Xim av Aluminium Oxideyog cornarial cornarum tsim los ntawm smelting thiab txo bauxite, carbon thiab cov ntawv pov thaiv hlau nyob rau hauv ib lub cub hluav taws arc. Cov tshuaj tseem ceeb ntawm xim av fused alumina yog al2O3, nrog cov ntsiab lus ntawm 95. {0% thiab 97.}% feem, thiab tseem muaj cov nqi me me, thiab tseem muaj cov khoom siv me me thiab lwm yam. Xim av corundum yog qhov yooj yim tshaj plaws abrasive. Cuav abrasives ua los ntawmDawb ox oxidemuaj aluminium oxide (al2O3) Cov ntsiab lus ntau dua 99%, thiab muaj cov hlau me me ntawm cov hlau oxide, silicon oxide thiab lwm yam kev sib cav, thiab yog dawb. Yog li, dab tsi yog qhov sib txawv ntawm xim av txhuas oxide thiab dawb txhuas oxide?
1. Cov ntaub ntawv sib txawv: cov ntaub ntawv nyoos ntawm xim av feded alumina yog bauxite, anthracite thiab hlau pins. Cov khoom siv raw ntawm cov xim dawb txhuas yog alumina hmoov.
2. Sib txawv siv: xim av txhuas oxide tuaj yeem siv los ua ceramics, sib tsoo, ua kom sib sib zog, thiab kuj tuaj yeem siv los ua cov ntaub ntawv refractory. Dawb corundum yog qhov tsim nyog rau kev sib tsoo cov khoom sib tsoo zoo xws li cov hlau hluav taws xob muaj zog, cov hlau ceev thiab hlau. Cov xim dawb txhuas kuj tseem tuaj yeem siv rau qhov precision Casting thiab cov ntaub ntawv Refactory.
3. Sib txawv kev ua tau zoo: Brown Aluminium oxide muaj cov yam ntxwv ntawm kev siab siab, muaj zog ntawm fluentity, qis linear nthuav coefficiention, thiab corrosion tsis kam. Dawb Aluminium oxide muaj cov yam ntxwv ntawm kev siab zoo, acid thiab alkali corrosion tsis kam, siab kub ua hauj lwm. Hauv kev sib piv, lub hardness ntawm dawb corundum yog siab dua li ntawm cov xim av corundum.
4. Cov qauv sib txawv: txawm hais tias ob qho xim av txhuas oxide thiab cov alumina aluminium ntawm dawb corundum yog siab dua 99%, thiab cov alumina cov ntsiab lus ntawm xim av corundum yog txog 95%.
5. Cov xim sib txawv: txij li cov ntsiab lus alumina ntawm cov xim dawb txhuas yog siab dua li cov xim av txhuas dawb, thiab xim av ntawm xim av yog xim av-dub.
6. Cov txheej txheem ntau lawm: Cov tshuaj dawb yog tsim los ntawm Alumina hmoov (tib cov khoom siv raw li electrolytic txhuas), thaum xim av txhuas oxide yog tsim los ntawm calceXite.
7. Cov neeg siv sib txawv: Dawb fused alumina yog siv los ntawm qee cov neeg siv high-kawg vim tias nws muaj cov txiaj ntsig zoo dua thiab cov nyhuv zoo dua. Nws feem ntau yog siv rau cov hlau, hlau nplaum sib nraus, tuav daim duab pov tseg hlau, thiab lwm yam xim av yog siv dav hauv kev ua lag luam thiab tseem siv nyob rau hauv kev ua lag luam. Nws yog feem ntau yog siv rau cov hlau hardened, high-ceev steel, high-carbon hlau, thiab lwm yam.
Dawb fused alumina muaj kev txiav tej zog thiab yog siv los tshem tawm cov hlau lossis tsis yog-burrs, etc. Nws muaj cov haujlwm polishing ntawm cov ntu thiab yog qhov nruab nrab ntawm cov Abrasive. Brown fused alumina yuav tsis tshem tawm burrs nyob rau ntawm cov khoom siv hluav taws xob xws li stainless hlau, carbon hlau, thiab txhuas alloy. Kev sib tsoo ntawm xim av corundum tsis yog zoo li zoo thiab kaj li dawb corundum.
Vim li cas tus nqi ntawm xim av feded alumina siab dua li ntawm cov neeg dawb dawb?
Txhua tus neeg tsis meej pem me ntsis thaum pom qhov no.
Tom qab sib piv cov kev ua tau zoo ntawm xim av nplua alumina thiab dawb fused alumina nyob rau hauv ntau yam, thiab tus nqi ntawm dawb corundum feem ntau yog ob zaug ntawm xim av corundum.
Qhov tseeb, nws yog vim tias xim av fused alumina muaj zog irreplaceability hauv ntau daim ntawv thov.
Xim av Aluminium oxide muaj cov hnav muaj zog, yaig tsis kam thiab tawv. Nyob rau hauv cov chaw uas yog molten hlau thiab hlau yuav tsum tau ntws thiab muaj kev hnav khaub ncaws thiab hnav khaub ncaws hlau, uas muaj kev cuam tshuam ntau dua nyob rau hauv daim ntawv thov loj thiab sib sau ua ke. Piv nrog dawb corundum, cov ntsiab lus ntawm titanium oxide nyob rau hauv xim av txhuas oxide muaj zog heev, uas ua rau cov anti-yaig ua tau zoo dua li lwm cov ntaub ntawv.
Raws li cov kev xyaum ua pov thawj ntawm kaum ob ntawm cov chaw tsim khoom, cov khoom no muaj cov yam ntxwv ntawm tsis muaj kev tawg, tsis muaj hmoov thiab tsis tawg thaum lub sijhawm ua ntawv thov. Tshwj xeeb, nws cov txiaj ntsig-ua tau zoo dua li ntawm cov tsoos xim av corundum, ua rau nws ib qho kev sib sau ua zoo tshaj plaws thiab lim rau cov khoom siv xim av alumina refractory.
Ntxiv mus, xim av fused alumina noj ntau dua li cov ntaub ntawv nyoos, thiab tus nqi ntawm cov khoom siv raw dua li lwm cov ntaub ntawv raw xws li dawb corundum thiab sintereded corundum thiab sintereded corundum.
