Hauv tsev neeg loj ntawm metallographic consumables, muaj ntau yam nrog tib lub zog thiab consumables, xws limetallographic sandpaperthiab pob zeb diamond sib tsoo discs. Ob qho khoom siv no yog siv rau kev sib tsoo ntawm cov qauv. Lawv muaj tib lub luag haujlwm. Peb yuav tsum xaiv li cas ntawm lawv?
Nyob rau hauv tus txheej txheem ntawm kev npaj metallographic qauv, ntxiv rau kev txiav thiab mounting, cov kauj ruam tseem ceeb tshaj plaws yog tej zaum txoj kev sib tsoo thiab polishing. Yog tias qhov txiav tsis tsim qhov sib sib zog nqus, tsis tuaj yeem tshem tawm qhov tsis xws luag, thiab kev txhim kho kom zoo, ces qhov tseem ceeb nyob hauv kev tswj cov txheej txheem sib tsoo thiab polishing. Nyob rau hauv cov xwm txheej ntawm cov qauv kev npaj zoo, qhov zoo ntawm cov qauv kev npaj nyob ntawm seb cov khoom siv tau xaiv rau txhua txoj kev sib tsoo thiab polishing yog qhov tsim nyog. Raws li metallographic sandpaper thiab pob zeb diamond sib tsoo disc yog ob qho tib si siv rau kev sib tsoo ntxhib, tseem muaj qhov sib txawv hauv lawv daim ntawv thov. Kev nkag siab txog qhov sib txawv no yuav pab koj xaiv lawv kom tsim nyog.
Pob zeb diamond sib tsoo disc, nrog pob zeb diamond abrasive hais thiab ib qho me me ntawm 240μm mus rau 6μm, tshwj xeeb tshaj yog tsim rau kev npaj cov qauv ntawm cov ntaub ntawv siab hardness lossis superhard xws li ceramics, iav, thermal spray hlau coatings, thiab cemented carbide nrog hardness siab dua. ntau tshaj 150 HV. Ib pob zeb diamond sib tsoo disc tuaj yeem hloov yam tsawg kawg 100-200 nplooj ntawv ntawm silicon carbide metallographic sandpaper. Qhov no yog thaum qhov zoo ntawm pob zeb diamond sib tsoo discs tuaj yeem cuam tshuam. Feem ntau, thaum siv cov pob zeb diamond sib tsoo disc rau kev sib tsoo ntxhib, tsis zoo li siv cov ntawv xuab zeb metallographic, tsawg kawg yog 2 mus rau 3 qib ntawm cov txheej txheem metallographic sandpaper sib tsoo. Ib kauj ruam yog txaus, nrog tib lub siab tshem tawm tus nqi, hnav tsis kam, thiab lub neej ua haujlwm ntev nrog kev sib tsoo zoo. Cov qauv nrog zoo meej ntug tuav thiab flatness tau yooj yim tau! Qhov no yog daim ntawv thov feature ntawm pob zeb diamond sib tsoo discs.
Silicon carbide metallographic sandpaper, cov khoom abrasive yog silicon carbide hais, qhov loj me me ntawm 260μm-5μm. Rau cov ntaub ntawv uas muaj ib tug hardness qis dua 150HV los yog me ntsis harder cov ntaub ntawv nrog zoo ductility, kev siv ntawm silicon carbide metallographic sandpaper rau ntxhib sib tsoo tseem yog qhov tsim nyog xaiv. Nws tuaj yeem tshem tawm cov ntaub ntawv sai sai thiab tau txais cov khoom sib xws.
Hauv cov ntsiab lus, daim ntawv thov ntawm metallographic sandpaper hauv kev sib tsoo ntxhib nyob ntawm qhov hardness ntawm cov khoom piv nrog pob zeb diamond sib tsoo disc. Pob zeb diamond sib tsoo disc yog tsim nyog rau kev npaj cov khoom kuaj nrog ib tug hardness ntau tshaj 150HV, thaum metallographic sandpaper yog zoo tshaj plaws siv rau kev npaj cov ntaub ntawv mus kuaj nrog ib tug hardness ntau yam ntawm tsawg tshaj li 150HV, los yog cov ntaub ntawv kuaj nrog siab hardness tab sis zoo ductility .
