Imixube ye-Ethylene Oxide kunye neCarbon Dioxide

Iiparameter zobugcisa

I-ethylene oxide yenye yezona ether zilula kakhulu. Yikhompawundi ye-heterocyclic. Ifomyula yayo yekhemikhali yi-C2H4O. Yi-carcinogen enobuthi kwaye yimveliso ebalulekileyo ye-petrochemical. Iipropati zekhemikhali ze-ethylene oxide zisebenza kakhulu. Ingadlula kwiimpendulo zokongeza i-ring-opening kunye neekhompawundi ezininzi kwaye inokunciphisa i-silver nitrate. Kulula ukuyi-polymer emva kokuba ifudunyeziwe kwaye inokubola xa kukho iityuwa zesinyithi okanye ioksijini. I-ethylene oxide lulwelo olungenambala nolucacileyo kubushushu obuphantsi, kwaye yigesi engenambala enevumba elimnandi le-ether kubushushu obuqhelekileyo. Uxinzelelo lomphunga wegesi luphezulu, lufikelela kwi-141kPa kwi-30°C. Olu xinzelelo lomphunga luphezulu lumisela i-epoxy. Amandla anamandla okungena ngexesha lokufutha kunye nokubulala iintsholongwane nge-ethane. I-ethylene oxide inefuthe le-bactericidal, ayibolisi kwisinyithi, ayinavumba lishiyekileyo, kwaye inokubulala iintsholongwane (kunye nee-endospores zayo), ii-molds kunye ne-fungi, ngoko ke ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakumelana nokubulala iintsholongwane kubushushu obuphezulu. I-ethylene oxide sisibulali-ntsholongwane sekhemikhali sesizukulwana sesibini emva kwe-formaldehyde. Isesesinye sezona zibulali-ntsholongwane zibandayo zibalaseleyo. Ikwayeyona ndlela iphambili yokubulala iintsholongwane ezine ezikumgangatho ophantsi (i-plasma yobushushu obuphantsi, umphunga we-formaldehyde wobushushu obuphantsi, i-ethylene oxide). , I-Glutaraldehyde) ilungu elibaluleke kakhulu. Ngokwesiqhelo sebenzisa i-ethylene oxide-carbon dioxide (umlinganiselo wezi zimbini yi-90:10) okanye umxube we-ethylene oxide-dichlorodifluoromethane, osetyenziselwa kakhulu ukubulala iintsholongwane kwizibhedlele nakwizixhobo ezichanekileyo. I-ethylene oxide iyatsha kwaye iyaqhuma, kwaye iipropati zayo zeekhemikhali ziyasebenza kakhulu. Ingadlula kwiimpendulo zokongeza i-ring-opening kunye neekhompawundi ezininzi. Akulula ukuyithutha kumgama omde, ngoko ke ineempawu ezinamandla zengingqi. Amanyathelo okugcina: Gcina kwindawo yokugcina epholileyo, enomoya. Gcina kude nomlilo kunye nemithombo yobushushu. Kuphephe ukukhanya. Ubushushu bokugcina akufuneki budlule kwi-30°C. Kufuneka igcinwe ngokwahlukileyo kwi-asidi, i-alkalis, i-alcohols, kunye neekhemikhali ezityiwayo, kwaye uphephe ukugcina okuxutyiweyo. Sebenzisa izibane ezithintela ukuqhuma kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini nezixhobo ezinokuba neentlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Ukubulala iintsholongwane:

I-ethylene oxide inefuthe lokubulala iintsholongwane, ayibolisi iintsimbi, ayinavumba lishiyekileyo, kwaye inokubulala iintsholongwane (kunye nee-endospores zayo), ii-molds kunye ne-fungi, ngoko ke ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakumelana nokubulala iintsholongwane kubushushu obuphezulu.
