Dab tsi yog xim av aluminium oxide?
Brown aluminium oxide kuj hu uaxim av corundum, xim av fused alumina .(BFA) uas yog xim av dag corundum ua los ntawm melting thiab txo peb raw cov ntaub ntawv: bauxite, carbon cov khoom (xws li coke los yog anthracite), thiab hlau filings nyob rau hauv ib tug hluav taws xob arc rauv. Lub ntsiab chemical muaj pes tsawg leeg: Lub ntsiab chemical muaj pes tsawg leeg ntawm xim av corundum yog aluminium oxide (Al2O3), cov ntsiab lus ntawm uas yog nyob nruab nrab ntawm 95.00% thiab 97.00%, thiab nws kuj muaj me me ntawm hlau (Fe), silicon (Si), titanium (Ti) thiab lwm yam.
Brown corundum yog siv dav hauv kev lag luam abrasive, thiab nws cov ntawv thov tshwj xeeb yog feem ntau cuam tshuam hauv cov hauv qab no:
1. Sib tsoo lub log thiab cov cuab yeej abrasive tsim kev sib tsoo lub log
Brown corundum yog ib qho tseem ceeb raw cov ntaub ntawv rau kev sib tsoo log. Raws li cov cuab yeej sib tsoo, kev sib tsoo lub log yog siv dav hauv kev ua cov hlau thiab cov khoom tsis yog hlau. Brown corundum sib tsoo lub log tuaj yeem txhim kho kev ua haujlwm zoo thiab ua haujlwm zoo vim lawv qhov siab tawv thiab hnav tsis kam. Piv txwv li, ib lub tuam txhab tsim khoom siv hom tshiab xim av corundum sib tsoo log los ua cov txheej txheem siab precision. Kev ua tau zoo ntawm kev ua haujlwm tau nce los ntawm 30%, thiab kev ua haujlwm zoo kuj tseem txhim kho. Cov cuab yeej sib tsoo: Cov xim av corundum kuj tuaj yeem siv los tsim cov khoom sib tsoo thiab cov cuab yeej sib tsoo, nrog rau kev sib tsoo taub hau thiab sib tsoo disc rau hlau, tsis yog hlau, ceramics thiab lwm yam ntaub ntawv. Cov cuab yeej abrasive no ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm precision machining.
2. Sandblasting
xim av corundum abrasive muaj cov yam ntxwv ntawm hardness nruab nrab, siab ntim ceev, thiab zoo toughness, ua rau nws zoo tagnrho sandblasting khoom. Nws yog dav siv nyob rau hauv sandblasting kev kho mob ntawm txhuas profiles, tooj liab profiles, iav, ntxuav denim precision pwm thiab lwm yam teb. Sandblasting tuaj yeem tshem tawm cov stains, oxide txheej thiab lwm yam impurities ntawm cov khoom siv, tawm hauv qhov chaw huv thiab du.
3. Kev sib tsoo dawb
Brown corundum abrasive kuj tau siv dav hauv kev sib tsoo dawb, xws li kev sib tsoo dawb hauv cov duab raj, iav kho qhov muag, ib leeg siv lead ua silicon, lo ntsiab muag, saib iav, siv lead ua iav, jade thiab lwm yam lag luam. Kev sib tsoo dawb yog ib txoj kev sib tsoo uas tsis muaj kev sib tsoo uas tuaj yeem ua tiav high-precision machining ntawm cov duab nyuaj thiab cov npoo nkhaus.
4. Resin abrasives thiab coated abrasives Resin abrasives
Brown corundum abrasives muaj cov yam ntxwv ntawm cov xim tsim nyog, zoo hardness, toughness, haum particle cross-section hom, thiab lwm yam, thiab yog heev haum rau kev tsim cov resin abrasives. Resin abrasives yog siv dav hauv kev ua cov hlau thiab cov khoom tsis yog hlau. Coated abrasives: Brown corundum abrasives kuj yog cov ntaub ntawv raw rau cov tuam txhab ntawm cov coated abrasives xws li cov ntawv xuab zeb thiab cov ntaub qhwv. Coated abrasives yog tsuas yog siv rau saum npoo polishing thiab sib tsoo cov ntaub ntawv.
5. Muaj nuj nqi muab tub lim
Brown corundum abrasive kuj tseem siv tau los ua cov khoom siv ua haujlwm thiab feem ntau yog siv rau hauv tsheb nres qhov chaw, cov log tsheb tshwj xeeb, cov khoom siv tshwj xeeb thiab lwm yam. Hauv cov teb no, xim av corundum tuaj yeem txhim kho qhov hnav tsis kam, corrosion kuj thiab kub kub tsis kam ntawm cov khoom.
6. Hydraulic txiav
xim av corundum abrasive kuj tseem siv tau los ua kev tshaj tawm hauv kev txiav hydraulic. Hydraulic txiav siv xim av corundum abrasive raws li kev txiav nruab nrab thiab tso siab rau cov dav hlau dej siab ua haujlwm kom ua tiav kev txiav cov roj kav, hlau thiab lwm yam khoom.
xim av corundum yog dav siv nyob rau hauv kev lag luam abrasives, npog ntau lub teb xws li kev sib tsoo log thiab abrasives manufacturing, sandblasting, dawb sib tsoo, cob abrasives thiab coated abrasives, ua hauj lwm fillers, thiab hydraulic txiav. . Cov ntawv thov no qhia meej txog ntau haiv neeg thiab kev ua tau zoo ntawm cov xim av corundum ua cov khoom siv tseem ceeb.
