Qhov luaj li cas ntawm cov abrasive yog hais txog particle loj ntawm cov abrasive. Abrasives tuaj yeem muab faib ua plaub pawg raws li lawv qhov loj me: abrasive nplej, sib tsoo hmoov, micro hmoov thiab superfine hmoov. Ntawm lawv, cov lej loj ntawm ob pawg ntawm cov nplej zom thiab cov hmoov sib tsoo tau qhia los ntawm tus naj npawb ntawm cov meshes ib nti ntawm qhov ntev ntawm lub vijtsam, thiab lub cim yog ntxiv rau "#" cim rau sab xis sab xis ntawm tus lej. qhov loj me. Piv txwv li, 240 # txhais tau hais tias muaj 240 qhov ntawm ib nti ntawm qhov screen ntev. Qhov loj dua tus lej loj dua, qhov zoo dua cov nplej abrasive. Cov lej loj ntawm ob pawg ntawm micropowder thiab superfine hmoov yog qhia los ntawm qhov loj ntawm cov khoom, thiab lub cim yog ntxiv ib tsab ntawv "W" nyob rau hauv pem hauv ntej ntawm tus lej loj. Qee zaum nws tuaj yeem hloov mus rau hauv tus lej mesh. Piv txwv li, W20 txhais tau hais tias qhov loj ntawm cov khoom abrasive yog nyob nruab nrab ntawm 20μm thiab 14μm, uas yog tib yam li cov xov tooj 500 #.
Nyob rau hauv particle loj ntawm ntau yam abrasives, muaj coarse, nruab nrab thiab zoo hais. Qhov nruab nrab particle yog qhov loj me me hauv cov hmoov sib tsoo, thiab nws yog qhov tseem ceeb uas txiav txim siab qhov sib tsoo muaj peev xwm ntawm cov abrasive. Nws occupies ib tug loj feem nyob rau hauv lub particle loj muaj pes tsawg leeg. Kev xyaum tau ua pov thawj tias qhov sib tsoo muaj peev xwm ntawm cov hmoov av tom qab kev sib cais ntawm centrifugal yuav nce 20% piv nrog rau qhov ua ntej sib cais. Fine particles ua lub luag haujlwm me me hauv kev sib tsoo. Qhov loj me me tsis yog tsuas yog cuam tshuam rau qhov zoo ntawm kev sib tsoo workpiece, tab sis kuj txo qhov kev sib tsoo efficiency. Tus naj npawb ntawm lawv yuav tsum raug txo kom tsawg nyob rau hauv cov particle loj muaj pes tsawg leeg. Yog li ntawd, nyob rau hauv cov nqe lus ntawm kev ua tau zoo ntawm kev sib tsoo thiab kev ua hauj lwm zoo, cov abrasive hais yuav tsum tau uniform. Cov pab pawg abrasive nrog qhov loj me ntawm 12 # ~ 80 # muaj qhov loj me me thiab tsis haum rau kev ua haujlwm abrasive.
