METHOD OF PRODUCTION OF SPHERICAL POWDER FOR SHOT CARTRIDGES FOR SMOOTH-BORE SPORTS AND HUNTING WEAPONS OF 12, 16 AND 20 CALIBRE

摘要

FIELD: weapons and ammunition.;SUBSTANCE: method of production of spherical powder comprises charging water and nitrocellulose (NC) or NC to a reactor with return waste from previous operations, the previously prepared in water slurry of the combustion catalysts is poured, comprising lead (II) - copper (II) phthalate oxide, technical carbon (soot) and graphite. After that ethyl acetate and diphenylamine are poured into the reactor, and the powder lacquer is prepared, then hide glue is added and the dispersion of powder lacquer to spherical particles is carried out. Then the sodium sulphate is introduced and the process of distillation of the solvent is carried out at different temperature and time regimes in the reactor jacket.;EFFECT: invention enables to reduce the weight of the powder charge of spherical powder, to increase the speed of flight of the shot charge, to reduce the pressure on the muzzle of weapons, and to reduce fire and fury and the sound level at a shot for shot cartridges for smooth-bore weapons of 12, 16 and 20 calibres.;1 tbl, 5 ex
