Process for the manufacture without solvent of preformed porous propellant charges and propellant charges thus produced.

摘要

P Process for the production of preformed porous propellant charges, characterized in that, without the addition of a solvent or gelling agent, a water-soluble pore-blowing agent is mixed with a solvent-free powder known per se, kneading is carried out and The mixture is pelletized in the usual manner, the propellent mixture thus obtained is extruded in the desired form, the porogenic agent of the extruded propellant charges is eluted with water and the porous propellant charges are dried. BR/ Application: for example to propulsive charges for arrow shells. / P
