Ko te ingoa 'pūtau LDPE' he mea e mōhio nei koe i mua atu, engari e mōhio ana koe i te mea he aha rātou, ā, he aha ō rātou whakamahi? Ko te polyethylene iti-peketo (LDPE) he momo rorohiko hereketanga e whai wāhi ana i te maha o ngā whakamahi. Ko tēnei tuhinga ka tirohia ngā pūtau LDPE, ō rātou whakamahi i te oranga kotahi, me te take ihea he pai rātou mō ngā pakihi e arohatia ana te taiao.
Nā runga i te pūtaiao e whai ake nei i te roroa, he iti noa ngā kōhiti porotēnika hakahaka, he hanganga iti o te miro e kitea ai i te pūmotu, ka tae mai i te roroa. Ko tēnei miro he mea e mōhiotia ana hei 'terima', e hīnati ana he take tonu ki te whakatika anō me te whakaputu anō i waenga i ngā wā, kāore i te whakarereke. He horoi āmio ngā kōhiti LDPE, ko te ara pai ki te tuku atu, ko te pai rawa hoki te taurite. Ka taea te whanake i te wai (he mea kauwaha i te wai), i ngā miro me te rāwhiti hoki. He wawe noa te mahi i roto i ngā hanga mea, nā te mea ka whakamahana i te wā e hīnati ana.
Tahuri atu te whakarongo ki ētahi tono matua mō ngā tūtohu LDPE, me tērā pea tēnā me whakamātau i a rātou tuatahitia. Hei dāta, ka kitea i roto i ngā rara o te pākiri. Pēnei i ēnā kete pākiri plastikihana e tango nei i a tātou i te paku, ngā whakaputuputu e tiaki ana i te kai kia ora, rānei ko ngā whakaputuputu pūoro e tiaki ana i ngā taonga wāhanga i te wa o te hokohoko. No reira i runga i te pākiri, ka hanga hoki ngā tūtohu LDPE hei whakangungu i ngā mea hākinakina. E āhei ana rātou ki te whakawehenga i ngā wāhi wai e hau ana i a tātou, ki ngā tākaro tino ngenenge e whakamahi nei, me ngā rautaki kaiwhakaawe i te kai e whakamahi nei ki te mea kai. Ka whakamahi anō he mahi ā-waea me ngā mahi hanga ki ngā tūtohu LDPE, nā te mea he pai rawa ōna āhuatanga tiaki i te uruora. Ka taea e rātou te whakatuwhera i ngā herenga, te tiaki i ngā kāpori, me te hanga i ngā paetaha e tiaki ana i te wai hei kore i ngā whare.
Ka tū mātou ki te kōrero mo te hanga i ngā mea plastik, he raro nui ngā take e hiahiatia ana e te LDPE granules hei whai. Tuatahitanga, he iti noa rātou, e hīnātia ana, arā, kaore he nui ngā moni hei hoko. Tuatoru, ko te wāhanga mahi nei, nui rawa atu te wāhanga mahi, ā, mēnā ka whakaae ngā kaihangarua ki te hanga i ngā mea e hiahia ana ia ki te hanga. Ko te whakapakari ake hoki o ngā LDPE granules i te whanuitanga me te pūmau ki te mea tuatahi, e hīnātia ana te rangitahi, e roa tonu ana te wā. Ka taea hoki e te LDPE te whakahaere i ngā momo thermoplastic kē hei whakapakari ake i ana āhuatanga. He whakaorangorongo hoki ngā LDPE granules, ko tēnā tētahi o ōna mea pai rawa. Arā, ka taea te whakahokia i aua mea hei hanga i mea hou, e painga ana i te kotahitanga mō ngā pakihi e hiahia ana ki te tiakina i te waipiro me te whakawhanake i te taiao.
E ai he waahanga matua ka whai ake i te kōwhiringa LDPE granules ki te hoko. Ko tētahi o ngā āhuatanga nui rawa ko te pai o te rauropi. Ko te rangi i tuhi nei he tohu mō te pai me te horoi o ngā granules LDPE. Ka āhei ngā rangi i waenganui i ngā pūkengi, nā reira, he nui te hērautanga kia tiimata koe i te whakamana i te rangi e hiahiatia nei hei whakamahi mo tō hiahia.
Nga Rangahau mō te Whakaputa i ngā Granules LDPE Ko ētahi atu rangahau mō te whakaputa i ngā granules LDPE. Ko ētahi atu o ngā momo hangarau e whai ana ko te whakapiki, te whakawhiti koropupū, me te whakapuaki hangarau. Kei te whai take te hunga whakamahi i te mahi i te mea e hiahiatia ana, me ngā āhuatanga e hiahiatia ana. Nā te mea, ko te whakapiki te mea e mahi ai i ngā whakapakanga, ko te whakapuaki hangarau he hunga whakamahi hei hanga tamariki, kete, rānei ko ētahi atu mea whare.
He tino whakaaetanga ngā pūtau LDPE (Low-Density Polyethylene) mō ngā pakihi e hiahia ana ki te whiwhi i te manaakitanga moana. E hīnā ana he mea kei te kore e noho ana i ngā wāhi tāhū, nā reira ka whai pānga te whiwhi. Ko te hanga pūtau LDPE he iti rawa i te waihotanga i ētahi atu rorohiko. Ko tēnei e whakanui ana i te whakaiti i ngā uku me ngā hā o ngā piripiri, pai tonu mō ā tātou rangi. Ka taea e ngā pakihi te hanga i ngā mahi whakapono, whai wātea, me ngā mea e taea te whakahokia, ko ngā pūtau LDPE - ka taea e rātou te hanga i tētahi ao e pai ake.
