Qhov txawv ntawm BFA thiab WFA

Brown corundumyog ib hom xim av dag corundum tsim los ntawm smelting thiab txo bauxite, carbon thiab hlau chips nyob rau hauv hluav taws xob arc rauv. Lub ntsiab chemical muaj pes tsawg leeg ntawm cov xim av corundum yog Al2O3, nws cov ntsiab lus yog 95.0% thiab 97%. Brown corundum yog qhov yooj yim tshaj plaws abrasive. Artificial abrasive ua los ntawm dawb corundum, aluminium oxide (Al2O3) cov ntsiab lus yog ntau dua 99%, thiab muaj ib qho me me ntawm cov hlau oxide, silicon oxide thiab lwm yam khoom, dawb.

** Qhov txawv ntawm xim av thiab dawb corundum: **

Kev siv sib txawv: dawb corundum yog tsim rau kev sib tsoo zoo-grained abrasives xws li high-carbon steel, high-speed steel thiab stainless hlau, thiab dawb corundum kuj siv tau rau precision casting thiab high-qib refractory ntaub ntawv. Brown corundum tuaj yeem siv los tsim cov ceramics, resin high consolidation abrasive cov cuab yeej, sib tsoo, polishing, sandblasting, precision casting, thiab lwm yam., thiab tseem tuaj yeem siv los tsim cov ntaub ntawv qib siab refractory.

Cov muaj pes tsawg leeg yog txawv: txawm hais tias ob qho tib si xim av corundum thiab dawb corundum muaj alumina, cov ntsiab lus ntawm xim av corundum alumina yog li 95%, thiab cov ntsiab lus alumina ntawm dawb corundum yog ntau tshaj 99%.

Kev ua tau zoo sib txawv: Brown corundum muaj cov yam ntxwv ntawm siab purity, zoo crystallization, muaj zog fluidity, qis coefficient ntawm linear expansion thiab corrosion kuj. Dawb corundum muaj cov yam ntxwv ntawm siab purity, zoo tus kheej ntse, acid thiab alkali corrosion kuj, kub tsis kam thiab ruaj khov kub lub xeev kev ua tau zoo. Hauv kev sib piv, qhov hardness ntawm dawb corundum yog siab dua li ntawm xim av corundum.

Txawv ntau lawm:dawb corundumyog tsim nrog txhuas oxide hmoov (tib yam raw khoom li electrolytic aluminium), thaum xim av corundum yog tsim nrog calcined bauxite.

Cov xim sib txawv: xim av corundum yog xim av thiab dub, vim hais tias cov ntsiab lus ntawm alumina ntawm dawb corundum yog siab dua li xim av corundum, yog li cov xim ntawm dawb corundum yog dawb.

Cov ntaub ntawv sib txawv: cov khoom siv raw ntawm cov xim av corundum yogbauxite, ntxiv rau anthracite thiab hlau huab. Cov khoom siv raw ntawm corundum dawb yog aluminium oxide hmoov.

Cov khoom sib txawv ntawm kev siv: dawb corundum yog siv los ntawm qee cov neeg siv high-end, vim tias nws muaj zog txiav zoo dua thiab cov nyhuv polishing zoo heev, feem ntau yog siv hauv carbon steel, alloy steel, malleable cam khwb cia hlau, tawv bronze thiab lwm yam. xim av corundum yog dav siv nyob rau hauv kev ua lag luam, thiab kuj yog ib tug loj tus naj npawb ntawm cov lag luam, feem ntau yog siv nyob rau hauv 焠 hluav taws kub steel, high-speed steel, high carbon steel thiab thiaj li nyob.

Dawb corundum muaj lub zog txiav, siv los tshem tawm cov hlau los yog cov hlau tsis yog hlau, batch burrs thiab lwm yam. Nws muaj kev ua haujlwm ntawm polishing nto ntawm qhov chaw thiab belongs rau nruab nrab polishing abrasive. Brown corundum yog siv los tshem tawm burrs ntawm qhov chaw ntawm stainless hlau, carbon steel, aluminium alloy thiab lwm yam khoom siv kho vajtse. Lub grind ntawm xim av corundum tsis zoo li zoo thiab ci li dawb corundum.
