Detonation Velocity and Detonation Pressure of RDX Miztures with Sodium Chloride

Analysis of works dealing with metal working by explosion shows, that the range of detonation pressure of explosives charges for this purpose is P=0.3–10 GPa. Experimental investigations show that RDX mixtures with sodium chloride meet the requirement. Heat of explosion of such mixture, velocity and pressure of detonation can be changed in a wide range. These mixtures are applied for measuring of minimal initiation pressure of dangerously objects in the practice of industrial safety investigations. Computer codes for calculation of detonation velocity and pressure are unsuitable for mixtures containing less than 30% of explosive material. The goal of this paper is elaboration of a method of calculation of detonation parameters of RDX/inert additives mixtures and estimation of its efficiency. The results of experimental measurement of detonation parameters of them were taken into account. Experimental results of a detonation pressure measurement are compared with computation ones at constant and at variable vs. density of explosive polytropic exponent. The good agreement turns out in a second case. Detonation of RDX/inert powder mixtures is available as particles of additives have no time to warm up in detonation wave. However at igniting of such mixtures inert particles warm up and burning process damps. Such peculiarity, ability to detonation and inability to burning and therefore to deflagration to detonation transition, excludes its accidental explosion at use.
