FIELD: chemistry; explosive or thermal compositions.
SUBSTANCE: invention relates to production of powder and can be used for propellant charges for cartridges of small arms, including for sporting and hunting cartridges and traumatic weapons. Porous pyroxylin powder for propellant charges to cartridges of small arms of civil purpose contains cellulose nitrates, diphenylamine, water, graphite, residual alcohol-ether solvent. Additionally, it contains residual acetone and camphor at the following ratio of components, wt.%: diphenylamine 0.7–2.0; alcohol-ether solvent – not more than 0.4; acetone – not more than 0.4; water 1.0–1.6; graphite – not more than 0.7; camphor – not more than 1.0; cellulose nitrates – balance. Bulk density of powder is 0.510–0.790 kg/dm3.
EFFECT: providing the required ballistic characteristics of the porous pyroxylin powder for civil purposes.
