I ke aupuni o ka ʻoihana hou, ua lilo nā mea lāʻau lapaʻau i mea nui loa ma muli o ko lākou mau waiwai kūʻokoʻa e like me ka elasticity, ka pale ʻana i ka lole, a me ke kūpaʻa kemika. Ma waena o kēia mau mea, ʻo ka pulupulu fluorine (FKM) a me ka rubber perfluoroether (FFKM) e kū nei ma ke ʻano he mau lāʻau hana kiʻekiʻe, kaulana no ko lākou kemika maikaʻi a me ke kūpaʻa wela kiʻekiʻe. ʻIke ʻia kēia ʻikepili piha i nā ʻokoʻa, nā noi, nā kumukūʻai, nā ʻano, a me nā waiwai o FKM a me FFKM, me ka manaʻo e hāʻawi i nā ʻike waiwai no nā mea pili i nā ʻoihana pili.
Nā ʻokoʻa kumu ma waena o ka Rubber Fluorine (FKM) a me ka Rubber Perfluoroether (FFKM)
Hoʻolālā Kimia
Aia ka ʻokoʻa nui ma waena o FKM a me FFKM i kā lākou mau hana kemika. ʻO ka FKM he polimer fluorina ʻāpana me nā paʻa kalapona-kāpona (CC) ma kona kaulahao nui, aʻo FFKM he polimer fluorina piha me kahi ʻano kalapona-oxygen-carbon (COC), i hoʻohui ʻia e nā ʻātoma oxygen (O). ʻO kēia ʻano ʻano like ʻole赋予FFKM ʻoi aku ka maikaʻi a me ke kūpaʻa wela kiʻekiʻe i hoʻohālikelike ʻia me FKM.
Palekana Kemika
ʻO ke kaulahao koʻikoʻi o FFKM, me ka ʻole o nā paʻa kalapona-carbon, hāʻawi i ka hoʻoikaika ʻana i ke kūʻē ʻana i ka media kemika. E like me ka mea i hōʻike ʻia ma ke kiʻi e pili pū ana, ʻo ka ikehu paʻa o nā paʻa carbon-hydrogen ka haʻahaʻa loa (ma kahi o 335 kJ/mol), hiki ke hoʻemi i ka FKM i nā mea hoʻokahe ikaika a me nā mea hoʻoheheʻe polar i hoʻohālikelike ʻia me FFKM. Kūpaʻa ʻo FFKM i ka ʻaneʻi a pau i ʻike ʻia me nā ʻakika ikaika, nā kumu, nā mea hoʻoheheʻe organik, a me nā mea ʻokiʻoki.
Kū'ē Kūlana Kiʻekiʻe
ʻOi aku hoʻi ʻo FFKM i ka pale ʻana i ka wela kiʻekiʻe. ʻOiai ʻo ka mahana hana mau o FKM mai ka 200-250°C, hiki iā FFKM ke pale i nā mahana a hiki i 260-300°C. ʻO kēia kūpaʻa wela kiʻekiʻe e kūpono i ka FFKM no nā noi i nā kaiapuni koʻikoʻi.
Nā kahua noi
ʻO ka Rubber Fluorine (FKM)
Hoʻohana nui ʻia ʻo FKM ma nā ʻano hana like ʻole ma muli o kona kūpaʻa kemika maikaʻi loa a me ke kūpaʻa haʻahaʻa kiʻekiʻe.
- ʻOihana Kaʻa: Hoʻohana ʻia ʻo FKM i ka hana ʻana i nā sila, nā sila ʻaila, nā apo-O, a me nā mea hou aku, ʻoi aku ka nui o nā mīkini a me nā ʻōnaehana hoʻouna.
- ʻOihana Kemika: Hoʻohana ʻia ʻo FKM no nā sila i loko o nā paipu, nā kiwi, nā ʻōpala, a me nā mea hana ʻē aʻe e pale ai i ka leakage media kemika.
- ʻOihana Electronics: Hoʻohana ʻia ia no nā papa insulation i nā uea a me nā kaula, ʻoi aku hoʻi i nā kaiapuni kiʻekiʻe-mehana a me nā kemika.
ʻO ka Rubber Perfluoroether (FFKM)
Hoʻohana ʻia ʻo FFKM ma nā kula e koi ana i ke kūʻē kemika a me ka wela kiʻekiʻe:
- Aerospace: Hoʻohana ʻia ʻo FFKM no nā sila i nā mokulele a me nā mokulele e hoʻomanawanui i nā wela wela a me nā kaiapuni kemika.
- ʻOihana Semiconductor: Hoʻohana ʻia ia no nā sila i nā mea hana semiconductor e pale ai i ka leakage kinoea.
- ʻOihana Petrochemical: Hoʻohana ʻia ʻo FFKM no nā sila i nā mea wela kiʻekiʻe a me nā mea hana kiʻekiʻe i nā mea hoʻolaʻa aila a me nā mea kanu kemika.
