Cov qauv tshiab zoo dua li yav dhau los thiab lawv nrov heev nrog ntau tus neeg siv khoom.

Cov kev tsis sib xws

Ethylene oxide yog ib qho ntawm cov cyclic ethers yooj yim tshaj plaws. Nws yog ib qho heterocyclic compound. Nws cov mis tshuaj yog C2H4O. Nws yog ib qho tshuaj lom carcinogen thiab yog ib yam khoom tseem ceeb petrochemical. Cov khoom siv tshuaj ntawm ethylene oxide yog cov khoom siv heev. Nws tuaj yeem dhau los ntawm kev sib xyaw ua ke nrog ntau cov tshuaj thiab tuaj yeem txo cov nyiaj nitrate. Nws yooj yim rau polymerize tom qab raug cua sov thiab tuaj yeem decompose nyob rau hauv qhov muaj cov ntsev hlau lossis oxygen. Ethylene oxide yog cov kua tsis muaj xim thiab pob tshab ntawm qhov kub qis, thiab yog cov roj tsis muaj xim nrog ether pungent tsw ntawm qhov kub ib txwm. Lub zog vapor ntawm cov roj yog siab, ncav cuag 141kPa ntawm 30 ° C. Lub zog vapor siab no txiav txim siab epoxy Lub zog nkag mus rau hauv lub zog thaum lub sijhawm ethane fumigation thiab disinfection. Ethylene oxide muaj cov nyhuv bactericidal, tsis corrosive rau cov 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 cov khoom thiab cov ntaub ntawv uas tsis tuaj yeem tiv taus qhov kub siab disinfection. . Ethylene oxide yog tiam thib ob tshuaj tua kab mob tom qab formaldehyde. Nws tseem yog ib qho ntawm cov tshuaj tua kab mob txias zoo tshaj plaws. Nws tseem yog plaub lub tshuab ua kom tsis muaj kab mob kub tsawg (plasma kub tsawg, formaldehyde pa kub tsawg, ethylene oxide). , Glutaraldehyde) yog tus tswv cuab tseem ceeb tshaj plaws. Feem ntau siv ethylene oxide-carbon dioxide (qhov sib piv ntawm ob yog 90:10) lossis ethylene oxide-dichlorodifluoromethane sib xyaw, feem ntau yog siv rau kev tua kab mob ntawm cov tsev kho mob thiab cov cuab yeej siv precision. Ethylene oxide yog flammable thiab tawg, thiab nws cov khoom siv tshuaj lom neeg muaj zog heev. Nws tuaj yeem dhau los ntawm kev sib xyaw ua ke nrog ntau cov tshuaj sib xyaw. Nws tsis yooj yim rau kev thauj mus los ntev, yog li nws muaj cov yam ntxwv hauv cheeb tsam muaj zog. Kev ceev faj txog kev khaws cia: Khaws cia rau hauv lub tsev cia khoom txias, muaj cua nkag. Khaws cia kom deb ntawm hluav taws thiab cua sov. Tsis txhob muaj teeb. Qhov kub khaws cia yuav tsum tsis pub tshaj 30 ° C. Nws yuav tsum khaws cia cais ntawm cov kua qaub, alkalis, cawv, thiab cov tshuaj noj tau, thiab tsis txhob khaws cia sib xyaw. Siv cov teeb pom kev zoo thiab cov chaw ua pa uas tsis tawg. Txwv tsis pub siv cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim rau hluav taws xob. Thaj chaw khaws cia yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm txheej ceev.

Daim Ntawv Thov:

① Kev Ua Kom Tsis Muaj Mob:

Ethylene oxide muaj cov nyhuv tua kab mob, tsis yog corrosive rau cov 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 kev tua kab mob kub siab.
