I ke ao o ka ʻoihana hou, ua lilo nā mea laholio i mea nui loa ma muli o ko lākou mau waiwai kūikawā e like me ka elasticity, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa kemika. Ma waena o kēia mau mea, ʻo ka laholio fluorine (FKM) a me ka laholio perfluoroether (FFKM) e kū nei he mau laholio hana kiʻekiʻe, kaulana no ko lākou kūpaʻa kemika kiʻekiʻe a me ke kūpaʻa wela kiʻekiʻe. Ke ʻimi nei kēia loiloi 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 kuleana ma nā ʻoihana pili.
Nā ʻokoʻa kumu ma waena o ka Fluorine Rubber (FKM) a me ka Perfluoroether Rubber (FFKM)
ʻAno Kemika
ʻO ka ʻokoʻa nui ma waena o FKM a me FFKM aia i ko lākou mau ʻano kemika. ʻO FKM kahi polymer fluorinated hapa me nā pilina kalapona-kalapona (CC) i loko o kona kaulahao nui, ʻoiai ʻo FFKM kahi polymer fluorinated piha me kahi ʻano kalapona-oxygen-kalapona (COC), i hoʻopili ʻia e nā ʻātoma oxygen (O). ʻOi aku ka maikaʻi o kēia ʻokoʻa hoʻonohonoho ʻana o FFKM i ke kūpaʻa kemika a me ke kiʻekiʻe o ka mahana i hoʻohālikelike ʻia me FKM.
Ke kū'ē kemika
ʻO ke kaulahao nui o FFKM, me ka ʻole o nā pilina kalapona-kalapona, hāʻawi i ka pale ʻana i nā mea kemika. E like me ka mea i hōʻike ʻia ma ke kiʻi e hele pū ana, ʻo ka ikehu pilina o nā pilina kalapona-hauwai ka mea haʻahaʻa loa (ma kahi o 335 kJ/mol), hiki ke hoʻolilo iā FKM i mea liʻiliʻi i ka maikaʻi i nā oxidants ikaika a me nā solvents polar i hoʻohālikelike ʻia me FFKM. Kūpaʻa ʻo FFKM i nā mea kemika āpau i ʻike ʻia, me nā waikawa ikaika, nā kumu, nā solvents organik, a me nā oxidants.
Ke kū'ē ʻana i ka mahana kiʻekiʻe
ʻOi aku ka maikaʻi o FFKM i ke kūpaʻa ʻana i ka mahana kiʻekiʻe. ʻOiai ʻo ka mahana hana mau o FKM maʻamau mai 200-250°C, hiki i ka FFKM ke kū i nā mahana a hiki i 260-300°C. ʻO kēia kūpaʻa wela kiʻekiʻe e kūpono loa ai ʻo FFKM no nā noi ma nā wahi koʻikoʻi.
Nā Kahua Noi
ʻO ka laholio Fluorine (FKM)
Hoʻohana nui ʻia ʻo FKM ma nā ʻano like ʻole ma muli o kona kūpaʻa kemika maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe:
- ʻOihana Kaʻa: Hoʻohana ʻia ʻo FKM i ka hana ʻana i nā sila, nā sila aila, nā O-ring, a me nā mea hou aku, ʻoi aku hoʻi i nā mīkini a me nā ʻōnaehana hoʻoili.
- ʻOihana Kemika: Hoʻohana ʻia ʻo FKM no nā sila i loko o nā paipu, nā kiwikā, nā pamu, a me nā lako ʻē aʻe e pale aku ai i ka liki ʻana o ka pāpaho kemika.
- ʻOihana Uila: Hoʻohana ʻia no nā papa insulation i loko o nā uea a me nā kaula, ʻoi aku hoʻi i nā wahi wela kiʻekiʻe a me nā wahi ʻino kemika.
ʻO ka laholio Perfluoroether (FFKM)
Hoʻohana ʻia ka FFKM ma nā kahua e koi ana i ke kūpaʻa kemika a me ke kūpaʻa wela kiʻekiʻe:
- Aerospace: Hoʻohana ʻia ʻo FFKM no nā sila i loko o nā mokulele a me nā moku mokulele e hoʻomanawanui i nā mahana koʻikoʻi a me nā wahi kemika.
- ʻOihana Semiconductor: Hoʻohana ʻia no nā sila i nā lako hana semiconductor e pale aku i ka leakage kinoea kemika.
- ʻOihana Petrochemical: Hoʻohana ʻia ʻo FFKM no nā sila i nā lako wela kiʻekiʻe a me ke kaomi kiʻekiʻe i nā hale hoʻomaʻemaʻe aila a me nā mea kanu kemika.
Kumukūʻai a me ke kumukūʻai
ʻO ke kumukūʻai hana kiʻekiʻe o FFKM ka hopena i ke kumukūʻai mākeke kiʻekiʻe loa i hoʻohālikelike ʻia me FKM. ʻO ka paʻakikī o nā mea maka a me ke kaʻina hana o FFKM e hoʻonui i kāna kumukūʻai. Eia nō naʻe, no ka hana maikaʻi loa o FFKM i nā wahi koʻikoʻi, kūpono kona kumukūʻai kiʻekiʻe i kekahi mau noi.
