Okuqhelekileyoi-ethylene oxideInkqubo yokubulala iintsholongwane isebenzisa inkqubo yokufunxa i-vacuum, ngokubanzi isebenzisa i-100% ye-ethylene oxide ecocekileyo okanye igesi exutyiweyo equlethe i-40% ukuya kwi-90%i-ethylene oxide(umzekelo: ixutywe neumoya omdakaokanye initrogen).

Iimpawu zeGesi ye-Ethylene Oxide

Ukubulala iintsholongwane kwi-ethylene oxide yindlela ethembekileyo yokubulala iintsholongwane kubushushu obuphantsi.I-ethylene oxideinesakhiwo sendandatho esingenazinzo esinamalungu amathathu kunye neempawu zayo ezincinci zemolekyuli, ezenza ukuba ingene kakhulu kwaye isebenze kwiikhemikhali.

I-ethylene oxide yigesi enobuthi etshayo neqhumayo eqala ukubumbana kumaqondo obushushu angaphezu kwama-40°C, ngoko ke kunzima ukuyigcina. Ukuphucula ukhuseleko,umoya omdakaokanye ezinye iigesi ezingasebenziyo zihlala zisetyenziswa njengezinto zokunciphisa ubushushu bokugcina.

Indlela yokubulala iintsholongwane ye-ethylene oxide kunye neempawu zayo

Umgaqo wei-ethylene oxideUkubulala iintsholongwane kwenzeka ikakhulu ngenxa yempendulo yayo ye-alkylation engeyiyo ethile kunye neeproteni ze-microbial, i-DNA kunye ne-RNA. Le mpendulo inokuthatha indawo yee-athomu ze-hydrogen ezingazinzanga kwiiproteni ze-microbial ukuze zenze iikhompawundi ezinamaqela e-hydroxyethyl, nto leyo ebangela ukuba iiproteni zilahlekelwe ngamaqela asabelayo azidingayo kwi-metabolism esisiseko, ngaloo ndlela zithintela iimpendulo eziqhelekileyo zeekhemikhali kunye ne-metabolism yeeproteni ze-bacterial, kwaye ekugqibeleni zikhokelele ekufeni kwee-microorganisms.

Iingenelo zokucoca igesi nge-ethylene oxide

1. Ukubulala iintsholongwane kungenziwa kumaqondo obushushu aphantsi, kwaye izinto ezinobuthathaka kumaqondo obushushu kunye nokufuma zinokucocwa.

2. Isebenza kuzo zonke iintsholongwane, kuquka zonke iintsholongwane ezikwiintsholongwane.

3. Amandla okungena aqinileyo, ukubulala iintsholongwane kungenziwa kwimeko epakishiweyo.

4. Akukho monakalo kwiintsimbi.

5. Ifanelekile ukubulala iintsholongwane kwizinto ezingamelaniyo nobushushu obuphezulu okanye imitha, njengezixhobo zonyango, iimveliso zeplastiki, kunye nezinto zokupakisha amayeza. Iimveliso zomgubo owomileyo azikhuthazwa ukubulala iintsholongwane kusetyenziswa le ndlela.
