Preliminary study on several plastic bonded explosives based on cyclic nitramines

Popis výsledku v původním jazyce

A series of plastic explosives were prepd. with binders based on polyisobutylene (PIB), acrylonitrile-butadiene rubber (ABR), viton A and using RDX beta-HMX, BCHMX and epsilon-HNIW. Pentaerythritol tetranitrate (PETN) and 3 putty-plastic explosives basedon PETN were used for comparison. Detonation velocities, D, impact and friction sensitivities of these explosives were detd. The relations of the friction sensitivity to impact sensitivity, and of both these sensitivities to the D2 term indicate that the mechanism of transfer of the friction force to the reaction center of nitramine mol. should be different from that of impact energy transfer. Mutual comparison of the friction and impact reactivities of tech.-grade and of "reduced sensitivity" grade ofepsilon-HNIW led to the finding that the impact sensitivity distinctly depends on the crystal quality of nitramines, while in the case of friction sensitivity this dependence should not so pronounced.
