2. Kev siv cov khoom nruab nrab (tsawg mus rau pua pua microns)
Cov yam ntxwv ntawm cov khoom nruab nrab
Nruab nrab-grained dawb corundum muaj zog sib tsoo quab yuam thiab cov ntaub ntawv tshem tawm muaj peev xwm, thiab particle loj yog feem ntau ntawm kaum mus rau pua pua ntawm microns. Lawv tau siv dav hauv kev ua tshuab, tshwj xeeb tshaj yog nyob rau hauv lub sijhawm uas precision thiab efficiency yuav tsum sib npaug.
Daim ntawv thov scenarios
Precision sib tsoo ntawm cov khoom siv tshuab: Nruab nrab-grained dawb corundum feem ntau yog siv rau kev sib tsoo ntawm cov khoom siv tshuab, xws li bearings, gears, thiab lwm yam. Cov khoom zoo li no yuav tsum muaj qhov siab precision thiab qis nto roughness. Dawb corundum tuaj yeem tshem tawm cov ntaub ntawv zoo thiab txo lub sijhawm ua haujlwm thaum tswj xyuas qhov tseeb.
Kev tsim cov cuab yeej: Hauv kev tsim cov cuab yeej xws li riam thiab xyaum, nruab nrab-grained dawb corundum yog siv rau kev sib tsoo kom ntseeg tau qhov ntse thiab ua haujlwm ntawm cov cuab yeej. Nws zoo hnav tsis kam ncua lub neej kev pab cuam ntawm lub cuab yeej thiab txhim kho kev ua tau zoo.
3. Daim ntawv thov ntawm coarse hais (millimeter qib)
Cov yam ntxwv ntawm coarse hais
Coarse-grained dawb corundum feem ntau muaj qhov me me ntawm ob peb puas microns thiab ob peb millimeters, thiab muaj peev xwm txiav thiab sib tsoo. Hom particle no tsuas yog siv rau kev ua haujlwm hnyav thiab kev sib tsoo, thiab tuaj yeem txiav thiab zom cov ntaub ntawv nyuaj.
Daim ntawv thov scenarios
Hnyav-duty txiav: Coarse-grained dawb corundum feem ntau yog siv rau kev txiav hlau, ceramics, thiab pob zeb. Piv txwv li, hauv kev ua hlau, dawb corundum sib tsoo lub log tuaj yeem txiav cov ntaub ntawv nyuaj xws li stainless hlau thiab hlau alloy, nrog rau kev txiav kom zoo thiab cov npoo du.
Kev sib tsoo ntawm cov khoom siv hauv tsev: Hauv kev tsim kho, coarse-grained dawb corundum yog siv rau kev sib tsoo cov ntaub ntawv xws li pob zeb thiab pob zeb. Nws txoj kev sib tsoo muaj peev xwm tuaj yeem tshem tawm cov khoom siv sai sai kom ua tiav cov nyhuv ntawm qhov xav tau thaum ua kom lub neej ntev dua.
Refractory ntau lawm: Hauv kev tsim cov khoom siv refractory, coarse-grained dawb corundum yog siv los ua ib qho ntawm cov khoom siv tseem ceeb rau cov ntaub ntawv hauv ob sab phlu ntawm cov kub kub thiab cov khoom siv kho cua sov. Vim nws siab refractoriness thiab hnav tsis kam, nws ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv refractory.
4. Qhov tseem ceeb thiab kev xaiv ntawm dawb corundum particle cais
Kev faib tawm ntawm cov corundum dawb tsis tsuas yog cuam tshuam rau lub cev ntawm cov khoom, tab sis kuj ncaj qha cuam tshuam rau nws cov txiaj ntsig ntawm daim ntawv thov. Thaum xaiv cov xim dawb corundum, yam xws li qhov yuav tsum tau ua kom tiav, cov khoom siv tshem tawm, thiab kev ua tiav yuav tsum tau txiav txim siab.

Tsis tas li ntawd, lub uniformity ntawm particle tis ntawm dawb corundum kuj yog ib qho tseem ceeb xav txog. Uniform particle tis tuaj yeem ua kom ruaj khov thaum lub sijhawm ua haujlwm, txo qhov kev hloov pauv hauv kev ua, thiab txhim kho tag nrho kev ua haujlwm zoo.
Xaus
Vim nws qhov sib txawv particle kev faib tawm, dawb corundum tuaj yeem siv dav hauv ntau yam kev lag luam. Los ntawm precision polishing mus rau hnyav txiav, dawb corundum nrog cov khoom sib txawv ua pov thawj qhov zoo ntawm kev ua tau zoo. Los ntawm kev txiav txim siab xaiv thiab siv cov xim dawb corundum, cov txiaj ntsig ua tau zoo thiab meej tuaj yeem ua tiav kom tau raws li kev xav tau ntawm kev lag luam niaj hnub no.
