E rua ngā wāhanga o ngā rauemi o ngā taputapu hauora: ngā rauemi whakarewa me ngā rauemi pūmua. He pumau ngā āhuatanga o ngā rauemi whakarewa, ā, he pai te manawanui ki ngā momo tikanga whakahoromata. Nō reira, he maha ngā wā ka whakaarohia te manawanui o ngā rauemi pūmua i te wā e whiriwhiri ana i ngā tikanga whakahoromata. Ko ngā rauemi pūmua hauora e whakamahia whānuitia ana mō ngā taputapu hauora ko te polyethylene, te polyvinyl chloride, te polypropylene, te polyester, me ētahi atu, ā, he pai te urutau o ēnei rauemi katoa ki ngā āhuatanga taiao.te waikura etirene (EO)tikanga whakahoromata.

EOhe rongoā whakahoromata whānui e taea ai te patu i ngā momo moroiti i te pāmahana rūma, tae atu ki ngā pua, ngā huakita kohi, ngā huakita, ngā huaketo, ngā harore, me ētahi atu. I te pāmahana rūma me te pēhanga,EOHe hau kore tae, he taumaha ake i te hau, ā, he kakara etera kakara. Ina iti iho te pāmahana i te 10.8℃, ka rewa te hau, ka huri hei wai mārama kore tae i ngā pāmahana iti. Ka taea te whakaranu ki te wai i roto i tētahi ōwehenga, ā, ka taea te rewa ki roto i ngā whakarewa waro e whakamahia whānuitia ana. He nui te pēhanga kohu o te EO, nō reira he kaha te uru ki roto i ngā mea kua whakahoromatatia, ka taea te uru ki ngā pūwero iti, ka tae ki te wāhanga hohonu o ngā mea, he mea pai mō te whakahoromatatanga tino pai.

Te Pāmahana Whakahoromata

I roto i tewaikura etireneI roto i te mīhini whakahoromata, ka kaha ake te nekehanga o ngā ngota ethylene oxide i te pikinga o te pāmahana, ā, he mea pai tēnei mō tōna taenga atu ki ngā wāhanga e rite ana, me te whakapai ake i te pānga whakahoromata. Heoi, i roto i te tukanga whakaputa tuturu, kāore e taea te whakanui ake i te pāmahana whakahoromata mō ake tonu atu. Haunga te whakaaro ki ngā utu pūngao, te mahi a ngā taputapu, me ētahi atu, me whai whakaaro anō hoki ki te pānga o te pāmahana ki te mahi a te hua. Mā te pāmahana tino tiketike ka tere ake te pirau o ngā rauemi polymer, ka hua ake he hua kore tohu, he poto rānei te roa o te mahi, me ētahi atu.Nō reira, ko te pāmahana whakahoromata o te ethylene oxide he 30-60℃ te tikanga.

Te haumākū ā-whanaunga

He wāhi whai wāhi te wai ki tewaikura etirenete tauhohenga whakahoromata. Mā te whakarite i tētahi haumākū ōrite i roto i te whakahoromata ka taea e te ethylene oxide me ngā moroiti te whai i tētahi tauhohenga alkylation hei whakatutuki i te kaupapa o te whakahoromata. I taua wā anō, ka taea hoki e te noho mai o te wai te whakateretere i te pikinga o te pāmahana i roto i te whakahoromata me te whakatairanga i te tohatoha ōrite o te pūngao wera.Ko te haumākū whanaunga owaikura etireneko te whakahoromata he 40%-80%.Ina iti iho i te 30%, he māmā noa te korenga o te whakahoromata.

Te arotahi

I muri i te whakatau i te pāmahana whakahoromata me te haumākū whanaunga, kawaikura etireneKo te kukū me te whai huatanga o te whakahoromata e whakaatu ana i te tauhohenga nekeneke o te raupapa tuatahi, arā, ka piki te tere o te tauhohenga me te pikinga o te kukū o te ethylene oxide i roto i te whakahoromata. Heoi, kāore tōna tipu i te mutunga kore.Ina neke atu te pāmahana i te 37°C, ā, ina nui ake te kukū o te waikura etilena i te 884 mg/L, ka uru ki te āhua tauhohenga kore-raupapa., me tewaikura etirenehe iti noa te pānga o te kukū ki te tere o te tauhohenga.

Wā Mahi

I te wā e whakamanahia ana te whakahoromata, ka whakamahia te tikanga haurua-huringa hei whakatau i te wā whakahoromata. Ko te tikanga haurua-huringa ko te wā e kore e rerekē ngā tawhā kē atu i tua atu i te wā, ka hauruahia te wā mahi kia tae rā anō ki te wā poto rawa atu mō ngā mea kua whakahoromata kia tae ki te āhua whakahoromata. E toru ngā wā ka tuaruatia te whakamātautau whakahoromata. Mena ka taea te whakatutuki i te pānga whakahoromata, ka taea te whakatau hei haurua-huringa. Hei whakarite i te pānga whakahoromata,ko te wā whakahoromata tuturu kua whakaritea me rua pea te iti rawa o te haurua huringa, engari me tatau te wā mahi mai i te wā e pā ana te pāmahana, te haumākū whanaunga,waikura etireneKo te kukū me ētahi atu āhuatanga i roto i te mīhini whakahoromata e tutuki ai ngā whakaritenga whakahoromata.

Ngā rauemi tākai

He rerekē ngā whakaritenga mō ngā rauemi tākai mō ngā tikanga whakahoromata rerekē. Me whai whakaaro ki te āheinga o ngā rauemi tākai e whakamahia ana ki te tukanga whakahoromata. Ko ngā rauemi tākai pai, inā koa ko ngā rauemi tākai iti rawa, e pā tika ana ki te pānga whakahoromata o te ethylene oxide. I te wā e whiriwhiri ana i ngā rauemi tākai, me whai whakaaro ki ngā āhuatanga pēnei i te ātete ki te whakahoromata, te urunga o te hau, me ngā āhuatanga patu huakita.Waikura etirenaKo te whakahoromata me whai āhua uruhanga hau ngā rauemi tākai.
