Kufotokozera Kwachidule

White Fused Alumina ndi mchere wapamwamba kwambiri, wopangidwa.

Amapangidwa ndi kuphatikizika kwa mtundu wowongolera wa Bayer Alumina mu ng'anjo yamagetsi yamagetsi pa kutentha kwakukulu kuposa 2000˚C ndikutsatiridwa ndi kulimba pang'onopang'ono.

Kuwongolera mwamphamvu pamtundu wa zida zopangira ndi magawo ophatikizika kumatsimikizira kuti zinthu zimakhala zoyera kwambiri komanso zoyera kwambiri.

Zozizira zoziziritsa zimaphwanyidwanso, kutsukidwa ndi zonyansa zamaginito muzolekanitsa zamphamvu kwambiri za maginito ndikuziika m'tigawo ting'onoting'ono kuti zigwirizane ndi ntchito yomaliza.

Zakuthupi Ndi Njira Yopangira

White Fused Alumina ndi mchere wapamwamba kwambiri, wopangidwa.

Amapangidwa ndi kuphatikizika kwa mtundu wowongolera wa Bayer Alumina mu ng'anjo yamagetsi yamagetsi pa kutentha kwakukulu kuposa 2000˚C ndikutsatiridwa ndi kulimba pang'onopang'ono.

Kuwongolera mwamphamvu pamtundu wa zida zopangira ndi magawo ophatikizika kumatsimikizira kuti zinthu zimakhala zoyera kwambiri komanso zoyera kwambiri.

Zozizira zoziziritsa zimaphwanyidwanso, kutsukidwa ndi zonyansa zamaginito muzolekanitsa zamphamvu kwambiri za maginito ndikuziika m'tigawo ting'onoting'ono kuti zigwirizane ndi ntchito yomaliza.

Kugwiritsa ntchito

Mizere yodzipereka imapanga zinthu zosiyanasiyana.

White Fused Alumina ndiyowonongeka kwambiri chifukwa chake imagwiritsidwa ntchito muzinthu za Vitrified Bonded Abrasives komwe kuzizira, kudula mwachangu ndikofunikira komanso kupanga zodzitchinjiriza za Alumina zoyera kwambiri.Ntchito zina zimaphatikizapo kugwiritsa ntchito Coated Abrasives, chithandizo chapamwamba, Matailo a Ceramic, Anti-Skid Paints, Fluidized Bed Furnaces ndi Khungu / Dental Care.
