Silicon Carbide

He mea paakiki loa ka Silicon carbide (Mohs hardness 9.25), he mea kemika a hehee ole. Loaʻa i ka Silicon Carbide kahi conductivity thermal kiʻekiʻe, he coefficient haʻahaʻa o ka hoʻonui ʻana i ka wela, he haʻalulu wela a me ka abrasion kūpaʻa a he ikaika i nā wela kiʻekiʻe. ʻO nā waiwai like ʻole o Silicon carbide e lilo ia i mea pono i nā noi like ʻole.
ʻElua mau ʻano maʻamau maʻamau: ʻeleʻele silikon carbide a me ka ʻōmaʻomaʻo silikon carbide. Loaʻa i ka carbide silika ʻeleʻele nā ​​sic ma kahi o 95%, no laila ʻoi aku ka paʻakikī ma mua o ka carbide silika ʻōmaʻomaʻo. Hoʻohana nui ʻia ia no ka hana ʻana i nā mea ikaika tensile haʻahaʻa e like me ke aniani, ka seramika, ka pōhaku, ka mea refractory, ka hao a me ka metala nonferrous etc. Green silicon carbide loaʻa nā sic ma kahi o 97% ma luna me ka hoʻomaʻamaʻa ponoʻī maikaʻi, no laila ua hoʻohana ʻia no ka hana ʻana i ka alloy paʻakikī. , titanium alloy a me ke aniani aniani a me ka ʻaʻahu cylinder a me nā mea hana ʻoki maikaʻi.

Pono:
Loaʻa i ka Silicon carbide nā waiwai kemika paʻa, kiʻekiʻe thermal conductivity, haʻahaʻa haʻahaʻa hoʻonui hoʻonui, a me ke kūpaʻa maikaʻi. Ma waho aʻe o ka hoʻohana ʻana e like me nā abrasives, he nui nā mea hoʻohana ʻē aʻe, e like me: ka uhi ʻana i ka pauka silicon carbide ma luna o nā impellers turbine wai a i ʻole nā ​​poloka cylinder me kahi kaʻina hana kūikawā Hiki i ka pā i loko ke hoʻomaikaʻi i kona pale ʻana a hoʻolōʻihi i kona ola lawelawe e 1 ~ 2 mau manawa. ; ʻO ka mea refractory i hana ʻia me ia he kūʻē i ka wela, ka liʻiliʻi, ke kaumaha māmā a me ka ikaika kiʻekiʻe, a he hopena hoʻōla maikaʻi. ʻO ka carbide silicon haʻahaʻa (loaʻa ma kahi o 85% SiC) kahi deoxidizer maikaʻi loa. Hiki iā ia ke hoʻoikaika i ka wikiwiki o ka hana kila, a hoʻomaʻamaʻa i ka mana o ka haku mele a hoʻomaikaʻi i ka maikaʻi o ke kila. Eia kekahi, hoʻohana nui ʻia ka carbide silicon e hana i nā koʻokoʻo silicon carbide no nā mea hoʻomehana uila.
