Abstract

A method for phlegmatizing an explosive in an aqueous suspension including a dispersed phlegmatizing agent. The phlegmatizing agent is deposited on a surface of the explosive at low temperature utilizing opposite electric charges of the phlegmatizing agent and the explosive. Also a device and a phlegmatized explosive.

Abstract

The present invention relates to a method for phlegmatising an explosive (21) in an aqueous suspension (20), containing a dispersion solution (24) and a dispersion decomposer (23). It is characterised in that the phlegmatising agent (25) is deposited on the surface of the explosive (21) at low temperature by means of their opposite electric charges. The invention also relates to a device and an explosive phlegmatised by means of said method and device.

Abstract

The present invention relates to a method of producing propellant charges (2) of multi-perforated stick propellant with maximized charge weights for sub- calibre, armour-piercing, high-velocity projectiles (3) , which are provided, for example, with six to eight, fixed stabilizing fins (5-10) . The invention also encompasses a multi-perforated stick propellant (11-12) intended for this purpose and a propellant charge produced from multi-perforated stick propellant according to the methods.
