METHOD OF MANUFACTURING DETONATING CORD AND METHOD OF PRODUCTION OF EXPLOSIVE SUBSTANCE FOR ITS MANUFACTURE Russian patent published in 2016 - IPC C06C5/04 

FIELD: blasting operations.

SUBSTANCE: invention relates to production of cord explosives, namely, to the manufacturing method of detonating cords. For production of detonating cord aqueous paste based on hexogene or octogene is obtained previously, by mixing the latter with water in the disclosed amounts to obtain a suspension of explosive substances particles in water and sequential addition into the produced mixture of disperser, thickener, an antifoam agent and an emulsifier in said amounts while stirring constantly. Obtained paste with moisture content from 10.0 to 15.6 wt% is extruded at a pressure of 0.15-0.20 Mpa to produce continuous core of the detonating cord with subsequent braiding the latter with polyester threads. Braided core is dried in a drying chamber at a temperature of the heat carrier of 82.1-84 °C and the protective layer on the basis of nylon is applied.

EFFECT: invention provides increase in safety of detonating cord production while ensuring high quality and reliability of the finished product.
