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

EOyog ib tug dav-spectrum sterilant uas tua tau ntau yam kab mob nyob rau hauv chav tsev kub, nrog rau spores, tuberculosis kab mob, kab mob, kab mob, fungi, thiab lwm yam nyob rau hauv chav tsev kub thiab siab,EOyog cov roj tsis muaj xim, hnyav dua li huab cua, thiab muaj ntxhiab tsw ntxhiab ether. Thaum qhov kub thiab txias qis dua 10.8 ℃, cov roj liquefies thiab dhau los ua cov kua tsis muaj xim pob tshab ntawm qhov kub qis. Nws tuaj yeem tov nrog dej hauv txhua qhov kev faib ua feem thiab tuaj yeem yaj hauv cov kuab tshuaj organic uas nquag siv. Lub vapor siab ntawm EO yog qhov loj, yog li nws muaj zog nkag mus rau hauv cov khoom tsis huv, tuaj yeem nkag mus rau micropores thiab ncav cuag qhov tob ntawm cov khoom, uas yog qhov zoo rau kev ua kom tsis muaj menyuam.

Sterilization kub

Hauvethylene oxidesterilizer, lub zog ntawm ethylene oxide molecules intensifies raws li qhov kub thiab txias, uas yog conducive rau nws mus txog qhov sib thooj thiab txhim kho cov nyhuv sterilization. Txawm li cas los xij, hauv cov txheej txheem tsim khoom tiag tiag, qhov ntsuas kub kom tsis muaj menyuam tsis tuaj yeem nce ntxiv mus ib txhis. Ntxiv nrog rau kev xav txog cov nqi hluav taws xob, kev ua haujlwm ntawm cov khoom siv, thiab lwm yam, qhov cuam tshuam ntawm qhov kub thiab txias ntawm cov khoom lag luam yuav tsum tau txiav txim siab. Kev kub siab heev tuaj yeem ua rau kom cov khoom puas ntawm cov ntaub ntawv polymer, ua rau cov khoom tsis tsim nyog lossis ua haujlwm luv luv, thiab lwm yam.Yog li ntawd, ethylene oxide sterilization kub feem ntau yog 30-60 ℃.

txheeb ze humidity

Dej yog ib tus neeg koom nrogethylene oxidekev ua kom tsis muaj menyuam. Tsuas yog los ntawm kev ua kom cov av noo nyob rau hauv lub sterilizer tuaj yeem ua rau cov ethylene oxide thiab cov kab mob me me tau txais cov tshuaj tiv thaiv alkylation kom ua tiav lub hom phiaj ntawm kev ua kom tsis muaj menyuam. Nyob rau tib lub sijhawm, cov dej muaj peev xwm kuj tuaj yeem ua kom qhov kub thiab txias ntawm cov tshuaj tua kab mob thiab txhawb kev sib faib ntawm cov hluav taws xob hluav taws xob.Tus txheeb ze humidity ntawmethylene oxidesterilization yog 40% -80%.Thaum nws qis dua 30%, nws yooj yim ua rau kom tsis muaj menyuam.

Nco ntsoov

Tom qab txiav txim siab qhov kub thiab txias thiab txheeb ze humidity, lubethylene oxideconcentration thiab sterilization efficiency feem ntau qhia ib tug thawj-order kinetic cov tshuaj tiv thaiv, uas yog, cov tshuaj tiv thaiv tus nqi nce nrog rau qhov nce ntawm ethylene oxide concentration nyob rau hauv lub sterilizer. Txawm li cas los xij, nws txoj kev loj hlob tsis txwv.Thaum qhov kub siab tshaj 37 ° C thiab cov ethylene oxide concentration ntau dua 884 mg / L, nws nkag mus rau hauv lub xeev xoom-kev txiav txim., thiab covethylene oxideconcentration muaj me ntsis cuam tshuam rau cov tshuaj tiv thaiv tus nqi.

Lub Sijhawm Ua Haujlwm

Thaum ua kom tsis muaj menyuam validation, ib nrab-lub voj voog txoj kev feem ntau yog siv los txiav txim lub sij hawm kom tsis muaj menyuam. Txoj kev ib nrab-lub voj voog txhais tau hais tias thaum lwm qhov tsis muaj tshwj tsis yog lub sijhawm tsis hloov pauv, lub sijhawm ua haujlwm yog halved nyob rau hauv ib nrab mus txog rau lub sijhawm luv tshaj plaws rau cov khoom tsis muaj menyuam kom ncav cuag lub xeev tsis muaj menyuam. Kev kuaj kom tsis muaj menyuam yog rov ua dua 3 zaug. Yog tias qhov ua kom tsis muaj menyuam tuaj yeem ua tiav, nws tuaj yeem txiav txim siab ua ib nrab-lub voj voog. Txhawm rau kom ua kom tsis muaj menyuam,lub sij hawm ua kom tsis muaj menyuam tiag tiag yuav tsum yog tsawg kawg ob zaug ntawm ib nrab-lub voj voog, tab sis lub sijhawm ua haujlwm yuav tsum suav txij thaum qhov kub thiab txias, txheeb ze av noo,ethylene oxideconcentration thiab lwm yam kev mob nyob rau hauv lub sterilizer raws li sterilization yuav tsum tau.

Cov ntaub ntawv ntim khoom

Txoj kev ua kom tsis muaj menyuam sib txawv muaj qhov sib txawv rau cov khoom ntim khoom. Kev hloov pauv ntawm cov khoom ntim khoom siv rau kev ua kom tsis muaj menyuam yuav tsum raug txiav txim siab. Cov khoom ntim zoo, tshwj xeeb tshaj yog cov khoom ntim tsawg tshaj plaws, muaj feem cuam tshuam ncaj qha rau kev ua kom tsis muaj menyuam ntawm ethylene oxide. Thaum xaiv cov khoom ntim, yam tsawg kawg nkaus xws li kev ua kom tsis muaj menyuam, huab cua permeability, thiab cov khoom siv tshuaj tua kab mob yuav tsum raug txiav txim siab.Ethylene oxideKev ua kom tsis muaj menyuam yuav tsum tau ntim cov ntaub ntawv kom muaj qee qhov huab cua permeability.
