I kēia lā e ulu wikiwiki nei ka ʻenehana, ʻo ka puka mau ʻana o nā mea hou i lawe mai i nā loli kipi i nā ʻoihana like ʻole.Silicon carbide ʻoihana seramika, 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 koʻikoʻi e hoʻokele i ka holomua ma nā ʻoihana like ʻole.
1, He aha ka silicon carbide industrial ceramic?
ʻO nā mea ʻenehana silicon carbide, ma nā ʻōlelo maʻalahi, he mau mea seramika i haku mua ʻia me ka silicon carbide (SiC). ʻO ka Silicon carbide ponoʻī he pūhui i hoʻokumu ʻia e ka hopena o ke silikoni a me ke kalapona i nā wela kiʻekiʻe, a ʻo kāna ʻano atomic kū hoʻokahi e hāʻawi i ka waiwai me nā waiwai maikaʻi loa.
Mai kahi hiʻohiʻona microscopic, paʻa ke ʻano aniani o ka silicon carbide, a ʻo nā mea paʻa kemika ma waena o nā atoms he ikaika, e hana ai i ka silicon carbide ceramics i ke kūpaʻa maikaʻi a me ka paʻa. Ke hoʻohālikelike ʻia me nā mea metala kuʻuna, ʻaʻole i haku ʻia nā seramika ʻoihana silicon carbide me nā ʻātoma metala i hoʻopaʻa ʻia e nā paʻa metala; ʻAʻole e like me nā mea polymer organik maʻamau, ʻaʻole ia i haku ʻia me nā kaulahao molekala kūlohelohe. He ʻano hou ia o nā mea non-metallic inorganic i hoʻokumu ʻia e ka sintering silicon carbide pauka ma lalo o ke kiʻekiʻe kiʻekiʻe a me nā kūlana kiʻekiʻe ma o ke kaʻina hana hoʻomākaukau seramika kūikawā.
2、 Ka wehe ʻana i ka hana maikaʻi loa
1. ʻO ka paʻakikī kiʻekiʻe loa, kūʻokoʻa a paʻa
He kiʻekiʻe loa ka paʻakikī o ka silicon carbide industrial ceramics, ʻelua wale nō i ke daimana ma ke ʻano. ʻO kēia hiʻohiʻona he mea maikaʻi loa ia ma ke ʻano o ka pale ʻana i ka lole. E noʻonoʻo i ke kahua o ka hana mīkini, pono e hui pinepine nā mea ʻoki me nā mea metala like ʻole no ka ʻoki ʻana. Inā ʻaʻole lawa ka ʻaʻahu ʻana o ka mea paahana, e pau koke ia a lilo i polu, e pili ana i ka pololei a me ka pono o ka mīkini. ʻO nā mea hana ʻokiʻoki i hana ʻia me ka silicon carbide industrial ceramics, me ko lākou ultra-high hardness, hiki ke mālama i ka ʻoi no ka manawa lōʻihi, e hoʻomaikaʻi nui ana i ka hana ʻana a me ka hōʻemi ʻana i nā kumukūʻai hana.
2. Ke kūpaʻa wela kiʻekiʻe, kūpaʻa a hilinaʻi
ʻO nā seramika ʻoihana Silicon carbide maikaʻi loa ka pale wela kiʻekiʻe. I loko o nā kaiapuni kiʻekiʻe, nui nā mea i hoʻopalupalu ʻia, deformation, a me ka hoʻoheheʻe ʻana, ʻoiai hiki i ka silicon carbide ceramics ke mālama i nā waiwai kino a me nā mea kemika i nā wela nui. Eia kekahi laʻana, i nā kapuahi wela kiʻekiʻe i kaʻoihana metallurgical, pono e hoʻohana i nā mea hiki ke pale i nā wela kiʻekiʻe no ka hanaʻana i nā kapuahi kapuahi, crucibles, a me nā mea'ē aʻe. Hiki i ka silikoni carbide ʻoihana keramika ke hana i kēia hana, e hōʻoiaʻiʻo ana i ka hana maʻamau o ka umu wela kiʻekiʻe a hoʻonui i ke ola lawelawe o nā mea hana.
