FIELD: process engineering.SUBSTANCE: invention relates to throwing charges. Modular charge comprises unplasticised cellulose nitrates (CN), water soluble polymer binder, diphenylamine (DPA) and, possibly, energy-saturated bilk (based on nitroglycerine, highly etherified CN, DPA and centralite II) and active filler of high explosives and/or high explosive powders and/or powder crumb. Proposed method comprises making of binder solution, DGA solution of ethyl alcohol and, possibly, active filler. Said components are mixed using the energy saturated bulk or without it to produce press-bulk. Moisture content of the latter is decreased by drying or by direct removal of excess liquid phase therefrom at pelletising in pelletiser. Charges from dried or pelletised press-bulk are compacted by keeping at pressure with simultaneous discharge of excess liquid phase from the mould. After two-stage moisture removal, block articles are subjected to surface coating with thin ply of energy active material of diluted CN solution in organic solvents.EFFECT: higher physical and chemical, ballistic and operating characteristics.12 cl, 3 tbl |
