Sedimentation Measurements

Sedimentation measurements are used to observe precipitation measurements for various batches of finely dispersed powders. This measurement method can be used to evaluate the sedimentation, wetting, and dispersibility of powders.

  • Wetting property using initial dispersibility of powder:
Use the sedimentation jig to measure sedimentation. Dip the jig into the liquid and place the powder sample into the liquid. Over time, the powder sample is precipitated and the sedimentation rate can be checked using the weight of the powder accumulated in the jig. The faster the sedimentation speed, the better the wettability.
 
  • Dispersion stability evaluation of powder:
The same jig as above can be used to evaluate the dispersion stability of the powder. The powder particles are put in the liquid in advance and thoroughly mixed into the liquid using the Stirrer built into the equipment. After the stirrer operation, the dispersion stability can be checked by checking the sedimentation speed of the powder. The slower the settling rate, the better the dispersion stability.
