Hauv kev lag luam xws li kev lag luam tshuaj, kev lag luam zaub mov, khoom siv roj ntsha, kev kho mob thiab kev noj qab haus huv, thiab kev tshawb fawb tshawb fawb, tshuaj tua kab mob thiab tshuaj tua kab mob feem ntau yog siv los tua kab mob thiab ua kom tsis muaj menyuam muaj feem cuam tshuam.
Ntawm tag nrho cov kev siv tshuaj tua kab mob thiab kev ua kom tsis muaj menyuam, chav dej yog qhov ntxov tshaj plaws, txhim khu kev qha thiab feem ntau siv txoj kev.Nws tuaj yeem tua tag nrho cov kab mob, suav nrog cov kab mob propagules, fungi, protozoa, algae, kab mob thiab tiv thaiv.Cov kab mob spores muaj zog dua, yog li chav ua kom tsis muaj menyuam muaj nuj nqis heev hauv kev tua kab mob thiab ua kom tsis muaj menyuam.Thaum ntxov suav tshuaj sterilization yuav luag ib txwm siv chav sterilization.
Steam sterilization siv lub zog siab los yog lwm yam khoom siv cua sov kom tsis muaj menyuam los tua cov kab mob hauv lub sterilizer.Nws yog txoj kev zoo tshaj plaws thiab siv dav hauv thermal sterilization.
Rau cov khoom noj, cov ntaub ntawv uas tau rhuab thaum lub sij hawm kom tsis muaj menyuam yuav tsum tswj cov khoom noj khoom haus thiab tsw ntawm cov khoom noj.Kev siv lub zog ntawm ib qho khoom noj khoom haus thiab dej haus kuj yog ib qho tseem ceeb thaum xav txog kev sib tw ntawm kev lag luam.Rau cov tshuaj, thaum ua tiav cov tshuaj tua kab mob thiab ua kom tsis muaj menyuam, lawv yuav tsum tau xyuas kom meej tias cov tshuaj tsis raug puas tsuaj thiab ua kom muaj kev nyab xeeb, kev ua tau zoo thiab ruaj khov ntawm lawv cov kev ua tau zoo.
Cov tshuaj, cov tshuaj kho mob, iav, kab lis kev cai xov xwm, hnav khaub ncaws, ntaub, cov cuab yeej hlau thiab lwm yam khoom uas yuav tsis hloov lossis puas thaum raug kub thiab noo cua sov tuaj yeem ua kom tsis muaj qhov cub.Qhov dav siv siab ua kom tsis muaj menyuam thiab sterilization txee yog cov khoom siv classic rau chav ua kom tsis muaj menyuam thiab ua kom tsis muaj menyuam.Txawm hais tias muaj ntau yam tshiab ntawm cov khoom siv cua sov kom tsis muaj menyuam tau tsim nyob rau xyoo tas los no kom tau raws li ntau yam kev xav tau, lawv txhua tus ua raws li lub siab ua kom tsis muaj menyuam thiab ua kom tsis muaj menyuam.tsim los ntawm.
Chav feem ntau ua rau cov kab mob tuag los ntawm coagulating lawv cov proteins.Chav muaj zog penetrability.Yog li ntawd, thaum chav condenses, nws tso tawm ib tug loj npaum li cas ntawm latent tshav kub, uas yuav sai sai cua sov khoom.Steam sterilization tsis yog tsuas yog txhim khu kev qha, tab sis kuj tuaj yeem txo qhov ntsuas kub kom tsis muaj menyuam thiab ua kom lub sijhawm luv.Lub sijhawm ua haujlwm.Qhov sib xws, nkag mus, kev ntseeg tau, kev ua haujlwm thiab lwm yam ntawm kev ua kom tsis muaj menyuam tau dhau los ua qhov tseem ceeb rau kev ua kom tsis muaj menyuam.
