ʻAʻole hoʻohana wale ʻia ka silicon carbide sintered kaomi lewa ma ke ʻano he abrasive, akā ʻoi aku ma ke ʻano he mea hou, a hoʻohana nui ʻia i nā huahana ʻenehana kiʻekiʻe, e like me nā keramika i hana ʻia me nā mea silicon carbide. No laila he aha nā pono ʻeono o ka silicon carbide sintering kaomi lewa a me ka hoʻohana ʻana o nā keramika silicon carbide?
ʻEono mau pono o nā mea silicon carbide sintered kaomi lewa:
1. Haʻahaʻa ka nui
ʻOi aku ka haʻahaʻa o ka nui o ka mea silicon carbide ma mua o ka metala, e māmā ai ka hāmeʻa.
2. Ke kūpaʻa ʻana i ka palaho
Loaʻa i ka mea Silicon carbide kahi kiko heheʻe kiʻekiʻe, inertia kemika, a me ke kūpaʻa haʻalulu wela. Hoʻohana ʻia ka silicon carbide i nā abrasives, nā umu seramika, nā blanks silicon carbide, a hiki ke hoʻohana ʻia i ka ʻoihana hoʻoheheʻe a me ka hoʻoheheʻe ʻana me ka umu distillation cylinder vertical, nā piliki, nā lining cell electrolytic alumini, tungsten, umu liʻiliʻi a me nā huahana seramika silicon carbide ʻē aʻe.
3, kiʻekiʻe ka mahana, ua hoʻemi ʻia ke koina hoʻonui wela
Hana ʻia ka mea silicon carbide ma nā mahana kiʻekiʻe. I kekahi mau wahi mahana kiʻekiʻe, pono nā mea e pono ai ka ikaika hana a me ka pololei hana e hiki ai i nā keramika silicon carbide ke hoʻokō. ʻO ke kiʻekiʻe o ka mahana o ka silicon carbide ma kahi o 800, a ʻo ke ana wela o ke kila he 250 wale nō. Ma ka helu ʻana, ʻo ka awelika o ka hoʻonui ʻana o ka thermal o ka silicon carbide ma ka pae o 25 ~ 1400 he 4.10-6 /C. Ua ana ʻia ke coefficient hoʻonui thermal o ka silicon carbide, a hōʻike nā hopena he liʻiliʻi loa ka nui ma mua o nā mea abrasives ʻē aʻe a me nā mea wela kiʻekiʻe. Sintered silicon carbide ma lalo o ke kaomi lewa
4, hoʻokele wela kiʻekiʻe
He kiʻekiʻe ke alakaʻi wela o nā mea silicon carbide, ʻo ia kekahi hiʻohiʻona koʻikoʻi o nā waiwai kino o ka silicon carbide. ʻOi aku ka nui o ke alakaʻi wela o ka silicon carbide ma mua o nā mea refractories a me nā abrades ʻē aʻe, ma kahi o 4 mau manawa o ka corundum. He haʻahaʻa ka coefficient o ka hoʻonui wela o ka Silicon carbide a me ke alakaʻi wela kiʻekiʻe, no laila e emi iho ka pilikia o ka mea hana i ka wā hoʻomehana a me ka hoʻomaʻalili ʻana. ʻO ia ke kumu e kū pono ai nā ʻāpana SiC i ka haʻalulu.
5, ikaika mīkini kiʻekiʻe, ʻoʻoleʻa maikaʻi
He kiʻekiʻe loa ka ikaika mechanical o ka mea silicon carbide, e pale ana i ka deformation o ka mea. ʻOi aku ka ikaika mechanical o ka Silicon carbide ma mua o ka corundum.
6, paʻakikī kiʻekiʻe a me ke kūpaʻa ʻana i ka ʻaʻahu
He kiʻekiʻe loa ka paʻakikī o nā mea silicon carbide, a ʻo ka paʻakikī o Moss gap he 9.2 ~ 9.6, ʻo ia ka lua ma hope o ke daimana a me ka tungsten carbide. Ke hoʻohālikelike ʻia me nā mea kila metala, hāʻawi ia i ka paʻakikī kiʻekiʻe, ka coefficient haʻahaʻa o ka friction, ka friction haʻahaʻa, ka ʻili liʻiliʻi a me ke kūpaʻa maikaʻi me ka ʻole o ka lubrication. Eia kekahi, he kūpaʻa ia i nā mea o waho, e hoʻomaikaʻi ana i ka hoʻomanawanui o ka ʻili. ʻO ka silicon carbide sintered ma lalo o ke kaomi lewa
Ka hoʻohana ʻana o nā keramika silicon carbide sintered kaomi lewa
1, hana ʻana i nā mea silicon carbide o nā keramika kūikawā
ʻO ka mea Silicon carbide kahi mea me ka paʻakikī kiʻekiʻe a me ke kumukūʻai haʻahaʻa, hiki ke hana i nā huahana silicon carbide, e like me nā sila silicon carbide, nā ʻūlū silicon carbide, nā papa pale pale silicon carbide, nā ʻaoʻao silicon carbide, a me nā mea ʻē aʻe, hiki ke hoʻopili ʻia i nā sila mechanical a me nā pamu like ʻole. Sintered silicon carbide ma lalo o ke kaomi lewa
2, hana ʻana i nā mea zirconia o nā keramika kūikawā
He kiʻekiʻe ka conductivity ionic o ka seramika Zirconia, kūpaʻa kemika maikaʻi a me ke kūpaʻa kūkulu, a ua lilo ia i mea electrolyte i aʻo nui ʻia a hoʻohana ʻia. Ma ka hoʻomaikaʻi ʻana i ke kaʻina hana o ka ʻili electrolyte zirconia, ka hoʻemi ʻana i ka mahana hana a me ke kumukūʻai hana o kēia mau mea, a me ka hoʻoikaika ʻana e hoʻokō i ka ʻoihana ʻoihana he kuhikuhi koʻikoʻi nō hoʻi ia o ka noiʻi e hiki mai ana.
