Cov ntaub ntawv ntawm cov khoom siv kho mob tuaj yeem muab faib ua ob pawg: cov ntaub ntawv hlau thiab cov ntaub ntawv polymer. Cov khoom ntawm cov ntaub ntawv hlau yog qhov ruaj khov thiab muaj kev kam rau ntau txoj kev tua kab mob. Yog li ntawd, kev kam rau ntawm cov ntaub ntawv polymer feem ntau raug txiav txim siab hauv kev xaiv cov txheej txheem tua kab mob. Cov ntaub ntawv polymer kho mob feem ntau siv rau cov khoom siv kho mob yog polyethylene, polyvinyl chloride, polypropylene, polyester, thiab lwm yam, txhua yam muaj kev hloov pauv zoo rau cov khoom siv.Ethylene oxide (EO)txoj kev ua kom tsis muaj menyuam.

EOyog ib qho tshuaj tua kab mob dav dav uas tuaj yeem tua ntau yam kab mob me me ntawm chav tsev kub, suav nrog cov noob kab mob, cov kab mob ntsws, cov kab mob, cov kab mob fungi, thiab lwm yam. Thaum chav tsev kub thiab siab,EOyog ib qho roj tsis muaj xim, hnyav dua li huab cua, thiab muaj ntxhiab tsw ntawm ether. Thaum qhov kub qis dua 10.8 ℃, cov roj yuav ua kua thiab ua kua tsis muaj xim pob tshab ntawm qhov kub qis. Nws tuaj yeem sib xyaw nrog dej hauv txhua qhov sib piv thiab tuaj yeem yaj rau hauv cov kuab tshuaj organic uas siv ntau. Lub zog vapor ntawm EO yog qhov loj heev, yog li nws muaj kev nkag mus rau hauv cov khoom sterilized, tuaj yeem nkag mus rau hauv cov micropores thiab ncav cuag qhov tob ntawm cov khoom, uas yog qhov zoo rau kev ua kom huv si.

Kub ntawm kev ua kom tsis muaj menyuam

Nyob rau hauv lubethylene oxidelub tshuab ua kom tsis muaj kab mob, qhov kev txav ntawm cov ethylene oxide molecules nce ntxiv thaum qhov kub nce, uas yog qhov zoo rau nws mus txog cov khoom sib xws thiab txhim kho cov nyhuv ua kom tsis muaj kab mob. Txawm li cas los xij, hauv cov txheej txheem tsim khoom tiag tiag, qhov kub ntawm kev ua kom tsis muaj kab mob tsis tuaj yeem nce ntxiv mus tas li. Ntxiv nrog rau kev xav txog cov nqi zog, kev ua haujlwm ntawm cov khoom siv, thiab lwm yam, qhov cuam tshuam ntawm qhov kub rau kev ua haujlwm ntawm cov khoom kuj yuav tsum tau xav txog. Qhov kub siab dhau heev tuaj yeem ua rau cov khoom polymer lwj sai dua, ua rau cov khoom tsis tsim nyog lossis lub neej ua haujlwm luv dua, thiab lwm yam.Yog li ntawd, qhov kub ntawm ethylene oxide sterilization feem ntau yog 30-60 ℃.

Qhov av noo sib piv

Cov dej yog ib feem ntawm kev sib ntaus sib tuaethylene oxidekev ua kom tsis muaj kab mob. Tsuas yog los ntawm kev ua kom muaj qee qhov av noo hauv lub tshuab ua kom tsis muaj kab mob xwb, cov ethylene oxide thiab cov kab mob me me thiaj li ua rau muaj kev ua kom tsis muaj kab mob los ua kom tiav lub hom phiaj ntawm kev ua kom tsis muaj kab mob. Tib lub sijhawm, qhov muaj dej kuj tseem tuaj yeem ua rau qhov kub nce ntxiv hauv lub tshuab ua kom tsis muaj kab mob thiab txhawb kev faib tawm ntawm lub zog cua sov.Qhov av noo ntawmethylene oxidekev ua kom tsis muaj menyuam yog 40% -80%.Thaum nws qis dua 30%, nws yooj yim ua rau tsis ua haujlwm kom tsis muaj menyuam.

Kev Ntsuas

Tom qab txiav txim siab qhov kub thiab txias ntawm kev ua kom huv thiab qhov av noo,ethylene oxideFeem ntau, qhov concentration thiab sterilization efficiency qhia txog thawj qhov kev ua haujlwm kinetic, uas yog, qhov kev ua haujlwm nce ntxiv nrog rau qhov nce ntawm ethylene oxide concentration hauv lub sterilizer. Txawm li cas los xij, nws txoj kev loj hlob tsis yog qhov txwv.Thaum qhov kub tshaj 37 ° C thiab qhov concentration ntawm ethylene oxide ntau dua 884 mg / L, nws nkag mus rau hauv lub xeev xoom-order reaction., thiab covethylene oxideqhov concentration tsis muaj feem cuam tshuam rau qhov nrawm ntawm cov tshuaj tiv thaiv.

Lub Sijhawm Ua Haujlwm

Thaum ua qhov kev lees paub txog kev tua kab mob, txoj kev ib nrab voj voog feem ntau yog siv los txiav txim siab lub sijhawm tua kab mob. Txoj kev ib nrab voj voog txhais tau tias thaum lwm yam kev ntsuas tshwj tsis yog lub sijhawm tseem tsis tau hloov pauv, lub sijhawm ua haujlwm raug txiav ib nrab ua ntu zus kom txog thaum lub sijhawm luv tshaj plaws rau cov khoom tua kab mob kom mus txog qhov xwm txheej tua kab mob. Kev sim tua kab mob rov ua dua 3 zaug. Yog tias qhov txiaj ntsig tua kab mob tuaj yeem ua tiav, nws tuaj yeem txiav txim siab ua ib nrab voj voog. Txhawm rau kom ntseeg tau tias qhov txiaj ntsig tua kab mob,lub sijhawm ua kom huv tiag tiag yuav tsum yog tsawg kawg yog ob npaug ntawm ib nrab ntawm lub voj voog, tab sis lub sijhawm ua haujlwm yuav tsum suav txij thaum qhov kub thiab txias, qhov av noo,ethylene oxidekev sib xyaw thiab lwm yam mob hauv lub tshuab ua kom tsis muaj menyuam ua tau raws li qhov yuav tsum tau ua kom tsis muaj menyuam.

Cov ntaub ntawv ntim khoom

Cov txheej txheem sterilization sib txawv muaj cov kev cai sib txawv rau cov ntaub ntawv ntim khoom. Yuav tsum xav txog qhov kev hloov pauv ntawm cov ntaub ntawv ntim khoom siv rau cov txheej txheem sterilization. Cov ntaub ntawv ntim khoom zoo, tshwj xeeb tshaj yog cov ntaub ntawv ntim khoom me tshaj plaws, muaj feem cuam tshuam ncaj qha rau cov nyhuv sterilization ntawm ethylene oxide. Thaum xaiv cov ntaub ntawv ntim khoom, tsawg kawg yog cov yam xws li kev kam rau siab sterilization, huab cua permeability, thiab cov khoom antibacterial yuav tsum tau xav txog.Ethylene oxideKev ua kom tsis muaj menyuam yuav tsum tau cov ntaub ntawv ntim khoom kom muaj qee qhov cua nkag tau.
