PETN and HNS ultrafine powders were prepared by bead-milling method, and HNS ultrafine powders were prepared by recrystallization. These ultrafine powders were used as initiating explosives for slapper detonator and their minimum firing energy was less than 1J.
A synthetic method of explosive is introduced. 1 (2′,4′ Dinitrophenyl)benzotriazole is prepared by the condensation reaction of benzotriazole and 2,4 dinitrofluorobenzene. Then through the nitration process, 5,7 dinitro 1 (2′,4′ dinitrophenyl) benzotriazole is systhesised.
When the electrical exploding semi-conductor bridge(SCB)is used to initiate the HE, the safety properties are better and required energies are smaller than the HE initiated by electrical exploding conductor bridge because the special electrical performances of semi-conductor materials.
The interaction of an SR beam with a cylindrical charge of a detonating explosive is described within the framework of a one-dimensional hydrodynamic model.
The "collapsing air gap" method has been used to investigate the development and limiting parameters of the Mach reflection of a conical convergent shock in plexiglas cylinders arranged along the axis of a detonating explosive charge.
Articles consisting of a charge of detonating explosive without means of initiation.
Articles containing a charge of a detonating explosive in a casing of fiberboard, plastics, metal or other material.
Such an explosive may react as a deflagrating or as a detonating explosive.
