He mau tausani kīʻaha wai plastik, he aha nā mea āu e koho ai e palekana? I kēia manawa, ʻelima mau mea nui no nā kīʻaha wai plastik ma ka mākeke: PC, tritan, PPSU, PP, a me PET.
❌ ʻAʻole hiki ke koho: PC, PET (mai koho i nā kīʻaha wai no nā mākua a me nā pēpē)
Hiki i ka PC ke hoʻokuʻu maʻalahi i ka bisphenol A ke wela, a hiki i ka bisphenol A ke hoʻoulu i nā maʻi endocrine, keʻakeʻa i ka ʻōnaehana hānau, a hoʻoulu i ka wā ʻōpio mua i nā keiki. He lāʻau D maʻi maʻi ma waho a ma waho!
He 65 ℃ ka pale wela o ka PET. Ke hoʻonui ʻia ka mahana i koho ʻia, hiki iā ia ke hoʻokuʻu maʻalahi i nā mea ʻino. Ua ʻike ʻia ka noiʻi ʻepekema hiki i nā huahana plastik PET ke hoʻokuʻu i nā carcinogens i loko o hoʻokahi mahina o ka hoʻohana ʻana a he mea ʻawaʻawa i nā testicles kāne.
✅Aia ke koho: Tritan, PPSU, PPTritan mea ole bisphenol A, bisphenol S a i ole kekahi mea bisphenol, a palekana loa. Eia nō naʻe, ʻo ka pale wela o ka tritan he -10-96 ° C, no laila ʻaʻole pono e hoʻokomo i ka wai wela 100-degree.
ʻO ka PPSU kahi mea palekana hou, polyphenylsulfone, ʻaʻole i loaʻa i ka bisphenol A. ʻO kona ʻano i loko he paʻa paʻa a hiki ke kū i ka sterilization kiʻekiʻe kiʻekiʻe 180-degere. ʻOi aku ka pale ʻana i ka hāʻule ʻana, no ka mea he māmā ke kino o ka ʻōmole a ʻaʻole maʻalahi e haki.
ʻAʻole e hoʻopuka nā ʻōmole pēpē a me nā kīʻaha wai me nā mea ppsu i nā mea ʻona ma hope o ka hoʻomaʻamaʻa pinepine ʻana i ka wela wela. ʻAʻole lākou i loko o ka bisphenol A a hiki ke kū i nā wela kiʻekiʻe o 180 degere. No laila, inā maʻa ʻoe i ka mālama ʻana i ka wai wela a i ʻole ka disinfection kiʻekiʻe, ʻo ka mea PPSU ke koho mua.
ʻO nā kīʻaha wai plastik PP i hana ʻia me ka polypropylene, nona ka paʻa wela maikaʻi a me ka insulation, palekana a maikaʻi ʻole i ke kino kanaka. Eia nō naʻe, pono e hoʻomaopopo ʻia ʻaʻole hiki ke puhi ʻia nā kīʻaha wai i hana ʻia i ka PP i nā mahana kiʻekiʻe no ka manawa lōʻihi, i ʻole e maʻalahi lākou i ka ʻelemakule.
E nānā kākou i ka mea i hana ʻia ai kāu kīʻaha wai?
