He aha nā ʻokoʻa ma waena o nā mea PS a me nā mea AS o nā kīʻaha wai plastik

He aha nā mea i hoʻohana ʻia i kēia manawa no nā kīʻaha wai plastik ma ka mākeke, e like me Tritan, PP, PPSU, PC, AS, etc. ʻAʻole i haʻi pinepine ʻia ʻo PS he mea maʻamau no nā kīʻaha wai plastik. Ua hui pū au me nā pono kūʻai o kahi mea kūʻai mai ʻEulopa. Ua loaʻa i ka mea hoʻoponopono nā mea PS. Ua ʻike nā hoaaloha he nui i ke kālepa ʻē aʻe ke hoʻokō nei ka mākeke holoʻokoʻa o ʻEulopa, e like me Kelemania, i nā kauoha hoʻopaʻa paʻa. ʻO ke kumu, ʻaʻole maʻalahi ka hoʻoheheʻe ʻana a me ka hana hou ʻana i nā mea plastik, a he nui nā mea plastik i loaʻa ka bisphenol A, hiki ke hōʻeha i ke kino o ke kanaka ma hope o ka hana ʻana i kīʻaha wai. No ka laʻana, pāpā ʻia nā mea PC, ʻoiai ʻoi aku ka maikaʻi ma mua o AS a me PS ma kekahi mau hiʻohiʻona hana, mai ka mākeke ʻEulopa no ka hana ʻana i nā hue wai no ka mea aia lākou i ka bisphenol A.

ʻO PS, ma ka ʻōlelo a ka poʻe kamaʻāina, he resin thermoplastic ʻaʻole waihoʻoluʻu a ʻākala me ka transmittance kiʻekiʻe. Ke hoʻohālikelike ʻia me nā mea plastik i ʻōlelo ʻia ma luna nei, ʻo kāna kumu kūʻai haʻahaʻa haʻahaʻa kona pono, akā he palupalu ʻo PS a he ʻilihune paʻakikī, a ʻo kēia mea i loaʻa i nā kīʻaha wai pālua i hana ʻia me ka phenol A a me nā mea PS ʻaʻole hiki ke hoʻopiha ʻia me ka wai wela wela, i ʻole. e hoʻokuʻu lākou i nā mea bisphenol Aharmful.

ʻO AS, acrylonitrile-styrene resin, kahi mea polymer, kala ʻole a me ka ʻike, me ka transmittance kiʻekiʻe. Ke hoʻohālikelike ʻia me PS, ʻoi aku ka paʻa o ka hāʻule ʻana, akā ʻaʻole paʻa, ʻoi aku ka maikaʻi ʻaʻole kū i nā ʻokoʻa wela. Inā ʻoe e hoʻohui koke i ka wai anuanu ma hope o ka wai wela, e ʻike ʻia ka ili o ka mea inā ʻike ʻia ka māhā, e pohā nō hoʻi ke waiho ʻia i loko o ka friji. ʻAʻole i loko o ka bisphenol A. ʻOiai ʻo ka hoʻopiha ʻana iā ia me ka wai wela e haki ai ke kīʻaha wai, ʻaʻole ia e hoʻokuʻu i nā mea ʻino, no laila hiki iā ia ke hele i ka hoʻokolohua EU. ʻOi aku ke kumukūʻai waiwai ma mua o PS.
Pehea e hoʻoholo ai mai ka huahana i hoʻopau ʻia inā hana ʻia ke kīʻaha wai me ka mea PS a i ʻole AS? Ma o ka nānā ʻana, hiki ke ʻike ʻia ʻo ke kīʻaha wai waihoʻoluʻu a ʻākala i hana ʻia i kēia mau mea ʻelua e hōʻike maoli i kahi hopena polū. Akā inā makemake ʻoe e hoʻoholo pono inā he PS a i ʻole AS, pono ʻoe e hoʻohana i nā mea hoʻāʻo ʻoihana.
