Ko te kiriata totoro, e mōhiotia ana ko te kiriata totoro me te kiriata whakaiti wera, i hangaia tuatahitia i Haina mā te whakamahi i te PVC hei rauemi turanga me te DOA hei matū whakapūmau me te pānga piri-ake o te kiriata totoro PVC. Nā ngā raruraru taiao, te utu nui (e pā ana ki te PE, te iti o te wāhi takai mō ia waeine) me te ngoikore o te totoro, i whakamutua te kiriata totoro PE i te tīmatanga o te hanga ā-rohe i te tau 1994-1995. Ko te rauemi turanga ko te LLDPE, tae atu ki te C4, C6, C8 me te metallocene PE (MPE).
Ngā Āhuatanga
Ka hangaia mā te whakamahi i te kapia LLDPE kawemai me te tāpiringa motuhake o te tākai, ā, ka taea te whakaputa kiriata takai maha-mahi mō te mīhini ā-ringa, te mīhini ātete, te mīhini totoro-mua, te ārai-UV, te ārai-pūmau me te ārai-waikura. E whai ake nei ngā painga:
1. Mā te whakamahi i ngā taputapu tākai-rua-paparanga, ka taea e te kiriata takai pēhi te whakanui ake i ngā āhuatanga o ia pūmua katoa, tōna māramatanga, tōna kaha kume, me te ātete ki te poka, kia eke ai ki te āhua tino pai i te pūwāhi rewa.
2. He pai ōna āhuatanga kume, he mārama, he ōrite te matotoru.
3. He roa te whakaroa, he pakari pai, he ātete pai ki te haehae whakapae, ā, he pai rawa te takai piri-ā-roto.
4. He rauemi hangarua e pai ana mō te taiao, kāore he reka, kāore he paitini, ka taea te takai tika i te kai.
5. Ka taea te hanga hua piripiri taha-kotahi, te whakaiti i te haruru i puta i te tukanga takai me te totoro, te whakaiti i te puehu me te onepu i te tukanga kawe me te rokiroki.
Tono
1. Tākai hiri
He rite tēnei momo takai ki te takai kiriata whakaitiiti, ka takaihia te kiriata ki te papa hei takai katoa, kātahi ka hiritia te kiriata i ngā pito e rua e ngā mea pupuri wera e rua. Koinei te momo kiriata takai-a tawhio tuatahi e whakamahia ana, ā, kua arahi ki te whanaketanga o ngā momo takai maha atu.
2. Tākai whānui katoa
Ko tēnei momo takai me whānui te kiriata hei taupoki i te papa, he āhua rite tonu, nō reira he pai mō te whakamahi me te matotoru o te kiriata mai i te 17 ki te 35μm.
3. Tākai ā-ringa
Ko tēnei momo takai te momo takai kiriata māmā rawa atu, ka whakairihia te kiriata ki runga i te whata, mā te ringaringa rānei, mā te hurihuri papa, te kiriata rānei huri noa i te papa. Ko te nuinga o te wā ka whakamahia mō te tākai anō i ngā papa kua takaihia i muri i te pakaru, me ngā takai papa noa. He puhoi tēnei momo takai, ā, ko te matotoru o te kiriata e tika ana ko te 15 ki te 20 μm.
