I loko o nā hiʻohiʻona hana ʻoihana he nui, he mea maʻamau nā wahi wela kiʻekiʻe akā he paʻakikī loa. Inā paha he lapalapa ahi e ʻā ana i ka wā o ka hoʻoheheʻe ʻana i ke kila, nā umu wela kiʻekiʻe i ka hana aniani, a i ʻole nā mea hana wela kiʻekiʻe i ka hana kemika, ua kau ʻia nā koi koʻikoʻi ma ke kūpaʻa wela kiʻekiʻe o nā mea. Aia kekahi mea e pāʻani ana i kahi kuleana koʻikoʻi i kēia mau kahua wela kiʻekiʻe a ʻaʻole hiki ke hoʻowahāwahā ʻia, ʻo ia hoʻinā poloka pale wela silicon carbide.
ʻO ka Silicon carbide, mai kahi kuanaʻike o ka hoʻohuihui kemika, he hui i haku ʻia me ʻelua mau mea: silicon (Si) a me carbon (C). ʻOiai ka loaʻa ʻana o ka huaʻōlelo 'silicon' ma kona inoa, ʻokoʻa loa kona helehelena mai nā mea silicon a mākou e ʻike ai i ko mākou ola o kēlā me kēia lā. ʻIke pinepine ʻia ka Silicon carbide ma ke ʻano he mau kristal ʻeleʻele a ʻōmaʻomaʻo paha, me kahi ʻano paʻakikī a me ka paʻakikī kiʻekiʻe. Ke hoʻohana ʻia e kahakaha i ke aniani, e waiho maʻalahi ia i nā māka ma ke aniani, e like me ka ʻoki ʻana i ka pata me ka pahi liʻiliʻi.
ʻO ke kumu e kū ai nā poloka pale wela silicon carbide i nā wahi wela kiʻekiʻe ma muli o kā lākou mau waiwai maikaʻi loa. ʻO ka mea mua, he kūpaʻa wela kiʻekiʻe loa ia, me kahi kiko heheʻe kiʻekiʻe loa, ʻo ia hoʻi hiki ke noho paʻa i nā wahi ʻoihana wela kiʻekiʻe a ʻaʻole e palupalu maʻalahi, hoʻololi, a heheʻe paha. Ke piʻi aʻe ka mahana i loko o ka umu hoʻoheheʻe kila, ua hoʻomaka paha nā mea ʻē aʻe e "halihali i ke kaumaha", akā hiki i nā poloka pale wela silicon carbide ke "noho mālie" a hāpai mau i ke kuleana o ka pale ʻana i ke kino umu a me ka mālama ʻana i ka hana ʻana.
He maikaʻi loa nō hoʻi ke kūpaʻa kemika o nā poloka pale wela silicon carbide. Loaʻa iā ia ke kūpaʻa maikaʻi i nā ʻano kemika like ʻole, a he paʻakikī no nā waikawa corrosive ikaika a i ʻole nā mea alkaline e hōʻino iā ia. I ka hana kemika, loaʻa pinepine nā kemika corrosive like ʻole. ʻO ka hoʻohana ʻana i nā poloka pale wela silicon carbide ma ke ʻano he uhi o nā lako hana hiki ke pale pono i nā lako mai ka palaho ʻana, hoʻolōʻihi i ke ola lawelawe o nā lako, a hoʻemi i nā kumukūʻai hana.
Ma waho aʻe o nā waiwai i luna, loaʻa i nā poloka pale wela silicon carbide ke kūpaʻa maikaʻi i ka ʻaʻahu a me ka ikaika kiʻekiʻe. I kekahi mau wahi wela kiʻekiʻe me ka ʻino ʻana o nā mea, e like me nā mea hoʻokaʻawale cyclone a me nā umu calcination i nā hale hana sima, hiki i nā poloka pale wela silicon carbide ke hōʻemi i nā pohō i hoʻokumu ʻia e ka friction mea ma muli o ko lākou mau waiwai pale ʻaʻahu, e hōʻoiaʻiʻo ana i ka hana maʻamau o nā lako. ʻO kona ikaika kiʻekiʻe e hiki ai iā ia ke kū i kekahi mau kaomi a me nā ikaika hopena, e mālama ana i ka pono o ke kūkulu ʻana i nā wahi ʻoihana paʻakikī.
