Kei a koe te mōhio i ngā pūtaiwhenua HDPE me LDPE? Ko ēnei ngā rerenga rima o ngā pūtaiwhenua e whai wāhi ana i tēnā me tēnā wāhi, me tēnā huarahi anō. I tēnei tuhinga ka haere tonu mātou ki te whakamārama i ngā take e mahi ai i ngā pūtaiwhenua HDPE me LDPE hei noa i te āheinga o ēnei, ko tēhea te āhua o te tataki i waenganui i a rātou. Ka whakarite au i ngā pai o ēnei pūtaiwhenua, me pēhea te whakahoki i te tika, me pēhea te whiu ki te taiao (nā te hanga, nā te whakaputu) e āheinga ana ki te taiao, me ngā whakamahi hou e whakamahia ana i a rātou i tenei rā. Tīmata ake tātou ki te ako i te mōhiohia atu!
Ko te take matua e tāpiri ana i ngā pūtaiwhenua HDPE me LDPE he pēhea te rorohiko. Ko HDPE te ingoa poto mo te polietilini rorohiko nui, ko LDPE te ingoa poto mo te polietilini rorohiko iti. Nā te mea he whakatika rawa ake ngā pūtaiwhenua HDPE i ngā pūtaiwhenua LDPE, ko ia te pai rawa hei hanga i ngā mea e hiahiatia ana kia manawa nui, kia roa te ora. Ki tēnā wā, kei reira i ngā mea wharewhare kore huringa ki te hau, ngā paipī me ngā kōpū.
E hia nei ngā take mohio rawa atu hei whakamahi i ngā pūoro HDPE me ngā pūoro LDPE i roto i te mahi whakamahinga. Ā, he nui ngā whiwhinga pai o tēnā mahi, nō te mea he mōkori ngā pūoro e neke ana i aua. Ko tēnā ka taea e rātau kia hanga ko ngā momo rangahau tuatahi ki runga i ngā hua noa i te ao. Nā tō rātau mōkori, ka taea e ngā kaihanga kia hanga ngā mea noa, mai i ngā pātiti ki ngā wāhi whakapakari, Tāne.
He whakatūroro nui kia whakahokia ngā pūoro HDPE me ngā pūoro LDPE hei tiaki i tō tātou taiao. E ahu ana ngā momo pūoro nei ki te wā e hirango ana - i ētahi wā, e raro i te rau tau - kia puta iho ki te whenua i roto i ngā paheko whenua. Ki te kore rātau e haere ana i roto i ngā paheko whenua mo te wā e hirango ana, ka kitea he mate nui i te taiao. Ka taea e te whakahoki i ēnei momo pūoro e whakaiti haere ana i te nui o ngā mea taketake e tae ana ki ngā paheko whenua.
Ko te aha nei te hāpai i ngā rorohiko HDPE me ngā LDPE? No hea, tuatahitia tātahi ki ngā momo rorohiko e rerekē ana, ā, homai hei whakatika i ngā kai rite, ngā pūhoro rite hoki i roto i a rātou. Ka taea e rātou te tīmata i te whakarere, ka whakapakari, ka uhi anō ki te hanga o ngā mea hou. Ko te HDPE i whakahoutia, ināianei ka whakamahia hei rākau rorohiko mō ngā pūrere me ngā tawāhi pātaka, nō reira ka hanga i ngā kete hou rānei ko ngā LDPE hei whakamarumaru rite. Ko te whakahoutia he whakangungu i ngā taonga, i te waiora, ā, ka heke i te upoko hua, no reira he nui te hē ki te whai take pai!
Ko te HDPE me te LDPE e ngā pai tūmomo katoa nei, engari me mohio hoki tātou i te whiwhi o ā rātau hanganga me te whakatupu i ngā pūnana i te taiao. Kua kitea he nui ngā waihape kua whakamahia mo te hanga i ēnei pūnana, ko te mahi anō ka puta mai iho he hauhau āhuarangi e uiui ana i te huringa āhuarangi. Ko te atehau anō, ki te kore ēnei pūnana i whakahokia ki te wāhi whakawhiti rēpeka, ka tae noa ki te kawe rēpeka ki ō tātou reira, papatūānuku, me ngā moana. Ka mate ai te taiao me te whakarerekē i ngā whenua tūturu.
Ā, ko te LDPE pūnana ka kitea i waenganui i ngā tūranga hou whai take, hei tauira, i ngā paerae kiko whatitiri. Ko te roa o te whakapono me te tonu o ēnei paerae kiko whatitiri ka taka tonu ki te whakangungu i te waihotanga o te wai-āhua, i runga i ngā paerae kiko whatitiri o era atu. Nō te taimatatanga nei, ka whakamahi ngā pūnana HDPE me LDPE hei hanga i ngā rara hou mō te tuhinga 3D. Ka whakarerekētia te hanga me te whakawhanake i te hunga whakairo mō te hanga.
