DISSEMINATION AND AEROSOL BEHAVIOR OF HYDROPHOBIC POWDERS.

Abstract

Data have been collected utilizing the apparatus that was built to study shock dissemination while minimizing the complication of wall collisions and agglomeration on the particle-size distribution of the recovered material. Some of the effects can be understood with shock wave theory; other effects require additional study. Confirmation has been made of the observation that the nature of the bond between particles in polycrystalline materials is important. Materials that cleave under normal circumstances have been observed to cleave in the same manner during shock comminution. Preliminary analyses and observations indicate that resorcinol is a useful simulant for CS. Various devices for producing charged clouds were fabricated and their effectiveness in enhancing the spreading of the aerosol cloud was studied. Whereas cloud spreading was observed, the small-scale laboratory equipment did not provide adequate definition. Nevertheless, data were obtained that indicate improvements in apparatus so that better data and realistic limitations can be determined for designing a full-scale or field test. (Author)
