaj menyuam (cov khoom yuav tsum tau irradiated).
c. Nws tuaj yeem ua kom tsis muaj menyuam tsis tu ncua thiab tuaj yeem ua kom tsis muaj menyuam nyob rau hauv lub xub ntiag ntawm cov neeg ua haujlwm.
d. Cov cuab yeej siv qis qis, cov nqi khiav lag luam tsawg, thiab siv tau yooj yim.
2. Cov nyhuv bactericidal ntawm ultraviolet lub teeb:
Cov kab mob yog ib hom kab mob. Cov kab mob muaj cov nucleic acids. Tom qab nqus cov hluav taws xob hluav taws xob ntawm ultraviolet irradiation, cov nucleic acids yuav ua rau photochemical puas, yog li tua cov kab mob. Lub teeb ultraviolet yog qhov pom tsis pom hluav taws xob nrog lub wavelength luv dua li pom lub teeb violet, nrog lub wavelength ntawm 136 ~ 390nm. Ntawm lawv, ultraviolet rays nrog lub wavelength ntawm 253.7nm yog cov kab mob bactericidal heev. Cov teeb pom kev zoo yog raws li qhov no thiab tsim cov kab hluav taws xob ultraviolet ntawm 253.7nm. Qhov siab tshaj plaws hluav taws xob nqus wavelength ntawm nucleic acids yog 250 ~ 260nm, yog li ultraviolet germicidal teeb muaj qee yam kab mob bactericidal. Txawm li cas los xij, lub peev xwm nkag mus ntawm ultraviolet rays rau cov khoom siv feem ntau yog qhov tsis muaj zog, thiab nws tsuas yog siv tau los ua kom tsis muaj menyuam ntawm cov khoom, thiab tsis muaj cov nyhuv sterilizing ntawm qhov chaw uas tsis raug. Rau kev ua kom tsis muaj menyuam thiab lwm yam khoom, txhua qhov chaw ntawm sab saud, qis, sab laug, thiab sab xis yuav tsum tau irradiated, thiab cov nyhuv sterilization ntawm ultraviolet rays tsis tuaj yeem khaws cia rau lub sijhawm ntev, yog li kev ua kom tsis muaj menyuam yuav tsum tau ua tsis tu ncua raws li qhov xwm txheej tshwj xeeb.
3. Radiant zog thiab sterilization nyhuv:
Cov hluav taws xob tso zis muaj peev xwm sib txawv nrog qhov kub, av noo, cua ceev thiab lwm yam ntawm ib puag ncig uas nws siv. Thaum lub ambient kub yog tsawg, cov zis muaj peev xwm kuj tsis tshua muaj. Raws li cov av noo nce, nws cov nyhuv sterilization kuj yuav txo. UV teeb feem ntau yog tsim los ntawm cov av noo nyob ze rau 60%. Thaum cov av noo nyob hauv tsev nce, qhov nyiaj irradiation yuav tsum tau nce ntxiv vim tias cov nyhuv sterilization txo. Piv txwv li, thaum cov av noo yog 70%, 80%, thiab 90%, thiaj li ua tiav cov nyhuv kom tsis muaj menyuam, tus nqi hluav taws xob yuav tsum tau nce 50%, 80%, thiab 90% raws li. Cua ceev kuj cuam tshuam cov zis muaj peev xwm. Tsis tas li ntawd, txij li cov kab mob bactericidal ntawm lub teeb ultraviolet sib txawv nrog cov kab mob sib txawv, tus nqi ntawm ultraviolet irradiation yuav tsum sib txawv rau cov kab mob sib txawv. Piv txwv li, tus nqi ntawm irradiation siv los tua cov fungi yog 40 mus rau 50 npaug ntau dua li siv los tua cov kab mob. Yog li ntawd, thaum xav txog kev ua kom tsis muaj menyuam ntawm ultraviolet germicidal teeb, qhov cuam tshuam ntawm kev teeb tsa qhov siab tsis tuaj yeem tsis quav ntsej. Lub zog sterilizing ntawm ultraviolet teeb decays nrog lub sij hawm. Lub zog tso zis ntawm 100b yog coj raws li lub zog ntsuas, thiab lub sijhawm siv ntawm lub teeb ultraviolet mus rau 70% ntawm lub zog ntsuas yog coj raws li lub neej nruab nrab. Thaum lub sij hawm siv ntawm lub teeb ultraviolet ntau tshaj qhov nruab nrab lub neej, qhov kev xav tau tsis tuaj yeem ua tiav thiab yuav tsum tau hloov lub sijhawm no. Feem ntau, lub neej nruab nrab ntawm cov teeb hluav taws xob hauv tsev yog 2000h. Cov nyhuv sterilizing ntawm ultraviolet rays yog txiav txim los ntawm nws cov nqi hluav taws xob (cov hluav taws xob hluav taws xob ntawm ultraviolet germicidal teeb tseem tuaj yeem hu ua cov kab hluav taws xob kom tsis muaj menyuam), thiab cov hluav taws xob hluav taws xob ib txwm sib npaug ntawm cov hluav taws xob siv hluav taws xob sib npaug los ntawm lub sijhawm hluav taws xob, yog li nws yuav tsum. ua kom cov nyhuv hluav taws xob ntau ntxiv, nws yog ib qho tsim nyog yuav tsum tau ua kom cov hluav taws xob siv hluav taws xob ntau ntxiv los yog ncua sij hawm hluav taws xob.
