ʻIkepili o ka ʻike olakino o PP, PC, PS, Tritan Plastic Water Bottle
Hiki ke ʻike ʻia nā ʻōmole wai plastik ma nā wahi a pau o ke ola.ʻAʻole hiki ke hāʻule, maʻalahi ka lawe ʻana, a me ke ʻano hiʻohiʻona, no laila nui ka poʻe e koho i nā ʻōmole wai plastik i ke kūʻai ʻana i nā hue wai.ʻO ka ʻoiaʻiʻo, ʻaʻole ʻike ka hapa nui o ka poʻe i ka mea o nā hue wai plastik, a ʻaʻole i nānā i ka hoʻokaʻawale ʻana a me ka palekana o nā mea hue wai, a ʻaʻole pinepine lākou i ka palekana o nā hue wai.
ʻO nā mea maʻamau no nā ʻōmole wai ʻili he Tritan, PP plastic, PC plastic, PS plastic.ʻO ka PC he polycarbonate, ʻo PP ka polypropylene, ʻo PS ka polystyrene, a ʻo Tritan kahi hanauna hou o nā mea copolyester.
ʻO PP kekahi o nā mea plastik palekana loa i kēia manawa.Hiki iā ia ke pale i nā wela kiʻekiʻe a hiki ke hoʻomehana ʻia i ka umu microwave.Loaʻa iā ia ke kūpaʻa wela maikaʻi, akā ʻaʻole ikaika, maʻalahi e haki, a he haʻahaʻa haʻahaʻa.
Loaʻa i nā mea PC ka bisphenol A, e hoʻokuʻu ʻia ke ʻike ʻia i ka wela.ʻO ka lawe lōʻihi ʻana i ka nui o ka bisphenol A e hōʻeha i ke olakino kanaka.Ua kapu a pāpā paha kekahi mau ʻāina a me nā ʻāina i ka PC.
ʻO ka mea PS he mea me ka ʻikea kiʻekiʻe loa a me ka ʻōlinolino kiʻekiʻe.He mea maʻalahi ke paʻi, a hiki ke kala ʻole ʻia, ʻaʻohe ona, ʻono ʻole, ʻona ʻole, ʻaʻole ia e ulu i ka haʻi.No laila, ua lilo ia i hoʻokahi o nā mea plastik kaulana loa.
Ke kū nei nā mea hana i ke kaomi o ke olakino a me ka palekana o ke kaiapuni a ke ʻimi nei i nā mea hiki ke pani i ka PC.
Ma kēia mākeke kūʻai, ua hoʻomohala ʻo Eastman o ʻAmelika i kahi hanauna hou o ka copolyester Tritan.He aha kona mau pono?
1. ʻO ka permeability maikaʻi, ka transmittance māmā> 90%, haze <1%, me ka luster e like me ke aniani, no laila ʻo ka ʻōmole Tritan he akaka a maopopo loa e like me ke aniani.
2. Ma ke ʻano o ke kūpaʻa kemika, ʻoi aku ka maikaʻi o nā mea Tritan, no laila hiki ke hoʻomaʻemaʻe ʻia a hoʻomaʻemaʻe ʻia nā hue Tritan me nā mea holoi like ʻole, ʻaʻole lākou makaʻu i ka corrosion.
3. ʻAʻole i loaʻa nā mea ʻino a hoʻokō i nā koi o ka palekana o ke kaiapuni a me ke olakino;paʻakikī maikaʻi, ikaika hopena kiʻekiʻe;pale wela kiʻekiʻe ma waena o 94 ℃-109 ℃.
