Ethylene Oxide & Carbon Dioxide Mixtures

Technical parameters

Ethylene oxide yog ib qho yooj yim cyclic ethers. Nws yog heterocyclic compound. Nws cov tshuaj formula yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab ib qho tseem ceeb petrochemical khoom. Cov khoom siv tshuaj lom neeg ntawm ethylene oxide muaj zog heev. Nws tuaj yeem raug lub nplhaib-qhib ntxiv cov tshuaj tiv thaiv nrog ntau lub tebchaw thiab tuaj yeem txo cov nyiaj nitrate. Nws yog ib qho yooj yim rau polymerize tom qab rhuab thiab decompose nyob rau hauv lub xub ntiag ntawm hlau ntsev los yog oxygen. Ethylene oxide yog cov kua tsis muaj xim thiab pob tshab ntawm qhov kub thiab txias, thiab cov roj tsis muaj xim nrog ether pungent tsw ntawm qhov kub thiab txias. Lub vapor siab ntawm cov pa roj yog siab, ncav cuag 141kPa ntawm 30 ° C. Qhov siab vapor siab no txiav txim siab txog epoxy Strong penetrating zog thaum ethane fumigation thiab tshuaj tua kab mob. Ethylene oxide muaj cov kab mob bactericidal, tsis corrosive rau hlau, tsis muaj ntxhiab tsw seem, thiab tuaj yeem tua cov kab mob (thiab nws cov endospores), pwm thiab fungi, yog li nws tuaj yeem siv los tua kab mob qee yam khoom thiab cov ntaub ntawv uas tsis tuaj yeem tiv taus cov tshuaj tua kab mob siab. . . Ethylene oxide yog cov tshuaj tua kab mob thib ob tom qab formaldehyde. Nws tseem yog ib qho ntawm cov tshuaj tua kab mob zoo tshaj plaws. Nws tseem yog plaub qhov tseem ceeb ntawm kev ua kom tsis muaj qhov kub thiab txias technologies (low-temperature plasma, low-temperature formaldehyde steam, ethylene oxide). , Glutaraldehyde) cov tswv cuab tseem ceeb tshaj plaws. Feem ntau siv ethylene oxide-carbon dioxide (qhov piv ntawm ob yog 90:10) lossis ethylene oxide-dichlorodifluoromethane sib tov, feem ntau yog siv rau kev tua kab mob hauv tsev kho mob thiab cov cuab yeej precision. Ethylene oxide yog nplaim taws thiab tawg, thiab nws cov khoom siv tshuaj muaj zog heev. Nws tuaj yeem raug lub nplhaib-qhib ntxiv cov tshuaj tiv thaiv nrog ntau lub tebchaw. Nws tsis yooj yim rau kev thauj mus los ntev, yog li nws muaj zog hauv cheeb tsam cov yam ntxwv. Kev ceev faj cia: Khaws rau hauv qhov chaw txias, qhov cua txias. Khaws kom deb ntawm qhov hluav taws kub thiab cua sov. Zam lub teeb. Qhov kub cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum tau muab cais tawm ntawm cov kua qaub, alkalis, cawv, thiab cov tshuaj noj tau, thiab tsis txhob sib xyaw cia. Siv cov khoom tawg-pov thawj teeb pom kev zoo thiab qhov cua qhov cua. Nws yog txwv tsis pub siv cov cuab yeej siv kho tshuab thiab cov cuab yeej uas nquag ua rau lub txim taws. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Daim ntawv thov:

① Sterilization:

Ethylene oxide muaj cov kab mob bactericidal, tsis corrosive rau hlau, tsis muaj ntxhiab tsw seem, thiab tuaj yeem tua cov kab mob (thiab nws cov endospores), pwm thiab fungi, yog li nws tuaj yeem siv los tua kab mob qee yam khoom thiab cov ntaub ntawv uas tsis tuaj yeem tiv taus cov tshuaj tua kab mob siab. .
