PRODUCTION METHOD OF THE MIXED GELATINE EXPLOSIVE Russian patent published in 2017 - IPC C06B25/00 C06B25/04 C06C5/00 C06C5/04 F42B1/00 F42B3/87 F42B3/93 

FIELD: blasting.

SUBSTANCE: described the method of mixed gelatine explosive producing, based on the hexogene and a polymeric binder, including the mixing of the mixed gelatine explosive components and the formation of the explosive charge, in which prelimenary the powdered hexogene is subjected to gasification (sublimation) under the vacuum at the residual pressure of (2-5)×10^-3 Pa and at the temperature of 140-160°C, then the resulting layer of sublimated hexogene is mechanically separated from the substrate and mechanically ground upto the particles of 250-500 microns dispersion, and then the resulting product is added into a binder solution in the solvent, selected from the group of inert to hexogene - or in chloroform, or in petroleum ether, polyisobutylene is used as a binder, then the solvent is removed by evaporation until the constant weight of the product is obtained, after that the final explosive charge is formed.

EFFECT: plasticised hexogene with the reduced critical diameter is produced.
