Highly Porous Granulated Corundum Filler of Alumina-Foam Polystyrene Mixture. Part 3. Theoretical Premises of Pelletizing Alumina-Polystyrene Foam Mixtures in a Granulator1

详细

Pelletizing of alumina-foam polystyrene mixtures is determined by presence of physicomechanical and physicochemical bonds. Decisive effects in this process are molecular and capillary forces whose value is determined by the individual properties of granulated material, layer structure, and amount of moisture. The hydrophilic nature of the test system surface and its hydrodynamic tendency towards pelletizing are established.
