ʻO ka carbide silicon ʻōmaʻomaʻo a me ka carbide silicon ʻeleʻele: Nā ʻokoʻa hohonu ma mua o ke kala
Ma ke kahua ākea o nā mea hana ʻoihana,carbide silicon ʻōmaʻomaʻoa meʻeleʻele silicon carbide ua ʻōlelo pinepine ʻia pū. He mau mea abrasive koʻikoʻi nā mea ʻelua i hana ʻia e ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe i loko o nā umu kū'ē me nā mea maka e like me ke one quartz a me ka petroleum coke, akā ʻoi aku ka nui o ko lākou ʻokoʻa ma mua o nā ʻokoʻa kala ma ka ʻili. Mai nā ʻokoʻa liʻiliʻi o nā mea maka, a hiki i ka ʻokoʻa o nā ʻano hana, a hiki i ka ʻokoʻa nui o nā hiʻohiʻona noi, ua hoʻohālikelike pū kēia mau ʻokoʻa i nā kuleana kūikawā o nā mea ʻelua ma ke kahua ʻoihana.
1 ʻO ka ʻokoʻa o ka maʻemaʻe o ka mea maka a me ke ʻano o ke aniani e hoʻoholo ai i nā ʻano like ʻole o nā mea ʻelua.
ʻO ka carbide silicon ʻōmaʻomaʻoHana ʻia me ka petroleum coke a me ke one quartz ma ke ʻano he mau mea nui, a hoʻohui ʻia ka paʻakai no ka hoʻomaʻemaʻe ʻana. Ma o kēia kaʻina hana, ua hoʻemi ʻia ka nui o ka haumia, a he ʻōnaehana hexagonal maʻamau ke kristal me nā kihi ʻoi a me nā kihi. He maʻalahi ka hana ʻana i nā mea maka o ka silicon carbide ʻeleʻele, a ʻaʻohe paʻakai i hoʻohui ʻia. ʻO nā mea haumia e like me ka hao a me ka silicon i waiho ʻia i loko o nā mea maka e hoʻolilo i kona mau ʻāpana kristal i ʻano like ʻole a poepoe a palaka ma nā kihi a me nā kihi.
2 ʻO nā ʻokoʻa i nā mea maka a me nā ʻano hana e alakaʻi ai i nā ʻano kino like ʻole o nā mea ʻelua.
Ma ke ʻano o ka paʻakikī, ʻo ka paʻakikī Mohs ocarbide silicon ʻōmaʻomaʻoʻo ia ma kahi o 9.5, ʻo ka lua wale nō i ka daimana, a hiki ke hana i nā mea paʻakikī kiʻekiʻe; ʻo ka silicon carbide ʻeleʻele ma kahi o 9.0, me ka paʻakikī haʻahaʻa iki. Ma ke ʻano o ka density, ʻo ka silicon carbide ʻōmaʻomaʻo he 3.20-3.25g/cm³, me kahi ʻano paʻa; ʻo ka silicon carbide ʻeleʻele he 3.10-3.15g/cm³, he palupalu iki. Ma ke ʻano o ka hana, he maʻemaʻe kiʻekiʻe ka silicon carbide ʻōmaʻomaʻo, conductivity thermal maikaʻi, conductivity uila a me ke kūpaʻa wela kiʻekiʻe, akā he palupalu a maʻalahi hoʻi e uhaʻi i nā lihi hou; ʻo ka silicon carbide ʻeleʻele he nāwaliwali iki ka conductivity thermal a me ka conductivity uila, haʻahaʻa ka brittleness, a ʻoi aku ka ikaika o ka pale ʻana i ka hopena o nā ʻāpana.
3 Hoʻoholo nā ʻokoʻa hana i ke kiko o ka noi o nā mea ʻelua.
Loaʻa i ka silicon carbide ʻōmaʻomaʻopaʻakikī kiʻekiʻea me nā ʻāpana ʻoi, a maikaʻi hoʻi i ka hana ʻana i nā mea paʻakikī kiʻekiʻe a me nā mea paʻakikī haʻahaʻa: ma ke kahua ʻaʻole metala, hiki ke hoʻohana ʻia no ka wili aniani, ka ʻoki ʻana i ka seramika, nā wafers silicon semiconductor, a me ka polishing sapphire; i ka hana metala, loaʻa iā ia ka hana hana kiʻekiʻe kiʻekiʻe no nā mea e like me ka carbide cemented a me ke kila paʻakikī, a hoʻohana nui ʻia i nā huahana e like me nā huila wili a me nā disc ʻoki. Hoʻoponopono nui ka silicon carbide ʻeleʻele i nā mea paʻakikī haʻahaʻa, paʻakikī kiʻekiʻe a kūpono no ka hana ʻana i nā metala non-ferrous a me nā mea refractory e like me ka hao hoʻolei, keleawe a me ka alumini. I nā hiʻohiʻona paʻakikī e like me ka deburring castings a me ka wehe ʻana i ka popo o ke kila, ua lilo ia i koho maʻamau i ka ʻoihana ma muli o kona kumukūʻai kiʻekiʻe.
ʻOiai ʻo ka silicon carbide ʻōmaʻomaʻo a meʻeleʻele silicon carbideNo ka ʻōnaehana mea silicon carbide, ʻokoʻa loa ko lākou mau waiwai kino a me ke kemika a me nā ʻano noi. Me ka hoʻomau ʻana o ka hana hou ʻana o ka ʻepekema mea a me ka ʻenehana hana, manaʻo ʻia ka silicon carbide ʻōmaʻomaʻo a me ka silicon carbide ʻeleʻele e hoʻokō i ka hoʻonui ʻana o ka noi ma nā kahua ʻenehana kiʻekiʻe e like me ka hana semiconductor, ka wili pololei, a me ka ikehu hou, e hāʻawi ana i ke kākoʻo mea koʻikoʻi no ka hoʻomohala kiʻekiʻe o ka ʻoihana hou.
