Aluminium oxide
Lub hardness siab heev, thiab cov khoom polished feem ntau tsis hnov ​​​​mob chemical. Alumina polishing abrasives feem ntau yog siv rau polishing steel qauv. Txawm li cas los xij, nws tsis tsim nyog rau polishing aluminium thiab aluminium alloys, vim hais tias alumina abrasives yog ib qho yooj yim ua rau cov txhuas nto dull thiab tsim cov pits corrosion.

Ib qho ntawm cov khoom tseem ceeb ntawm abrasive yog nws cov hardness, nws yuav tsum nyuaj tshaj li cov khoom yuav tsum tau ua, feem ntau siv Mohs hardness tester los txiav txim qhov hardness ntawm ntau yam abrasives. Lwm yam khoom tseem ceeb ntawm abrasives yog toughness los yog ntim lub zog. Cov cuab yeej no tuaj yeem tswj tau los ntawm kev hloov pauv qhov sib xyaw, purity, particle loj thiab siv lead ua qauv ntawm cov khoom siv raw kom haum rau ntau yam kev siv.
Rau kev tsim cov khoom siv abrasive, tag nrho cov khoom siv raw, tshwj tsis yog hmoov talc thiab hlau oxide, yuav tsum tau crushed thiab tshuaj ntsuam, thiab qhov kev tshuaj ntsuam loj yuav tsum yog 4 txog 900, uas yog, txoj kab uas hla ntawm 6 hli (mm) txog 6 microns. (1/1000th ntawm 1 mm) los yog finer. Lub log sib tsoo yog qhov tseem ceeb tshaj plaws abrasive khoom, uas yog tov los ntawm abrasive thiab cov binder nyob rau hauv ib tug tej yam kev faib ua feem, thiab sintered tom qab tuag forming, thiab thaum kawg yuav tsum tau zoo li tus, sib npaug thiab overspeed xeem. Emery daim ntaub thiab cov ntawv xuab zeb yog lwm yam khoom siv abrasive nrog cov zis loj, uas yog ua los ntawm cov khoom abrasive sib koom ua ke ntawm cov khoom siv hauv paus (daim ntaub lossis ntawv) thiab txiav rau hauv cov khoom sib txawv tom qab ziab. Lwm tus yog hmoov lossis granular abrasives, uas yuav tsum tau kho los ntawm qee cov txheej txheem tom qab kev tshuaj ntsuam xyuas, xws li abrasives rau kev sib tsoo lossis polishing, feem ntau yog siv cov tshuaj ntxhia los yog siv quav ciab thiab lwm yam khoom siv kom tau raws li qhov xav tau ntawm kev ua haujlwm sib txawv.

Artificial abrasive khoom feem ntau muab faib ua corundum abrasive thiab silicon carbide abrasive ob pawg, tshwj xeeb, muaj cov hauv qab no:
1, xim av corundum abrasive, lub ntsiab tivthaiv yog Al2O3, nrog rau nruab nrab hardness, toughness, particle ntse, kuj tsis tshua muaj nqi, haum rau ua high tensile zog hlau. Microcrystalline corundum abrasives thiab dub corundum abrasives yog nws cov derivative ntau yam.
2, dawb corundum abrasive, nws hardness yog me ntsis siab dua xim av corundum, tab sis lub toughness yog tsis zoo, yooj yim rau txiav mus rau hauv lub workpiece thaum sib tsoo, zoo tus kheej-sharpening, me me tshav kub, muaj zog sib tsoo muaj peev xwm, high efficiency. Chrome corundum abrasives yog nws cov derivative ntau yam.
3, ib leeg siv lead ua corundum abrasive, nws cov khoom yog tsim los ntawm ib qho siv lead ua, thiab muaj qhov zoo ntawm ntau cov ntug txiav, siab hardness thiab toughness, sib tsoo muaj peev xwm, sib tsoo kub tsawg, qhov tsis zoo yog tias cov nqi tsim khoom siab, cov zis tawm. yog tsawg, yog li tus nqi kuj siab. Zirconium corundum abrasives kuj yog crystalline compounds nrog me ntsis qis hardness, finer siv lead ua loj thiab zoo hnav tsis kam.
4, dub silicon carbide abrasives, ntsuab silicon carbide abrasives, cubic silicon carbide abrasives, cerium silicon carbide abrasives, thiab lwm yam., belongs rau silicon carbide abrasives, lub ntsiab tivthaiv yog silicon carbide SiC, siab hardness, brittleness, ntse abrasive, zoo thermal conductivity , hnav tsis kam, tsim nyog rau kev ua haujlwm nyuaj thiab nkig hlau thiab cov khoom tsis yog xim hlau.
Haum rau txhua yam, hluav taws xob, hlau qhov chaw, kho vajtse, cuab yeej, pib qhov chaw, instrumentation, casting, kho mob, khoom siv tes ua khoom siv tes ua thiab lwm yam kev lag luam khoom nto deburring, chamfering, deoxidizing thiab nto polishing.
High sib tsoo efficiency, hnav-resistant thiab ruaj, tsis yooj yim rau lo qhov, siab ci ntsa iab!
