Hlau grit thiab hlau txhaj tshuaj yog ob qho tib si tseem ceeb abrasive cov ntaub ntawv siv nyob rau hauv ntau yam lag luam, xws li tsheb, aerospace, thiab kev tsim kho. Lawv yog siv rau kev npaj nto, tu, deburring, thiab peening, ntawm lwm yam kev siv. Hauv tsab ntawv blog no, peb yuav tshawb txog ntau hom steel grit thiab steel txhaj thiab lawv txawv li cas.
Steel grit yog ib hom khoom abrasive uas yog tsim los ntawm crushing steel txhaj rau hauv angular hais. Nws yog ib qho nyuaj tshaj li kev txhaj tshuaj steel thiab yog siv rau kev ua kom nruj heev, xws li tshem tawm cov txheej tuab, xeb, thiab zeb nplai. Hlau grit muaj nyob rau hauv ntau qhov ntau thiab tsawg, xws li G10 txog G120. Tus lej qis dua, qhov coarser lub grit. Qee yam nrov ntawm steel grit muaj xws li GP, GL, GH, thiab GM, uas muaj qhov sib txawv hardness qib thiab cov duab.
Hlau txhaj tshuaj, ntawm qhov tod tes, yog ib qho khoom siv hlau kheej kheej feem ntau ua los ntawm high-carbon steel. Nws yog softer dua steel grit thiab yog siv rau qhov tsis tshua muaj aggressive nto npaj, xws li tshem tawm lub teeb xeb los yog xim. Hlau txhaj tshuaj muaj nyob rau hauv ntau qhov sib txawv, xws li S70 txog S930. Tus lej loj dua, qhov txhaj tshuaj tsawg dua. Qee hom kev txhaj tshuaj steel muaj xws li S170, S230, S330, thiab S550, uas muaj cov qib hardness sib txawv thiab cov duab.
Ntxiv nrog rau qhov loj me thiab cov duab, lwm qhov tseem ceeb uas yuav tsum tau xav txog thaum xaiv ntawm steel grit thiab steel txhaj yog qib hardness. Lub hardness ntawm cov khoom abrasive yog ntsuas ntawm Mohs nplai, uas nyob ntawm 1 txog 10, nrog rau 10 yog qhov nyuaj tshaj plaws. Hlau grit feem ntau nyuaj dua li cov hlau txhaj tshuaj, nrog rau Mohs hardness ntawm ib ncig ntawm 7.5. Hlau txhaj tshuaj, ntawm qhov tod tes, muaj Mohs hardness ntawm ib ncig ntawm 6-7.
Hauv kev xaus, steel grit thiab steel txhaj tshuaj yog ob qho tib si tseem ceeb cov ntaub ntawv abrasive nrog cov yam ntxwv sib txawv thiab kev siv. Steel grit feem ntau yog siv rau kev ua kom nruj dua qhov chaw npaj, thaum cov hlau txhaj tshuaj yog siv rau kev npaj deg tsawg dua. Ob qho khoom siv muaj nyob rau hauv ntau qhov sib txawv, cov duab, thiab qib hardness, yog li nws yog ib qho tseem ceeb uas yuav tau xaiv hom khoom abrasive zoo rau koj daim ntawv thov tshwj xeeb.
