Ma mua o kakīʻaha pepa makahana ʻia i mau kīʻaha pepa, e hoʻopili ʻia kahi papa o ka uhi ma ka pepa kumu, i hiki i nā kīʻaha pepa ke paʻa i nā wai a me nā mea inu ʻē aʻe.
Hiki ke hana ʻia nā ʻāpana kīʻaha pepa mai nā ʻano plastik like ʻole, a hiki ke hana ʻia nā kīʻaha pepa me ka uhi ʻole ʻia. No laila he aha ka ʻokoʻa ma waena o nā ʻano uhi like ʻole? I kēia lā wau e hoʻolauna aku iā ʻoe.
I mea e paʻa ai ka wai o nā kīʻaha pepa, e uhi ʻia ka loko o nā kīʻaha pepa me kahi kiʻi ʻoniʻoni. Hoʻopili ʻia nā kīʻaha pepa i uhi ʻia me ka PE. ʻO ka uhi PE he mea hoʻopili meaʻai hiki ke pili me ka meaʻai. ʻAʻole waihoʻoluʻu, ʻaʻala, ʻaʻohe mea ʻona, hana ʻia me ka naphtha, a ʻaʻole hiki ke hoʻohaʻahaʻa maoli ʻia.
Welina mai iā ʻoe e kiʻi i ka laʻana e pili ana i ka pepa i uhi ʻia
PLA pepa kīʻaha - bioplastic
Nā kīʻaha pepa PLA, e like me nā mea ʻē aʻekīʻaha pepa, loaʻa i kahi ʻāpana lahilahi o ka uhi ʻili i loko, akā hoʻohālikelike ʻia me nā kīʻaha pepa i uhi ʻole ʻia i ka palaki ʻole, PLA i hana ʻia i nā mea kanu e like me ke kō, cornstarch, ke kō a i ʻole nā beets kō, He bioplastic biodegradable.
He wahi heheʻe haʻahaʻa ko PLA, no laila ʻoi aku ka maikaʻi no nā mea inu anuanu ʻaʻole i ʻoi aku ka wela ma mua o 40 degere celsius. Ma kahi e pono ai ke pale ʻana i ka wela, e like me ka ʻoki ʻoki, a i ʻole nā poʻi no ke kofe. Hoʻopili kēia i ka hoʻohui ʻana i ka paʻakai i ka PLA e hana ma ke ʻano he catalyst, a laila hoʻomaʻamaʻa wikiwiki a hoʻoluʻu i ka resin PLA i ka wā hana.
Lawe nā huahana PLA i 3-6 mau mahina e hoʻopuehu ʻia i loko o kahi ʻōnaehana hoʻoheheʻe ʻenehana. Ke hoʻohana nei ka hana ʻana o PLA i ka 68% ka liʻiliʻi o nā kumu waiwai mōʻalihaku ma mua o nā plastik maʻamau a ʻo ia ka polymer kinoea hoʻomaʻemaʻe mua o ka honua.
E wehewehe ʻia ka ʻike e pili ana i nā kīʻaha pepa.Inā makemake ʻoe e ʻike hou aku e pili ana i nā kīʻaha pepa, ʻoluʻolu ʻoe e kaomi ma aneʻi e lawe mai iā ʻoe i nā ʻatikala maikaʻi aʻe.
