METHOD OF PRODUCTION OF THE SENSITIZED EMULSION EXPLOSIVE COMPOSITION Russian patent published in 2006 - IPC C06B31/28 C06B45/08 C06B47/14 

FIELD: chemical industry; methods of production of the sensitized emulsion explosive compositions.

SUBSTANCE: the invention presents the method of production of the sensitized emulsion explosive composition, which includes preparation at the mechanical agitation of the matrix emulsion in the form of the dispersion of the water solution of salts-oxidizers in the medium of the hydrocarbon fuel containing the emulsifying agent or the emulsifying composition, intermixing of the matrix emulsion with the granules of the ammonium nitrate and sensitization by saturation with the gas bubbles with the use of the chemical reactants - the gas-producing agents from the water solution of sodium nitrite or the mixture of the water solutions of sodium nitrite and formaldehyde. The sensitization by saturation with the gas bubbles exercise by treatment of the granules of ammonium nitrate with the chemical reactants - the gas-producing agents, and after intermixing of the matrix emulsion and the treated granules of the ammonium nitrate the mass is seasoned at the temperature from 10 up to 90°C. The invention ensures intensification of the sensitization process by the gaseous saturation of the emulsion blasting explosive made on the basis of the matrix emulsion and the granules of the ammonium nitrate, and also stabilization of operational properties of the emulsion blasting explosive.

EFFECT: the invention ensures intensification of the sensitization process by the gaseous saturation of the emulsion blasting explosive made on the basis of the matrix emulsion and the granules of the ammonium nitrate, and stabilization of the operational properties of the emulsion blasting explosive.
