I. Sphererity -} tsav sib tsoo tshuab rau cov hmoov pleev xim
Qhov ntsuas kev kub voos: 95 Zirconia hlaws ua tiav txoj kev sib tw kam<1%, forming near-perfect spherical structures with smooth surfaces (Ra surface roughness <0.2μm). This geometry differs fundamentally from irregular abrasives (e.g., quartz sand, which has angular edges).
Kev zoo dua: Cov hlaws dai nthuav dav qis dua Rolling tsis kam (txhuam coefficient μ}}}
Ii. Kev txhim kho tseem ceeb hauv cov hmoov pleev xim kom zoo nkauj
Uniform particle loj faib
Kheej kheej hlaws dai tsim cov av me me txuas ntxiv (D90-D10<15μm for talc powder, vs. 30-50μm with conventional media).
Case study: In silica-based face powder production, using zirconia beads reduces the proportion of coarse particles (>50μm) txij li 8% rau<1%, while increasing the fine particle fraction (<5μm) from 25% to 45%.
Txhim Kho Cov Hmoov Kob
Spherical sib tsoo kev txiav txim siab ua yuam kev nrog ntau cov duab, txo kev cuam tshuam nrog kev sib txhuam. Kev ntsuam xyuas flowability qhia:
Cov tsev muaj tsawg dua los ntawm 28% (Angular hais) txog 15% (kheej kheej), ntsib tus qauv ntws zoo tagnrho (<20%).
Hausner piv cov tee tawm ntawm 1.45 rau 1.2, qhia tau txhim kho kom loj dua rau cov hmoov ua hmoov.
Txhim kho daim tawv nqaij nplaum thiab smoothness
Spherically av pigments muaj smoother qhov chaw (ntsuas los ntawm AFM nrog kev ntxhib ntxoo txo los ntawm 60%), ua rau:
Lub teeb kev nthuav dav ntau dua (kev sib txawv<5% vs. 15% with irregular particles).
Zoo dua kev ua kom tawv nqaij, txo fallout - kev ntsuam xyuas qhia foundation hmoov nplaum nce los ntawm daim kab xev kev sim.