3. Paʻa kemika maikaʻi
Ke kū nei i nā kemika corrosive e like me nā ʻakika ikaika a i ʻole nā kumu, hiki i ka silicon carbide industrial ceramics ke mālama iā lākou me ka mālie. I ka hana kemika, pono pinepine ka lawelawe ʻana i nā ʻano mea kino kemika nui loa, a ʻo nā ipu a me nā pipeline i hoʻohana ʻia no ka mālama ʻana a me ka lawe ʻana i kēia mau mea maka e koi ai i ke kūpaʻa corrosion kiʻekiʻe loa o nā mea. ʻO nā seramika ʻenehana 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 pipeline, me ka pale ʻana i nā pōʻino palekana e like me nā leaks i kumu ʻia e ka corrosion.
4. ʻOi aku ka wela wela
Loaʻa i nā ʻoihana ʻenehana Silicon carbide i ka conductivity thermal maikaʻi loa a hiki ke hana wikiwiki i ka wela. He mau noi koʻikoʻi kēia hana i nā hiʻohiʻona e koi ana i ka hoʻoheheʻe wela i ka manawa, e like me kekahi mau mea hana wela wela, kahi e hiki ai i ka hōʻiliʻili wela ke hoʻopilikia i ka hana maʻamau. Hiki i nā ʻāpana hoʻoheheʻe wela i hana ʻia me ka silicon carbide industrial ceramics hiki ke hoʻopau koke i ka wela, e hōʻoia i ka hana paʻa o nā mea hana.
3、 Loaʻa nā kahua pili
1. Hana mīkini
I loko o kaʻoihana mechanical manufacturing, silicon carbide industrial ceramics ua hoʻohanaʻia no ka hanaʻana i nā mea likeʻole e like me nā bearings, sealing rings, cutting tools, etc.
2. Ka mining metallurgy
ʻO ke kaiapuni i ke kahua o ka mining metallurgy he paʻakikī pinepine, a ke alo nei nā mea hana i nā hoʻāʻo he nui e like me ka ʻaʻahu, ka wela kiʻekiʻe, a me ka corrosion. Hiki ke hoʻohana ʻia nā seramika ʻoihana carbide silikon, me ko lākou pale ʻana i ka lole kiʻekiʻe loa, no ka hana ʻana i nā papa lining no ka ʻeli ʻana i nā mea hana ʻokiʻoki a me nā ʻāpana pale pale no nā wili metallurgical. I ka wā o ke kaʻina ʻana o ka ʻai, hiki i nā papa lining seramika ke pale aku i ka hopena koʻikoʻi a me ka friction o ka ʻaila, e hoʻolōʻihi i ka pōʻai o nā mea hana; I ke kaʻina hana metallurgical, e kū ana i ka erosion o ka heheʻe wela kiʻekiʻe, hiki i nā ʻāpana seramika silicon carbide ke mālama i ka paʻa, e hōʻoia i ka holomua mau o ka hana metallurgical.
3. ʻOihana desulfurization
I ke kaʻina hana o ka desulfurization ʻoihana, pili nā kinoea corrosive a me nā wai i loaʻa i ka sulfur, kahi e koi ai i ke kūpaʻa corrosion kiʻekiʻe loa o nā mea hana. Ua lilo nā seramika ʻoihana silikoni i mea kūpono no nā lako desulfurization ma muli o ko lākou kūpaʻa kemika maikaʻi loa. No ka laʻana, ua hana ʻia nā nozzles spray, pipelines a me nā mea ʻē aʻe i loko o ka hale kiaʻi desulfurization me ka silicon carbide ceramics, hiki ke pale maikaʻi i ka ʻino o nā ion sulfur, hōʻemi i nā hemahema o nā lako, hōʻoia i ka hana maikaʻi o ka ʻōnaehana desulfurization, a kōkua i nā ʻoihana e hoʻokō i nā kūlana kūlohelohe.
Ke lilo nei ka silikon carbide ʻoihana seramika i mea waiwai nui a koʻikoʻi i ka ʻoihana hou ma muli o kā lākou mau waiwai kūʻokoʻa a me nā kahua noi ākea. Ke manaʻoʻiʻo nei au i ka wā e hiki mai ana, e hōʻike ana ia i ka mana nui i nā kula hou aʻe a hāʻawi i nā kōkua nui i ka hoʻomohala ʻana i ke kaiāulu kanaka.
