Ka hoʻohana ʻana i ka corundum keʻokeʻo

Hana ʻia ka alumina keʻokeʻo mai ka pauka alumini oxide ʻenehana a hoʻomaʻemaʻe ʻia me ka hoʻohana ʻana i ka ʻenehana hou a me ka ʻokoʻa.Loaʻa i nā abrasives sandblasting nā hiʻohiʻona o ka manawa wili pōkole, kiʻekiʻe kiʻekiʻe, maikaʻi maikaʻi, a me ke kumu kūʻai haʻahaʻa.ʻO ka mea nui he alumini oxide (Al2O3) me ka ʻike ma luna o 98%, a loaʻa kahi liʻiliʻi o ka hao hao, silicon oxide, a me nā mea ʻē aʻe.He keʻokeʻo lākou i ka waihoʻoluʻu a maʻalili ʻia ma hope o ka hoʻoheheʻe ʻia ʻana ma kahi wela kiʻekiʻe ma mua o 2000 degere i loko o ke aniani uila.Hoʻopili ʻia lākou a hoʻohālikelike ʻia, hoʻokaʻawale ʻia e wehe i ka hao, a hoʻopaʻa ʻia i nā ʻāpana like ʻole.ʻOkoʻa ko lākou ʻano, ʻoʻoleʻa kiʻekiʻe, a ua hana nā ʻāpana i nā kihi ʻoi.
