Hoʻopuka huahana a me ka hoʻohana ʻana i ka carbide silika ʻeleʻele
Kāpena silika ʻeleʻele(i hoʻopau ʻia e like me ka ʻeleʻele silicon carbide) he mea hana ʻole metala ʻole i hana ʻia me ke one quartz a me ka petroleum coke ma ke ʻano he kumu nui a hoʻoheheʻe ʻia i ka wela kiʻekiʻe i loko o kahi umu kūʻē. He ʻeleʻele-hina a ʻeleʻele paha kona helehelena, ʻo ka paʻakikī kiʻekiʻe loa, ka conductivity thermal maikaʻi a me ke kūpaʻa kemika. He mea ʻoihana maikaʻi loa ia a ua hoʻohana nui ʻia i nā abrasives, refractory material, metallurgy, ceramics, electronics a me nā māla ʻē aʻe.
Ⅰ. Nā hiʻohiʻona hana o ka carbide silikona ʻeleʻele
Ka Mohs paakiki okalapona kalapona ʻeleʻeleʻO ke kiʻekiʻe e like me 9.2, ʻelua wale nō i ka daimana a me ka cubic boron nitride, a he ikaika loa kona pale ʻana a me ka hopena. Ma kahi o 2700 ° C kona helu hoʻoheheʻe ʻana, a hiki iā ia ke mālama i ka paʻa o ke kūkulu ʻana i nā wahi wela kiʻekiʻe a ʻaʻole maʻalahi ka decompose a deform. Eia kekahi, loaʻa iā ia ka conductivity thermal maikaʻi a me ka hoʻonui haʻahaʻa haʻahaʻa haʻahaʻa, a ke hōʻike mau nei i ke kūpaʻa haʻalulu maikaʻi loa ma lalo o ke kiʻekiʻe wela a me nā kūlana kiʻekiʻe.
Ma ke ʻano o nā waiwai kemika, ʻeleʻele silicon carbide he pale corrosion maikaʻi i nā waikawa a me nā alkalis, a kūpono loa ia no ka hoʻohana ʻana i nā ʻoihana i nā wahi paʻakikī. ʻO kona conductivity kiʻekiʻe e hana ia i mea ʻokoʻa no kekahi mau mea hoʻomehana uila a me nā māla semiconductor.
Ⅱ. Nā ʻano huahana nui a me nā kikoʻī
Hiki ke hana ʻia ka carbide silicon ʻeleʻele i nā ʻano like ʻole e like me ka nui o nā ʻāpana like ʻole a me ka hoʻohana ʻana:
Mea poloka: nā kristal nui ma hope o ka hoʻoheheʻe ʻana, hoʻohana pinepine ʻia no ka hoʻoponopono hou ʻana a i ʻole nā mea hoʻohui metala;
ʻO ke one nui (F sand/P sand): hoʻohana ʻia e hana i nā huila wili, sandblasting abrasives, sandpaper, etc.;
ʻO ka pauka Micro (W, D series): hoʻohana ʻia no ka wili ultra-precision, polishing, sintering ceramic, etc.;
Nano-level micro powder: hoʻohana ʻia no nā seramika uila kiʻekiʻe, thermal conductive composite material, etc.
ʻO ka nui o ka nui mai ka F16 a hiki i ka F1200, a hiki i ka nui o ka pauka micro hiki ke hiki i ke kiʻekiʻe nanometer, hiki ke hoʻopili ʻia e like me nā koi ʻenehana o nā kahua noi like ʻole.
Ⅲ. Nā wahi noi nui o ka carbide silika ʻeleʻele
1. Nā mea hana abrasive a me ka wili
ʻO Abrasive nā wahi hoʻohana maʻamau a hoʻohana nui ʻia o ka carbide silicon ʻeleʻele. ʻO ka hoʻohana ʻana i kona ʻano paʻakikī kiʻekiʻe a me ka hoʻomaʻamaʻa ponoʻī, hiki ke hoʻohana ʻia ka silicon carbide ʻeleʻele no ka hana ʻana i nā huahana abrasive like ʻole, e like me ka wili huila, ka ʻoki ʻana i nā discs, ka sandpaper, nā poʻo wili, nā paʻi wili, a me nā mea ʻē aʻe, kūpono no ka wili ʻana a me ka hana ʻana i nā mea e like me ka hao hao, ke kila, nā metala non-ferrous, keramika, aniani, quartz.
ʻO kāna mau mea maikaʻi ʻo ka wikiwiki wili ʻana, ʻaʻole maʻalahi ke clog, a me ka hana kiʻekiʻe. Hoʻohana nui ʻia ia i ka hana metala, ka hana ʻana i nā mīkini, nā hale hoʻonaninani a me nā ʻoihana ʻē aʻe.
