METHOD FOR OBTAINING FILLED BALL POWDER Russian patent published in 2014 - IPC C06B25/22 C06B21/00 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to production of ball powders for small arms. A method for obtaining filled ball powder involves preparation of powder lacquer at mixing of nitrate-cellulose ingredients in water with ethyl acetate (EA), dispersion of lacquer, dehydration and removal of ethyl acetate by stripping; with that, as cellulose nitrates there used are ballistite nitroglycerine powders, tubular dinitro-diethylene g-pulvers or reusable process wastes that are first loaded to water at mixing in quantity of 30-40% of their total weight, 1.8-2.0 volumetric parts of ethyl acetate are dosed in relation to 1 weight part of the whole quantity of nitrate cellulose ingredients, temperature is increased up to 65-68°C, then, in 20-30 minutes, 0.20-0.60 weight parts of hexogene are dosed in relation to 1 weight part of total quantity of components, the mixture is mixed during 20-30 minutes at the same temperature, and the rest amount of nitrate-cellulose ingredients is added.

EFFECT: method provides for reduction of consumption as to EA and obtainment of dense filled ball powder with required physical and chemical characteristics in a wide range of particle-size distribution.
