METHOD OF MANUFACTURING CHARGES OF GEL-LIKE HYDROGEN-CONTAINING EXPLOSIVE COMPOSITION Russian patent published in 2005 - IPC

FIELD: explosives.

SUBSTANCE: invention relates to hydrogen-containing industrial blasting substances based on gel-like matrix. Manufacture of charge of explosive composition comprises preparing aqueous solution of oxidants, adding polyacrylamide to form gelated solution of oxidants, adding structure-forming agent, adding sensitizer, filling envelop, and structuring charge. Structure-forming agent is constituted by two components, interaction of which with each other leads to formation trivalent ion functioning as structure-forming agent. One of the two components is added to aqueous solution of oxidants or to gelated solution of oxidants and the other component to gelated solution of oxidants before or during addition if sensitizer. Structuring of charge is performed at 20 to 90°C.

EFFECT: simplified and improved charge manufacture technology, improved quality of charge, and stabilized physicochemical and detonation characteristics of charge.
