Abstract
The article describes a possible way of introducing nanoscale powders into energy-saturated heterogeneous composite materials (ECM). By the example of polydispersed nanoscale carbon, the main well-known methods for introducing nanoscale components into dispersed and high-viscosity colloidal systems have been studied, their effectiveness has been evaluated, and limitations have been revealed. The main influencing factors on the uniform distribution of nanoscale components in the volume of the composite material and the ways of leveling their influence have beenfound. A technological scheme has been proposed for increasing the distribution uniformity of nanoscale components due to their preliminary deposition on the surface of the material prevailing in quantity of dispersed component while limiting the growth of its specific surface as a method of further reduction of the viscosity of the energy-saturated heterogeneous composite material at the stage of mixing its liquid and solid phases.
The rate of change of the form factor, specific surface and distribution of the nanoscale diamond-containing additive over the particle surface of ammonium salt of perchloric acid has been studied depending on the modes of mixing the components in a gravity mixer. Acceptable technological mixing modes have been found.
The main tasks of further study of phenomena arising at the phase boundary when introducing nanoscale additives into the dispersed medium of ECM have been determined.
