Nā Grits Alumina Oxide i hoʻohuihui ʻia me ka F12-F220 keʻokeʻo
ʻO ka alumina keʻokeʻo i hoʻopili ʻia
Hana ʻia ka alumina keʻokeʻo i hoʻoheheʻe ʻia me ka pauka alumina sodium haʻahaʻa kiʻekiʻe ma ka hoʻoheheʻe ʻana i ka mahana kiʻekiʻe, ka hoʻomaʻalili ʻana i ka crystallization, a laila ka wāwahi ʻana. Aia ka grit alumina keʻokeʻo i hoʻoheheʻe ʻia ma lalo o ka kaohi paʻa e mālama i ka hoʻolaha ʻana o ka nui o ka palaoa a me ke ʻano like.
