摘要
Industrial TiO2, microcryst. cellulose, dehydrated Al-Mg silicate, tarflen, polystyrene and PVC as well as wheat starch, potato starch and corn flour were studied for flowability (flow function) and internal friction (IF) using the Jenike device under consolidation stress 4-10 kPa. The wheat starch, corn flour and PVC were found to be free or easily flowing materials (max. IF angle 50 degrees) while the remaining industrial powders and potato starch were found to be cohesive ones (max. IF angle 30 degrees). Remarkable oscillations were observed for corn flour and wheat starch during the direct shear test.
