Hoʻolauna i Kekahi Mau Mahele Plastics

Ka Ikepili o ka ʻikepili Ola no PP, PC, PS, ʻōmole wai lula plastik Tritan

Hiki ke ʻike ʻia nā ʻōmole wai lula ma nā wahi āpau o ke ola. Kūpale nā ​​ʻōmole wai palakiko i ka hāʻule, maʻalahi e lawe, a me ke ʻano i ka helehelena, no laila he nui ka poʻe e koho i nā hue wai palolo ke kūʻai ʻana i nā ʻōmole wai. I ka ʻoiaʻiʻo, ʻaʻole ʻike ka hapa nui o ka poʻe i nā mea o nā hue wai palolo, a ʻaʻole nānā pinepine i ka hoʻonohonoho ʻana a me ka palekana o nā mea ʻōmole wai, a nānā pinepine ʻole i ka palekana o nā ʻōmole wai.

ʻO nā mea hana maʻamau no nā ʻōmole wai lula ʻo Tritan, PP ea, PC ea, PS ea. ʻO PC ka 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 ea palekana loa i kēia manawa. Hiki iā ia ke kū i ke ana wela a hiki ke wela i ka umu umu. He maikaʻi ke kūpaʻa wela, akā ʻaʻole ikaika, maʻalahi e haki, a haʻahaʻa haʻahaʻa hoʻi.

Loaʻa i nā mea PC ka bisphenol A, e hoʻokuʻu ʻia ke hōʻike ʻia i ka wela. ʻO ka lawe lōʻihi ʻana o nā huina o ka bisphenol A e hōʻeha i ke olakino kanaka. Ua kapu a pāpā paha kekahi mau ʻāina a me nā ʻāina iā PC.

ʻO nā mea PS kahi mea me ka mālamalama kiʻekiʻe loa a me ka gloss kiʻekiʻe. Maʻalahi e paʻi, a hiki ke kala manuahi, ʻaʻohe pilau, ʻono ʻole, ʻaʻohe mea ʻawahia, a ʻaʻole kumu o ka ulu ʻana o ka fungus. No laila, ua lilo ia i kekahi o nā mea ea i makemake nui ʻia.

Ke kū nei nā mea hana i ke kaomi o ke olakino a me ka pale o ke kaiapuni a ke ʻimi nei i nā mea i hiki ke pani i ka PC.

Ma kēia mākeke ma hope, ua hoʻomohala ʻo Eastman o ʻAmelika Hui Pū ʻIa i kahi hanauna hou o copolyester Tritan. He aha nā mea maikaʻi?

1. permeability maikaʻi, transmittance kukui> 90%, haze <1%, me ka aniani e like me ke aniani, no laila ke aniani a akāka loa ka ʻōmole Tritan e like me ke aniani.

2. Ma nā ʻōlelo kūpaʻa kemika, noho ʻo Tritan i kahi pono kūpono loa, no laila hiki ke hoʻomaʻemaʻe a disinfected nā ʻōmole Tritan me nā detergents like ʻole, a makaʻu ʻole lākou i ka popopo.

3. ʻAʻohe ona mea ʻinoʻino a kū i nā koina o ka pale ʻana i ke kaiapuni a me ke olakino; ʻoʻoleʻa maikaʻi, ikaika hopena kiʻekiʻe; ke kūpaʻa wela kiʻekiʻe ma waena o 94 ℃ -109 ℃.
