FIELD: chemistry.SUBSTANCE: invention relates to field of spherical gun powders (SGP) obtaining for small arms, in particular, for smooth-bore shotguns. Method includes mixing of components, preparation of gunpowder varnish in ethylacetate, dispersion in presence of glue, distillation of ethylacetate and drying. Gunpowder, which contains mixture of pyroxyline with nitrogen oxide content 205.0-210.5 ml NO/g, and pyroxiline with nitrogen oxide content 205.0-210.5 ml NO/g, diphenylamine, ethylacetate, with humidity 6-10 wt %, size of gun powder elements 0.7-0.4 mm, with bulk density 0.60-0.80 kg/dm, is processed in revolving polished drum with graphite of C-1 mark together with water, after that, petrolatum is introduced and mixed. After that, gunpowder is dried.EFFECT: invention ensures obtaining SGP with evenly dispersed porosity, increase of moisture resistance of gunpowder, applied for equipment of hunting shotguns and sport cartridges for smooth bore guns.1 tbl, 5 ex |
