RPET, hoʻohana mau ʻia ka pōkole o ka polyethylene tetraphyte recycled.E wehewehe mākou iā PET ma lalo nei.Akā i kēia manawa, e ʻike ʻoe ʻo PET ka hā o ka resin plastic i hoʻohana nui ʻia ma ka honua.Hiki ke loaʻa ka PET i nā mea a pau mai ka lole a me ka ʻeke meaʻai.Inā ʻike ʻoe i ka huaʻōlelo "RPET", ʻo ia hoʻi ʻo ka PET i hoʻohana ʻia i ka huahana e hele mai mai kahi kumu i hoʻohana mua ʻia.
He aha ka polyethylene Tetraphyte?
No ka maopopo ʻana, ua hana ʻia kēlā me kēia plastik āu i hoʻohana ai me ka polymer.E hana ʻia nā hue waiu PVC me kahi mea ʻokoʻa ma mua o nā hue wai PET.
Hana ʻia ka PET mai ka ʻaila ʻaila.Hoʻopilikia nui ʻia ke kaiapuni e ke kaʻina o ka ʻili ʻana i ka ʻaila mai ka lepo.No ka hana ʻana i ka PET i hoʻoheheʻe ʻia, pono ʻoe e lawe i ka waiʻona i kapa ʻia ʻo Ethylene glycol a hui pū me nā waikawa terephthalic.Hana ʻia ka Esterification ke hoʻopaʻa ʻia nā huahana ʻelua, e hana ana i ka PET, kahi polymer kaulahao lōʻihi.
Koho mākou i nā polymers e pili ana i ka hana ʻana o ka huahana hope.He thermoplastic ka PET.ʻO ia hoʻi, hiki iā ia ke hoʻokuʻu maʻalahi i ke ʻano i makemake ʻia ma ka hoʻomehana ʻana iā ia, a laila e paʻa i kona ikaika ke maʻalili.ʻO ka PET he māmā-kaumaha, nontoxic a lōʻihi loa.ʻO ia ke kumu i makemake nui ʻia ai nā mea hoʻopihapiha no ka ʻoihana meaʻai a me nā mea inu.
Hoʻohana wale ʻia nā PETs no ka hoʻopili ʻana?
ʻAʻole. ʻO kaʻoihana'ōmole'ilika ka mea hoʻohana nui loa o PET ma ka honua ma 30%.Eia naʻe, ʻaʻole kēia wale nō ka hihia.ʻOiai ua kapa ʻia ʻo PET ma ke ʻano he polyester, he nui paha nā lole i loko o kou ʻaʻahu i hana ʻia mai PET.ʻAʻole ʻae ʻia ka wai e hoʻoheheʻe i ka ipu i hana ʻia.Akā, hele ia ma ka spinnerate (kokoke i ke poʻo ʻauʻau) a hana i nā kaula lōʻihi.Hiki ke ulana pū ʻia kēia mau kaula e hana i ka lole māmā a paʻa.ʻO ka polyester ka fiber i hana ʻia e ke kanaka ma ka ʻoihana textile.ʻOi aku ka maʻalahi o ka polyester ma mua o ka pulupulu, a ʻoi aku ka liʻiliʻi o ke kumukūʻai ma muli o ke ʻano o ka wā.Loa'a paha ka polyester i kou lole e komo nei i kēia manawa.Hoʻohana nui ʻia ka polyester i ka hana ʻana i nā hale lole a me nā kāʻei conveyor.Hiki i ka Polyester ke lawelawe i nā mea āpau e pono ai ka māmā a me ka lōʻihi.
ʻO nā helu maikaʻi a maikaʻi ʻole o PET
He nui nā pōmaikaʻi o ka PET, ʻo ia hoʻi ka lōʻihi a me ka maʻalahi a ʻoi aku ka maikaʻi ma mua o nā koho ʻē aʻe.Hiki ke hana hou ʻia ka PET, e like me nā plastics ʻē aʻe.Ma UK, 3% wale nō i hana hou ʻia mai nā ʻōmole PET i ka makahiki 2001. Ua piʻi kēlā helu i 60% i ka makahiki 2014 ma muli o ka hoʻololi ʻana o nā mea hana inu i nā ʻōmole PET i nā wahi a pau e hiki ai, a ʻoi aku ka nui o nā hana hoʻomaʻamaʻa ʻāina e maʻalahi ai ka hana hou ʻana.
ʻO ka PET kekahi o kāna mau nāwaliwali nui loa.He pūhui ikaika ʻo PET a hiki i 700 mau makahiki ke hoʻohaʻahaʻa i ka lepo.ʻOiai ua ʻike ka hana hou ʻana o PET i nā hoʻomaikaʻi nui i nā makahiki he ʻumi i hala iho nei, pono e hana hou ʻia.Nui nā wahi o ka honua i nā mauna e like me nā kūlanakauhale liʻiliʻi, i hoʻopiha ʻia me ka plastik PET wale nō.Ke hoʻomau nei mākou i ka hoʻohui ʻana i kēia mau ʻāina i kēlā me kēia lā ma muli o kā mākou hoʻohana nui ʻana i ka PET.
ʻO ka plastik PET kahi hui lōʻihi loa.He 700 mau makahiki no ka wāwahi ʻia ʻana o ka plastik PET inā pau ia i loko o ka ʻāina.Aia kekahi mau ʻāpana o ka honua he mau mauna ka nui e like me nā kūlanakauhale liʻiliʻi, akā hana ʻia lākou a pau me ka plastik PET.
No laila, pehea e hiki aiRPEThoʻoponopono i ka pilikia haumia plastik i ko kākou honua?
Lawe ʻo RPET i ka plastik i hana mua ʻia (maʻamau i nā ʻōmole plastik) a wāwahi iā ia i loko o nā ʻāpana liʻiliʻi.Hoʻokaʻawale ʻia ka PET ma ke kumu o kēlā me kēia ʻōmole ma ka hoʻoheheʻe ʻana i kēia mau flakes.Hiki ke hoʻohana ʻia ka PET no ka hana ʻana i nā mea āpau mai nā sweaters a i nā ʻōmole plastik ʻē aʻe.ʻO kēia PET he 50% ʻoi aku ka maikaʻi o ka ikehu ma mua o ka hana ʻana i ka PET mai ka ʻōpala.Eia hou, hiki ke hoʻohana ʻia nā ʻōmole i loaʻa e hana i ka PET, ʻo ia hoʻi, ʻaʻole lākou e pau i ka pae ʻāina.ʻAe kēia iā mākou e haʻalele i ka honua e like me ia.Ma mua o ka unuhi ʻana i ka ʻaila koʻikoʻi, hiki ke hoʻopōʻino loa, hoʻohana mākou i ka nui o ka huahana i hiki ke kōkua pololei i ka pae ʻāina.
