Abstract
The blending of a hydrophobic silica (Cab-O-Sil ST-I) into preground resorcinol powder has been studied. Drum type and twin-shell blenders were used with and without additional energy sources to aid in deagglomeration and blending. The resultant blends were characterized by a variety of techniques. Properties studied included particle size, density, flowability, aerosolizability, and re-aerosolizability. In addition, the samples were examined using an electron microscope. The results of these experiments revealed that blending with additional energy to aid in deagglomeration produced a powder with superior properties. Pieces of hard rubber were the most successful deagglomerater in the drum blender while a high-speed liquid feed bar was most successful in the twin-shell blender. The electron micrographs revealed that all the powder was coated with the silica but that coated agglomerates were present in the blends. The additional deagglomeration energy reduced the quantity of agglomerates thereby yielding more usable powder.
