Ethylene oxide (EO) tau siv tshuaj tua kab mob thiab kom tsis muaj menyuam ntev thiab yog cov tshuaj lom neeg muaj peev xwm lees paub los ntawm lub ntiaj teb uas yog cov ntseeg tau tshaj plaws. Yav dhau los,Ethylene oxideFeem ntau yog siv rau kev siv tshuaj ntsuam-teev thiab kom tsis muaj menyuam. Nrog rau kev txhim kho kev lag luam niaj hnub thiab kev siv tshuab thiab cov thev naus laus zis thiab cov tshuab hluav taws xob muaj kev nyab xeeb tuaj yeem nyab xeeb rau cov khoom siv kho mob uas tsis txaus siab thiab noo noo.

Cov yam ntxwv ntawm Ethylene Oxide

Ethylene oxideyog lub cim thib ob ntawm tshuaj tua kab mob tom qab formaldehyde. Nws yog tseem yog ib qho ntawm cov kab mob txias zoo tshaj plaws thiab cov tswv cuab tseem ceeb tshaj plaws ntawm plaub qhov loj tsawg tsawg-kub kom tsis muaj menyuam yaus thev naus laus zis.

Ethylene oxide yog ib qho yooj yim epoxy compound. Nws yog cov pa roj tsis muaj kob ntawm chav sov thiab siab. Nws yog hnyav dua cua thiab muaj cov ntxhiab tsw ntxhiab ether. Ethylene oxide yog nplaim taws thiab tawg. Thaum cov huab cua muaj 3% rau 80%Ethylene oxide, cov roj sib xyaw tawg tau yog tsim, uas hlawv lossis tawg thaum raug rau cov nplaim taws. Cov feem ntau siv ethylene oxide ethlene oxide etherraction rau kev tua kab mob thiab kom tsis muaj menyuam yog nyob rau hauv cov huab cua, yog li nws yuav tsum tau siv nrog kev ceev faj.

Ethylene oxide tuaj yeem sib xyaw nrog cov roj hauv cov roj xws licarbon dioxideHauv qhov sib piv ntawm 1: 9 los ua kev tawg-ntawv pov thawj sib tov, uas muaj kev nyab xeeb rau kev kho mob thiab kom tsis muaj menyuam.Ethylene oxidePuas yog polymerize, tab sis feem ntau cov polymerization yog qeeb thiab feem ntau tshwm sim hauv lub xeev ua kua. Hauv kev sib xyaw ntawm ethylene oxide nrog carbon dioxide lossis fluorinated hydrocarbons, polymerization tshwm sim qeeb dua thiab tawv polymers tsis tshua tawg.

Lub hauv paus ntsiab lus ntawm ethylene oxide sterilization

1. Alkylation

Lub tshuab ntawm kev ua ntawmEthylene oxideHauv kev tua cov microorganism feem ntau yog alkylation. Cov chaw ntawm kev nqis tes yog sulfhydryl (-sh), amino (-cooth) thiab hydroxyl (-h) hauv cov protein thiab nucleic acid molecules. Ethylene oxide tuaj yeem ua rau cov pab pawg no txhawm rau txhawm rau ua alkylation cov tshuaj tiv thaiv, ua cov roj ntsha macromolecules ntawm cov kab mob tsis sib xws, yog li tua cov kab mob sib kis.

2. Inhibit cov kev ua si ntawm cov roj ntsha enzizes

Ethylene oxide tuaj yeem inhibit qhov kev ua ub no ntawm ntau cov enzymes ntawm cov kab mob methdrogenase ,, (choline oxoesterase, tabkaum ua tiav ntawm cov txheej txheem methabolic ntawm cov kab mob methabolic thiab ua rau lawv tuag.

3. Tua cov nyhuv ntawm cov microorganisms

Ob yamEthylene oxideKua thiab roj muaj cov teebmeem microbicid muaj zog. Hauv kev sib piv, cov nyhuv microbicidid ntawm cov roj muaj zog dua, thiab nws cov roj av feem ntau siv hauv kev ua haujlwm tsis huv thiab kom tsis muaj menyuam.

Ethylene oxide yog qhov ua tau zoo heev rau sterilant uas muaj kev tua cov kab mob uas muaj zog tua cov kab mob, cov kab mob kab mob, fungi, thiab cov kab mob. Thaum Ethylene oxide los rau hauv kev sib chwv nrog cov kab mob me, tab sis cov kab mob muaj cov tshuaj tiv thaiv oxylene thiab cov kab mob sib txawv yog cov tshuaj tiv thaiv thawj zaug. Qhov koob tshuaj uas tsis muaj kev tiv thaiv cov kab mob muaj cov kab mob, cov tshuaj tiv thaiv kab mob yog ib txoj kab ncaj qha rau cov nqi ncaj ncees.

Kev thov cov kev thov ethylene oxide kom tsis muaj menyuam

Ethylene oxideTsis muaj kev puas tsuaj rau cov khoom tsis huv thiab muaj cov nkag siab muaj zog. Cov khoom feem ntau uas tsis haum rau kom tsis muaj menyuam los ntawm cov hau kev dav dav tuaj yeem raug tshuaj tua kab mob nrog ethylene oxide. Nws tuaj yeem siv rau qhov tsis muaj menyuam ntawm cov khoom lag luam hlau, cov khoom siv roj av, xws li cov khoom siv roj ntsha, cov khoom siv yas, tawv, thiab cov ntaub ntawv, thiab cov duab pleev duab).

Ethylene oxide tsis muaj kev puas tsuaj rau cov khoom tsis huv thiab muaj kev nkag siab zoo. Cov khoom feem ntau uas tsis haum rau kom tsis muaj menyuam los ntawm cov hau kev dav dav tuaj yeem raug tshuaj tua kab mob nrog ethylene oxide. Nws tuaj yeem siv rau qhov tsis muaj menyuam ntawm cov khoom lag luam hlau, cov khoom siv roj av, xws li cov khoom siv roj ntsha, cov khoom siv yas, tawv, thiab cov ntaub ntawv, thiab cov duab pleev duab).

Yam cuam tshuam rau kev tsis muaj menyuam nyhuv ntawmEthylene oxide

Lub kom tsis muaj menyuam nyhuv ntawm ethylene oxide cuam tshuam los ntawm ntau yam. Txhawm rau kom ua tiav cov txiaj ntsig zoo tshaj plaws, tsuas yog los ntawm kev tswj hwm tau zoo ntxiv rau ntau yam nws tuaj yeem ua tau zoo tshaj plaws hauv kev tua cov kab mob me thiab ua tiav nws lub hom phiaj ntawm kev rho tawm thiab kom tsis muaj menyuam. Cov ntsiab lus tseem ceeb cuam tshuam rau cov nyhuv tsis muaj menyuam yog: morrine, ntsuas kub, kwv yees lub sijhawm, thiab lwm yam.
