ʻO ka hoʻohana ʻana i nā mea plastic ma nā ʻano ʻokoʻa
I nā makahiki i hala iho nei, me ka hoʻomohala wikiwiki ʻana o ka ʻepekema a me ka ʻenehana a me ka ʻenehana ʻenekinia, ua lilo nā mea plastic i mea waiwai nui a koʻikoʻi i nā ʻano hana like ʻole. Mai nā lāʻau lapaʻau i ka hana ʻana i nā kaʻa, mai nā mea kūkulu hale a i nā mea uila, pāʻani nui nā plastics.
Ma ke kahua lapaʻau, hoʻohana nui ʻia nā mea palaki lāʻau lapaʻau i nā lāʻau lapaʻau, hoʻopili olakino a me nā mea lapaʻau. ʻO kona kūpaʻa corrosion maikaʻi loa, ka plasticity a me ka biocompatibility e lilo ia i mea koho no ka hana ʻana i nā mea lapaʻau. Eia kekahi, hoʻohana ʻia nā mea silicone palupalu i ka hana ʻana i nā prostheses a me nā lako olakino e lawe mai i nā mea maʻi i kahi ʻoi aku ka maikaʻi o ka mālama ʻana a me ka hoʻoponopono hou ʻana.
I ke kahua o ka hana kaʻa, hoʻohana nui ʻia nā plastic plastic i nā ʻāpana o loko, nā ʻāpana mīkini a me ke ʻano o ke kino. ʻO kona māmā māmā, ikaika kiʻekiʻe a me ke kūpaʻa ʻana i ke kaʻa e ʻoi aku ka mālama ʻana i ka ikehu, pili kaiapuni, palekana a hilinaʻi. Eia kekahi, hoʻohana nui ʻia nā mea polyurethane foam i nā noho kaʻa a me nā ʻōnaehana haʻalulu e hoʻomaikaʻi i ka ʻoluʻolu a me ka palekana.
I ka ʻoihana kūkulu, hoʻohana ʻia nā mea plastic i ka hana ʻana i nā kiʻi puka a me ka puka makani, nā paipu wai a me nā mea insulation. Ma muli o kona kūpaʻa ikaika o ka wā, ka hana maʻalahi a me nā waiwai insulation thermal maikaʻi, hoʻokani nā huahana plastic i kahi kuleana nui i nā mea kūkulu hale, hāʻawi i ke kākoʻo ikaika no ka hoʻomohala ʻana i ka ʻoihana kūkulu.
Ma ke kahua o nā huahana uila, hoʻohana nui ʻia nā plastics engineering a me nā mea silicone i nā hihia kelepona paʻa, nā ʻāpana uila a me nā mea insulation. ʻAʻole i loaʻa i kēia mau mea pono nā waiwai mechanical maikaʻi, akā hiki ke hoʻokō i nā pono kūikawā o nā huahana uila no ke kūpaʻa kiʻekiʻe o ka mahana, ka wai a me ka lepo lepo, e hāʻawi ana i nā mea hou aku no ka hoʻolālā a me ka hana ʻana i nā huahana uila.
Hiki ke ʻike mua ʻia me ka holomua mau o ka ʻepekema a me ka ʻenehana, e pāʻani nui nā mea plastic i nā kula hou aʻe a hana i kahi nohona maikaʻi aʻe a me ka hana ʻana no nā kānaka.
