Dab tsi yuav tsum ua raws li cov hauv paus ntsiab lus thaum xaiv cov abrasives?

Abrasive yog ib yam khoom tseem ceeb heev rau cov cuab yeej abrasive, uas ncaj qha ntsig txog qhov zoo thiab siv cov khoom siv abrasive. Yog li ntawd, muaj qee lub hauv paus ntsiab lus uas yuav tsum tau ua raws li thaum xaiv. Yuav ua raws li cov ntsiab cai tshwj xeeb dab tsi?

Yog tias cov khoom sib tsoo nrog lub zog tensile siab, nws yog qhov zoo rau xaiv corundum abrasives nrog ntau dua toughness. Thaum sib tsoo cov ntaub ntawv uas tsis muaj zog tensile, nws yog qhov zoo siv silicon carbide abrasives nrog ntau dua brittleness.

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 cov abrasive yuav tsum ntau tshaj 2-4 zaug siab tshaj qhov hardness ntawm cov khoom workpiece. Txwv tsis pub, qis hardness abrasive nplej yuav sai sai passivate thiab poob lawv tej peev xwm thaum lub sij hawm high-ceev txiav, ua lub sib tsoo log durability tsawg heev thiab cuam tshuam rau cov txiav. efficiency, thiab kev ua tau zoo tsis tuaj yeem lav. Yog li ntawd, qhov nyuaj ntawm cov khoom siv ua haujlwm yog, qhov nyuaj ntawm abrasive yuav tsum yog.

Kev xaiv ntawm cov khoom abrasive yuav tsum tau coj mus rau hauv tus account muaj peev xwm tshuaj tiv thaiv nyob rau 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 spontaneous tshuaj tiv thaiv nyob rau hauv lub catalytic txiav txim ntawm sib tsoo kub thiab sib tsoo quab yuam. Cov kev ntsuam xyuas tau ua pov thawj tias silicon carbide sib tsoo cov cuab yeej Thaum sib tsoo hlau, cov khoom siv abrasive yog nrawm dua li thaum corundum abrasive sib tsoo hlau. Qhov laj thawj tseem ceeb yog cov tshuaj tiv thaiv muaj zog ntawm silicon carbide abrasive thiab hlau.

Tsis tas li ntawd, thaum xaiv cov abrasives, cov thermal stability ntawm cov abrasives yuav tsum tau xav txog. Thaum sib tsoo qee cov ntaub ntawv nyuaj-rau-sib tsoo, thaum qhov chaw sib tsoo yog qhov kub thiab txias, cov khoom siv abrasives yuav tsum muaj qhov zoo ntawm qhov kub thiab txias hardness.

Abrasive khoom ua los ntawm txawv abrasives yeej txawv, vim hais tias kev siv cov yam ntxwv ntawm abrasives yog txawv heev, xws li hardness, hnav tsis kam, thiab lwm yam. Cov khoom tshwj xeeb abrasive tuaj yeem xaiv raws li qhov xwm txheej tshwj xeeb.
