MANUFACTURING METHOD OF PYROTECHNIC CHARGES, AND PYROTECHNIC COMPOSITION FOR CHARGES OF THERMAL DESTRUCTION OF SOLID BODIES Russian patent published in 2015 - IPC E21C37/16 C06B33/00 

FIELD: construction.

SUBSTANCE: manufacturing method of pyrotechnic charges for thermal destruction of solid bodies involves mixing operations of powders of aluminium-magnesium alloy, iron oxide or iron scale and an organic flammable binding agent, and further compaction of the mixture. Pyrotechnic mixture that contains a solution of colophony in bobbin oil as an organic flammable binding agent is pre-granulated with size of granules of 2-3 mm; after that, it is compacted by means of vibrations subsequently in portions in the volume of one fourth -half of the charge, during 2-3 minutes each. Pyrotechnic composition for charges of thermal destruction of solid bodies is made of a mixture at the following component ratio (wt %): powder of aluminium-magnesium alloy 29-36; iron scale or iron oxide 62-67; solution of colophony in bobbin oil 2-4.

EFFECT: invention allows more effective localised destruction of solid bodies due to manufacture of independent and flexible charges from an optimised pyrotechnic composition.
