Dawb corundum xuab zeb, dawb corundum hmoov, xim av corundum thiab lwm yam abrasives yog cov feem ntau abrasives, tshwj xeeb tshaj yog dawb corundum hmoov, uas yog thawj xaiv rau polishing thiab sib tsoo.Nws muaj cov yam ntxwv ntawm ib leeg siv lead ua, siab hardness, zoo tus kheej-sharpening, thiab kev sib tsoo thiab polishing kev ua tau zoo.Qhov zoo xws li superiority tau siv thiab nce qib hauv ntau yam kev lag luam.Yog li, yuav ua li cas xaiv thaum polishing?
Abrasive xaiv
Abrasive yog lub cev tseem ceeb uas ua lub luag haujlwm txiav hauv kev sib tsoo.Nws yog lub luag haujlwm ncaj qha rau kev ua haujlwm txiav thiab yog qhov tseem ceeb rau kev sib tsoo lub log los tsim cov kev sib tsoo.Lub abrasive yuav tsum yog xim av corundum tsim los ntawm Xinli hnav-resistant.Nws cov khoom muaj siab hardness, kub tsis kam, thermal stability thiab tshuaj stability, thiab yuav tsum muaj ib tug tej yam toughness kom nws muaj peev xwm tiv taus ib tug tej yam sib tsoo quab yuam.
Abrasive xaiv txoj cai
Thaum sib tsoo cov ntaub ntawv nrog lub zog tensile ntau dua, siv corundum abrasives nrog ntau dua toughness.Sib tsoo cov ntaub ntawv uas tsis muaj zog tensile los xaiv brittle silicon carbide abrasives.
Ntxiv nrog rau kev txiav txim siab lub zog tensile ntawm cov khoom siv ua haujlwm, qhov nyuaj ntawm cov khoom siv ua haujlwm kuj yog lub hauv paus xaiv tseem ceeb thaum xaiv cov abrasives.Feem ntau hais lus, lub hardness ntawm abrasive yuav tsum yog 2-4 zaug siab dua qhov hardness ntawm cov khoom ua haujlwm.Txwv tsis pub, cov nplej abrasive nrog qis hardness yuav passivated sai sai thaum lub sij hawm high-ceev txiav thiab poob lub peev xwm txiav, uas yuav ua rau lub log durability tsawg dhau thiab cuam tshuam rau kev txiav.efficiency, thiab kev ua tau zoo tsis tuaj yeem lav.Yog li ntawd, qhov siab dua qhov hardness ntawm cov khoom siv ua haujlwm, qhov siab dua qhov hardness ntawm abrasive yuav tsum yog.
Xaiv cov khoom abrasive
Kev txiav txim siab yuav tsum tau muab rau cov tshuaj muaj peev xwm tshwm sim hauv cov txheej txheem sib tsoo.Nyob rau hauv qhov chaw sib tsoo, abrasives, binders, workpiece cov ntaub ntawv, sib tsoo kua thiab cua yog nquag mus rau spontaneous tshuaj tiv thaiv nyob rau hauv lub catalytic txiav txim ntawm sib tsoo kub thiab sib tsoo quab yuam.Thaum siv cov hlau, cov abrasive hnav sai dua li ntawm corundum abrasive thaum sib tsoo hlau.Qhov laj thawj tseem ceeb rau qhov no yog cov tshuaj tiv thaiv muaj zog ntawm silicon carbide abrasive thiab cov hlau.
Tsis tas li ntawd, lub thermal stability ntawm lub abrasive yuav tsum tau txiav txim siab thaum xaiv ib qho abrasive.Thaum sib tsoo qee cov ntaub ntawv nyuaj-rau-sib tsoo, lwm yam kev sib tsoo tshwm sim thaum qhov chaw sib tsoo yog qhov ua rau muaj qhov kub siab dua.
