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

Ma nā ʻatikala mua, nā ʻokoʻa ma waena o nā mea plastik onā kīʻaha wai plastikua wehewehe ʻia, akā ʻaʻole i wehewehe ʻia ka hoʻohālikelike kikoʻī ma waena o nā mea PS a me AS.I ka hoʻohana ʻana i kahi papahana hou, ua hoʻohālikelike mākou i nā mea PS o nā kīʻaha wai plastik me E haʻi wau iā ʻoe i nā ʻokoʻa o nā mea AS.

Ma mua o ka hāʻawi ʻana, e ʻae mai iaʻu e kaʻana like i koʻu mau manaʻo pilikino i ke kākau ʻana i nā ʻatikala e pili ana i nā kīʻaha wai i nā makahiki.Ua hoʻomaka mākou e kākau i nā ʻatikala e pili ana i nā kīʻaha wai i ka makahiki 2022. Mai ka kākau kumu ʻole a hiki i kēia manawa, hiki iā mākou ke hoʻopaʻa ʻia i ka ʻike a me ka ʻepekema no kā mākou mau hoaaloha.Ma ke kākau ʻana i nā ʻatikala i nā makahiki, ua loaʻa iaʻu ka pōmaikaʻi nui, akā ʻo ke kākau ʻana he luuluu a me ka monotonous.Mai ka ʻeha o ka hiki ʻole ke kākau i nā ʻatikala maʻalahi a waiwai hoʻi i ka hoʻomaka ʻana, i ka ʻeha o ka hiki ʻole ke kākau i hoʻokahi ʻatikala i kēlā me kēia lā e like me nā lā mua.Ke piʻi mālie nei ka helu o nā hoaaloha e hahai ana iā mākou.Hoʻokomo maoli ʻia kekahi mau ʻatikala ma muli o ko lākou kūlana kiʻekiʻe, akā he nui nā ʻatikala ʻaʻole i manaʻo ʻia.Manaʻolana mākou e hahai mai nā hoaaloha makemake e kaʻana like i nā ʻatikala ma ka pūnaewele a hiki ke kōkua ma o nā ʻatikala.pūnaewele, a kōkua iā mākou e kaʻana like i nā ʻatikala āu e manaʻo ai he waiwai i hiki i nā hoaaloha ke ʻike iā lākou.Ma muli o ka pau ʻana o nā mea hoʻomohala ma ʻaneʻi, ke manaʻolana nei au e nīnau hou nā mea a pau i hoʻokahi nīnau a me nā mea e pili ana i nā kīʻaha wai a me nā ipu.Mahalo nui iā ʻoe no kāu kākoʻo.

Ma ka ʻatikala mua, ua haʻi wau i nā mea i hoʻohana ʻia i kēia manawa no nā kīʻaha wai plastik ma ka mākeke, e like me Tritan, PP, PPSU, PC, AS, a me nā mea ʻē aʻe.Ua launa pū au me kekahi mea kūʻai mai ʻEulopa i hui pū me nā mea PS no kā lākou pono kūʻai.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 ka paʻakikī, a ʻo kēia mea i loaʻa pālua nā kīʻaha wai i hana ʻia me ka phenol A a me nā mea PS ʻaʻole hiki ke hoʻopiha ʻia me ka wai wela wela, inā ʻaʻole. e hoʻokuʻu lākou i ka bisphenol A mea ʻino.

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 pale ʻana 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.