Cov chav ntawm no yog hais txog qhov qhuav saturated chav.Es tsis txhob superheated chav siv nyob rau hauv kev lag luam uas tsim ntau yam roj thiab petrochemical khoom thiab nyob rau hauv lub hwj chim chaw nres tsheb chav turbines, superheated chav tsis haum rau sterilization txheej txheem.Txawm hais tias superheated chav muaj qhov kub thiab txias dua thiab muaj cua sov ntau dua li cov chav dej saturated, nws cov cua sov ntawm qhov superheated yog me me heev piv nrog cov cua sov latent ntawm vaporization tso tawm los ntawm condensation ntawm saturated chav.Thiab nws yuav siv sij hawm ntev los tso lub superheated chav kub mus rau qhov kub thiab txias.Kev siv superheated chav rau cua sov yuav txo qhov kev sib pauv cua sov.
Ntawm chav kawm, moist chav uas muaj cov dej condensed yog qhov phem dua.Ntawm qhov tod tes, cov dej noo uas muaj nyob hauv cov dej noo nws tus kheej yuav yaj qee qhov impurities hauv cov kav dej.Ntawm qhov tod tes, thaum cov dej noo mus txog cov hlab ntsha thiab cov tshuaj kom tsis muaj menyuam, nws cuam tshuam cov dej ntws mus rau lub hnub qub kws tshuaj.Hla, txo qhov kub ntawm qhov hla.Thaum lub qhov cub muaj cov huab cua zoo dua, nws tsim ib qho kev thaiv rau cov roj ntws thiab tiv thaiv kom tsis txhob muaj cua sov los ntawm kev nkag mus, thiab nws kuj ua rau qhov nyuaj ntawm ziab tom qab kom tsis muaj menyuam.
Qhov sib txawv ntawm qhov ntsuas kub ntawm txhua qhov taw tes hauv qhov txwv kom tsis muaj menyuam ntawm lub txee kom tsis muaj menyuam thiab nws qhov nruab nrab kub yog ≤1 ° C.Nws tseem yuav tsum tau tshem tawm "cov chaw txias" thiab qhov sib txawv ntawm "cov chaw txias" thiab qhov nruab nrab kub (≤2.5 ° C) kom ntau li ntau tau.Yuav ua li cas kom tshem tawm cov roj uas tsis yog-condensable hauv chav, ua kom qhov sib xws ntawm qhov kub thiab txias hauv chav ua kom tsis muaj menyuam, thiab tshem tawm "qhov chaw txias" kom ntau li ntau tau yog cov ntsiab lus tseem ceeb hauv kev tsim cov chav ua kom tsis muaj menyuam.
Lub sterilization kub ntawm saturated chav yuav tsum sib txawv raws li lub tshav kub kam rau cov kab mob.Yog li ntawd, qhov yuav tsum tau ua kom tsis muaj menyuam kub thiab lub sijhawm ua haujlwm kuj txawv raws li qib kev sib kis ntawm cov khoom tsis huv, thiab qhov ntsuas kub thiab lub sijhawm ua haujlwm kuj txawv.Qhov kev xaiv nyob ntawm txoj kev ua kom tsis muaj menyuam, kev ua haujlwm ntawm cov khoom, cov khoom ntim, thiab qhov yuav tsum tau ua kom tsis muaj menyuam ntev.Feem ntau hais lus, qhov siab dua qhov ntsuas kub kom tsis muaj menyuam, lub sijhawm luv dua.Muaj kev sib raug zoo tsis tu ncua ntawm qhov kub thiab txias ntawm chav saturated thiab nws lub siab.Txawm li cas los xij, thaum huab cua hauv lub txee tsis raug tshem tawm lossis tsis raug tshem tawm tag nrho, cov chav tsis tuaj yeem ncav cuag saturation.Lub sijhawm no, txawm hais tias qhov siab The 'meter' qhia tau hais tias qhov kev ua kom tsis muaj menyuam tau mus txog, tab sis qhov ntsuas kub tsis tau mus txog qhov yuav tsum tau ua, ua rau kom tsis muaj menyuam tsis ua haujlwm.Txij li thaum lub qhov cub qhov siab yog feem ntau siab dua qhov kev ua kom tsis muaj menyuam, thiab chav decompression tuaj yeem ua rau cov cua kub dhau, kev saib xyuas yuav tsum tau them.
