ʻAʻole hoʻohana hou ʻia ke kaomi ʻana i ka ʻenekini silicon carbide ma ke ʻano he abrasive, akā ʻoi aku ka nui o nā mea hou, a hoʻohana nui ʻia i nā huahana ʻenehana kiʻekiʻe, e like me nā ceramics i hana ʻia me nā mea carbide silicon. No laila he aha nā mea maikaʻi ʻeono o ke kaomi ʻana i ka lewa e hoʻoheheʻe ai i ka silikon carbide a me ka hoʻohana ʻana i nā ceramics silicon carbide?
ʻEono mau mea maikaʻi o ke kaomi ʻana i ka lewa i hoʻopaʻa ʻia i nā mea carbide silika:
1. Haʻahaʻa haʻahaʻa
He haʻahaʻa haʻahaʻa ka haʻahaʻa haʻahaʻa o ka mea carbide silicon ma mua o ka metala, e ʻoi aku ka māmā o ka mīkini.
2. Ke kū'ē i ka corrosion
He kiʻekiʻe ka helu heheʻe ʻana o ka silicon carbide, kemika inertia, thermal shock resistance, silicon carbide i hoʻohana ʻia i nā abrasives, ceramic kilns, silicon carbide blanks, hiki ke hoʻohana ʻia i ka hoʻoheheʻe ʻana a me ka hoʻoheheʻe ʻana me ka pahu hoʻoheheʻe kūwaho kūwaho, brick, alumini electrolytic cell lining. , tungsten, kapuahi liʻiliʻi a me nā huahana silika carbide ceramic.
3, kiʻekiʻe wela, thermal hoʻonui coefficient ua hoemiia
Hana ʻia nā mea silicone carbide i nā wela kiʻekiʻe. I kekahi mau wahi wela kiʻekiʻe, pono nā mea e koi ai i ka ikaika kaʻina hana a me ka pololei o ka hoʻoponopono ʻana i hiki i ka silicon carbide ceramics ke hoʻokō. ʻO ka mahana kiʻekiʻe o ka silikon carbide e pili ana i 800, a ʻo ka mahana o ke kila he 250 wale nō. ʻO ka helu ʻana, ʻo ka awelika thermal expansion coefficient o ka silikon carbide i ka laulā o 25 ~ 1400 he 4.10-6 / C. Ana 'ia ka huina hoonui wela o ka silikoni carbide, a ua hoike mai na hualoa'a, ua oi aku ka li'ili'i o ka nui ma mua o nā mea abrasives a me nā mea wela ki'eki'e. ʻO ka carbide silika i hoʻopaʻa ʻia ma lalo o ke kaomi lewa
4, kiʻekiʻe thermal conductivity
He kiʻekiʻe ka conductivity thermal o nā mea carbide silicon, ʻo ia kekahi mea nui o nā waiwai kino o ka silicon carbide. ʻOi aku ka nui o ka conductivity thermal o ka silicon carbide ma mua o nā refractory ʻē aʻe a me nā abrades, ma kahi o 4 mau manawa o ka corundum. He haʻahaʻa haʻahaʻa ko Silicon carbide o ka hoʻonui wela a me ka conductivity thermal kiʻekiʻe, no laila e hoʻemi ʻia ka mea hana i ke koʻikoʻi wela i ka wā hoʻomehana a me ka hoʻoluʻu. ʻO kēia ke kumu e kū pono ai nā ʻāpana SiC i ka haʻalulu.
5, ikaika mechanical kiʻekiʻe, stiffness maikaʻi
He kiʻekiʻe loa ka ikaika mechanical o ka mea carbide silicon, e pale ana i ka deformation mea. ʻOi aku ka ikaika mechanical o ka Silicon carbide ma mua o ka corundum.
6, kiʻekiʻe paʻakikī a ʻaʻahu kūʻē
He kiʻekiʻe loa ka paʻakikī o nā mea carbide silicon, a ʻo ka paʻakikī o Moss gap he 9.2 ~ 9.6, ʻelua wale nō i ka daimana a me ka tungsten carbide. Ke hoʻohālikelike ʻia me nā mea kila metala, hāʻawi ia i ka paʻakikī kiʻekiʻe, haʻahaʻa haʻahaʻa o ka friction, haʻahaʻa haʻahaʻa haʻahaʻa, liʻiliʻi liʻiliʻi liʻiliʻi a me ke kūpaʻa maikaʻi ʻole me ka lubrication. Eia kekahi, kū'ē ia i nā mea o waho, e hoʻomaikaʻi ana i ka ʻae ʻana o ka ʻili. ʻO ka carbide silika i hoʻopaʻa ʻia ma lalo o ke kaomi lewa
Ka hoʻohana ʻana i ke kaomi lewa i hoʻopaʻa ʻia i ka silika carbide ceramics
1, ka hana ʻana o nā mea hana silika carbide o nā seramika kūikawā
ʻO ka mea carbide silikon he mea ia me ka paʻakikī kiʻekiʻe a me ke kumu kūʻai haʻahaʻa, hiki ke hana i nā huahana silicon carbide, e like me nā sila carbide silicon, nā lima lima silicon carbide, nā papa pōkā silicon carbide, nā profiles silicon carbide, etc., hiki ke hoʻopili ʻia i nā sila mechanical a nā pauma like ʻole. ʻO ka carbide silika i hoʻopaʻa ʻia ma lalo o ke kaomi lewa
2, zirconia mea hana o kūikawā seramika
Zirconia ceramic he kiʻekiʻe ionic conductivity, maikaʻi kemika paʻa a me ka structural paʻa, a ua lilo i mea aʻo nui a hoʻohana electrolyte mea. Ma ka hoʻomaikaʻi ʻana i ke kaʻina hana o ka zirconia ma muli o ke kiʻi electrolyte, e hōʻemi ana i ka mahana hana a me ke kumukūʻai hana o kēia mau mea, a ʻo ka hoʻoikaika ʻana e hoʻokō i ka ʻenehana he alakaʻi koʻikoʻi o ka noiʻi e hiki mai ana.
