Te whakataki i ngā rauemi noa mō ngā putea tākai korehau
Ngā putea tākai korehaui roto i tā tātou whakamahinga o ia rā, he tino teitei te auau o te whakamahi, he maha ngā whānau ka whakamahi Kete Korehaungā pēke tawhito hei tākai kai kia roa ake ai te ora o te kai. Ka pā tika te rauemi o te pēke korehau ki tōna hou, i te whakaaturanga korehau e whai ake nei ka ako tātou mō ngā rauemi me ngā āhuatanga o te pēke korehau.
Ko ngā rauemi tākai korehau kai e whakamahia whānuitia ana ko ēnei ngā kāwai e whai ake nei:
1, polyester ngā putea korehau:
Ko te polyester he kupu whānui mō ngā polymer i whiwhihia mā te polyol me te polyacid polycondensation. Ko te tikanga matua ko te polyethylene terephthalate (PET). Ko te putea korehau polyester (PET) he putea korehau kanapa, kāore he tae, he mārama, he mea hanga ki te polyethylene terephthalate hei rauemi mata, mā te whakamahi i te tikanga extrusion ki roto i te pepa matotoru, kātahi ka hangaia ki te rauemi putea korehau mā te totoro rua-aronga. He tino pai ngā āhuatanga miihini, he pakari teitei, he pakeke me te pakari, he ātete ki te poka, he ātete ki te waku, he ātete ki te pāmahana teitei me te iti, he ātete matū, he ātete ki te hinu, he ātete ki te hau me te pupuri reka pai, ko tētahi o ngā papa putea korehau hiato e whakamahia whānuitia ana. He mea whakamahi noa hei hanga i te paparanga o waho o ngā rauemi takai korohū, he pai ake te mahi pēhanga.
2, putea korehau nairona:
He tino pakari te putea korehau nairona (PA), he mārama, he kanapa, he kaha te kume, he kaha te kume, he pai hoki te ātete ki te wera, ki te makariri, ki te hinu me te ātete ki ngā whakarewa waro, he ātete ki te pakū, he pai te ātete ki ngā wero, ā, he ngawari ake, he pai te arai hāora, he pai mō te tākai i ngā taonga pakeke, pērā i te kai hinuhinu, ngā hua mīti, ngā kai parai, ngā kai kua tākai korehau, ngā kai tunu kai, me ētahi atu.
I runga i te nairona Ngā Pēke Korehau ka taea te ahu mai i ngā putea hiato nairona mahi teitei ake me ngā putea korehau maha-apa i whakaputahia tahitia.
Ko ngā putea hiato nairona te nuinga o te wā he mea tito mai i te PET/PE, PVC/PE, NY/PVDC, PE/PVDC, PP/PVDC, ko te rerekētanga matua i waenga i te putea whakakotahi ā, ko te tukanga he mea hanga i te papa, te piripiri whakapiri, ngā rauemi ārai, ngā rauemi hiri wera, ngā paninga tā me te tiaki me ētahi atu wāhanga.
Ko te wāhanga matua o te pēke korehau maha-apa he nairona, he mea hanga ki te PA, EVOH me te PE, PP, TIE me ētahi atu kapia, e whakamahi ana i te hanganga whakakotahi ōrite, āhua kore rānei. I te hononga o PA me EVOH, ehara i te mea ka tino whakapai ake i te kiriata maha-apa i runga i te arai hāora me te reka, te kaha o te kiri hiato, te ātete ki te taiao me te roa o te rokiroki hou. Nā te kore o te parahanga, te arai teitei, te mahi kaha, te utu iti, te ōwehenga kaha iti, te kaha teitei, te hanganga ngāwari me ētahi atu, ka kore e parahanga te tukanga whakaputa rauemi tākai kai.
3, Pēke korehau PE:
Ko te Polyethylene (polyethylene, poto PE) he kapia kirihou wera i hangaia mā te whakakotahitanga o te ethylene. He mārama ake i te nairona, he mārō te āhua, he pakarukaru te tangi, he pai rawa atu te ārai hau, te ārai hinu me te pupuri kakara. Kāore e pai mō te whakamahinga pāmahana teitei me te pouaka whakamātao, ā, he iti ake te utu i te nairona. He mea whakamahi whānuitia mō te rauemi putea korehau noa, kāore he whakaritenga motuhake.
4, putea korehau pepa konumohe:
He pēke korehau whakakotahi konumohe-kirihou (PET/AL/PE, PET/NY/AL/PE, PET/NY/AL/CPP rānei), ko te wāhanga matua he pepa konumohe, he mā, he hiriwa-mā, he ārai-kanapa, he pai te ārai, he hiri wera, he ārai hurihuri, he ātete pāmahana teitei, he ātete pāmahana iti, he ātete hinu, he pupuri kakara; kāore he paitini, kāore hoki he reka; he ngawari me ētahi atu āhuatanga. He pai mō ngā mīhini me ngā taputapu nui, ngā rauemi mata matū, ngā takawaenga rongoā, te ātete makuku, te mārama, te takai korehau. Neke atu i te whā-paparanga te hanganga, he pai te mahi ārai wai me te hāora. He whānuitia te whakamahinga o te pēke korehau pepa konumohe i roto i te kai, te hikohiko, te matū me ētahi atu ahumahi, nā te mea he nui ake te utu o te pepa konumohe, nō reira ka nui ake te utu o te korehau.
Ko te whakaaturanga korehau i runga ake nei kua whakarāpopototia i runga i te ngā putea tākai korehau Ngā rauemi me ngā āhuatanga e whakamahia whānuitia ana o te whakataki, e whakapono ana ahau i muri i te pānui i te maha o ngā hoa i roto i te whiriwhiri i ā rātou ake putea tākai hua ka whai māramatanga whānui mō taua mea. Mēnā kei te hiahia koe ki te mōhio atu ki ētahi atu kōrero, nau mai ki te kōrero mai ki a mātou.
