Yuav ua li cas kom paub qhov dawb corundum particle loj
Dawb corundum abrasive yog ib hom khoom siv abrasive, nws txoj kev tsim khoom yog qhov nyuaj heev, xaiv cov txheej txheem smelting tshwj xeeb, dawb corundum thiab tom qab ntawd ua kom puas shaping, sib nqus sib nqus rau hlau thiab lwm yam txheej txheem, tshuaj xyuas cov nyiaj faib ua ntau yam me me, tom qab ntawd yuav ua li cas. kuaj dawb corundum particle loj?
Cov hauv qab no muab cov ncauj lus kom ntxaws txog kev qhia txog ntau txoj hauv kev:
(1) kev tshuaj ntsuam xyuas. Qhov zoo: yooj yim, intuitive, cov cuab yeej siv qis, feem ntau siv rau cov qauv ntau dua 40um. Disadvantages: Qhov tshwm sim yog cuam tshuam zoo heev los ntawm tib neeg yam thiab sieve deformation.
(2) microscope (daim duab) txoj kev. Qhov zoo: yooj yim, intuitive, tuaj yeem tshawb xyuas, tsim nyog rau kev faib nqaim (loj thiab me me qhov piv txwv tsawg dua 10: 1) ntawm cov qauv. Disadvantages: cov neeg sawv cev tsis zoo, kev tsom xam ntawm kev faib tawm dav ntawm cov qauv yog teeb meem ntau, tsis tuaj yeem txheeb xyuas tsawg dua 1um ntawm cov qauv.
(3) Kev daws teeb meem (nrog rau kev sib haum xeeb ntawm lub ntiajteb txawj nqus thiab Lixin kev daws teeb meem). Qhov zoo: maj mam ua haujlwm, kev ua haujlwm tsis tu ncua ntawm cov cuab yeej, tus nqi qis, qhov raug zoo thiab rov ua dua, kev ntsuas dav dav. Disadvantages: lub sij hawm xeem yog ntev, lub lag luam yog ntau nyuaj.
Kev siv cov khoom siv dawb corundum hnav-tiv taus hauv kev lag luam aviation Hauv xyoo 1970, ntau dua 500 qhov chaw ntawm cov ntaub ntawv hnav-resistant tau thermal sprayed nyob rau hauv lub cav aviation turbine, thiab ntau tshaj 2, 000 qhov chaw ntawm hnav-resistant cov ntaub ntawv tau raug. thermal sprayed nyob rau hauv niaj hnub tshiab turbine cav, txog 3, 000 qhov chaw. Lub thermal txau ntawm cov ntaub ntawv hnav-tiv taus ntawm qhov chaw tau dhau los ua cov txheej txheem tseem ceeb thiab tseem ceeb hauv kev lag luam aviation. Zoo li dawb corundum thiab lwm yam hnav-tiv taus cov ntaub ntawv hauv kev lag luam aviation yog cov ntawv thov ua ntej ntawm thermal spraying technology txheej chav ua haujlwm, tab sis kuj tseem muaj cov khoom siv hluav taws xob zoo. daim ntawv thov ntawm thermal spraying tshuab ntau dua thiab muaj kev vam meej high-tech teb. Nrog rau kev nce qib ntawm thermal spraying technology, xws li kev txhim kho tsis tu ncua ntawm cov ntaub ntawv txheej txheej zoo, tsis tshua muaj siab plasma txau, cov nplaim hluav taws kub ceev tshuab tau tawm ib tom qab, thiab cov txheej txheem zoo tau ua kom muaj txiaj ntsig zoo. Daim ntawv thov ntawm thermal spraying technology nyob rau hauv lub aviation kev lag luam kuj yog ntau thiab ntau dua.Material thermal spraying qhov chaw ntawm txog 500, thiab niaj hnub tshiab turbine cav rau hnav-resistant khoom thermal spraying qhov chaw tau mus txog ntau tshaj 2000, txog 3000 qhov chaw. Lub thermal txau ntawm cov ntaub ntawv hnav-tiv taus rau qhov chaw tau dhau los ua cov txheej txheem tseem ceeb thiab tseem ceeb hauv kev lag luam aviation. Zoo li dawb corundum thiab lwm yam hnav-tiv taus cov ntaub ntawv hauv kev lag luam aviation yog qhov ua ntej daim ntawv thov ntawm thermal spraying technology txheej chav ua haujlwm, tab sis kuj yog cov khoom siv hluav taws xob. daim ntawv thov ntawm thermal spraying tshuab ntau dua thiab muaj kev vam meej high-tech teb. Nrog rau kev nce qib ntawm cov thev naus laus zis thev naus laus zis thev naus laus zis, xws li cov khoom siv ua haujlwm siab tau tsim los tas li. Tsis tshua muaj siab plasma spraying, high-ceev nplaim hluav taws xob tshuab tau tawm ib tom qab, thiab cov txheej zoo tau ua ib tug zoo leap. Kev siv cov thev naus laus zis thev naus laus zis hauv kev lag luam aviation kuj yog ntau thiab ntau dua.
Cov yam ntxwv ntawm cov dawb corundum frit: 1, dawb corundum frit sab sauv txheej: tseem hu ua lub hau, muab faib ua ob feem ntawm lub hauv paus sab saud, cov qauv sab saud yog nruj thiab ruaj khov, muaj cov pob zeb zoo nkauj, lub hauv paus muaj cylindrical qhov zoo. siv lead ua. Dawb corundum frit qauv yam ntxwv 2, dawb corundum frit core: cov qauv ntawm cov tub ntxhais tseem yog nruj thiab ruaj khov, thiab cov porosity loj dua. Nws yuav tsum raug sau tseg tias cov tub ntxhais ntawm cov dawb corundum frit muaj ntau cov iav iav nrog qhov thiab cov duab sib txawv, thiab cov khoom tseem ceeb ntawm cov muaju yog -AI203 tom qab kuaj pom.3. Qhov nruab nrab thiab qis ntawm cov dawb corundum frit: cov duab siv lead ua ntawm lub hauv paus yog ntxhib, tab sis cov qauv tseem nruj, thiab xim yog xim dawb thiab zoo.4, dawb corundum frit ntug: nruab nrab thiab qis crystals tsis zoo li. nruj raws li lub sab sauv ob txheej, me ntsis xoob, thiab cov muaju yog feem ntau columnar los yog granular, nrog pores thiab microcrystalline crystals ntawm ntug.
Yuav ua li cas txheeb xyuas qhov zoo ntawm cov dawb corundum abrasiveDensity kuj yog ib qho tseem ceeb qhia ntawm dawb corundum abrasives. Qhov ceev ntawm dawb corundum abrasives muab faib ua dawb corundum packing ceev thiab dawb corundum tseeb ntom.
