Kulimba Kwambiri Kwa Njere Za Brown Wophatikiza Alumina, Wokwanira Kuti Abrasives Ndi Refractorie

Brown aluminium oxide
BFA
Brown corundum

Kufotokozera Kwachidule

Brown Fused Alumina amapangidwa ndi kusungunuka kwa Calcined Bauxite mu ng'anjo yamagetsi yamagetsi pa kutentha kuposa 2000 ° C. Njira yolimbitsa pang'onopang'ono imatsatira kuphatikizika, kuti ipereke makhiristo a blocky. Thandizo losungunuka pochotsa sulfure yotsalira ndi kaboni, Kuwongolera mwamphamvu pamiyezo ya Titania panthawi yophatikiza kumatsimikizira kulimba kwa mbewuzo.

Kenako zoziziritsa zoziziritsa kukhosi zimaphwanyidwanso, kutsukidwa ku zinyalala zamaginito muzolekanitsa zamphamvu kwambiri za maginito ndikuziika m'tigawo ting'onoting'ono kuti zigwirizane ndi ntchito yomaliza. Mizere yodzipereka imapanga zinthu zosiyanasiyana.

ONANI TSOPANO

Kugwiritsa ntchito

Brown Fused Alumina ndi zonyezimira zolimba, zakuthwa zomwe ndizoyenera kwambiri pogaya zitsulo zolimba kwambiri. Kutentha kwake kumapangitsa kukhala chinthu chabwino kwambiri chogwiritsidwa ntchito popanga zinthu zotsutsa. Izi zimagwiritsidwanso ntchito pazinthu zina monga kuphulika ndi kuumitsa pamwamba.

Brick/Vitrified Grade BFA : Amapangidwa pogwiritsa ntchito kalasi yapadera ya Bauxite mu magawo osakanikirana ophatikizika. Kalasi iyi ndi yoyenera kuzinthu za Njerwa / Vitrified zomwe zimalepheretsa Cracks / Fissures, Holes ndi mawanga akuda pamapeto pake.
