Okiside ya Ethylene (EO) imaze igihe kinini ikoreshwa mu kwanduza no kuboneza urubyaro kandi ni yo yonyine ya gazi ya chimique yemewe n’isi yose ko yizewe cyane. Kera,okisideyakoreshwaga cyane cyane mu kwangiza inganda no kwanduza. Hamwe niterambere ryiterambere rya tekinoloji yinganda zigezweho no gukoresha ibyuma byikoranabuhanga hamwe nubuhanga bwubwenge, tekinoroji ya Ethylene oxyde sterilisation irashobora gukoreshwa neza mubigo byubuvuzi kugirango ihagarike ibikoresho byubuvuzi byuzuye bitinya ubushyuhe nubushuhe.

Ibiranga okiside ya Ethylene

Okiside ya Ethyleneni igisekuru cya kabiri cyimiti yica udukoko nyuma ya formaldehyde. Biracyari imwe mu miti yica udukoko twiza kandi ni umunyamuryango wingenzi muri tekinoroji enye zingenzi zo mu rwego rwo hasi.

Ethylene oxyde ni ibintu byoroshye bya epoxy. Ni gaze itagira ibara mubushyuhe bwicyumba nigitutu. Iremereye kuruta umwuka kandi ifite impumuro nziza ya ether. Okiside ya Ethylene irashya kandi iraturika. Iyo umwuka urimo 3% kugeza 80%okiside, gaze ivanze iturika, irashya cyangwa igaturika iyo ihuye numuriro ufunguye. Ubusanzwe ikoreshwa rya Ethylene oxyde yo kwanduza no kwanduza ni 400 kugeza 800 mg / L, iri mu kirere cyaka kandi giturika mu kirere, bityo rero igomba gukoreshwa ubwitonzi.

Okiside ya Ethylene irashobora kuvangwa na gaze ya inert nkaDioxyde de carboneku kigereranyo cya 1: 9 kugirango habeho imvange idashobora guturika, ikaba ifite umutekano mukwanduza no kuboneza urubyaro.Okiside ya Ethyleneirashobora gukora polymerize, ariko mubisanzwe polymerisation iratinda kandi ahanini ibaho mumazi. Mu mvange ya okiside ya Ethylene na karuboni ya karubone cyangwa hydrocarbone ya fluor, polymerisation ibaho gahoro gahoro kandi polymer zikomeye ntizishobora guturika.

Ihame rya Ethylene Oxide Sterilisation

1. Alkylation

Uburyo bwibikorwa byaokisidemukwica mikorobe zitandukanye ni alkylation. Ahantu ho gukorera ni sulfhydryl (-SH), amino (-NH2), hydroxyl (-COOH) na hydroxyl (-OH) muri poroteyine na molekile ya aside nucleique. Okiside ya Ethylene irashobora gutuma ayo matsinda agira reaction ya alkylation, bigatuma iyi macromolecules yibinyabuzima ya mikorobe idakora, bityo ikica mikorobe.

2. Kubuza ibikorwa byimisemburo yibinyabuzima

Okiside ya Ethylene irashobora guhagarika ibikorwa byimisemburo itandukanye ya mikorobe, nka fosifate dehydrogenase, cholinesterase nizindi okiside, bikabuza kurangiza inzira zisanzwe ziterwa na mikorobe kandi bikabapfa.

3. Kwica ingaruka kuri mikorobe

Byombiokisideamazi na gaze bifite ingaruka zikomeye za mikorobe. Mugereranije, ingaruka za mikorobe ya gaze irakomeye, kandi gaze yayo muri rusange ikoreshwa mukwangiza no kuboneza urubyaro.

Okiside ya Ethylene ningirakamaro cyane mugari ifite imbaraga zo kwica no kudakora kumubiri ukwirakwiza za bagiteri, spore ya bagiteri, fungi, na virusi. Iyo okiside ya Ethylene ihuye na mikorobe, ariko mikorobe irimo amazi ahagije, reaction iri hagati ya okiside ya Ethylene na mikorobe ni ibintu bisanzwe byambere. Igipimo kidakora mikorobe yumuco itunganijwe neza, reaction reaction ni umurongo ugororotse kuri kimwe cya kabiri cya logarithmic.

Ikoreshwa rya Ethylene oxyde sterilisation

Okiside ya Ethylenentabwo yangiza ibintu byangiritse kandi bifite kwinjira cyane. Ibintu byinshi bidakwiriye guhindurwa hakoreshejwe uburyo rusange birashobora kwanduzwa no kwanduzwa na okiside ya Ethylene. Irashobora gukoreshwa muguhagarika ibicuruzwa byibyuma, endoskopi, dialyse hamwe nibikoresho byubuvuzi bikoreshwa, kwanduza inganda no kwanduza imyenda itandukanye, ibicuruzwa bya pulasitike, no kwanduza ibintu mubice by’ibyorezo byanduye (nk'imyenda ya fibre fibre, uruhu, impapuro, inyandiko, n'amashusho y'amavuta).

Okiside ya Ethylene ntabwo yangiza ibintu byangiritse kandi ifite kwinjira cyane. Ibintu byinshi bidakwiriye guhindurwa hakoreshejwe uburyo rusange birashobora kwanduzwa no kwanduzwa na okiside ya Ethylene. Irashobora gukoreshwa muguhagarika ibicuruzwa byibyuma, endoskopi, dialyse hamwe nibikoresho byubuvuzi bikoreshwa, kwanduza inganda no kwanduza imyenda itandukanye, ibicuruzwa bya pulasitike, no kwanduza ibintu mubice by’ibyorezo byanduye (nk'imyenda ya fibre fibre, uruhu, impapuro, inyandiko, n'amashusho y'amavuta).

Ibintu bigira ingaruka kuri sterilisation yaokiside

Ingaruka ya sterilisation ya okiside ya Ethylene iterwa nibintu byinshi. Kugirango ugere ku ngaruka nziza yo kuboneza urubyaro, gusa mu kugenzura neza ibintu bitandukanye birashobora kugira uruhare runini mu kwica mikorobe kandi bikagera ku ntego yo kwanduza no kuboneza urubyaro. Ibintu byingenzi bigira ingaruka kuri sterisizione ni: kwibanda, ubushyuhe, ubushuhe bugereranije, igihe cyibikorwa, nibindi.
