METHOD OF PRODUCING DOUBLE-BASE PELLET POWDER FOR SMALL ARMS Russian patent published in 2016 - IPC C06B21/00 C06B25/24 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to production of double-base pellet powder for small arms. Spherical elements consisting of nitrocellulose, nitroglycerine, diphenylamine, dinitrotoluene, centralite II, graphite and moisture, are phlegmatised in a phlegmatisation apparatus of phlegmatising emulsion. Water is poured into phlegmatisation apparatus, pellet powder is loaded and mixture is heated to temperature of 50-55 °C. Upon achieving temperature of mixture in phlegmatisation apparatus, skin glue and centralite I are added and for 10-15 minutes mixture is heated to temperature of 76-86 °C. Powder is phlegmatised for 40-60 minutes, after which powder is washed.

EFFECT: method provides complete precipitation of phlegmatisers on surface of powder elements during phlegmatisation of powder improves stability of ballistic characteristics of double-base pellet powder.
