ABSTRACT:
A process for desensitizing sensitive explosives materials such as RDX or HMX involves stirring a paste of the explosives material in a liquid medium, usually water, with a wax which will soften below the safe decomposition temperature of the explosives material, heating the mixture to drive off the liquid and soften the wax which is then coated onto the explosives material as the liquid evaporates. On cooling, explosive material particles substantially entirely encapsulated in wax are obtained. When warm or after cooling, aluminum powder can be mixed with the desensitized material. As little as 1% of added wax can improve the F of I of RDX from 73 to around 100 and the wax coating is quite stable even when the explosive is pressed, e.g. when making charges.
