Ka whakawhirinaki mātou ki te whakaaro rautaki, te whakahou tonu i ngā wāhanga katoa, ngā whanaketanga hangarau, me te whai wāhi tika ki ā mātou kaimahi e whai wāhi tika ana ki tā mātou angitu mō te hau whakamahana EO pai rawa atu i Haina, te hau Ethylene Oxide me te hau ranunga CO2. Mena kei te rapu koe i tētahi kaiwhakarato kounga teitei, tuku tere, ratonga pai rawa atu me te utu pai i Haina mō te hononga pakihi roa, ko mātou te whiringa pai rawa atu māu.
Ka whakawhirinaki mātou ki te whakaaro rautaki, ki te whakahou tonu i ngā wāhanga katoa, ki ngā whanaketanga hangarau, ā, ki ā mātou kaimahi hoki e whai wāhi tika ana ki tō mātou angitu mōHaina Eo me te hau CO2 me Eto me te hau CO2, Kei te mahi tā mātou kamupene i runga i te mātāpono whakahaere o te "pūmautanga, te mahi tahi e waihangahia ana, te aro ki te tangata, te mahi tahi e whai hua ana ki te katoa". Ko tā mātou e tumanako nei ka taea e mātou te whai hononga pai ki ngā kaipakihi o te ao katoa.

Ngā tawhā hangarau

Ko te waikura ethylene tētahi o ngā ether porowhita māmā rawa. He matū heterocyclic. Ko tōna tauira matū ko C2H4O. He carcinogen paitini, he hua matū hinu nui hoki. He tino kaha ngā āhuatanga matū o te waikura ethylene. Ka taea e ia te whai i ngā tauhohenga tāpiri whakatuwhera-mowhiti me te maha o ngā matū, ā, ka taea te whakaiti i te nitaita hiriwa. He ngāwari te whakakotahi i muri i te wera, ā, ka taea te pirau i te aroaro o ngā tote whakarewa, o te hāora rānei. He wai mārama, kāore he tae o te waikura ethylene i te pāmahana iti, ā, he hau kāore he tae me te kakara ether i te pāmahana noa. He teitei te pēhanga kohu o te hau, e tae ana ki te 141kPa i te 30°C. Mā tēnei pēhanga kohu teitei ka whakatau i te kaha o te epoxy. He kaha te uru i te wā e whakapūpū ana i te ethane me te patu huakita. He pānga patu huakita te waikura ethylene, kāore e waikura ki ngā whakarewa, kāore he kakara toenga, ā, ka taea te patu i ngā huakita (me ōna endospores), ngā pokepokea ai me ngā harore, nō reira ka taea te whakamahi hei patu huakita i ētahi taonga me ngā rauemi kāore e taea te tu atu i te patu huakita pāmahana teitei. Ko te waikura ethylene te patu huakita matū tuarua o te whakatupuranga i muri i te formaldehyde. Ko tētahi tonu o ngā patu huakita makariri pai rawa atu. Koia anō hoki ngā hangarau patu huakita pāmahana-iti matua e whā (te plasma pāmahana-iti, te mamaoa formaldehyde pāmahana-iti, te waikura ethylene). , Glutaraldehyde) te mema tino nui. Ka whakamahia hoki te waikura ethylene ki te hanga i ētahi atu whakarewa (pēnei i te cellosolve, me ētahi atu), ngā wairewa, ngā matū horoi kore-ionic, ngā hopi hangai, ngā ārai hukapapa, ngā patu huakita, ngā whakapakeke me ngā mea hanga kirihou, me ētahi atu. Nā te mea he mura te waikura ethylene, ā, he whānui te awhe kukū pahūtanga i te rangi, ka whakamahia i ētahi wā hei wāhanga wahie o ngā poma pahū whakapūngao wahie. Ko ngā hua tahunga kino ko te waro hauhā me te waro hauhā. Ko te nuinga o te waikura ethylene e whakamahia ana ki te hanga i ētahi atu matū, ko te ethylene glycol te nuinga. He mura te waikura ethylene, ā, he pahū, ā, ehara i te mea ngāwari ki te kawe i ngā tawhiti roa, nō reira he kaha ngā āhuatanga ā-rohe.

Taupānga:

①Te whakahoromata:

He pānga patu huakita tō te ethylene oxide, kāore e waikura ki ngā konganuku, kāore he haunga toenga, ā, ka taea te patu i ngā huakita (me ōna endospore), i ngā harore me ngā pokepokea ai, nō reira ka taea te whakamahi hei patu huakita i ētahi taonga me ngā rauemi kāore e taea te tu atu i te patu huakita i te pāmahana tiketike.

② rauemi mata matū taketake:

Ko te ethylene oxide te mea e whakamahia nuitia ana hei hanga i te ethylene glycol (he rauemi mata mō te muka polyester), ngā hopi horoi hangai, ngā surfactants kore-ionic, ngā anti-freeze, ngā emulsifiers, me ngā hua ethylene glycol. E whakamahia ana hoki hei hanga plasticizers, hinu whakahinuhinu, rapa me ngā kirihou, me ētahi atu.

Mōkihi noa:
