FIELD: explosives.SUBSTANCE: composition includes 60-70 wt % of red phosphorus, 17-20 wt % of ammonium nitrate in the form of an aqueous solution, 4-7 wt % of powder of aluminium-magnesium alloy with dispersion of not more than 50 mcm, carbamide as a retarder in the amount of 7-10 wt % and a process additive - liquid chlorinated paraffin wax in the amount of 2-3 wt %. And the aqueous solution of the ammonium nitrate contains the following components, in wt %: ammonium nitrate or potassium nitrate 68-74, water 13-14 and sodium sulfate 13-18. The technical solution provides for higher yield of the amount of aerosol disperse phase and gaseous products of combustion and improves dispersion of soot particles providing for stability of a smoke cloud and covering ability of a created curtain.EFFECT: higher efficiency of smoke generation makes it possible to reduce smoke pot dimensions, make it compact and convenient for service use.2 cl |
