Hītori whanaketanga pepa kapu PE

He mea hanga te pepa kapu PE hei whakakapi i ngā kapu kirihou tuku iho, he mea auaha, he mea atawhai hoki ki te taiao. He momo pepa motuhake kua pania ki te paparanga angiangi o te polyethylene, kia ātete ai te wai, kia pai ai hoki hei kapu whakakorekore. He haerenga roa, he haerenga whakamīharo hoki te whanaketanga o te pepa kapu PE, he maha ngā wero me ngā putanga hou i te ara.

Ko te hītori o te pepa kapu PE ka taea te whai i ngā tau tōmua o te rautau 1900, i te wā i whakaurua tuatahitia ai ngā kapu pepa hei whakakapi mō te hauora me te watea i ngā kapu uku, karāhe rānei. Heoi, kāore i tino pakari ēnei kapu pepa o mua, ā, he āhua turuturu, he hinga rānei ina whakakīia ki ngā wai wera. Nā tēnei i hua ake ai te whanaketanga o ngā kapu pepa pania ki te ware pi i ngā tau 1930, he ātete ake ki ngā wai me te wera.

I ngā tau 1950, i whakaurua tuatahitia te polyethylene hei rauemi paninga mō ngā kapu pepa. Nā tēnei i taea ai te hanga kapu he ātete wai, he ātete wera, he pai ake hoki mō te taiao i ngā kapu pania ki te ware pi. Heoi, tae noa ki ngā tau 1980 ka tino whanakehia te hangarau me ngā tukanga hanga e tika ana mō te hanga pepa kapu PE i runga i te tauine nui.

Ko tētahi o ngā wero matua i roto i te whakawhanake i te pepa kapu PE ko te kimi i te taurite tika i waenga i te kaha me te ngāwari. Me kaha te pepa kia mau ai ngā wai me te kore e turuturu, e hinga rānei, engari me ngāwari hoki kia hangaia hei kapu me te kore e haehae. Ko tētahi atu wero ko te kimi i ngā rauemi mata e hiahiatia ana hei hanga pepa kapu PE i roto i ngā rahinga nui. I hiahiatia tēnei kia mahi tahi ngā mira pepa, ngā kaihanga kirihou, me ngā kaihanga kapu.

Ahakoa ēnei wero, kei te piki haere tonu te hiahia mō ngā momo kapu kirihou tuku iho e pai ana ki te taiao, e pumau ana hoki. Inaianei, e whakamahia whānuitia ana te pepa kapu PE i roto i ngā toa kawhe, i ngā mekameka kai tere, me ētahi atu ahumahi ratonga kai hei kōwhiringa pai ake mō te taiao. Kei te piki haere hoki te rongonui o tēnei mea i waenga i ngā kaihoko e āwangawanga ana mō te pānga o ngā para kirihou ki te taiao.

Hei whakamutunga, he haerenga roa, he haerenga whakamīharo hoki te whanaketanga o te pepa kapu PE, ā, he maha ngā tau i hiahiatia ai te rangahau me te whanaketanga. Heoi, ko te mutunga iho he hua e pai ana ki te taiao, ā, e whai hua ana hoki ki te taha ōhanga. I te mea kei te piki haere tonu te hiahia o ngā kaihoko mō ngā hua e pai ana ki te taiao, tera pea ka kite tātou i ētahi atu whanaketanga i roto i te whanaketanga me te whakaputa i ngā hua matomato pēnei i te pepa kapu PE.
