METHOD OF PRODUCING MONO-BASE PELLET POWDER FOR SMALL ARMS Russian patent published in 2016 - IPC C06B21/00 C06B25/18 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to production of monobasic pellet powders for small arms. Powder elements consisting of nitrocellulose, diphenylamine, graphite and moisture, are phlegmatised in a phlegmatisation apparatus phlegmatising emulsion. Water is poured into phlegmatisation apparatus, in turbulent mixing conditions pellet powder is loaded and mixture is heated to temperature of 75-80 °C. Upon achieving temperature of mixture, skin glue and phlegmatizing agent consisting of dinitrotoluene and centralite 1 are added to phlegmatisation apparatus. For 10-15 minutes mixture is heated to temperature of 94-98 °C. Powder is phlegmatised for 40-60 minutes, after which powder is washed.

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