2019 Tuam Tshoj Tshiab Tsim Tuam Tshoj Eto

Peb lub hom phiaj yog nrhiav kom paub txog qhov zoo ntawm kev tsim khoom thiab muab cov kev pabcuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws rau 2019 Tuam Tshoj Tsim Tshiab Tuam Tshoj Eto, Peb lub tuam txhab txais tos cov phooj ywg los ntawm txhua qhov chaw hauv ib puag ncig mus rau, tshuaj xyuas thiab sib tham txog lub koom haum.
Peb lub hom phiaj yog nrhiav kom paub txog qhov zoo ntawm kev puas tsuaj los ntawm kev tsim khoom thiab muab cov kev pabcuam zoo tshaj plaws rau cov neeg siv khoom hauv tsev thiab txawv teb chaws tag nrho lub siab rauEthylene Oxide nrog CO2 Gas SterilizationTxawm hais tias muaj lub cib fim tas mus li, tam sim no peb tau tsim kev sib raug zoo nrog ntau tus tub luam txawv teb chaws, xws li cov neeg los ntawm Virginia. Peb ntseeg siab tias cov khoom lag luam ntawm lub tshuab luam ntawv t-shirt feem ntau zoo vim muaj ntau tus neeg muaj nws qhov zoo thiab tus nqi.

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 menyuam kub tsawg (plasma kub tsawg, formaldehyde pa kub tsawg, ethylene oxide). , Glutaraldehyde) yog tus tswv cuab tseem ceeb tshaj plaws. Ethylene oxide kuj tseem siv los ua ntau yam tshuaj yaj (xws li cellosolve, thiab lwm yam), diluents, non-ionic surfactants, synthetic detergents, antifreeze, disinfectants, tougheners thiab plasticizers, thiab lwm yam. Vim tias ethylene oxide yog flammable thiab muaj ntau qhov sib txawv ntawm cov khoom tawg hauv huab cua, nws qee zaum siv ua cov roj ntawm cov roj gasification tawg foob pob. Cov khoom sib xyaw ua rau muaj kev phom sij yog carbon monoxide thiab carbon dioxide. Feem ntau ntawm ethylene oxide yog siv los ua lwm yam tshuaj, feem ntau yog ethylene glycol. Ethylene oxide yog flammable thiab tawg, thiab nws tsis yooj yim rau kev thauj mus los ntev, yog li nws muaj cov yam ntxwv hauv cheeb tsam muaj zog.

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.

② cov khoom siv tshuaj lom neeg yooj yim:

Ethylene oxide feem ntau yog siv los ua ethylene glycol (cov khoom siv raw rau polyester fiber), cov tshuaj ntxuav hluavtaws, cov tshuaj surfactants tsis-ionic, antifreeze, emulsifiers, thiab cov khoom ethylene glycol. Nws kuj tseem siv los tsim cov yas, cov roj nplua nyeem, roj hmab thiab yas, thiab lwm yam.

2019 Tuam Tshoj Tsim TshiabEthylene Oxide nrog CO2 Gas SterilizationTxawm hais tias muaj lub cib fim tas mus li, tam sim no peb tau tsim kev sib raug zoo nrog ntau tus tub luam txawv teb chaws, xws li cov neeg los ntawm Virginia. Peb ntseeg siab tias cov khoom lag luam ntawm lub tshuab luam ntawv t-shirt feem ntau zoo vim muaj ntau tus neeg muaj nws qhov zoo thiab tus nqi.
