Pono au e koho i ka PC a i ʻole PP no nā kīʻaha wai plastik?

Nui nā ʻano kīʻaha wai ʻilika, a he mea hiki ʻole ke hoʻohilahila ʻia mākou i ke koho ʻana i nā kīʻaha wai plastik.

I mea e ʻike hou aku ai nā mea a pau e pili ana i nā kīʻaha wai plastik a hiki iā lākou ke koho i kā lākou mau kīʻaha wai plastik punahele, e ʻae mai iaʻu e nānā i ka hoʻolauna ʻana iā ʻoe i nā ʻokoʻa ma waena o PC a me PP i nā mea kīʻaha wai plastik.

ʻO PC ka pōkole English o polycarbonate, kekahi o nā plastics maʻamau.ʻAʻole ʻona kēia mea a hoʻohana pono ʻia no ka hana ʻana i nā ʻōmole pēpē, nā kīʻaha ākea, a me nā mea ʻē aʻe.

Ma ke kumumanaʻo, ʻoiai ka lōʻihi o ka 100% o ka bisphenol-A i hoʻololi ʻia i loko o kahi ʻano plastik i ka wā o ka hana ʻana o ka polycarbonate, ʻo ia hoʻi ʻaʻohe bisphenol-a i loko o ka huahana, ʻaʻohe pilikia i ke olakino.Eia nō naʻe, inā ʻaʻole i hoʻololi ʻia nā liʻiliʻi o ka BPA i loko o ke ʻano palaki o ka polycarbonate, hiki ke hoʻokuʻu ʻia i loko o nā meaʻai a i ʻole nā ​​​​mea inu, e hoʻoweliweli ana i ke olakino a me ka palekana o nā mea hoʻohana, ʻoi aku ka poʻe ʻōpio.

ʻO PP ka ʻōlelo Pelekane o ka polypropylene a maikaʻi ke kūpaʻa wela.Hiki ke sterilized ka huahana ma nā mahana ma luna o 100 degere Celsius a ʻaʻole e deform ma 150 degere Celsius me ka ʻole o ka ikaika o waho.
ʻO ka polypropylene kekahi o nā plastics i hoʻohana pinepine ʻia i nā umu microwave.Eia naʻe, ma hope o ka hoʻokolokolo pono ʻana, e ʻike mākou ʻoi aku ka nui o ka polycarbonate ma ka mākeke ma mua o nā huahana polypropylene, a makemake nā mea kūʻai aku e hahai i ka manaʻo o "ʻoi aku ka pipiʻi, ʻoi aku ka maikaʻi o ka maikaʻi".ʻO kaʻoiaʻiʻo, ʻo ka ʻokoʻa o ke kumukūʻai no ka mea ʻoi aku ka kiʻekiʻe o ke kumukūʻai o kēia manawa o ka ton o polycarbonate ma ka mākeke ma mua o ke kumu kūʻai o ka ton o polypropylene.

I ka hoʻohālikelike ʻana i nā mea ʻelua, hiki ke ʻike ʻia he ʻoi aku ka maikaʻi o ka pale ʻana o ka polypropylene ma mua o ka polycarbonate, no laila, i ka hana ʻana i nā kīʻaha aniani, hoʻohana ʻia ka polycarbonate ma ke ʻano he mea.ʻOi aku ka nani o nā huahana polycarbonate ma mua o nā huahana polypropylene.Eia nō naʻe, mai kahi ʻike palekana, hiki i ka mahana hana o ka plastic polypropylene i 170 ~ 220 degere Celsius, no laila ʻaʻole hiki ke hoʻoheheʻe ʻia ka wai paila, no laila ʻoi aku ka palekana o ka polypropylene ma mua o ka polycarbonate.
