Kei te piki haere te kitea o ngā raruraru taiao i te whanaketanga ōhanga, ā, he mahi nui te whakatutuki i te matū matomato i ēnei rā.
He hangarau hou whakaharahara te hangarau pahuka tino whakamīharo, ko ngā kaihoko pahuka e whakamahia ana i roto i te hangarau pahuka tino whakamīharo ko te nuinga o te waro hauhā tino whakamīharo (ScCO2) me te hauota tino whakahāngai (ScN2), e whakamahia ana ēnei e rua me te kore he taumahatanga ki te taiao.
I roto i ngā mahi hū, kei te hurihia e te Hangarau Foam Supercritical te umanga hū. Nā tēnei hangarau kua taea e ngā kaihanga hū te whakawhānui ake i ā rātou rauemi ki tua atu i ngā TPU, TPE, me te EVA tuku iho. Ināianei, ka taea hoki e rātou te whakamahi i ngā rauemi pēnei i te PEBAX, ETPU, me ētahi atu elastomers hei hanga hū me te urunga me te tautoko pai, he mama, he pakari, he whakamarie, he pai hoki mō te taiao.
Engari nā te whakamahinga o te hangarau pahuka supercritical hei whakaputa pahuka EVA, kua hurihia te huarahi e whakamahia ai tēnei rauemi e ngā umanga maha. Ka whakamahia e tēnei hangarau he huinga o te pēhanga teitei me te pāmahana hei hanga i tētahi pahuka he māmā, he pakari, ā, he tino ātete ki te pakaru me te pakaru. Ko te tukanga he werohanga i tētahi hau, pērā i te hauhā waro (ScCO2), ki roto i te wairewa wai o te kapia EVA me ētahi atu tāpiringa. Kātahi ka whakamahanahia te hau, ka pēhia kia tae ki te āhua tino kaha, ka tere te horapa o te hau, ka hanga he mirumiru iti. Kātahi ka mau ēnei mirumiru ki roto i te wairewa wai, ka hanga he pahuka he pai ake ngā āhuatanga ki te whakataurite ki ngā pahuka tuku iho. He tere ake, he māmā ake, he kaha ake, he pakari ake, he pai ake te whiriwhiri mō ngā momo tono. Hei tauira, mai i ngā hu e whakarato ana i te urunga me te tautoko mō ngā waewae ki ngā hua akuaku, ngā hua hākinakina whakangahau, ngā whāriki papa/yoga, ngā taonga takaro, ngā takai, ngā taputapu hauora, ngā taputapu tiaki, ngā hua kore-paheke wai, ngā panera photovoltaic, me ētahi atu... Ka whakamahia hoki i roto i ngā tono motuka me te rererangi hei whakarato i te whakamarumaru me te ārai oro.
Ngā Hangarau Rauemi Tauwhiro mō ngā Auahatanga i hangaia ki te pahuka EVA!
Heoi, ko te whakamahinga o te hangarau pahuka tino whakamīharo hei whakaputa rauemi EVA me aro ki te take o te hononga whakawhiti. He rārangi ngā mekameka ngota EVA, ā, me whai hanganga hononga whakawhiti hei raka i te hau. Ahakoa kei te hangaia kētia i roto i ngā hu me ētahi mara, kāore anō kia whakamahia i runga i te tauine nui. Ko te raru nui o te pahuka tino whakamīharo ko te iti rawa o te tere hua kua oti, iti iho i te 50%, ā, ka aukati i te whanaketanga o te pahuka tino whakamīharo.
I konatunatua te EVA ki te hangarau pahuka EVA hangarua 100% a Si-TPV, ka āwhina tēnei hangarau pahuka EVA ki te kawe i ngā hū ki te huarahi whakamarie me te pumau. Ehara i te mea ka taea anake te whakatutuki i te iti o te mātotoru me te pakari teitei engari he ātete pai ki te kakahu, he iti ake te tere whakaheke wera, he ōrite te tae, he tere hua oti teitei, he ngāwari te whakahaere, me te utu iti, Ki te whakataurite ki te pahuka supercritical.
I te mea ka nui haere ngā ahumahi e whakamahi ana i tēnei Whakarerekētanga Huka EVA Ngāwari Si-TPV me te hangarau EVA, ka kite pea tātou i ētahi atu whakamahinga auaha mō tēnei rauemi hou whakaharahara. Kāore te hou e herea noa ki te umanga hū ngohengohe tino māmā.
Mena kei te rapu koe i ngā otinga mō te pahuka EVA ngohengohe ngāwari, ka whakaitihia e te Kaiwhakatika te pēhanga o te pahuka EVA, te hangarau pahuka matū mō te pahuka EVA māmā, te Kaiwhakatika Pahuka EVA ngohengohe, ngā otinga rānei mō te pahuka tino matatau.
Tena koa whakapā mai ki a mātou, mō ētahi atu mōhiohio.
