Abstract:
     The non-directional industrial primacord for sympathetic detonation is composed of core thread, core chemicals and internal and external packed layers. Said invention features that the core chemicals is superfine high explosive or sensitized powder shape high explosive. When said primacord is used on-line, the size of included angle between main nd branch igniting directions is not limitted. Thus it simplifies the on-line procedures, the sympathy property is good, the sympathetic detonation has no directionality, the safety and reliability of detonation is increased. The properties of igniting, thermal-resisting, waterproof and tensile strength etc. all accord with the standards of industrial primacord.
