Ma mua o kakīʻaha pepa makahana ʻia i 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.

PE kīʻaha pepa i uhi ʻia

I mea e paʻa ai 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 uhi PE.ʻO ka uhi PE he meaʻai 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 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, ka palaoa, 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.
