Powder density (specific gravity) plays lub luag haujlwm tseem ceeb hauv kev sib xyaw hmoov

Powder density (specific gravity) plays lub luag haujlwm tseem ceeb hauv kev sib xyaw hmoov. Qhov me me qhov sib txawv ntawm cov hmoov ntom ntom, qhov yooj yim dua rau cov hmoov sib xyaw ua ke, thaum qhov loj dua qhov sib txawv ntawm cov hmoov ntom ntom, qhov nyuaj dua rau cov hmoov sib tov. Hmoov ntom kuj muaj kev cuam tshuam rau cov hmoov flowability, thiab nyob rau hauv tib yam kev mob, lub siab dua cov hmoov ntom, qhov zoo dua qhov flowability.
1, Lub tswv yim ntawm hmoov ceev (qhov tshwj xeeb lub ntiajteb txawj nqus)
Qhov ntom ntawm hmoov yog hais txog qhov loj ntawm cov hmoov hauv ib chav tsev ntim. Hauv kev siv cov tswv yim, qhov ntom ntawm cov hmoov tuaj yeem muab faib ua xoob ntom ntom thiab compacted ntom.
1. Loose density: yog hais txog qhov sib piv ntawm qhov loj thiab ntim ntawm cov hmoov nplej uas muaj nyob hauv ib lub ntim me me, qhov twg cov hmoov yog xoob khi.
2. Vibration ntom ntom: yog hais txog qhov sib piv ntawm qhov loj rau ntim ntawm cov hmoov uas tau rov vibrated thiab compacted ib chav tsev ntim, nrog rau cov hmoov nyob rau hauv ib tug kuj nruj kev sib raug zoo lub xeev. Feem ntau, qhov compacted ceev yog 1.2-1.3 npaug ntawm qhov ntom ntom.
3. Qhov tseeb qhov ceev ntawm cov khoom nyob rau hauv lub thoob: Nyob rau hauv lub tswv yim daim ntawv thov, cov kev ceev ceev ntawm cov hmoov nyob rau hauv lub mixing khoom thoob yog nyob rau hauv lub xoob ntom ntom thiab compacted ntom. Yog li ntawd, thaum xam lub peev xwm thauj khoom ntawm cov cuab yeej sib xyaw, qhov cuam tshuam ntawm ob qhov ntom ntom no yuav tsum tau txiav txim siab.
4. Kev sib raug zoo ntawm cov hmoov tshwj xeeb lub ntiajteb txawj nqus thiab hmoov ntom ntom:
Qhov ntom yog qhov piv ntawm cov hmoov loj rau ntim (qhov kev ntsuas ntawm qhov loj yog qhov nyuaj heev); Qhov tshwj xeeb lub ntiajteb txawj nqus yog qhov piv ntawm hmoov hnyav rau ntim (txoj kev ntsuas qhov hnyav yog qhov yooj yim heev). Qhov tshwj xeeb lub ntiajteb txawj nqus thiab qhov ntom ntom ntawm cov hmoov yuav luag sib npaug hauv thaj chaw qis qis ze ntawm ntug dej hiav txwv. Yog li ntawd, peb feem ntau siv qhov hnyav rau kwv yees qhov ceev.
