Me mōhio te katoa ki te pepa. Nā te mea ka taea e tātou te kite i ngā momo hua pepa katoa i roto i ngā āhuatanga maha o te oranga o ia rā. Hei tauira, e mōhio ana tātou ki ngā kapu pepa, ngā peihana pepa, ngā pereti pepa me ngā pouaka kai tere. E mōhio ana tātou katoa he hihiko te pepa (he ngāwari ki te mimiti i te makuku) ā, he iti te kaha pakū. Engari ki te tupato koe, ka kitea e koe he kiriata pā mārama, kanapa, maeneene kei roto i ēnei pepa. He kiriata PE tēnā, e ahua nei ka pania te pepa ki tētahi paninga makutu, ka hoatu ki a ia te mana nui o te kore wehi i te wai me te hinu. Kia hurahia ngātahitia te mea ngaro o te pepa pania!

He aha te PE?
I mua i te mārama ki te pepa pania PE, me kōrero tātou mō tōna rauemi matua - te polyethylene. Ko te Polyethylene te whakarāpopototanga mō te PE, he kapia kirihou wera i whakapūmautia mai i te ethylene. Ko te āhua o te polyethylene he matūriki ware pi ma, he kore reka, he kore kakara, he kore paitini, ā, he rite ki te ware pi. Ko te āhuatanga matua o te polyethylene he iti te utu, he ātete pai ki te makariri, he pumau matū, he whakamarumaru hiko me ētahi atu āhuatanga. Nō reira, he whānui rawa ngā whakamahinga. Ko te nuinga e whakamahia ana i roto i te hanga kiriata, rauemi takai, ipu, paipa, waea me ngā taura, ngā mea e hiahiatia ana i ia rā, me ētahi atu. Heoi anō, ka taea te whakamahi hei rauemi whakamarumaru auau-teitei mō ngā pouaka whakaata, ngā radar, me ētahi atu. Mai i tōna whakamahinga i te tau 1922, kua whanake te polyethylene hei kapia hangai nui rawa atu o te ao me te kai nui rawa atu o ngā rauemi takai kirihou. He tūranga nui tōna i roto i te umanga kirihou.
Te Whakarōpūtanga o te PE
Nā te rerekētanga o ngā tukanga whakapūhui o te polyethylene, he rerekē anō hoki tōna hanganga, ā, he tino rerekē anō hoki ngā āhuatanga o te hua e rite ana. Ka taea te wehewehe i te nuinga ki: Polyethylene Matotoru-Iti (LDPE), Polyethylene Matotoru-Rārangi (LLDPE), Polyethylene Matotoru-Tiketike (HDPE).
LDPE: E whakamahia ana mō te pepa hangai, te kiriata ahuwhenua, te kiriata mō ngā takai ahumahi, te waea, me ētahi atu;
LLDPE: E whakamahia ana mō ngā waea me ngā taura, ngā paipa, ngā mea e hiahiatia ana i ia rā, me ētahi atu;
HDPE: E whakamahia ana mō ngā here, ngā taura, ngā kupenga hī ika, me ētahi atu.
Te tohatoha o te kaha whakaputa PE mā te whenua
I te marama o Āperira 2022, kua eke te kaha whakaputa PE o Haina ki te 29.18 miriona tana, e 21% o te kaha whakaputa PE katoa o te ao. E kitea ana i roto i ngā raraunga ko te kaha whakaputa PE o te ao kei Haina, te Hononga o Amerika me Saudi Arabia te nuinga. I tēnei wā, ko Haina te whenua me te kaha whakaputa polyethylene nui rawa atu o te ao.
He aha te pepa pania PE?
Kua mārama kē tātou ki te PE i runga ake nei, nō reira, he aha te pepa pania PE? He māmā noa iho, ko te pepa pania PE he rauemi hiato i hangaia ki te pepa hei rauemi turanga, ā, he paparanga kiriata polyethylene kei runga i te pepa turanga, arā, ka pania ngā matūriki kirihou ki runga i te mata o te pepa e te mīhini whakarewa. He ngāwari te mākū o te pepa, engari i muri i te whakakotahitanga pai ki te polyethylene, ka taea e te pepa pania te whakatutuki i ngā pānga o te ātete ā-wai, te ātete hinu me te ātete pāmahana teitei.
Te whakarōpūtanga o te pepa paninga PE
E ai ki te rerekētanga i waenga i te maha o ngā kiriata pania, ka taea te wehewehe ki te pepa pania PE kotahi-taha, te pepa pania PE rua-taha, me te pepa pania PE ā-paparanga.
1. Pepa PE pania taha-kotahi
Ko te pepa PE-panihia taha-kotahi ka pania ki te kiriata PE i te taha kotahi o te pepa turanga. Ka whakamahia ki roto i ngā kapu pepa inu wera, pepa hāmipeka, me ētahi atu.
2. Pepa PE pania taha-rua
Ko te pepa PE takirua-taha he pepa PE paninga i ngā taha e rua o te pepa turanga. Ka whakamahia i roto i ngā kapu pepa inu matao.
Pepa pania ā-paparanga
Ko te pepa paninga hanawiti he paninga PE i waenganui i ngā pepa turanga e rua hei hanga i tētahi wahi pepa hei whakarei ake i te ngāwari o te pepa.
He mea whakamahi noa i roto i: ngā takai whakamaroke, ngā putea takai kai, me ētahi atu.
E ai ki ngā momo paninga, ka taea te wehewehe kia rua ngā momo: te kiriata kanapa me te kiriata-iti.
Ko te kiriata kanapa he kiriata polyethylene taha-rua mārama, he mata kanapa, he ringaringa maeneene. Ko te kiriata matte he kiriata polyethylene matte, he kiriata matte, he mata kohu.
He māramatanga teitei ngā tae o ngā kōwhai, ā, he kanapa ake ngā tae o te mea tā. He mātotoru ake ngā tae o ngā kiriata matte.
Te whakamahinga o te pepa pania
He hononga tata te pepa paninga ki tō tātou oranga o ia rā, ā, he whānuitia ōna whakamahinga, ko te nuinga e whakamahia ana mō te takai, te kai, te hauora, te hikohiko, te taputapu, te tapahi mate, me ētahi atu.
Te whānuitanga o te tono o te pepa pania:
Te whānuitanga o te whakamahinga o te pepa pania
1. Ngā matū: ngā takai whakamaroke, ngā pōro namu, te paura horoi, ngā mea tiaki.
