Originální abstrakt

For characterization of suspension, analytical centrifuge (LUMiSizer) was chosen. Suspension properties are changed owing to milling time. The higher milling time, the higher stability of dispersion. The evolution of the transmission profiles is characterized by a zone sedimentation (the particles sediment as a collective). A gradual clarification of fine fraction is observed, which is not part of the network structure. From the rheological behaviour, shear thickening and breakdown of network structure can be predicted based on the dependence of sedimentation velocity on relative centrifugal force. Further, the sedimentation behaviours were investigated as a function of solids concentration and the particle size analysis was carried out.
