Fused Alumina Abrasives
Corundum abrasives, tseem hu ua Fused Alumina, nws yog cov ntaub ntawv tseem ceeb hauv kev sib tsoo, polishing, thiab lwm yam txheej txheem, ua lub luag haujlwm tseem ceeb hauv kev tsim khoom vim lawv lub cev thiab tshuaj lom neeg tshwj xeeb.
Corundum abrasives tuaj yeem muab faib ua ntau hom raws li lawv qhov muaj pes tsawg leeg, txheej txheem kev npaj, thiab cov yam ntxwv ua haujlwm.
Txhua hom muaj nws tus kheej tsim cov xwm txheej, cov khoom, thiab thaj chaw thov.
Hauv qab no yog cov lus qhia ntxaws ntxaws rau ntau hom corundum abrasives.
1. Brown Corundum Abrasives
Cov xwm txheej tsim:Brown corundum feem ntau yog tsim los ntawm siab - kub melting thiab txias ntawm raw cov ntaub ntawv xws li bauxite thiab coke, uas ua rau crystallization. Thaum lub sij hawm siab -kub melting txheej txheem, aluminium oxide nyob rau hauv cov ntaub ntawv raw reacts nrog coke los ua corundum crystals, ib txhij tshem tawm impurities thiab cia cov muaju loj hlob.
Khoom:Xim av corundum yog xim av xim, tawv heev, thiab tawv, muab tus kheej zoo heev -sharpening thiab sib tsoo efficiency. Nws cov qauv siv lead ua tso cai rau cov khoom abrasive txuas ntxiv nthuav tawm cov npoo tshiab thaum lub sij hawm sib tsoo, tswj kev sib tsoo.
Daim ntawv thov:Brown corundum abrasives yog dav siv nyob rau hauv metalworking vim lawv siab hardness, toughness, tus kheej -sharpening, thiab sib tsoo efficiency.
Nws yog feem ntau siv rau machining cov ntaub ntawv hauv qab no:
Hlau:Brown corundum yog ib qho uas feem ntau siv rau hauv kev ua hlau, tshwj xeeb tshaj yog rau kev sib tsoo thiab txiav cov hlau zoo tib yam. Nws cov hardness siab thiab hnav tsis kam ua rau nws ua tau zoo heev hauv cov khoom siv no.
Hlau Casting:Brown corundum kuj nthuav tawm kev sib tsoo zoo ntawm cov hlau nrog cov ntsiab lus hlau siab, xws li cam khwb cia hlau. Nws zoo tshem tawm qhov tsis xws luag thiab qhov tsis sib xws, txhim kho qhov zoo ntawm workpieces.
Lwm yam khoom siv hlau:Ntxiv rau cov hlau thiab cam khwb cia hlau, xim av corundum kuj tseem siv tau los ua lwm yam khoom siv hlau, xws li kev sib tsoo ntxhib thiab txiav ntawm cov hlau tsis yog -ferrous hlau xws li tooj liab thiab txhuas.
2. Dawb Corundum Abrasives
Tsim:Dawb corundum yog tsim los ntawm siab- zoo aluminium oxide hmoov, melted nyob rau hauv ib tug siab -kub hluav taws xob arc rauv, txias, thiab ces crushed thiab tshuaj ntsuam. Thaum lub sij hawm melting txheej txheem, aluminium oxide nyob rau hauv cov khoom siv raw tau dhau los ua ib theem kev hloov pauv ntawm qhov kub thiab txias, tsim corundum crystals. Cov impurities kuj raug tshem tawm, ua rau dawb huv corundum abrasive.
Yam ntxwv:Dawb corundum yog xim dawb, me ntsis nyuaj dua li xim av corundum, muaj tus kheej zoo -sharpening zog, thiab siab sib tsoo efficiency. Nws kuj tseem ua kom muaj cua sov tsawg dua thaum lub sij hawm sib tsoo, ua rau nws tsis tshua muaj kev kub hnyiab ntawm lub workpiece.
