I ka ʻenehana e ulu wikiwiki nei i kēia lā, ʻo ka puka mau ʻana mai o nā mea hou ua lawe mai i nā loli kipi i nā ʻoihana like ʻole.Nā keramika ʻoihana Silicon carbide, ma ke ʻano he mea hana kiʻekiʻe, ke puka mālie nei i ka ʻoihana hou. Me kā lākou hana maikaʻi loa a me ka laulā o nā noi, ua lilo lākou i mea nui e hoʻokele ana i ka holomua ma nā ʻoihana like ʻole.
1, He aha ka silicon carbide industrial ceramic?
ʻO nā keramika ʻoihana Silicon carbide, ma nā huaʻōlelo maʻalahi, he mau mea keramika i haku nui ʻia me ka silicon carbide (SiC). ʻO Silicon carbide ponoʻī kahi hui i hoʻokumu ʻia e ka hopena o ka silicon a me ke kalapona ma nā mahana kiʻekiʻe, a ʻo kona ʻano atomika kū hoʻokahi e hāʻawi i ka mea me nā waiwai maikaʻi loa he nui.
Mai kahi hiʻohiʻona microscopic, ua paʻa ke ʻano kristal o ka silicon carbide, a ikaika nā pilina kemika ma waena o nā ʻātoma, ʻo ia ka mea e loaʻa ai ke kūpaʻa a me ka paʻa o nā keramika silicon carbide. Ke hoʻohālikelike ʻia me nā mea metala kuʻuna, ʻaʻole i hana ʻia nā keramika ʻoihana silicon carbide me nā ʻātoma metala i hoʻopaʻa ʻia e nā pilina metala; ʻAʻole like me nā mea polymer organik maʻamau, ʻaʻole ia i hana ʻia me nā kaulahao molekala organik i hana hou ʻia. He ʻano hou ia o ka mea non-metallic inorganic i hoʻokumu ʻia e ka sintering silicon carbide powder ma lalo o ke kūlana wela kiʻekiʻe a me ke kaomi kiʻekiʻe ma o kahi kaʻina hana hoʻomākaukau keramika kūikawā.
2. Ke hōʻike nei i ka hana kupaianaha
1. ʻO ka paʻakikī kiʻekiʻe loa, kūpaʻa i ke kapa a me ke kapa
He kiʻekiʻe loa ka paʻakikī o nā keramika ʻoihana silicon carbide, ʻo ka lua wale nō ma ke ʻano he daimana. ʻO kēia ʻano e hoʻolilo iā ia i mea maikaʻi loa ma ke ʻano o ke kūpaʻa ʻana i ka ʻaʻahu. E noʻonoʻo i ke kahua o ka hana mīkini, pono nā mea ʻokiʻoki e hoʻopili pinepine me nā mea metala like ʻole no ka ʻokiʻoki. Inā ʻaʻole lawa ka kūpaʻa o ka mea hana, e pau koke ia a lilo i mea palaualelo, e hoʻopilikia ana i ka pololei o ka mīkini a me ka pono. Hiki i nā mea ʻokiʻoki i hana ʻia me nā keramika ʻoihana silicon carbide, me ko lākou paʻakikī kiʻekiʻe loa, ke mālama i ka ʻoi no ka manawa lōʻihi, e hoʻomaikaʻi nui ana i ka pono o ka hana ʻana a me ka hoʻemi ʻana i nā kumukūʻai hana.
2. Ke kūpaʻa wela kiʻekiʻe, paʻa a hilinaʻi hoʻi
He kūpaʻa maikaʻi loa nā keramika ʻoihana Silicon carbide i ke ana wela kiʻekiʻe. I nā wahi wela kiʻekiʻe, nui nā mea e palupalu, hoʻololi ʻia, a hiki i ka heheʻe ʻana, ʻoiai hiki i nā keramika silicon carbide ke mālama i nā waiwai kino a me nā kemika paʻa i nā mahana nui. No ka laʻana, i loko o nā umu wela kiʻekiʻe i ka ʻoihana metallurgical, pono e hoʻohana i nā mea e hiki ke kū i nā mahana kiʻekiʻe e hana i nā uhi umu, nā ipu hoʻoheheʻe, a me nā ʻāpana ʻē aʻe. Hiki i nā keramika ʻoihana Silicon carbide ke hana i kēia hana, e hōʻoiaʻiʻo ana i ka hana maʻamau o ka umu wela kiʻekiʻe a hoʻolōʻihi i ke ola lawelawe o nā lako.