Hoʻohana nui ʻia nā poloka pale wela o Silicon carbide ma ke kahua ʻoihana. Ma ka ʻoihana kila, hoʻohana nui ʻia ia i nā lako e like me nā umu pahū a me nā kapuahi pahū wela. I loko o ka umu pahū, he kiʻekiʻe loa nā koi o ka hao hoʻoheheʻe wela kiʻekiʻe a me ka slag no nā mea uhi. ʻO nā poloka pale wela o Silicon carbide, me ko lākou pale wela kiʻekiʻe a me ke kūpaʻa ʻana i ka erosion, ua lilo i koho kūpono no nā mea uhi, e hoʻolōʻihi pono ana i ke ola lawelawe o ka umu pahū a hoʻomaikaʻi i ka pono a me ka maikaʻi o ka hana kila. I loko o ka umu pahū wela, lawelawe nā poloka pale wela o Silicon carbide ma ke ʻano he mau kino mālama wela, hiki ke mālama pono a hoʻokuʻu i ka wela, e hāʻawi ana i ka ea wela wela kiʻekiʻe no ka umu pahū a hoʻomaikaʻi i ka pono o ka hoʻohana ʻana i ka ikehu.
I loko o ka ʻoihana hoʻoheheʻe metala non-ferrous, e like me ke kaʻina hana hoʻoheheʻe o ka alumini, ke keleawe a me nā metala ʻē aʻe, he mea pono nō hoʻi nā poloka pale wela silicon carbide. He kiʻekiʻe iki ka mahana hoʻoheheʻe o kēia mau metala, a ua hoʻopuka ʻia nā ʻano kinoea ʻino a me nā slag i ka wā o ke kaʻina hana hoʻoheheʻe. Hiki i nā poloka pale wela silicon carbide ke hoʻololi maikaʻi i ia mau ʻano ʻino, pale i nā lako umu, a hōʻoia i ka hoʻoheheʻe maʻalahi ʻana o nā metala non-ferrous.
He mea nui nō hoʻi nā noi o nā poloka pale wela o ka silicon carbide i nā ʻoihana keramika a me ke aniani. Pono e hoʻokō ʻia ke kuni ʻana i ka seramika i loko o nā umu wela kiʻekiʻe. ʻO nā umu i hana ʻia me nā poloka silicon carbide pale wela, e like me nā papa hale hoʻolei, nā pahu, a me nā mea ʻē aʻe, ʻaʻole hiki ke kū i nā mahana kiʻekiʻe wale nō, akā e hōʻoia pū i ke kūpaʻa a me ke kūlike o nā huahana seramika i ka wā o ke kaʻina hana kuni ʻana, kahi e kōkua ai i ka hoʻomaikaʻi ʻana i ka maikaʻi o nā huahana seramika. I loko o nā umu hoʻoheheʻe aniani, hoʻohana ʻia nā poloka pale wela o ka silicon carbide no ka uhi ʻana a me nā keʻena mālama wela, hiki ke kū i ka ʻino ʻana o ka mahana kiʻekiʻe a me ka holoi ʻana o ka wai aniani, me ka hoʻomaikaʻi ʻana i ka pono wela o ka umu a me ka hoʻemi ʻana i ka hoʻohana ʻana i ka ikehu.
Me ka holomua mau o ka ʻenehana a me ka hoʻomohala mau ʻana o ka ʻoihana, e ʻoi aku ka laulā o nā manaʻolana noi o nā poloka pale wela silicon carbide. Ma kekahi ʻaoʻao, ke ʻimi mau nei nā mea noiʻi i nā kaʻina hana hoʻomākaukau hou a me nā ʻenehana e hoʻomaikaʻi hou aku i ka hana o nā poloka pale wela silicon carbide a hoʻemi i nā kumukūʻai hana. No ka laʻana, ma ka hoʻohana ʻana i kahi kaʻina hana sintering hou, hiki ke hoʻonui ʻia ka nui a me ke ʻano o nā poloka pale wela silicon carbide, a laila e hoʻomaikaʻi ana i kā lākou hana holoʻokoʻa. Ma kekahi ʻaoʻao, me ka piʻi wikiwiki ʻana o nā ʻoihana e kū mai ana e like me ka ikehu hou a me ka aerospace, ke piʻi nei hoʻi ke koi no nā mea pale wela kiʻekiʻe, a manaʻo ʻia e pāʻani nui nā poloka pale wela silicon carbide i kēia mau kahua.
