Txhua qhov loj me yog siv rau ntau yam kev siv hauv kev lag luam sib txawv, xws li kev txhuam kom raug, kev sib tsoo, kev txiav, thiab kev txhawb nqa sib xyaw.

2. Cov Txheej Txheem Ntsuas Qhov Loj ntawm Cov Khoom Me Me

Muaj ntau txoj kev siv dav dav rau kev ntsuas qhov loj ntawm cov hmoov pob zeb diamond:

1. Txoj Kev Siv Laser Diffraction(siv tau rau nano, micron, thiab cov khoom loj dua)
2. Kev tawg ntawm lub teeb ci ntsa iab (DLS)(feem ntau yog rau cov nanoparticles)
3. Kev Tshawb Fawb Duab Static thiab Dynamic(ntau yam micron, kuj muab cov ntaub ntawv txog cov duab ntawm cov khoom me me)
4. Cov Txheej Txheem Gravitational thiab Centrifugal Sedimentation(cov khoom me me thiab cov khoom me me)
5. Coulter Counter (Txoj Kev Tiv Thaiv Hluav Taws Xob)(cov khoom me me micron)
6. Kev Siv Tshuab Hluav Taws Xob (SEM/TEM)(kev soj ntsuam ntawm qhov ntsuas nano thiab micron)
7. Txoj Kev Ultrasonic(cov khoom me me micron)
8. Txoj Kev Nkag Tau Huab Cua(ntau yam micron, qhov nruab nrab ntawm cov khoom me me)
9. Kev Tshuaj Xyuas Sieve(feem ntau rau cov khoom me me tshaj 38 μm)

Ntawm cov no, cov txheej txheem siv feem ntau hauv Boreas ntau lawm yog kev tshuaj xyuas laser diffraction, dynamic lub teeb tawg, thiab kev tshuaj xyuas duab pom/microscopic.

3. D50 (Qhov Loj Nruab Nrab ntawm Cov Khoom Me Me) yog dab tsi?

D50hais txog lub cheeb ntawm cov khoom me me uas ncav cuag 50% ntawm qhov loj me ntawm cov khoom me me. Nws tseem hu ua qhov loj ntawm cov khoom nruab nrab.

Piv txwv li, yog tias ib qho qauv muaj D50 = 5 μm, nws txhais tau tias:

• 50% ntawm cov khoom me me loj dua 5 μm
• 50% ntawm cov khoom me me dua 5 μm

D50 yog ib qho ntawm cov cim qhia tseem ceeb tshaj plaws thiab siv dav hauv kev tsim thiab siv cov hmoov pob zeb diamond, thiab nws feem ntau siv los sawv cev rau qhov nruab nrab ntawm cov khoom me mentawm cov khoom siv.

4. D97 (Coarse Particle Indicator) yog dab tsi?

D97hais txog qhov loj ntawm cov khoom me me uas ncav cuag 97% ntawm kev faib tawm sib sau ua ke.

Qhov no txhais tau tias:

• 97% ntawm cov khoom me me dua D97
• 3% ntawm cov khoom me me loj dua D97

D97 feem ntau yog siv los ntsuam xyuas qhov kev faib tawm ntxhibntawm cov hmoov pob zeb diamond. Hauv kev xyaum ua lag luam, qee tus neeg siv khoom kuj xav tau D95, D97, lossis D98kom nruj me ntsis tswj qhov muaj cov khoom me me loj dhau.

5. Cov Txheej Txheem Tseem Ceeb hauv Kev Tshawb Fawb Txog Kev Faib Tawm Qhov Loj ntawm Cov Khoom Me Me

Feem ntau, cov kab faib tawm ntawm cov khoom me me muaj cov hauv qab no:

• Nruab Nrab (Qhov loj ntawm cov khoom me me nruab nrab):Qhov nruab nrab ntawm qhov system
• Nruab Nrab (D50):Tus nqi nruab nrab ntawm kev faib tawm ntawm cov khoom me me
• Hom (Qhov loj tshaj plaws):Qhov loj ntawm cov khoom me me uas muaj qhov zaus siab tshaj plaws
• D10:Qhov loj ntawm cov khoom me me uas ncav cuag 10% ntawm kev faib tawm sib sau ua ke
• D50:Qhov loj ntawm cov khoom me me uas ncav cuag 50% ntawm kev faib tawm sib sau ua ke
• D90:Qhov loj ntawm cov khoom me me uas ncav cuag 90% ntawm kev faib tawm sib sau ua ke

Cov kev ntsuas no ua ke muab kev nkag siab tag nrho ntawm qhov dav ntawm kev faib tawm ntawm cov khoom me me, kev sib xws, thiab kev sib xws.

6. Daim duab qhia txog qhov loj ntawm cov khoom me me (D10 / D50 / D90)

Hauv cov kab nkhaus faib tawm ntawm cov khoom me me:

• D10sawv cev rau qhov kawg zoo ntawm kev faib tawm
• D50sawv cev rau qhov nruab nrab
• D90sawv cev rau qhov kawg ntawm kev faib tawm

Kev sib raug zoo ntawm D10, D50, thiab D90 yog siv dav los ntsuam xyuas qhov kev sib npaug thiab kev ntsuas qib zoo ntawm cov hmoov pob zeb diamond.

Kev tshuaj xyuas qhov loj ntawm cov khoom me me yog qhov tseem ceeb rau kev tswj xyuas cov khoom siv hmoov pob zeb diamond. Kev ntsuas thiab kev txhais cov cim qhia xws li D10, D50, thiab D90 kom ua tau zoo tas li hauv kev txhuam, sib tsoo, thiab kev siv tshuab precision.
