He aha ka mea PC?
ʻO nā mea PC, a i ʻole Polycarbonate, he mea polymer i hoʻokipa i ka nānā ʻana no kāna mau waiwai kino maikaʻi a me ka laulā o nā noi. Ma kēia ʻatikala, e nānā pono mākou i nā waiwai kumu o nā mea PC, kā lākou noi nui a me kā lākou mea nui i ka ʻoihana kemika.
Nā waiwai kumu o nā mea PC
Ua ʻike ʻia ʻo Polycarbonate (PC) no kona ikaika maikaʻi loa a me ka pale ʻana i ka hopena. Ke hoʻohālikelike ʻia me nā plastics ʻē aʻe he nui, he kiʻekiʻe kiʻekiʻe loa ka PC o ka māliko a me nā waiwai optical maikaʻi, kahi e kūpono ai no nā huahana e like me nā lako optical, nā ipu aniani a me nā hōʻike. ʻO ka pc ka maikaʻi o ka pale wela a hiki ke noho paʻa me ka ʻole o ka deformation ma nā mahana a hiki i 120°C. Loaʻa i ka mea waiwai nā waiwai insulation uila maikaʻi. Loaʻa i ka mea waiwai nā waiwai insulation uila, ʻo ia ke kumu i hoʻohana nui ʻia ai i ka ʻoihana uila a me ka uila.
Nā wahi o ka noi no nā mea PC
Ma muli o kāna mau waiwai kino a me nā kemika maikaʻi loa, hoʻohana ʻia ʻo PC i nā ʻano noi. Ma nā mea uila uila, hoʻohana ʻia ʻo PC e hana i nā hale kelepona paʻa, nā pahu kamepiula, a me nā mea ʻē aʻe, no ka mea he māmā a ikaika hoʻi. I ke kūkulu ʻana a me nā ʻoihana kaʻa, hoʻohana ʻia ʻo PC e hana i nā kukui, nā pale makani, nā ʻikeʻike hale, a me nā ʻāpana ʻē aʻe ma muli o kona ikaika kiʻekiʻe a me ke kūʻē ʻana i nā kukuna UV a me ka wā ʻino, a loaʻa iā ia nā noi koʻikoʻi i nā lāʻau lapaʻau a me nā meaʻai. ʻO ka biocompatibility a me ka lōʻihi e hana ia i mea e kū ai i nā koi palekana koʻikoʻi.
ʻO ka hana kemika a me ka hana ʻana o nā mea PC
Ma kemika, hoʻopili ʻia nā mea PC ma o ka hopena polycondensation ma waena o ka bisphenol A a me ka carbonate. Hāʻawi ke kaulahao molekala o kēia polymer iā ia i nā waiwai mechanical maikaʻi loa a me ke kūpaʻa wela. Ma ke ʻano o ka ʻenehana hana, hiki ke hoʻoheheʻe ʻia nā mea PC e nā ʻano like ʻole e like me ka injection molding, extrusion and blow moulding. Hāʻawi kēia mau kaʻina hana i nā mea PC e hoʻololi i nā pono hoʻolālā o nā huahana like ʻole, me ka hōʻoia ʻana ʻaʻole i hōʻino ʻia nā waiwai kino o ka mea.
Kaiapuni a me ka hoʻomau o nā mea PC
ʻOiai ka nui o nā pono o nā mea PC, ua hāpai ʻia nā hopohopo kaiapuni. Hana pinepine ʻia nā mea PC kuʻuna mai nā mea waiwai petrochemical, kahi e hoʻoikaika ai ka hoʻomau. I nā makahiki i hala iho nei, ua hoʻomohala ikaika ka ʻoihana kemika i nā polycarbonates bio-based e hōʻemi i ko lākou hopena kaiapuni. ʻAʻole kēia mea PC hou e hōʻemi wale i ka hoʻokuʻu kalapona, akā hoʻonui pū i ka recyclability o ka mea ʻoiai e mālama ana i kona mau waiwai kino maoli.
Hōʻuluʻulu manaʻo
He aha ka mea PC? I ka pōkole, ʻo ka mea PC kahi mea polycarbonate polymer e noho ana i kahi kūlana koʻikoʻi i kekahi mau ʻoihana ma muli o kāna mau waiwai kino maikaʻi a me ka nui o nā mea noi. Inā ma nā mea uila uila, kūkulu hale, ʻoihana automotive a i ʻole nā ​​​​mea lapaʻau, ua hōʻike ka noi o nā mea PC i kona waiwai hiki ʻole ke hoʻololi. Me ka hoʻonui ʻana i ka ʻike kaiapuni a me ka holomua ʻenehana, ke neʻe nei nā mea PC i kahi ʻoi aku ka hoʻomau a me ka hoʻopili ʻana i ke kaiapuni a e hoʻomau i ka hana nui i ka ʻoihana kemika i ka wā e hiki mai ana.
