Ngā pēke whakamahana pāmahana teiteimengā putea kohuahe mea hanga ēnei e rua ki ngā rauemi hiato, nōngā putea tākai hiatoKo ngā rauemi noa mō ngā putea kohua ko NY/CPE, NY/CPP, PET/CPE, PET/CPP, PET/PET/CPP, me ētahi atu. Ko ngā rauemi e whakamahia whānuitia ana mōte takai korohū me te tunu kaikei roto NY / CPP, PET / CPP, NY / NY / CPP, PET / PET / CPP, PET / AL / CPP, PET / AL / NY / CPP, etc.
Ko ngā hanganga pēke korohū me te pēke tunu kai he paparanga o waho o te kiriata polyester hei whakapakari; ko te paparanga o waenganui he mea hanga ki te pepa konumohe, e whakamahia ana hei ārai i te māramatanga, te makuku, me te turuturu hau; ko te paparanga o roto he mea hanga ki te kiriata polyolefin (pēnei ikiriata polypropylene), e whakamahia ana mō te hiri wera me te pā ki te kai.
Ka whakamahia ngā pēke korohū hei takai i ngā kai, nō reira he nui ngā whakaritenga haumaru me te kore-hua mō ngā pēke kirihou i roto i te tukanga whakaputa, ā, kāore e taea te poke i ngā momo huakita. Heoi, he mea e kore e taea te karo i roto i te tukanga whakaputa, nō reira he mea tino nui te kore-hua o ngā pēke korohū.Te whakahoromata i ngā putea korohūka taea te wehewehe ki ngā wāhanga matua e toru,
E toru ngā tikanga whakahoromata mō ngā putea tunu kai, arā, te whakahoromata whānui, te whakahoromata pāmahana teitei, me te whakahoromata ātete pāmahana teitei.
Te whakahoromata whānui, te pāmahana korohū i waenga i te 100-200 ℃, te whakahoromata mō te 30 meneti;
Ko te momo tuatahi: momo pāmahana teitei, te pāmahana korohū i te 121 nekehanga Celsius, te whakahoromata mō te 45 meneti;
Ko te momo tuarua: he ātete ki te pāmahana teitei, me te pāmahana tunu o te 135 nekehanga Celsius me te wā whakahoromata o te tekau mā rima meneti. He pai mō te hōtiti, te pūtini raihi Hainamana tuku iho me ētahi atu kai. Ko te momo tuatoru: Ko ngā āhuatanga o ngā putea korohū ko te ātete ki te makuku, te ārai mārama, te ātete ki te pāmahana, me te tiaki kakara, ā, he pai mō te whakamahi i roto i ngā kai kua tunua pērā i te mīti, te hāmi, me ētahi atu.
Ngā pēke wai kohuahe momo pēke kirihou anō nōngā putea korehau, he mea hanga te nuinga mai i ngā rauemi PA+PET+PE, PET+PA+AL rānei. Ko te āhuatanga o ngā putea wai kohua ko te maimoatanga ārai-huaketo i te pāmahana kāore e neke ake i te 110 ℃, he pai te ātete ki te hinu, he kaha te hiri wera, ā, he kaha te ātete pānga.
Ko ngā putea wai kohua ka whakahoromatatia ki te wai, ā, e rua ngā huarahi hei whakahoromata i a rātou,
Ko te tikanga tuatahi ko te whakahoromata i te pāmahana iti, e roa ana mō te hawhe haora i te pāmahana 100 ℃.
Tikanga tuarua: Te whakahoromata pahi, te whakahoromata tonu mō te hawhe haora i te pāmahana o te 85 ℃
Ki te kī ngāwari, ko te tikanga whakahoromata o ngā pēke wai kohua ko te whakamahi i te ātete wera o ngā huakita, ka rongoā i a rātou ki te pāmahana e tika ana, ki te wā whakamahana rānei kia mate rawa ai rātou.
Mai i ngā tikanga whakahoromata i runga ake nei, ka kitea tonu he rerekētanga nui i waenga i ngā putea kohua me ngā putea korohū. Ko te rerekētanga tino kitea ko te pāmahana whakahoromata o ngā putea korohū he teitei ake i te pāmahana o ngā putea kohua.
