Brown Fused Alumina rau Refractory
Brown Fused Alumina, los yog BFA, yog cov khoom tsim los ntawm cov khoom zoo bauxite thiab lwm yam khoom siv raw. Nws yog tsim los ntawm ib tug complex txheej txheem ntawm fusion nyob rau hauv hluav taws xob arc furnaces ntawm high kub. Cov khoom tsim tau yog ib qho nyuaj thiab tawv abrasive uas haum rau ntau hom kev lag luam.
Cov tshuaj muaj pes tsawg leeg: Al2O3: 95.5 feem pua - 97.5 feem pua, Fe2O3: 0.5 feem pua {{10}}}0 feem pua, SiO2: 1.{{ 19}} feem pua - 1.5 feem pua , TiO2: 2.0 feem pua - 3.0 feem pua

Brown Fused Alumina (BFA) yog ib qho tawv, ruaj khov, thiab muaj ntau yam khoom siv abrasive uas tuaj yeem pab koj daws tau txawm tias qhov nyuaj tshaj plaws kev sib tsoo thiab polishing daim ntaub ntawv. Ua los ntawm cov khoom zoo bauxite, BFA yog fused thiab txias raws li kev tswj xyuas kom zoo, ua rau cov khoom lag luam tshwj xeeb thiab hnav-tiv taus. Nws qhov tshwj xeeb ua ke ntawm hardness, toughness, thiab sharpness ua rau BFA zoo tagnrho rau ntau yam kev siv, los ntawm kev npaj nto mus rau metalworking, woodworking, thiab lwm yam.
Brown fused alumina yog cais raws li nws cov tshuaj muaj pes tsawg leeg thiab crystalline qauv. Nws tau muab faib ua ob hom - tsis tu ncua thiab tsis tshua muaj hlau. Cov xim av fused alumina tsis tu ncua muaj {{{0}}} feem pua ntawm cov hlau, qhov qis hlau xim av fused alumina muaj tsawg dua 0.2 feem pua hlau.
Raws li cov chaw tsim khoom lag luam hauv Shanxi, peb muab qhov zoo tshaj plaws Brown Fused Alumina kom tau raws li koj qhov kev xav tau. Nrog nws cov hardness superior, toughness, thiab ceev, BFA yog lub zoo meej abrasive rau ntau yam kev siv. Cia siab rau peb los muab koj cov tshuaj abrasive zoo tshaj plaws rau koj txoj kev lag luam.
