Sib tsoo log yam ntxwv tsom xam: particle loj, hardness, binding tus neeg saib xyuas, thiab lwm yam.
May 20, 2024| 1. Qib nplej
Kev sib tsoo ntawm kev sib tsoo lub log feem ntau yog nyob ntawm cov khoom, yog li cov qib nplej yog ib qho tseem ceeb ntawm cov khoom sib tsoo. Cov txheej txheem ntawm kev qhia txog qib grain ntawm kev sib tsoo log yog los ntawm cov lej, xws li P60, P80, thiab lwm yam. Qhov me me ntawm cov nplej qib tus lej, cov nplej coarser, lub zog sib tsoo ntawm lub log sib tsoo, tab sis qhov zoo yog tus neeg pluag; Qhov loj ntawm cov nplej qib, qhov zoo dua cov nplej, qhov tsis muaj zog ntawm cov kev sib tsoo ntawm cov log sib tsoo, tab sis qhov zoo ntawm qhov chaw yog qhov zoo.
2. Hardness
Lub hardness ntawm lub sib tsoo log yog hais txog lub peev xwm ntawm lub sib tsoo log hais los tiv thaiv hnav thiab tawg thaum sib tsoo. Hardness yog ib qho ntawm cov yam tseem ceeb uas ua rau lub workpiece nyob rau hauv lub sib tsoo log. Lub hardness ntawm lub sib tsoo log feem ntau yog qhia los ntawm nws cov xim. Cov xim tsaus dua, qhov siab dua qhov hardness. Feem ntau hais lus, rau cov khoom uas muaj siab hardness, nws yog ib qhov tsim nyog los xaiv lub sib tsoo log nrog hardness dua, thiab vice versa, nws yog tsim nyog los xaiv ib tug sib tsoo log nrog qis hardness.
3. Binding tus neeg sawv cev
Tus neeg sawv cev khi yog cov nplaum ntawm cov khoom sib tsoo, uas cuam tshuam ncaj qha rau lub zog thiab kev ua haujlwm ntawm kev sib tsoo. Raws li cov neeg ua haujlwm sib txawv, lub log sib tsoo tuaj yeem muab faib ua peb hom: inorganic bonded sib tsoo log, organic bonded sib tsoo log thiab ceramic bonded sib tsoo log. Ntawm lawv, inorganic bonded sib tsoo log muaj lub zog siab thiab muaj zog sib txuas; cov organic sib tsoo log muaj zog me ntsis, tab sis zoo sib tsoo nyhuv; ceramic bonded sib tsoo log muaj cov yam ntxwv ntawm lub zog siab thiab kev sib tsoo siab.
Nyob rau hauv luv luv, lub sib tsoo log, raws li ib tug tseem ceeb abrasive cuab tam, plays lub luag hauj lwm tseem ceeb nyob rau hauv industrial ntau lawm. Tsuas yog los ntawm kev nkag siab txog cov yam ntxwv ntawm kev sib tsoo lub log thiab xaiv cov kev sib tsoo uas tsim nyog raws li kev xav tau tuaj yeem txhim kho kev ua haujlwm zoo thiab zoo.
