Hauv kev lag luam abrasive, muaj cov khoom tseem ceeb hu ua dawb corundum. Yog li ntawd, dab tsi yog dawb corundum? Vim li cas nws thiaj nyiam nyob rau hauv kev lag luam abrasive? Puas yog siv dav? Yuav ua li cas kom ntseeg tau nws cov txiaj ntsig hauv kev thov? Thiab ua li cas txog nws txoj kev loj hlob yav tom ntej? Peb yuav teb cov lus nug no ib los ntawm ib qho.
dawb aluminium oxide yog dab tsi?
Dawb aluminium oxideyog ib hom zoo abrasive ua los ntawm txhuas oxide hmoov los ntawm ntau cov txheej txheem xws li kub melting, kev puas tsuaj thiab shaping, sib nqus sib cais thiab tshuaj ntsuam. Nws yog zoo nyob rau hauv kev ntxhib los mos, siab hardness, thiab cov nplej ua ib tug ntse kaum thiab yog dawb. Piv nrog rau lwm cov abrasives, lub hardness ntawm dawb corundum yog me ntsis siab dua, qhov tsis kam yog me ntsis qis, tab sis lub peev xwm sib tsoo muaj zog, cov khoom siv hluav taws xob me me, kev ua haujlwm siab, thiab muaj cov kua qaub zoo thiab alkali corrosion kuj thiab kub thermal. ruaj khov.
Vim li cas thiaj xaiv dawb aluminium oxide hauv kev lag luam abrasive?
Hauv kev lag luam abrasive, cov laj thawj tseem ceeb ntawm kev xaiv dawb corundum yog raws li hauv qab no:
Ua ntej ntawm tag nrho cov, lub siab hardness thiab siab purity ntawm dawb corundum pab kom nws muab ib tug smoother, ilv qhov chaw kho nyhuv, tshwj xeeb tshaj yog nyob rau hauv high-precision ua. Qhov thib ob, kev sib tsoo zoo ntawm cov corundum dawb ua kom nws muaj kev ua haujlwm siab thaum cuam tshuam nrog ntau yam ntaub ntawv. Tsis tas li ntawd, cov kua qaub thiab alkali corrosion kuj thiab kub tsis kam ntawm dawb corundum kuj ua rau nws muaj peev xwm tswj tau kev ua haujlwm ruaj khov hauv qhov chaw hnyav.
yog dawb aluminium oxide dav siv?
Daim ntawv thov ntawm corundum dawb hauv kev lag luam abrasive yog qhov dav heev. Nws tsis yog tsuas yog cov khoom siv tseem ceeb hauv kev tsim cov cuab yeej sib tsoo xws li kev sib tsoo log, siv xuab zeb, ntawv xuab zeb, sib tsoo, tab sis kuj tau siv dav hauv kev tsim khoom siv hluav taws xob, kev lag luam hluav taws xob, kev lag luam hauv tsev, cov cuab yeej precision thiab lwm yam kev lag luam. Kev siv ntau yam ntawm corundum dawb qhia txog nws txoj kev ua tau zoo thiab siv dav.
yuav ua li cas kom ntseeg tau cov txiaj ntsig ntawm daim ntawv thov?
Txhawm rau kom ntseeg tau tias daim ntawv thov cuam tshuam ntawm corundum dawb hauv kev lag luam abrasive, cov ntsiab lus hauv qab no yuav tsum tau sau tseg:
Ua ntej ntawm tag nrho cov, qhov tsim nyog particle loj yuav tsum raug xaiv raws li kev xav tau los xyuas kom meej cov nyhuv sib tsoo thiab txo qhov kev puas tsuaj thaum lub sij hawm sib tsoo. Thib ob, tswj kev sib tsoo siab kom tsis txhob muaj siab dhau ua rau cov khoom ua haujlwm deformation thiab puas. Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tsum tswj cov corundum abrasives tsis tu ncua thiab hloov cov abrasives nrog hnyav hnyav rau lub sijhawm kom ntseeg tau tias kev sib tsoo thiab kev nyab xeeb ntawm kev tsim khoom. Nyob rau tib lub sijhawm, thaum lub sijhawm sib tsoo, kev tiv thaiv yuav tsum tau ua los tiv thaiv kev ua haujlwm ntawm tus neeg ua haujlwm noj qab haus huv. Thaum kawg, kev siv cov dej txias kom raug, txo qhov sib tsoo kub, txo cov nyhuv thermal ntawm lub workpiece, txuas ntxiv lub neej kev pab cuam ntawm cov cuab yeej sib tsoo.
Los xaus,dawb aluminium oxideoccupies ib tug tseem ceeb txoj hauj lwm nyob rau hauv lub abrasive kev lag luam nrog nws zoo heev kev ua tau zoo thiab dav daim ntawv thov teb. Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev hloov pauv ntawm kev lag luam xav tau, daim ntawv thov kev cia siab ntawm corundum dawb yuav dav dua, thiab qhov tseem ceeb tshiab yuav raug txhaj rau hauv kev tsim cov cuab yeej abrasive kev lag luam.
