ʻO ka ʻenehana hana o nā kīʻaha wai plastik ka mea maʻamau i ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana. Ua kapa ʻia ke kaʻina hana puhi ʻo ka ʻōmole puhi. No ka mea he nui nā mea plastik no ka hana ʻananā kīʻaha wai, aia nā AS, PS, PP, PC, ABS, PPSU, TRITAN, etc. I ka hoʻomaluʻana i nā kumukūʻai, nui nā mea hana a me nā mea kūʻai kīʻaha wai e noʻonoʻo e pili ana inā hiki iā lākou ke hoʻohana i ka mold hoʻokahi no ka hanaʻana i nā mea plastic a pau. Hiki paha kēia? Inā hiki ke hoʻokō, e like anei ka hopena o ka huahana i hoʻopau ʻia?
No laila e kamaʻilio kaʻawale kāua. I ke kaʻina hana hoʻoheheʻe ʻia, ʻo nā mea maʻamau i hoʻohana ʻia ʻo AS, ABS, PP, a me TRITAN. Wahi a nā hiʻohiʻona o ka mea a me nā hoʻololi i hana ʻia i ka wā o ka hana ʻana, hiki ke hoʻokaʻawale ʻia ʻo AS a me ABS i ka mold hoʻokahi, akā ʻaʻole hiki i ka PP a me ka TRITAN ke kaʻana like i ka hoʻoheheʻe ʻana i ka wā o ka injection. I ka manawa like, hiki ke kaʻana like i ka mold me AS a me ABS. ʻOkoʻa ka nui o ka emi ʻana o kēia mau mea, ʻoi aku ka nui o ka emi ʻana o nā mea PP. Hoʻohui pū ʻia me ke ʻano hana o ke kaʻina hana hoʻoheheʻe injection, ʻaʻole kaʻana like nā mea plastik i nā ʻōpala.
Ma ke kaʻina puhi ʻana o ka hue, hiki i ka AS a me ka hana PC ke kaʻana like i nā mold, a ʻo nā huahana i hana ʻia he hana like loa. Eia nō naʻe, ʻaʻole hiki i ka PPSU a me TRITAN ke kaʻana like i nā ʻāpana no ka mea ʻokoʻa loa nā mea ʻelua. E palupalu ka PPSU i nā waiwai waiwai ʻē aʻe, no laila ʻaʻole hiki ke hoʻohana ʻia ka pahu pahu hoʻokahi no nā mea PPSU ke hoʻohana ʻia me ka mea AS. hoʻohana. ʻOi aku ka paʻakikī o ka mea TRITAN i hoʻohālikelike ʻia me nā mea ʻē aʻe. Pili ke kumu like. ʻAʻole kūpono nā ʻōpala kūpono no ka puhi ʻana i nā mea ʻē aʻe.
Eia nō naʻe, i mea e mālama ai i nā kumukūʻai, aia kekahi mau hale hana kīʻaha wai e kaʻana like i nā ʻōmole puhi ʻana no ka AS, PC, a me TRITAN, akā ʻaʻole maikaʻi nā huahana i hana ʻia. ʻAʻole e loiloi ʻia kēia.
