Název v původním jazyce

Thermal stability and detonation characteristics of pressed and elastic explosives on the basis of selected cyclic nitramines

Popis výsledku v původním jazyce

Bicyclo-HMX (cis-1,3,4,6-tetranitro-octahydroimidazo-[4,5-d]imidazole or BCHMX) was studied as a plastic explosive bonded with the C4 matrix and with Viton A. Also a series of nitramines namely RDX (1,3,5-trinitro-1,3,5-triazinane), HMX (1,3,5,7-tetranitro-1,3,5,7-tetrazocane) and HNIW (epsilon-2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane, epsilon-CL-20) were studied for comparison with the same types of binders. The detonation velocity, D, of all prepared mixtures was measured. Their thermal stability was determined using non-isothermal differential thermal analysis (DTA). While the C4 matrix lowers the thermal stability of the resulting explosives, Viton A enhances this stability. Approximate relationships between the peaks of exothermic decomposition and the D values were found. The detonation parameters were also calculated by means of Kamlet and Jacobs method, CHEETAH and improved EXPLO5 code for all the mixtures.
