Mea Maka a me ka hana o ka hana
ʻO White Fused Alumina he mineral synthetic kiʻekiʻe.
Hana ʻia ia e ka hui ʻana o ka Bayer Alumina māka maʻemaʻe maikaʻi i hoʻopaʻa ʻia i loko o kahi umu ahi arc i nā mahana i ʻoi aku ma mua o 2000˚C a ukali ʻia e kahi kaʻina hana paʻa lohi.
ʻO ka mana koʻikoʻi ma luna o ka maikaʻi o nā mea maka a me nā ʻāpana fusion e hōʻoia i nā huahana o ka maʻemaʻe kiʻekiʻe a me ke keʻokeʻo kiʻekiʻe.
Hoʻopili hou ʻia ka ʻōpala maloʻo, hoʻomaʻemaʻe ʻia i nā haumia magnetic i nā mea hoʻokaʻawale magnetic ikaika a hoʻokaʻawale ʻia i loko o nā hakina liʻiliʻi e kūpono i ka hoʻohana hope.
Palapala noi
Hoʻopuka nā laina hoʻolaʻa i nā huahana no nā noi like ʻole.
ʻO ka White Fused Alumina he mea maʻalahi loa a no laila ua hoʻohana ʻia i nā huahana Vitrified Bonded Abrasives kahi e pono ai ka hana ʻoki wikiwiki a me ka hana ʻana i nā refractories Alumina maʻemaʻe kiʻekiʻe.Hoʻohana ʻia nā noi ʻē aʻe i ka Coated Abrasives, Surface Treatment, Ceramic Tile, Anti-Skid Paints, Fluidized Bed Furnaces a me ka ʻili / mālama niho.