2. ʻO nā mea hoʻopaʻa
Ma muli o kona kūpaʻa wela kiʻekiʻe a me ke kūpaʻa corrosion, hoʻohana nui ʻia ka carbide silicon ʻeleʻele i ke kahua o nā mea refractory kiʻekiʻe. Hiki ke hana ʻia i loko o ka silicon carbide bricks, furnace linings, crucibles, thermocouple protection tubes, kiln tools, nozzles, tuyere bricks, etc., a hoʻohana nui ʻia i nā ʻoihana kiʻekiʻe e like me ka metallurgy, non-ferrous metala, uila, aniani, cement, etc.
Eia kekahi, he mau waiwai antioxidant maikaʻi nā mea silicon carbide i nā ea oxidizing kiʻekiʻe a he kūpono no ka hoʻohana ʻana i nā ʻāpana koʻikoʻi o nā puʻu wela wela, nā umu ahi a me nā mea hana ʻē aʻe.
3. ʻoihana metallurgical
I nā kaʻina hana metallurgical e like me ka hana kila a me ka hoʻolei ʻana, hiki ke hoʻohana ʻia ka carbide silicon ʻeleʻele ma ke ʻano he deoxidizer, mea hoʻomehana a me recarburizer. Ma muli o kona ʻano kalapona kiʻekiʻe a me ka hoʻokuʻu ʻana i ka wela wikiwiki, hiki iā ia ke hoʻomaikaʻi maikaʻi i ka hoʻoheheʻe ʻana a hoʻomaikaʻi i ka maikaʻi o ke kila hoʻoheheʻe. I ka manawa like, hiki iā ia ke hōʻemi i ka ʻike haumia i loko o ke kaʻina hoʻoheheʻe ʻana a pāʻani i kahi hana i ka hoʻomaʻemaʻe ʻana i ke kila hoʻoheheʻe.
Hoʻohui pū kekahi mau wili kila i kahi hapa o ka silicon carbide e hoʻoponopono i ka haku mele i ka hoʻoheheʻe ʻana i ka hao a me ka hao ductile e mālama ai i nā kumukūʻai a hoʻomaikaʻi i ka hana o ka hoʻoheheʻe ʻana.
4. ʻO nā seramika a me nā mea uila
ʻO ka carbide silika ʻeleʻele kekahi mea waiwai nui no nā seramika hana. Hiki ke ho'ohana 'ia no ka ho'omākaukau 'ana i nā ceramics, nā mea 'a'ahu-kū'ele'ele, thermal conductive ceramics, a me nā mea'ē a'e, a he ākea ka mana'o ma ka 'oihana uila, kemika 'oihana, machinery, etc.
Eia kekahi, ua komo mālie ka silicon carbide i ke kahua o nā semiconductors mana a lilo i kumu kumu no nā mea wela kiʻekiʻe a kiʻekiʻe. ʻOiai ʻoi aku ka haʻahaʻa o ka maʻemaʻe o ka carbide silicon ʻeleʻele ma mua o ka carbide silika ʻōmaʻomaʻo, hoʻohana pū ʻia ia i kekahi mau huahana uila a haʻahaʻa.
5. ʻOihana Photovoltaic a me ka ikehu hou
Hoʻohana nui ʻia ka pauka silicon carbide ʻeleʻele i ka ʻoki ʻana i nā wafer silika i ka ʻoihana photovoltaic. E like me ka abrasive i loko o ka daimana uea oki kaʻina hana, ia i na pono o ka paakiki kiʻekiʻe, ikaikaʻoki ʻokiikaika, poho haʻahaʻa, a me ka ʻoki ʻoki maʻemaʻe, e kōkua ana i ka hoʻomaikaʻi ʻana i ka maikaʻi o ka ʻoki ʻana a me ka loaʻa ʻana o nā wafer silika a hoʻemi i ka nui o ka poho wafer a me nā kumukūʻai hana.
Me ka hoʻomau mau ʻana o ka ikehu hou a me nā ʻenehana waiwai hou, ke kūkulu ʻia nei ka silicon carbide no nā māla e kū mai ana e like me ka lithium battery negative electrode additives a me nā mea lawe membrane ceramic.
Ⅳ. Hōʻuluʻulu manaʻo a me Outlook
He mea hiki ʻole ke hoʻololi ʻia ka carbide silicon ʻeleʻele i nā ʻano ʻoihana he nui me kāna mau mea mechanical, thermal a me kemika. Me ka holomua mau o ka ʻenehana hana, ka mana o ka nui o nā huahana, ka hoʻomaʻemaʻe maʻemaʻe a me ka hoʻonui mau ʻana o nā kahua noi, ke ulu nei ka carbide silicon ʻeleʻele i ka hana kiʻekiʻe a me ka pololei.
I ka wā e hiki mai ana, me ka piʻi wikiwiki o nā ʻoihana e like me ka ikehu hou, nā seramika uila, kiʻekiʻewili ana a me ka hana akamai, ʻeleʻele silicon carbide e pāʻani i kahi kūlana koʻikoʻi ma ke kahua o ka hana kiʻekiʻe a lilo i mea koʻikoʻi o ka ʻōnaehana ʻenehana waiwai holomua.
