Ethylene oxide & Carbon Dioxide Imixube

Iiparamitha zobugcisa

I-ethylene oxide yenye yezona zilula ze-ethers ze-cyclic. Yikhompawundi ye-heterocyclic. Indlela yayo yeekhemikhali yiC2H4O. Iyi-carcinogen enetyhefu kunye nemveliso ebalulekileyo yepetrochemical. Iimpawu zeekhemikhali ze-ethylene oxide zisebenza kakhulu. Inokungena kwiimpendulo zokongezwa kweringi kunye neekhompawundi ezininzi kwaye inokunciphisa i-nitrate yesilivere. Kulula ukwenza i-polymerize emva kokufudumala kwaye inokubola phambi kweetyuwa zetsimbi okanye i-oxygen. I-ethylene oxide lulwelo olungenambala noluselubala kwiqondo lobushushu eliphantsi, kunye nerhasi engenambala enevumba elibukhali leether kubushushu obuqhelekileyo. Uxinzelelo lomphunga werhasi luphezulu, lufikelela kwi-141kPa kuma-30°C. Olu xinzelelo luphezulu lomphunga lumisela i-epoxy Amandla okungena anamandla ngexesha lokutshisa i-ethane kunye nokubulala iintsholongwane. I-Ethylene oxide inempembelelo ye-bactericidal, ayidliyo kwiintsimbi, ayinavumba elishiyekileyo, kwaye inokubulala ibhaktheriya (kunye ne-endospores yayo), i-molds kunye ne-fungi, ngoko ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakukwazi ukumelana nokushisa kwe-disinfection. . . I-Ethylene oxide sisibulala-ntsholongwane seekhemikhali sesizukulwana sesibini emva kwe-formaldehyde. Isesinye sezona zibulali ntsholongwane zibandayo. Ikwazezona teknoloji zine ziphambili zobushushu obuphantsi (iplasma yobushushu obuphantsi, ubushushu obuphantsi be-formaldehyde umphunga, i-ethylene oxide). , Glutaraldehyde) elona lungu libalulekileyo. Ngokuqhelekileyo sebenzisa i-ethylene oxide-carbon dioxide (umyinge wezo zimbini yi-90: 10) okanye i-ethylene oxide-dichlorodifluoromethane umxube, isetyenziselwa ukubulala iintsholongwane kwizibhedlele kunye nezixhobo ezichanekileyo. I-ethylene oxide iyatsha kwaye iyaqhuma, kwaye iimpawu zayo zemichiza zisebenza kakhulu. Inokungena kwiringi yokuvula iintshukumo zokudibanisa kunye neekhompawundi ezininzi. Akulula ukuthutha imigama emide, ngoko ke ineempawu eziqinileyo zengingqi. Amanyathelo okhuseleko: Gcina kwindawo epholileyo, nengena umoya. Zigcine kude nomlilo kunye nemithombo yobushushu. Kuphephe ukukhanya. Ubushushu bokugcina akufunekanga budlule kuma-30°C. Kufuneka igcinwe ngokwahlukileyo kwi-acids, i-alkalis, i-alcohol, kunye neekhemikhali ezidliwayo, kwaye ugweme ukugcinwa okuxubileyo. Sebenzisa izibane ezingagqabhukiyo kunye nezixhobo zokungenisa umoya. Akuvumelekanga ukusebenzisa izixhobo zoomatshini kunye nezixhobo ezixhomekeke kwiintlantsi. Indawo yokugcina kufuneka ixhotyiswe ngezixhobo zonyango olungxamisekileyo oluvuzayo.

Isicelo:

①Ukuvalwa:

I-Ethylene oxide inempembelelo ye-bactericidal, ayidliyo kwiintsimbi, ayinavumba elishiyekileyo, kwaye inokubulala ibhaktheriya (kunye ne-endospores yayo), i-molds kunye ne-fungi, ngoko ingasetyenziselwa ukubulala iintsholongwane kwezinye izinto kunye nezinto ezingenakukwazi ukumelana nokushisa kwe-disinfection. .
