he aha nā ipu hoʻoheheʻe i hoʻohana ʻia no

I loko o nā noi ʻoihana wela kiʻekiʻe he nui, he kuleana koʻikoʻi nā ipu hoʻoheheʻe ma ke ʻano he mau ipu koʻikoʻi no ka mālama ʻana a me ka hoʻomehana ʻana i nā mea.Nā ipu hoʻoheheʻe keramika silikona, me kā lākou hana maikaʻi loa, e lilo mālie nei i koho makemake ʻia ma nā ʻoihana like ʻole.
1, He aha ka ipu hoʻoheheʻe keramika silicon carbide
ʻO ka ipu hoʻoheheʻe keramika Silicon carbide kahi ipu hohonu i hana ʻia me ka mea keramika silicon carbide. He hui ʻo Silicon carbide me nā pilina covalent ikaika, a ʻo kona hoʻopaʻa kemika kū hoʻokahi e hāʻawi i nā ipu hoʻoheheʻe me nā waiwai maikaʻi he nui. Ke hoʻohālikelike ʻia me nā kīʻaha aniani maʻamau, hiki i nā ipu hoʻoheheʻe keramika silicon carbide ke kū i nā mahana kiʻekiʻe a he mau mea hana kūpono no nā hana hoʻomehana wela kiʻekiʻe.
2, Nā Pono o nā ipu hoʻoheheʻe keramika Silicon Carbide
1. Kū'ē maika'i loa i ka mahana ki'eki'e: Hiki i nā ipu ho'ohehe'e keramika Silicon carbide ke kū i nā mahana a hiki i kahi o 1350 ℃. E emi nui ana ka ikaika o nā mea keramika ma'amau i ka 1200 ℃, a hiki nō ke mālama 'ia ka ikaika kūlou o ka silicon carbide i kahi ki'eki'e ma 1350 ℃. 'O kēia 'ano e hana maika'i ai i ka ho'ohehe'e 'ana i ka mahana ki'eki'e, ke kuni 'ana a me nā hana 'ē a'e, e hā'awi ana i kahi kūlana pa'a no nā mea a me ka hō'oia 'ana i ka holomua ma'alahi o ke ka'ina hana.
2. Kū'ē maika'i i ka oxidation: Hiki i nā ipu ho'ohehe'e keramika Silicon carbide ke mālama i ke kū'ē maika'i i ka oxidation i nā wahi mahana ki'eki'e. Me ka ho'onui'ia o ka nui o ka silicon carbide, ho'omaika'i hou'ia ke kū'ē oxidation o ka ipu ho'ohehe'e. 'O ke'ano kēia,'a'ole ia e ma'alahi ke oxidize a hō'ino'ia i ka wā lō'ihi o ka ho'ohana'ana i ka mahana ki'eki'e, e ho'olō'ihi nui ana i kona ola lawelawe, e ho'emi ana i ke alapine o ka ho'ololi'ana i ka ipu ho'ohehe'e, a e ho'oha'aha'a ana i nā kumukū'ai hana.
3. Paʻa kemika maikaʻi loa: ʻOi aku ka paʻa o nā keramika carbide Silicon i nā hopena ʻino. I nā ʻoihana e pili ana i nā mea kemika like ʻole e like me ka metallurgy a me ka ʻenekinia kemika, ʻaʻole ia e pane me nā mea kemika e pili ana, no laila e hōʻoiaʻiʻo ana i ka maʻemaʻe o nā mea i hoʻoheheʻe ʻia a i ʻole i hana ʻia, e pale ana i ka hoʻokomo ʻana o nā haumia, a hoʻomaikaʻi i ka maikaʻi o ka huahana.
4. Paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu: He paʻakikī kiʻekiʻe ko Silicon carbide, ʻo ia ka mea e loaʻa ai ke kūpaʻa maikaʻi o ka ipu hoʻoheheʻe i hana ʻia a hiki ke kū i ke ʻaʻahu kino i nā mahana kiʻekiʻe. I ka wā o ka hoʻohana lōʻihi, hiki iā ia ke mālama i ke kūpaʻa o kona ʻano a ʻaʻole maʻalahi ke ʻaʻahu ʻia a hoʻololi ʻia paha, e hōʻoia hou ana i kona pono a me ke ola lawelawe.

3, Nā kahua noi o nā ipu hoʻoheheʻe keramika silicon carbide
1. ʻOihana Metallurgical: Inā paha he hoʻomaʻemaʻe ʻana i nā metala ferrous e like me ke kila, a i ʻole ka hoʻoheheʻe ʻana o nā metala non-ferrous a me kā lākou mau mea hoʻohuihui e like me ke keleawe, alumini, zinc, a me nā mea ʻē aʻe, he kuleana koʻikoʻi nā ipu hoʻoheheʻe keramika silicon carbide. Hiki iā ia ke kū i ka ʻino ʻana o ka wai metala wela kiʻekiʻe, e hōʻoiaʻiʻo ana i ka holomua mālie o ke kaʻina hana hoʻoheheʻe metala, me ka hōʻoiaʻiʻo ʻana i ka maʻemaʻe o ka metala a me ka hoʻomaikaʻi ʻana i ka maikaʻi o nā huahana metala.
2. ʻOihana kemika: hoʻohana ʻia no nā hopena kemika wela kiʻekiʻe a me ka mālama ʻana i nā mea ʻino. Ma muli o kona kūpaʻa kemika maikaʻi loa a me ke kūpaʻa wela kiʻekiʻe, hiki iā ia ke hana paʻa i ke alo o nā mea kemika like ʻole a me nā wahi hopena wela kiʻekiʻe, e hōʻoiaʻiʻo ana i ka holomua mālie o nā hopena kemika me ka pale ʻana i ka ipu hoʻoheheʻe ponoʻī mai ka palaho ʻana a me ka hōʻino ʻia.
3. Umu ʻoihana: hoʻohana ʻia ma ke ʻano he ipu hoʻomehana no ke kuni ʻana i nā mea ʻoihana like ʻole, e like me nā piliki pale ahi. Ma ka hoʻohana ʻana i kona conductivity thermal maikaʻi a me ke kūpaʻa wela kiʻekiʻe, hiki iā ia ke hoʻoili wikiwiki a like i ka wela, hōʻoia i ka maikaʻi o ke kuni ʻana i nā mea, a hoʻomaikaʻi i ka pono o ka hoʻohana ʻana i ka ikehu.
ʻO nā ipu hoʻoheheʻe keramika Silicon carbide, me kahi moʻo o nā pono e like me ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa oxidation, ke kūpaʻa ʻaʻahu, a me ke kūpaʻa kemika, ua hōʻike i ka waiwai noi nui ma nā ʻoihana he nui a he mau ipu kūpono ia ma ke kahua ʻoihana wela kiʻekiʻe. Me ka holomua mau a me ka hana hou o ka ʻenehana, ke manaʻoʻiʻo nei mākou e hoʻopili ʻia nā ipu hoʻoheheʻe keramika silicon carbide ma nā kahua hou aʻe a hāʻawi i ke kākoʻo ikaika no ka hoʻomohala ʻana o nā ʻoihana like ʻole.