Daim ntawv thov:Dawb corundum abrasives feem ntau yog siv rau kev sib tsoo thiab polishing, xws li hauv kev tsim cov khoom siv tsheb, cov khoom siv dav hlau, thiab cov pwm precision. Cov workpieces no feem ntau xav tau kev ua haujlwm siab thiab qhov zoo, thiab cov corundum abrasives dawb tuaj yeem ua tau raws li cov cai no.
3. Chrome Corundum Abrasives
Tsim:Chrome corundum, tseem hu ua liab fused alumina, nws yog tsim los ntawm kev ntxiv ib qho nyiaj ntawm chromium oxide rau corundum. Thaum lub sij hawm siab -kub melting txheej txheem, chromium oxide reacts nrog txhuas oxide los ua chromium- muaj corundum crystals, thaum impurities raug tshem tawm thiab muaju loj hlob.
Yam ntxwv:Chrome corundum feem ntau yog roses -liab los yog liab dawb nyob rau hauv cov xim thiab nthuav tawm siab hardness, siab thermal stability, thiab zoo tshuaj stability. Nws cov qauv siv lead ua ua rau cov khoom abrasive kom muaj lub ntsej muag ntse thaum lub sij hawm sib tsoo, txo cov kev siv abrasive.
Daim ntawv thov:Chrome corundum abrasives feem ntau yog siv rau kev sib tsoo nyuaj - mus rau - cov khoom siv tshuab xws li cov hlau tsis muaj steel thiab tshav kub- cov hlau tsis muaj zog. Cov ntaub ntawv no, vim lawv cov hardness siab thiab tsis tshua muaj thermal conductivity, tso siab xav tau ntawm abrasives, uas chrome corundum abrasives tuaj yeem ntsib.
4. SG Abrasive
Cov Txheej Txheem Ntau Lawm:SG abrasive, tseem hu ua ceramic microcrystalline corundum, yog tsim los ntawm micron - loj aluminium oxide hmoov ua cov khoom siv raw. Nws yog synthesized thiab sintered siv ib tug series ntawm high -tech formulas thiab ib tug tshwj xeeb sol-gel txheej txheem. Cov txheej txheem no ua rau SG abrasives nrog cov qauv microcrystalline, ua rau cov qoob loo loj me dua li cov corundum abrasives zoo tib yam, mus txog qib submicron (tsawg dua 1μm). Thaum lub sij hawm tsim cov txheej txheem, nruj raw khoom specifications thiab cov txheej txheem yuav tsum tau ua kom paub tseeb tias cov superior kev ua tau zoo ntawm cov khoom kawg.
Yam ntxwv:SG abrasives muaj qhov tshwj xeeb hardness, sharpness, thiab tus kheej -ntxhiab khoom, nrog rau cov zoo zoo tuav thiab lub neej ntev kev pab cuam. Lawv cov qauv siv lead ua tshwj xeeb tso cai rau cov khoom abrasive tsis tu ncua sib cais thaum lub sijhawm sib tsoo, nthuav tawm cov npoo tshiab thiab tswj kev sib tsoo.
Daim ntawv thov:SG abrasives feem ntau yog siv rau siab -precision, siab- kev sib tsoo ua haujlwm hauv kev lag luam hlau. SG abrasives muaj ntau yam kev siv, yoog raws li cov kev xav tau ntawm ntau yam hlau thiab tsis yog- hlau workpieces. Hauv cov ntsiab lus, ntau hom corundum abrasives muaj cov khoom sib txawv, cov yam ntxwv, thiab cov chaw siv. Hauv kev siv cov tswv yim, hom abrasive tsim nyog yuav tsum raug xaiv raws li cov kev xav tau tshwj xeeb thiab cov txheej txheem txheej txheem kom ntseeg tau tias kev sib tsoo ua haujlwm thiab ua haujlwm zoo. Nyob rau tib lub sijhawm, rau kev ua cov khoom tsis yog -hlau, pob zeb diamond thiab silicon carbide abrasives feem ntau tsim nyog.
