Xim av Aluminium Oxide 01
Brown corundum, los yog BFA, yog cov khoom tsim los ntawm cov khoom zoo bauxite thiab lwm yam khoom siv raw. Nws yog tsim nyob rau hauv high-kub hluav taws xob arc furnaces los ntawm ib tug complex melting txheej txheem. Cov khoom uas tau tshwm sim yog ib qho nyuaj thiab tawv abrasive haum rau ntau hom kev lag luam....

Brown corundum yog ib qho tawv, ruaj, muaj ntau yam khoom siv abrasive uas tuaj yeem pab koj daws qhov nyuaj tshaj plaws kev sib tsoo thiab polishing daim ntaub ntawv. Ua los ntawm cov khoom zoo bauxite, BFA yog melted thiab txias nyob rau hauv ua tib zoo tswj tej yam kev mob los tsim tshwj xeeb nyuaj thiab hnav-resistant khoom. Nws qhov tshwj xeeb ua ke ntawm hardness, toughness, thiab clarity ua rau BFA zoo tagnrho rau ntau yam kev siv, los ntawm kev kho deg mus rau hlau, woodworking, thiab lwm yam.
Brown corundum yog cais raws li nws cov tshuaj muaj pes tsawg leeg thiab cov qauv siv lead ua. Nws muab faib ua ob hom - tsis tu ncua hlau thiab hlau tsis tshua muaj. Ordinary xim av corundum muaj 1-3% hlau, hos low-iron xim av corundum muaj tsawg dua 0.2% hlau.
Ntawm Henan Advanced Abrades, peb muab qhov zoo tshaj plaws xim av corundum kom tau raws li koj xav tau kev lag luam. Nrog nws cov hardness superior, toughness, thiab ntom, BFA yog lub zoo meej abrasive rau ntau yam kev siv. Cia siab rau peb muab cov tshuaj abrasive zoo tshaj plaws rau koj txoj kev lag luam.
qhov zoo thiab qhov tsis zoo
Siab hardness
Brown corundum muaj Mohs hardness ntawm 9, ua rau nws yog ib qho nyuaj tshaj plaws abrades ntawm lub khw. Qhov no ua kom ntseeg tau tias nws tuaj yeem tiv taus cov ntawv thov xav tau tshaj plaws thiab xa cov txiaj ntsig zoo ib yam dhau sijhawm.
Siab toughness
Brown corundum muaj zoo heev toughness, uas ua rau nws resistant rau tawg thiab tawg. Qhov no toughness kuj ua rau nws haum rau high-pressure daim ntaub ntawv uas muaj zog abrasives yuav tsum tau.
High ceev
Qhov siab ceev ntawm cov xim av corundum xyuas kom meej tias nws tuaj yeem txiav cov ntaub ntawv tawv sai thiab ua tau zoo. Qhov ntom ntom no kuj pab txo cov plua plav tawm thaum lub sij hawm txiav, ua kom nws huv thiab nyab xeeb dua.
