ʻO ka mea hoʻoheheʻe paʻakikī loa ʻo Silicon Carbide Grit

ʻO Junda Silicon Carbide Grit ka mea pahū paʻakikī loa i loaʻa. Hana ʻia kēia huahana kiʻekiʻe i kahi ʻano ʻāpana blocky a angular. E wāwahi mau kēia mea hana e hopena ai i nā ʻoi a ʻokiʻoki. ʻO ka paʻakikī o Silicon Carbide Grit e ʻae i nā manawa pahū pōkole e pili ana i nā mea hana palupalu.

Ma muli o kona mau waiwai kemika paʻa, ka conductivity wela kiʻekiʻe, ka coefficient hoʻonui wela haʻahaʻa, a me ke kūpaʻa maikaʻi o ka ʻaʻahu ʻana, he nui nā hoʻohana ʻē aʻe o ka silicon carbide ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he abrasives. No ka laʻana, hoʻopili ʻia ka pauka silicon carbide i ka impeller a i ʻole ka cylinder o kahi turbine wai ma o kahi kaʻina hana kūikawā. Hiki i ka paia o loko ke hoʻomaikaʻi i kona kūpaʻa ʻana i ka ʻaʻahu a hoʻolōʻihi i kona ola lawelawe ma 1 a 2 mau manawa; ʻo ka mea refractory kiʻekiʻe i hana ʻia mai ia mea he kūpaʻa haʻalulu wela, liʻiliʻi ka nui, māmā ke kaumaha, ikaika kiʻekiʻe a me ka hopena mālama ikehu maikaʻi. ʻO ka silicon carbide haʻahaʻa (aia ma kahi o 85% o SiC) he deoxidizer maikaʻi loa. Hiki iā ia ke wikiwiki i ka wikiwiki o ka hana kila, a hoʻomaʻamaʻa i ka kaohi ʻana o ka haku mele kemika a hoʻomaikaʻi i ke ʻano o ke kila. Eia kekahi, hoʻohana nui ʻia ka silicon carbide e hana i nā koʻokoʻo silicon carbide no nā mea hoʻomehana uila.

He paʻakikī kiʻekiʻe loa ko ka Silicon carbide, me ka paʻakikī Mohs o 9.5, ʻo ia ka lua ma hope o ke daimana paʻakikī loa o ka honua (10). Loaʻa iā ia ka conductivity thermal maikaʻi loa, he semiconductor, a hiki ke kū i ka oxidation i nā mahana kiʻekiʻe.

Ma muli o kona mau waiwai kemika paʻa, ka conductivity wela kiʻekiʻe, ka coefficient hoʻonui wela haʻahaʻa, a me ke kūpaʻa maikaʻi o ka ʻaʻahu ʻana, he nui nā hoʻohana ʻē aʻe o ka silicon carbide ma waho aʻe o ka hoʻohana ʻia ʻana ma ke ʻano he abrasives.

Eia kekahi, hoʻohana nui ʻia ka silicon carbide e hana i nā koʻokoʻo silicon carbide no nā mea hoʻomehana uila.
