Kua roa te whakamahinga o te ethylene oxide (EO) mō te patu huakita me te whakahoromata, ā, koinei anake te matū whakahoromata hau e mōhiotia ana e te ao ko te mea tino pono. I mua,waikura etirenei whakamahia nuitia mō te patu huakita me te whakahoromata i te tauine ahumahi. Nā te whanaketanga o te hangarau ahumahi hou me te aunoatanga me te hangarau atamai, ka taea te whakamahi haumaru i te hangarau whakahoromata ethylene oxide i roto i ngā whare hauora hei whakahoromata i ngā taputapu hauora tino tika e wehi ana i te wera me te makuku.

Ngā āhuatanga o te waikura etilena

Waikura etirenaKo te tuarua o ngā whakatipuranga o ngā patu huakita matū i muri i te formaldehyde. Ko tētahi tonu o ngā patu huakita makariri pai rawa atu, ā, ko te mema nui rawa atu o ngā hangarau patu huakita pāmahana-iti matua e whā.

He matū epoxy māmā noa te waikura ethylene. He hau kore tae i te pāmahana rūma me te pēhanga. He taumaha ake i te hau, ā, he kakara ether kakara. He mura, he pahū hoki te waikura ethylene. Ina kei roto i te hau te 3% ki te 80%waikura etirene, ka puta he hau pahū, ka mura, ka pahū rānei ina pā ki te mura tuwhera. Ko te kukū o te ethylene oxide e whakamahia whānuitia ana mō te patu huakita me te whakahoromata he 400 ki te 800 mg/L, kei roto i te awhe kukū mura me te pahū i te rangi, nō reira me tūpato te whakamahi.

Ka taea te whakaranu i te waikura ethylene me ngā hau kore mahi pērā i tehauhā waroi te ōwehenga o te 1:9 hei hanga i tētahi ranunga ātete-pahū, he mea haumaru ake hoki mō te patu huakita me te whakahoromata.Waikura etirenaka taea te whakapūhui, engari i te nuinga o te wā he puhoi te whakapūhui, ā, ka puta te nuinga i roto i te āhua wai. I roto i ngā ranunga o te waikura etilena me te hauhā waro, ngā hauwaiwai fluorinated rānei, ka puhoi ake te whakapūhui, ā, he iti ake te tūponotanga o te pahū o ngā pūhui totoka.

Te Mātāpono o te Whakahoromatatanga o te Ethylene Oxide

1. Te Whakakākitanga

Te tikanga mahi awaikura etireneKo te nuinga o te wā, ko te alkylation te mea nui mō te patu i ngā momo moroiti. Ko ngā wāhi mahi ko te sulfhydryl (-SH), te amino (-NH2), te hydroxyl (-COOH) me te hydroxyl (-OH) i roto i ngā ngota pūmua me ngā waikawa karihi. Ka taea e te ethylene oxide te meinga i ēnei rōpū kia pāngia e ngā tauhohenga alkylation, ka kore ai e mahi ēnei macromolecules koiora o ngā moroiti, ā, ka mate ngā moroiti.

2. Ārai i te mahi a ngā whākōkī koiora

Ka taea e te ethylene oxide te aukati i te mahi a ngā whākōkī o ngā moroiti, pērā i te phosphate dehydrogenase, te cholinesterase me ētahi atu oxidases, ka whakaroa i te otinga o ngā tukanga pākia noa o ngā moroiti, ā, ka arahi atu ki tō rātou matenga.

3. Te pānga whakamate ki ngā moroiti

Ngā mea e ruawaikura etireneHe kaha te pānga patu moroiti o te wai me te hau. Ki te whakataurite, he kaha ake te pānga patu moroiti o te hau, ā, ko tōna hau te nuinga o te wā e whakamahia ana mō te patu huakita me te whakahoromata.

He tino whai hua te waikura ethylene, he rongoā whānui-whānui tōna, ā, he kaha tōna pānga ki te whakamate me te whakakore i ngā tinana whakatipu huakita, ngā pua huakita, ngā harore, me ngā huaketo. Ina pā te waikura ethylene ki ngā moroiti, engari he nui te wai kei roto i ngā moroiti, ko te tauhohenga i waenga i te waikura ethylene me ngā moroiti he tauhohenga tuatahi noa iho. Ko te horopeta e whakakore ana i ngā moroiti parakore kua whakatipuria, ko te pihi tauhohenga he rārangi tika i runga i te uara haurua-rōkarithmic.

Te whānuitanga o te whakamahinga o te whakahoromata ethylene oxide

Waikura etirenaKāore e kino ngā taonga kua whakahoromatatia, ā, he kaha te uru ki roto. Ko te nuinga o ngā taonga kāore e tika ana mō te whakahoromata mā ngā tikanga whānui ka taea te patu huakita me te whakahoromata ki te ethylene oxide. Ka taea te whakamahi mō te whakahoromata o ngā hua whakarewa, ngā endoscope, ngā dialyzer me ngā taputapu hauora whakakorekore, te patu huakita ahumahi me te whakahoromata o ngā momo papanga, ngā hua kirihou, me te patu huakita o ngā taonga i ngā wāhi mate urutā (pērā i ngā papanga muka matū, te hiako, te pepa, ngā tuhinga, me ngā peita hinu).

Kāore te waikura ethylene e kino ki ngā mea kua whakahoromatatia, ā, he kaha te uru ki roto. Ko te nuinga o ngā taonga kāore e pai mō te whakahoromata mā ngā tikanga whānui, ka taea te patu huakita me te whakahoromata ki te waikura ethylene. Ka taea te whakamahi mō te whakahoromata o ngā hua whakarewa, ngā endoscope, ngā dialyzer me ngā taputapu hauora whakakorekore, te patu huakita ahumahi me te whakahoromata o ngā momo papanga, ngā hua kirihou, me te patu huakita o ngā taonga i ngā wāhi mate urutā (pērā i ngā papanga muka matū, te hiako, te pepa, ngā tuhinga, me ngā peita hinu).

Ngā āhuatanga e pā ana ki te pānga o te whakahoromata owaikura etirene

He maha ngā āhuatanga e pāngia ana e te pānga whakahoromata o te ethylene oxide. Hei whakatutuki i te pānga whakahoromata pai rawa atu, mā te whakahaere pai i ngā āhuatanga maha anake ka taea ai e ia te mahi pai ki te patu i ngā moroiti me te whakatutuki i tana kaupapa o te patu huakita me te whakahoromata. Ko ngā āhuatanga matua e pā ana ki te pānga whakahoromata ko: te kukū, te pāmahana, te haumākū whanaunga, te wā mahi, me ētahi atu.
