Abstract

A novel technology for powder dispersion and surface modification was studied by experiment in this paper. In the process, powders are dispersed by the nozzle and the atomized modifying agent is sprayed into the dispersed particles and coated on the surface at the same time. Silica, mica and talc powders were dispersed and modified by this technology, the performance of powder dispersion is evaluated by the scanning electron microscope (SEM), and the performance of surface modification is evaluated in advance by the viscosity of powder-paraffin suspension. In experiment, the modified silica was filled in the polypropylene (PP), the impact fractographs, notched impact and tensile properties of the PP composites were studied, the results indicate that the developed technology is effective for powders dispersion and surface modification.
