METHOD OF PHLEGMATIZING HIGH-DENSED TWO-BASE SPHERICAL GUNPOWDER Russian patent published in 2018 - IPC C06B21/00 C06B45/28 

FIELD: chemistry.

SUBSTANCE: proposed method of phlegmatizing high-density two-base spherical gunpowder comprising the preparation of 1.5-3.5% water phlegmatizing emulsion, the preparation of a gunpowder suspension in a reactor with a stirrer, the introduction of the produced phlegmatizing emulsion in the slurry of gunpowder and the treatment of the suspension gunpowder with the phlegmatizing emulsion. At the same time, water is poured into the reactor and heated to a temperature of 80-90°C. Then gunpowder is loaded, and the slurry is mixed for 4-6 mines, the phlegmatizing emulsion at the same temperature in equal quantities is injected by 3-8 techniques with stirring every portion for 10-15 min, and after adding the last portion it is mixed for 30-60 min.

EFFECT: gunpowder retains its bulk density after phlegmatization.
