He aha ka Polycarbonate?
ʻO ka Polycarbonate (PC) kahi mea polymer i hoʻohana nui ʻia i ka ʻoihana kemika a ʻo ia kekahi o nā mea i makemake nui ʻia i nā ʻoihana he nui ma muli o kāna mau waiwai kino a me nā mea kemika. Ma kēia ʻatikala, e loiloi mākou i nā kikoʻī i ka haku mele a me nā waiwai o ka Polycarbonate a me kāna ākea ākea.
1. ʻO ka haku mele a me ke ʻano o ka polycarbonate
ʻO ka polycarbonate kahi papa o ka bisphenol A (BPA) a me nā hui carbonate ma o ka hopena polycondensation i hana ʻia e ka polymer linear. Loaʻa i kāna kaulahao molekala ka nui o nā pūʻulu carbonate (-O-CO-O-), hāʻawi kēia ʻano i ka polycarbonate me ka pale wela maikaʻi loa, ka ʻike a me ke kūpaʻa hopena. ʻO ka paʻa kemika o ka polycarbonate e hiki ai iā ia ke mālama i kona mau waiwai i loli ʻole i nā kaiapuni koʻikoʻi, e lilo ia i mea paʻa loa.
2. Nā waiwai nui o ka polycarbonate
ʻIke ʻia ka mea polycarbonate no kāna mau waiwai kino maikaʻi. Loaʻa iā ia ke kūpaʻa hopena kiʻekiʻe, 250 mau manawa ma mua o ke aniani maʻamau, ka mea e kaulana ai ka polycarbonate i nā noi e koi ai i ka ikaika kiʻekiʻe a me ka hopena hopena. ʻO ka polycarbonate ka pale wela maikaʻi loa, e noho paʻa ana mai -40 ° C a 120 ° C, e hiki ai ke hana maikaʻi i nā wahi wela kiʻekiʻe. ʻO ka Polycarbonate kekahi ʻano aniani ʻike maikaʻi, e hoʻouna ana ma mua o 90 pakeneka o ka mālamalama ʻike ʻia, no laila hoʻohana pinepine ʻia i ka hana ʻana i nā lens optical a me nā uhi aniani.
3. Nā wahi noi o ka polycarbonate
Ma muli o nā waiwai kūikawā o nā mea polycarbonate, hoʻohana nui ʻia i nā ʻoihana like ʻole. I ka ʻoihana kūkulu, hoʻohana pinepine ʻia ka polycarbonate e hana i nā paneli māmā, nā mea hale a me nā panela acoustic. ʻO kona kūpaʻa hopena maikaʻi loa a me ka ʻike maopopo he mea nui ia i kēia mau wahi. I ka ʻāpana uila a me ka uila, hoʻohana ʻia ka polycarbonate e hana i nā ʻāpana uila, nā hale pono hale a me nā hihia pākaukau ma muli o kona kūpaʻa wela a me nā waiwai insulation uila. Hoʻohana nui ʻia ka polycarbonate i ka ʻoihana kaʻa, ka mea nui no nā pale kukui, nā panela mea kani a me nā puka makani. ʻO ka mea nui aku, hoʻohana nui ʻia ka polycarbonate ma ke kahua o nā lāʻau lapaʻau, e like me nā syringes, nā mea hana dialysis a me nā mea ʻokiʻoki, a me nā mea ʻē aʻe.
4. Kaiapuni a me Recycled Polycarbonate
ʻOiai ʻo ka polycarbonate he mea lōʻihi a maʻalahi hoʻi, ʻo ka bisphenol A (BPA) i komo i kāna hana i hoʻokumu i kekahi mau hoʻopaʻapaʻa kaiapuni. I ka holomua ʻana o ka ʻenehana, ua hoʻomohala ʻia nā huahana polycarbonate maikaʻi loa e hōʻemi i ka hopena i ke kaiapuni. ʻO ka hana hou ʻana o ka polycarbonate ke loaʻa lohi nei ka manaʻo, a ma o ke kaʻina hana hou, hiki ke hoʻololi ʻia nā mea ʻōpala polycarbonate i nā huahana hou e hōʻemi hou i ka ʻōpala kumu.
Ka hopena
He aha ka polycarbonate? He mea polymer me nā ʻano hiʻohiʻona kiʻekiʻe, a ua hoʻohana nui ʻia i ke kūkulu ʻana, nā mea uila a me nā mea uila, nā kaʻa, nā lāʻau lapaʻau a me nā ʻano ʻē aʻe ma muli o ka hopena o ka hopena, ka pale wela, ka ʻike a me ke kūpaʻa kemika. Me ka hoʻonui ʻana i ka ʻike o ka mālama ʻana i ke kaiapuni, ke hoʻolaha ʻia nei ka hana hou ʻana o ka polycarbonate. ʻO ka Polycarbonate kahi mea i kūpono a hiki ke hoʻomohala mau.
