HDPE = High-Density Polyethylene Ko tēnei he mīhini whakairo i te pūoro e mohio ana hei whakapuhi me te whai wā. Ka taea e ia te whai mō ētahi tekau tau ki muri i te korenga. Te nui o te pai o te HDPE, ko tana whiu ki ngā momo rongoā. E kore e riro i te mōhio mai i ngā hua pūtakea pūngao. No reira, ko te HDPE ka whiu ki ngā ira o te rā (nō te UV), me utu pai he whakaaetanga mō ngā mahi e whai wā tonu ana i waho. Nā tēnei, ka whakamahia te HDPE i ngā mahi pūnaha wai, ngā kāpiti, ā, ko ngā mahi kāreti me ngā nohonga waho hoki.
Ko te LDPE he pioi iti noa iho mo te Polyethylene o te Rawaheiti Iti. He mea tino rerekē tēnei kākano i roto i te HDPE, nō reira, he mēhā te mea nei i te māku, i te āwhiwhatu, me te whakaputu. Ko te nui ake te waweanga, ko te nui ake hoki tōna e āhei ai ki te hanga i waehanga katoa, nā tēnā anō ka pai te LDPE mo te hanga o ngā mahi pērā i ngā kete kākano, ngā whakaputuputu kai me ngā rawa whakarite katoa. Ka noho māmā ake hoki te LDPE i runga i te whakatū i tētahi atu, ahakoa iti rawa te utu, nā tēnā anō ka whakamahia mai ki ngā mea o te ao kotahi.
I nāianei, tēnā whakamātau atu ki ngā pai me ngā hē o te HDPE & LDPE. He maha ngā pai o te HDPE. Kei te mutunga he nui te mana ākiaki me te whanuitanga. Ko tēnei ka taea e ia te tirohia hei pai mō ngā whakamahi e hiahiatia ana te mana, pērā i te hanga me te whakapono. Tēnei, tae atu ki te whiuwhe o te HDPE ki ngā rūkura ā-wahie me ngā utu UV, ka taea e koe te whakaaro kia kore e hiahia ana koe ki te whakamahia i tēnei waho. Ka kitea i ngā mahi pērā i ngā mea tuhura noa, ngā paoro wai, me ngā kāpiti mō ngā mea hōhā.
I nāianei, tēnā whakamātau atu ki te LDPE. Ko tēnei momo poraka e āhei ana ki te whakarerekē ki runga i ētahi atu heke. Ko tēnei āhuatanga kei te whai hua nui mō te hanga i ngā kete poraka, ngā whakaputuputu kai, me ētahi atu matāpuhi whakapakoko e hiahiatia ana kia haerekeke me te whakawai. Ko te LDPE he iti rawa anō hoki te utu ki te hanga i tēnei i te HDPE me ētahi atu poraka, koia nei ka noho tawhito ake ai tēnei ingoa i roto i ngā mea hou o te ao.
Nō te mea, ko te LDPE he whiwhinga waihanga mō ngā mea hē ki te ao. Ko te polietileni hoki e whakamahi ana hei hanga i ngā kete rama, pērā i ahe kete ka kite ai koe i ngā pūtau kai. Ka whakamahi anō ia hei hanga i te rama whakapiri, he rama e tae ana ki roto i ngā mea ki te tiaki i aua mea. Ka haere te kai i roto i te LDPE kia puawai. Nō reira, ka mohio ia hei wāhanga hei hanga i ngā pūtōki porotiti, i ngā totohu ā-pūnaha, me ngā whiria rama.
Ka hiki noa iho tēnei i aheahe i te mea e whakamahia ana te rama hei aha, ka whakaatuhia he aha nui rawa mo ōu hiahia. Ko te HDPE he tino whanonga pai mō te mea e hiahiatia ana te rite pai o te rama ki ngā momo raruraru me ngā utu UV. He pai tēnei mō ngā mea tuwatawata mahaki me ngā kono e hiahiatia ana kia mau i ngā hua rite nui. Ka tukuna e ia te korekorenga i te whakamahi; engari, kei te whakamahi me te rama nui rawa, me te āhua kaweke, ka pai rawa te LDPE. Ko te LDPE: He pai mō ngā kete me ngā whiwhinga waihanga nui rawa (e painga ana).
Te Pānga mo te Taiao o te Whakato HDPE ki runga i te LDPE Ko ngā pānga katoa o HDPE me LDPE ki te taiao. He mea hokohoko rātou mai i ngā manuka whatu, e hīnā ana tērā i te whakato ka taka ki te huringa āhuarangi. Ko tēnei he mea nui hei whakaaro i te wā e whakamahia ana te poraka. He mea hura noa iho tētahi atu mea pai, ko te whakahoki. Ki te whakahoki ngā poraka nei, ka taea te hanga i ētahi mea hōu, mā reira ka kaua e tuku ki roto i te kaiwhata, kei noho ai rātou i roto i ngā whenua kawe, ki te taiao rānei.
