Ngā Rauemi Taura Hiko: He Aratohu Kōwhiri mō te PE Ātete-Mura, te PP Ātete-Wera, me te ABS Ātete-Mura

I roto i te hanga taura hiko, ka pā tika te kōwhiringa rauemi ki te haumaru hiko, te kaha miihini, me te roa o te mahi. Ko te PE, te PP, me te ABS ngā rauemi e toru e whakamahia whānuitia ana. Ko te PE me te PP te nuinga e whakamahia ana mō te whakamahana waea me te hipoki, ko te ABS ia e whakamahia ana mō ngā mono me ngā whare.

I. PE (Polyethylene)
PEHe rauemi whakamahana waea tawhito tēnei, he pai te whakamahana hiko, he ngāwari, he ātete pāmahana iti, ā, he tino iti te mimiti wai. He pai mō te whakamahinga roa mai i te -40°C ki te 80°C, he mea tino pai mō te whakamahana o roto o te taura hiko. Kāore te PE paerewa e ātete mura (taupū hāora 17–18) ā, me whakarerekē te ātete mura (hei tauira, me te konupora hauwai, te konupora hauwai rānei) kia tutuki ai ngā paerewa haumaru. Ka whakamahia te PE mō ngā paparanga whakamahana i roto i ngā taura hiko, ngā waea hiko, me ngā taura raraunga, ā, ka taea hoki te mahi hei uhi taura māmā. Kāore i te nuinga o te wā e whakamahia ana mō ngā whare mono.

II. PP (Poroporoperene)
He pai ake te PP i te PE i roto i te ātete wera me te kaha miihini. Ko ngā momo kua whakarerekētia ka tutuki i ngā pāmahana mahi roa mai i te 100°C ki te 105°C, me te ātete tino pai ki te piko, ki te ngenge, me te pumau matū. He pai te PP mō ngā waea hiko, ngā taura waea, me ngā taura hiko pāmahana-waenga ki te teitei e hiahia ana ki te ātete wera me te roa. Pērā i te PE, ko te PP te nuinga o te wā e whakamahia ana mō ngā tono waea. He iti ake tōna pakari me te kaha pānga i te ABS, ā, ko tōna whakahekenga pokepokea ai te mea kāore e pai mō ngā whare mono.

III. ABS
He kirihou hangarau te ABS mō ngā mono me ngā whare taura hiko. Ka whakakotahi i te pakari, te ātete pānga, te pumau o ngā āhuatanga, me te kanapa o te mata, me te kaha tukatuka whakarewa werohanga pai rawa atu. He mura te ABS paerewa (tata ki te 18 te taupū hāora), nō reira me ātete mura te ABS e tutuki ana i ngā whakatauranga UL 94 V-0, V-2 rānei mō ngā tono taura hiko. Kāore te ABS e pai mō te whakamahana waea, ā, ka whakamahia anake mō ngā wāhanga kirihou o waho.

IV. Ngā Taunakitanga Kōwhiringa
PE: Mō ngā paparanga whakamarumaru i roto i ngā taura hiko, ngā waea hiko, me ngā taura raraunga e hiahia ana ki te mahi whakamarumaru teitei me te ngāwari. Me whakamahi te PE kua whakarerekētia hei ārai i te mura.
PP: Mō ngā waea hiko, ngā taura waea, me ngā taura hiko pāmahana-waenga ki te pāmahana teitei e hiahia ana kia nui ake te ātete wera me te ātete piko.
ABS Ārai-Mumura: Mō ngā mono, ngā whare urutau, ngā topenga taura, me ētahi atu wāhanga hanganga. Tīpakohia te ABS e tutuki ana i ngā whakatauranga ārai-mumura UL 94.
Mā te whiriwhiri tika i ngā rauemi ka tino haumaru, ka roa, ka ātaahua hoki ngā taura hiko.
