[Measurement Example] 70% Slurry - Dispersion Endpoint
We will introduce a case study examining the optimal dispersion time using a bead mill through three measurement methods.
We would like to introduce a case study conducted by Majerika Japan Co., Ltd. that explored the dispersion endpoint of a concentrated slurry of barium titanate processed with a bead mill. Using a disperser, barium titanate was dispersed in a toluene-ethanol mixed solvent, and measurements were taken at various processing times to verify the results. From measurements using a rheometer, it was estimated that the over-dispersion boundary is 25.1 mm, and sedimentation velocity distribution measurements revealed that a significant amount of coarse particles were present after 33.4 minutes. 【Case Summary】 ■ Experiment - Relaxation time was measured using pulse NMR. - Viscosity and dynamic viscoelasticity were measured using a rheometer to determine the over-dispersion boundary and conditions for good dispersibility. - Sedimentation velocity distribution was determined using a centrifugal dispersion and particle size distribution measurement device. ■ Results - The over-dispersion boundary was estimated to be 25.1 mm. - It was found that a significant amount of coarse particles were present after 33.4 minutes. *For more details, please refer to the PDF document or feel free to contact us.