3. Paʻa kemika maikaʻi
Inā paha e kū ana i nā kemika ʻino e like me nā waikawa ikaika a i ʻole nā kumu, hiki i nā keramika ʻoihana silicon carbide ke lawelawe mālie iā lākou. I ka hana kemika, pono pinepine e lawelawe i nā mea maka kemika ʻino like ʻole, a ʻo nā ipu a me nā paipu i hoʻohana ʻia e mālama a lawe i kēia mau mea maka e koi ana i ke kūpaʻa kiʻekiʻe loa o nā mea. ʻO nā keramika ʻoihana silicon carbide, me ko lākou kūpaʻa kemika maikaʻi loa, ua lilo i mea kūpono no ka hana ʻana i kēia mau ipu a me nā paipu, e pale pono ana i nā pōʻino palekana e like me nā leaka i hoʻokumu ʻia e ka ʻino.
4. ʻO ka hoʻokele wela maikaʻi loa
He maikaʻi loa ka hoʻokele wela o nā keramika ʻoihana Silicon carbide a hiki ke hoʻokele koke i ka wela. He mea nui kēia hana i nā hiʻohiʻona e pono ai ka hoʻoheheʻe wela i ka manawa kūpono, e like me kekahi mau lako hana wela kiʻekiʻe, kahi e hiki ai i ka hōʻiliʻili wela nui ke hoʻopilikia i ka hana maʻamau. Hiki i nā ʻāpana hoʻoheheʻe wela i hana ʻia me nā keramika ʻoihana silicon carbide ke hoʻoheheʻe koke i ka wela, e hōʻoiaʻiʻo ana i ka hana paʻa o nā lako.
3, Nā kahua i pili nui ʻia
1. Hana ʻana i nā mīkini
I ka ʻoihana hana mīkini, hoʻohana ʻia nā keramika ʻoihana silicon carbide e hana i nā ʻāpana like ʻole e kūʻē i ke komo ʻana e like me nā bearings, nā apo sila, nā mea ʻokiʻoki, a pēlā aku. Ke hoʻohālikelike ʻia me nā bearings metala kuʻuna, ʻoi aku ka paʻakikī o nā bearings keramika silicon carbide a me ke kūʻē ʻana i ke komo ʻana, a hiki ke hana paʻa ma lalo o nā kūlana paʻakikī e like me ka wikiwiki kiʻekiʻe a me ke kiʻekiʻe o ka mahana, e hoʻomaikaʻi nui ana i ka hana a me ka hilinaʻi o nā lako mīkini.
2. Ke kālai ʻana i ka metallurgy
He ʻino pinepine ke kaiapuni ma ke kahua o ka hana ʻeli ʻana i ka metallurgy, a ke kū nei nā lako i nā hoʻāʻo he nui e like me ke komo ʻana, ke kiʻekiʻe o ka mahana, a me ka pala. Hiki ke hoʻohana ʻia nā keramika ʻoihana Silicon carbide, me ko lākou kūpaʻa ʻana i ke komo ʻana, e hana i nā papa lining no nā lako hana ʻeli ʻana a me nā papa pale ʻaʻahu no nā wili metallurgical. I ka wā o ke kaʻina hana o ka ʻoki ʻana i ka ore, hiki i nā papa lining keramika ke kū'ē i ka hopena koʻikoʻi a me ka friction o ka ore, e hoʻolōʻihi ana i ke kaʻina hana hoʻololi o nā lako; I ke kaʻina hana metallurgical, ke kū nei i ka ʻino o ka heheʻe wela kiʻekiʻe, hiki i nā ʻāpana keramika silicon carbide ke mālama i ke kūpaʻa, e hōʻoia ana i ka holomua mau o ka hana metallurgical.
3. Desulfurization ʻoihana
I ke kaʻina hana o ka desulfurization ʻoihana, pili nā kinoea ʻino a me nā wai i loaʻa ka sulfur, kahi e koi ai i ke kūpaʻa kiʻekiʻe loa o nā lako. Ua lilo nā keramika ʻoihana Silicon carbide i mea kūpono no nā lako desulfurization ma muli o ko lākou kūpaʻa kemika maikaʻi loa. No ka laʻana, ʻo nā nozzles pīpī, nā pipelines a me nā ʻāpana ʻē aʻe i loko o ka hale kiaʻi desulfurization i hana ʻia me nā keramika silicon carbide, hiki ke pale pono i ka pala o nā ion sulfur, hōʻemi i ka hemahema o nā lako, hōʻoia i ka hana pono o ka ʻōnaehana desulfurization, a kōkua i nā ʻoihana e hoʻokō i nā kūlana kaiapuni.
Ke lilo nei nā keramika ʻoihana silikona carbide i mea pono ʻole a koʻikoʻi hoʻi i ka ʻoihana hou ma muli o ko lākou mau waiwai kū hoʻokahi a me nā kahua noi ākea. Ke manaʻoʻiʻo nei au i ka wā e hiki mai ana, e hōʻike ana ia i ka hiki nui ma nā kahua hou aʻe a hāʻawi i nā haʻawina nui i ka hoʻomohala ʻana o ke kaiāulu kanaka.
