Ngā Ranunga o te Waikura Ethylene me te Hauhā Waro

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 (plasma pāmahana iti, te mamaoa formaldehyde pāmahana iti, te ethylene oxide). , Glutaraldehyde) te mema nui rawa atu. Ko te ethylene oxide-waro hauhā (ko te ōwehenga o ngā mea e rua he 90:10) te ranunga ethylene oxide-dichlorodifluoromethane rānei, e whakamahia ana mō te patu huakita i ngā hōhipera me ngā taputapu tino tika. He mura, he pahū te ethylene oxide, ā, he tino kaha ōna āhuatanga matū. Ka taea e ia te uru atu ki ngā tauhohenga tāpiri mowhiti-tuwhera me te maha o ngā matū. Ehara i te mea ngāwari ki te kawe i ngā tawhiti roa, nō reira he kaha ngā āhuatanga ā-rohe. Ngā whakatūpato rokiroki: Penapena ki roto i te whare putunga hauhautanga, hauhautanga. Puritia kia matara atu i te ahi me ngā pūtake wera. Āraia te mārama. Kaua te pāmahana rokiroki e neke ake i te 30°C. Me penapena motuhake mai i ngā waikawa, ngā kawakore, ngā waipiro, me ngā matū kai, ā, karohia te rokiroki whakauru. Whakamahia ngā rama ātete-pahūtanga me ngā whakaurunga hauhautanga. Kāore e whakaaetia te whakamahi i ngā taputapu me ngā taputapu miihini e ngāwari ana ki te mura. Me whai taputapu maimoatanga ohorere turuturu te wāhi rokiroki.

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.