Palapala a me ka Hana ʻana
ʻO ka laholio Fluorine (FKM)
Hoʻolako pinepine ʻia ʻo FKM ma ke ʻano he laholio paʻa, laholio hui ʻia, a i ʻole nā ʻāpana i hana mua ʻia. ʻO kāna mau ʻano hana e pili ana i ka hoʻoheheʻe ʻana i ka compression, extrusion, a me ka hoʻoheheʻe ʻana i ka injection. Pono ʻo FKM i nā lako hana kūikawā a me nā palena hana ma muli o kona mahana hana kiʻekiʻe.
ʻO ka laholio Perfluoroether (FFKM)
Hoʻolako ʻia ʻo FFKM ma ke ʻano o ka laholio paʻa, ka laholio hui ʻia, a i ʻole nā ʻāpana i hana mua ʻia. ʻO kona kūpaʻa wela kiʻekiʻe e koi ana i nā mahana hana kiʻekiʻe a me nā pono lako a me nā kaʻina hana ʻoi aku ka paʻakikī.
Hoʻohālikelike Hana
Ke kū'ē kemika
ʻOi aku ka maikaʻi o ke kūpaʻa kemika o FFKM ma mua o FKM. Kūpaʻa ka FFKM i nā mea kemika āpau i ʻike ʻia, me nā waikawa ikaika, nā kumu, nā mea hoʻoheheʻe organik, a me nā mea hoʻomake. ʻOiai hāʻawi pū ʻo FKM i ke kūpaʻa kemika maikaʻi, ʻaʻole ia he maikaʻi loa i kekahi mau mea hoʻomake ikaika a me nā mea hoʻoheheʻe polar i hoʻohālikelike ʻia me FFKM.
Ke kū'ē ʻana i ka mahana kiʻekiʻe
ʻOi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe o FFKM ma mua o FKM. ʻO ka mahana hana mau o FKM maʻamau he 200-250°C, ʻoiai hiki i ka FFKM ke piʻi i 260-300°C. ʻO kēia kūpaʻa wela kiʻekiʻe e hoʻohana nui ai i ka FFKM ma nā wahi koʻikoʻi.
Hana Mīkini
Loaʻa iā FKM a me FFKM nā waiwai mechanical maikaʻi loa, me ke elasticity kiʻekiʻe, ke kūpaʻa ʻana i ka ʻaʻahu, a me ke kūpaʻa ʻana i ka haehae. Eia nō naʻe, ʻoi aku ka paʻa o nā waiwai mechanical o FFKM i nā mahana kiʻekiʻe, e ʻoi aku ka hilinaʻi i nā noi wela kiʻekiʻe.
Nā Manaʻolana Kūʻai
Me ka holomua mau o ka ʻenehana ʻoihana, ke piʻi nei ke koi no nā mea laholio hana kiʻekiʻe. Loaʻa iā FKM lāua ʻo FFKM nā manaʻolana noi ākea ma nā ʻano like ʻole ma muli o kā lāua hana maikaʻi loa:
- ʻOihana Kaʻa: Ke hoʻonui nei ka hoʻomohala ʻana o nā kaʻa ikehu hou i ke koi no nā sila kūpaʻa i ka mahana kiʻekiʻe a me ka pale ʻana i ka palaho kemika, e hoʻonui hou ana i ka noi o FKM a me FFKM.
- ʻOihana Kemika: ʻO ka hoʻololi ʻana a me ka paʻakikī o nā huahana kemika e hoʻonui nei i ke koi no nā sila kūpaʻa kemika, e hoʻonui hou ana i ka noi o FKM a me FFKM.
- ʻOihana Uila: ʻO ka hoʻoliʻiliʻi ʻana a me ka hana kiʻekiʻe o nā mea uila e hoʻonui nei i ke koi no nā mea hoʻokaʻawale i kū i nā mahana kiʻekiʻe a me ka pala kemika, e hoʻonui hou ana i ka noi o FKM a me FFKM.
Hopena
ʻO ka ʻōpala fluorine (FKM) a me ka ʻōpala perfluoroether (FFKM), ma ke ʻano he mau ʻelele o nā ʻōpala hana kiʻekiʻe, he mau manaʻolana ākea ko lākou no ka hoʻohana ʻana ma nā ʻano like ʻole ma muli o ko lākou kūpaʻa kemika maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe. ʻOiai he pipiʻi ke kumukūʻai o FFKM, ʻo kāna hana koʻikoʻi i nā wahi koʻikoʻi e hāʻawi iā ia i kahi pono hiki ʻole ke hoʻololi ʻia i kekahi mau noi. Me ka holomua mau o ka ʻenehana ʻoihana, e hoʻomau ka piʻi ʻana o ke koi no nā mea ʻōpala hana kiʻekiʻe, a ākea nā manaʻolana mākeke no FKM a me FFKM.