Kumukuai a me ke Kumukuai
ʻO ke kumu kūʻai kiʻekiʻe o ka FFKM i loaʻa i ke kumu kūʻai makeke ʻoi aku ka kiʻekiʻe ma mua o FKM. ʻO ka paʻakikī o nā lako maka a me nā kaʻina hana o ka FFKM e hoʻonui i kona kumukūʻai. Eia nō naʻe, hāʻawi ʻia ka hana maikaʻi o FFKM i nā kaiapuni koʻikoʻi, kūpono ke kumu kūʻai kiʻekiʻe ma kekahi mau noi.
Keʻano a me ka hana
ʻO ka Rubber Fluorine (FKM)
Hāʻawi maʻamau ʻia ka FKM ma ke ʻano he lāʻau paʻa, ka lāʻau hui, a i ʻole nā ʻāpana i hana mua ʻia. ʻO kāna mau ʻano hana e pili ana i ka compression molding, extrusion, a me ka injection molding. Pono ʻo FKM i nā mea hana kūikawā a me nā ʻāpana kaʻina hana ma muli o kona kiʻekiʻe kiʻekiʻe.
ʻO ka Rubber Perfluoroether (FFKM)
Hoʻolako pū ʻia ka FFKM ma ke ʻano o ka lāʻau paʻa paʻa, ka ʻōpala hui, a i ʻole nā ʻāpana i hana mua ʻia. ʻO kona kūpaʻa wela kiʻekiʻe e pono ai i nā mahana hana kiʻekiʻe a me nā pono hana paʻa a me nā koi.
Hoʻohālikelike Hana
Palekana Kemika
ʻOi aku ka maikaʻi o ka pale kemika o FFKM ma mua o ko FKM. Kūpaʻa ʻo FFKM i ka ʻaneʻi a pau i ʻike ʻia me nā ʻakika ikaika, nā kumu, nā mea hoʻoheheʻe organik, a me nā mea ʻokiʻoki. ʻOiai ke hāʻawi nei ʻo FKM i ke kūpaʻa kemika maikaʻi, ʻoi aku ka maikaʻi o kekahi mau mea hoʻoheheʻe ikaika a me nā mea hoʻoheheʻe polar i hoʻohālikelike ʻia me FFKM.
Kū'ē Kūlana Kiʻekiʻe
ʻOi aku ka maikaʻi o ka pale wela kiʻekiʻe o FFKM ma mua o ko FKM. ʻO ka mahana hana mau o FKM he 200-250°C, ʻoiai hiki i ka FFKM ke hiki i 260-300°C. ʻO kēia kūpaʻa wela kiʻekiʻe e hoʻohana nui i ka FFKM i nā kaiapuni koʻikoʻi.
Hana Mechanical
Loaʻa iā FKM a me FFKM nā waiwai mechanical maikaʻi loa, me ka elasticity kiʻekiʻe, ke kūpaʻa ʻaʻahu, a me ke kūpaʻa waimaka. Eia naʻe, ʻoi aku ka paʻa o nā waiwai mechanical o FFKM i nā wela kiʻekiʻe, e ʻoi aku ka hilinaʻi i nā noi wela kiʻekiʻe.
Nā Manaʻo Makeke
Me ka hoʻomau mau ʻana o ka ʻenehana ʻenehana, ke piʻi nei ka noi no nā mea hoʻonaninani kiʻekiʻe. Loaʻa iā FKM a me FFKM nā manaʻo noiʻi ākea ma nā ʻano hana like ʻole ma muli o kā lākou hana maikaʻi loa:
- ʻOihana Automotive: Ke hoʻonui nei ka hoʻomohala ʻana i nā kaʻa ikehu hou i ka noi no ke kūpaʻa kiʻekiʻe a me ka chemically corrosion-resistant sila, e hoʻonui hou i ka noi o FKM a me FFKM.
- ʻOihana Kemika: Ke hoʻonui nei ka ʻokoʻa a me ka paʻakikī o nā huahana kemika i ka noi no nā sila kūpaʻa kemika, e hoʻonui hou i ka noi o FKM a me FFKM.
- Electronics Industry: Ke hoʻonui nei ka miniaturization a me ka hana kiʻekiʻe o nā mea uila i ka noi no nā mea insulating i kū i ke kiʻekiʻe kiʻekiʻe a me ka corrosion kemika, e hoʻonui hou i ka noi o FKM a me FFKM.
Ka hopena
ʻO ka lāʻau fluorine (FKM) a me ka lāʻau perfluoroether (FFKM), ma ke ʻano he mau ʻelele o nā ʻōpala hana kiʻekiʻe, loaʻa nā manaʻo noiʻi ākea ma nā ʻano ʻano like ʻole ma muli o ko lākou kūpaʻa kemika maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe. ʻOiai ʻoi aku ka pipiʻi o ka FFKM, ʻo kāna hana koʻikoʻi i nā kaiapuni koʻikoʻi e hāʻawi iā ia i kahi pōmaikaʻi hiki ʻole ke hoʻololi ʻia i kekahi mau noi. Me ka hoʻomau mau ʻana o ka ʻenehana ʻenehana, e piʻi mau ana ka noi no nā mea hana kiʻekiʻe o ka lāʻau lapaʻau, a ākea ka mākeke no FKM a me FFKM.
