Kev ntsuas cov hmoov particle loj

Kev ntsuas cov hmoov particle loj
1. Kev soj ntsuam txoj kev: Feem ntau siv rau cov khoom siv hmoov. Thaum siv txoj kev tshuaj ntsuam xyuas los txiav txim siab cov hmoov nplej, cov khoom siv tau muab faib ua cov qauv nrog cov mesh sib txawv los txiav txim qhov feem pua ​​​​cov ntsiab lus ntawm ntau qhov ntau thiab tsawg. Piv txwv li, yog tias koj xav tau 200 mesh hmoov, koj tuaj yeem xaiv kom dhau los ntawm 150 mesh undersize thiab 250 mesh undersize; Yuav tsum tau -200 mesh hmoov, tsuas yog xaiv cov khoom hauv qab 200 mesh sieve.
2. Electron microscopy method: Rau cov hmoov uas muaj qhov me me me me thiab cov hmoov ultrafine, feem ntau siv optical microscopy method. Txoj kev siv tshuab ntsuas tshuab yog tib txoj kev uas tuaj yeem soj ntsuam cov hmoov nplej thiab ntsuas particle loj, thiab suav tias yog txoj hauv kev zoo tshaj plaws los ntawm cov neeg ua haujlwm tshawb fawb.
3, Kev cuam tshuam ntawm hmoov particle loj ntawm kev sib tov
Qhov nruab nrab particle loj ntawm cov hmoov kuj yog ib qho tseem ceeb cuam tshuam rau kev sib xyaw:
1. Kev sib xyaw cov hmoov sib xyaw nrog qhov ntau thiab tsawg tuaj yeem ua tau yooj yim sib xyaw:
Qhov no yog vim hais tias nyob rau hauv tib qho kev mob, tib qhov me me ntawm cov hmoov thaum lub sij hawm txav tsis tshua muaj kev sib cais, ua rau cov hmoov sib tov sib xyaw thiab sib xyaw.
2. Qhov sib txawv ntawm hmoov particle loj yog qhov tseem ceeb, ua rau nws nyuaj rau kev ua tiav cov hmoov sib xyaw:
Qhov no yog vim qhov me me ntawm cov hmoov me me, cov hmoov zoo dua, thiab muaj qhov nyiam rau cov hmoov kom ntab thaum sib tov. Ntawm qhov tsis sib xws, qhov loj dua qhov me me ntawm cov hmoov, cov hmoov coarser, thiab cov hmoov zoo li tog thaum sib tov. Qhov no ua rau muaj qhov tshwm sim sib cais thiab ua rau muaj kev nyuaj rau kev sib xyaw ua haujlwm.
