Dawb Corundum, Chrome Corundum thiab Brown Corundum Sib txawv
Qhov ncaj qha pom qhov sib txawv xim:
Brown corundum: xim av
Dawb corundum: dawb
Chrome corundum: Rose liab los yog Burgundy liab
Hardness thiab toughness yog txawv:
Hardness: Dawb alumina> Liab alumina> Brown alumina
(Dawb corundum yog 9.0, xim av corundum yog 8.5-8.9, liab corundum yog 9.1)
Toughness: Brown corundum> Liab corundum> Dawb corundum
Sib txawv muaj pes tsawg leeg:
Dawb corundum: Nrog zoo aluminium oxide hmoov ua raw khoom, dawb corundum yog crystallized los ntawm hluav taws xob melting.
Dawb corundumxuab zeb feem ntau yog {{{0}}mm, 1-3mm, 3-5mm, 5-8mm, lub cev thiab tshuaj ntsuas: Al2O3 Ntau dua lossis sib npaug li 99% Na2O Tsawg dua lossis sib npaug rau {{10}}.5% CaO Tsawg dua lossis sib npaug rau 0.4%, cov hlau nplaum tsawg dua lossis sib npaug li 0.003%.
Chrome corundum: Nws muaj pes tsawg leeg yog-alumina, tseem hu ua liab corundum, ruby. Tam sim no kev ua lag luam feem ntau yog xim liab corundum.
Liab corundum ntxiv 22% chromium rau lub hauv paus ntawm dawb corundum, ua los ntawm hluav taws xob arc rauv melting, xim yog ntshav. Lub hardness yog me ntsis siab dua li cov xim av corundum, zoo ib yam li dawb corundum, thiab cov microhardness yuav yog 2200-2300Kg/mm2.
Brown corundum: ib lub npe hu ua carborundum, yog siv bauxite, carbon cov ntaub ntawv, hlau chips peb raw cov ntaub ntawv nyob rau hauv hluav taws xob rauv melting txo thiab ua los ntawm tan dag dag corundum, yog li lub npe no, cov tsos yog tan, toughness, microhardness nyob rau hauv 1800-2200Kg/mm2, ntim ceev Ntau dua lossis sib npaug li 3.85g/cm3. Cov tshuaj tseem ceeb ntawm cov xim av corundum yog Al2O3, nws cov ntsiab lus yog 94.5% -97%, thiab muaj me me ntawm Fe, Si, Ti thiab lwm yam. Xim av corundum kub tsis kam, refractoriness txog 1850 degree, yog dav siv los ua cov khoom siv refractory thiab abrasive.
Kev sib xyaw txiav txim cov yam ntxwv sib txawv:
Dawb corundum: dawb corundum crystallized los ntawm electromelting, nrog siab purity, zoo tus kheej ntse, acid thiab alkali corrosion kuj, kub tsis kam thiab ruaj khov kub lub xeev kev ua tau zoo. Dawb corundum hardness yog me ntsis siab dua xim av corundum, toughness yog me ntsis qis, siab purity, zoo tus kheej ntse, muaj zog sib tsoo muaj peev xwm, me me tshav kub, high efficiency, acid thiab alkali corrosion kuj, kub thermal stability.
Brown corundum: Nws muaj cov yam ntxwv ntawm kev tsis pib, tsis yog pulverization thiab tsis tawg nyob rau hauv daim ntawv thov txheej txheem, tshwj xeeb tshaj yog nws cov nqi kev ua tau zoo yog ntau dua li cov tsoos xim av corundum, thiab nws dhau los ua aggregate thiab muab tub lim ntawm xim av corundum refractory.
Chrome corundum: toughness siab dua dawb corundum, me ntsis qis dua xim av corundum.
Scope ntawm daim ntawv thov
1. Dawb corundum yog tsim rau kev tsim cov ceramics, resin-consolidated abrades, sib tsoo, polishing, sandblasting, precision casting (corundum for precision casting), thiab lwm yam., thiab kuj tseem siv tau los tsim cov ntaub ntawv qib siab refractory. Haum rau ntau yam khoom siv high-end, thev naus laus zis lossis kho vajtse thiab lwm yam khoom siv kho kom zoo nkauj, sandblasting nto dawb tsis muaj impurities, tsis muaj teeb meem tu. Fine dawb corundum tuaj yeem siv ua polishing taub hau.
2. Brown corundumparticle loj xuab zeb yog ua los ntawm tes xaiv xim av corundum thaiv, ua tiav los ntawm dov, pob milling, Barmack thiab lwm yam khoom siv, nrog particle loj ntawm F8-F325, feem ntau yog siv rau polishing, sib tsoo, muaj kev sib tsoo, thiab lwm yam., thiab tseem tuaj yeem ntxuav, pickling thiab lwm txoj kev ua raws li cov neeg siv khoom xav tau, kom tau raws li cov kev xav tau sib txawv ntawm cov neeg siv khoom.
3. Cov abrades ua los ntawm chrome corundum yog tsim rau kev sib tsoo high-carbon steel, high-speed steel thiab nyias-walled qhov chaw. Abrades kuj tseem siv tau los ua kev sib tsoo, polishing cov ntaub ntawv, precision casting xuab zeb, txau cov ntaub ntawv, tshuaj catalyst carriers, tshwj xeeb ceramics, advanced refractory khoom, thiab lwm yam.
