COV HAUJ LWM THIAB COV TEJ YAM NTAWM LUB TEEB ULTRAVIOLET HAUV CHAW ZAUB MOV HUV SI

Hauv qee lub Hoobkas kev lag luam, xws li biopharmaceuticals, kev lag luam zaub mov, thiab lwm yam, daim ntawv thov thiab tsim cov teeb ultraviolet yog qhov yuav tsum tau ua. 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 cov teeb ultraviolet. Ultraviolet sterilization yog kev sterilization ntawm qhov chaw. Nws yog ntsiag to, tsis muaj tshuaj lom thiab tsis muaj cov khoom seem thaum lub sijhawm sterilization. Nws yog kev lag luam pheej yig, yoog tau thiab yooj yim, yog li nws muaj ntau yam kev siv. Nws tuaj yeem siv rau hauv cov chav sterilized, chav tsiaj thiab chaw soj nstuam uas yuav tsum tau sterilized hauv cov chaw ntim khoom hauv kev lag luam tshuaj, thiab hauv cov chaw ntim khoom thiab sau hauv kev lag luam zaub mov; Txog kev kho mob thiab kev noj qab haus huv, nws tuaj yeem siv rau hauv chav ua haujlwm, chav tshwj xeeb thiab lwm yam xwm txheej. Nws tuaj yeem txiav txim siab raws li tus tswv xav tau seb puas yuav teeb tsa cov teeb ultraviolet.

1. Piv nrog rau lwm txoj kev xws li kev ua kom sov, kev ua kom ozone, kev ua kom hluav taws xob, thiab kev ua kom tshuaj lom neeg, kev ua kom ultraviolet muaj nws qhov zoo:

a. Cov teeb ultraviolet muaj txiaj ntsig zoo rau txhua hom kab mob thiab yog kev ntsuas kom tsis muaj kab mob dav dav.

b. Nws yuav luag tsis muaj dab tsi cuam tshuam rau cov khoom siv tua kab mob (khoom siv uas yuav tsum tau irradiated).

c. Nws tuaj yeem raug sterilized tas li thiab kuj tuaj yeem raug sterilized nyob rau hauv lub xub ntiag ntawm cov neeg ua haujlwm.

d. Kev nqis peev tsawg rau cov khoom siv, cov nqi khiav lag luam tsawg, thiab yooj yim siv.

2. Cov nyhuv tua kab mob ntawm lub teeb ultraviolet:

Cov kab mob yog ib hom kab mob me me. Cov kab mob me me muaj cov kua qaub nucleic. Tom qab nqus lub zog hluav taws xob ntawm ultraviolet irradiation, cov kua qaub nucleic yuav ua rau muaj kev puas tsuaj photochemical, yog li tua cov kab mob me me. Lub teeb ultraviolet yog lub zog hluav taws xob tsis pom nrog lub wavelength luv dua li lub teeb violet pom, nrog rau qhov wavelength ntawm 136 ~ 390 nm. Ntawm lawv, cov teeb ultraviolet nrog qhov wavelength ntawm 253.7 nm yog cov kab mob tua kab mob heev. Cov teeb germicidal yog raws li qhov no thiab tsim cov teeb ultraviolet ntawm 253.7 nm. Qhov siab tshaj plaws ntawm kev nqus hluav taws xob wavelength ntawm nucleic acids yog 250 ~ 260 nm, yog li cov teeb ultraviolet germicidal muaj qee yam kev ua haujlwm bactericidal. Txawm li cas los xij, lub peev xwm nkag mus ntawm cov teeb ultraviolet rau feem ntau cov tshuaj tsis muaj zog heev, thiab nws tsuas yog siv tau los tua cov khoom ntawm qhov chaw, thiab tsis muaj kev ua kom tsis muaj kab mob rau cov khoom uas tsis raug. Rau kev ua kom cov khoom siv thiab lwm yam khoom tsis muaj kab mob, txhua qhov ntawm sab saud, sab qis, sab laug, thiab sab xis yuav tsum tau irradiated, thiab cov nyhuv ntawm kev ua kom tsis muaj kab mob ntawm cov duab ultraviolet tsis tuaj yeem khaws cia ntev, yog li kev ua kom tsis muaj kab mob yuav tsum tau ua tsis tu ncua raws li qhov xwm txheej tshwj xeeb.

3. Lub zog radiant thiab cov nyhuv sterilization:

Lub peev xwm tso tawm hluav taws xob txawv raws li qhov kub thiab txias, av noo, cua ceev thiab lwm yam ntawm qhov chaw uas nws siv. Thaum qhov kub thiab txias tsawg, lub peev xwm tso tawm kuj qis. Thaum av noo nce, nws cov nyhuv sterilization kuj yuav txo qis. Cov teeb UV feem ntau yog tsim los ntawm qhov av noo ze li ntawm 60%. Thaum cov av noo sab hauv tsev nce, qhov ntau ntawm irradiation kuj yuav tsum nce raws li vim tias qhov cuam tshuam sterilization txo qis. Piv txwv li, thaum cov av noo yog 70%, 80%, thiab 90%, txhawm rau kom ua tiav tib qho txiaj ntsig sterilization, qhov ntau ntawm cov hluav taws xob yuav tsum tau nce 50%, 80%, thiab 90% feem. Cua ceev kuj cuam tshuam rau lub peev xwm tso tawm. Tsis tas li ntawd, txij li thaum cov nyhuv bactericidal ntawm lub teeb ultraviolet sib txawv nrog ntau hom kab mob, qhov ntau ntawm ultraviolet irradiation yuav tsum sib txawv rau ntau hom kab mob. Piv txwv li, qhov ntau ntawm irradiation siv los tua cov fungi yog 40 txog 50 npaug ntau dua li qhov siv los tua cov kab mob. Yog li ntawd, thaum xav txog qhov cuam tshuam sterilization ntawm cov teeb ultraviolet germicidal, qhov cuam tshuam ntawm qhov siab teeb tsa tsis tuaj yeem tsis quav ntsej. Lub zog tua kab mob ntawm cov teeb ultraviolet yuav ploj mus raws sijhawm. Lub zog tso zis ntawm 100b yog suav tias yog lub zog ntsuas, thiab lub sijhawm siv ntawm lub teeb ultraviolet mus rau 70% ntawm lub zog ntsuas yog suav tias yog lub neej nruab nrab. Thaum lub sijhawm siv ntawm lub teeb ultraviolet tshaj lub neej nruab nrab, qhov cuam tshuam xav tau yuav tsis tuaj yeem ua tiav thiab yuav tsum tau hloov pauv lub sijhawm no. Feem ntau, lub neej nruab nrab ntawm cov teeb ultraviolet hauv tsev yog 2000h. Qhov cuam tshuam tua kab mob ntawm cov teeb ultraviolet yog txiav txim siab los ntawm nws cov hluav taws xob ntau npaum li cas (qhov hluav taws xob ntau npaum li cas ntawm cov teeb ultraviolet germicidal kuj tseem tuaj yeem hu ua qhov kab tua kab mob), thiab qhov hluav taws xob ib txwm sib npaug rau qhov muaj zog ntawm cov hluav taws xob ntau npaum li cas los ntawm lub sijhawm hluav taws xob, yog li nws yuav tsum tau nce cov nyhuv hluav taws xob, nws yog qhov tsim nyog los nce qhov muaj zog ntawm cov hluav taws xob lossis ntev lub sijhawm hluav taws xob.
