Abstract
The extrusion of nitrocellulose/nitroglycerine/nitroguanidine explosives employs a suspension of powder or granules in water and is effected into air or water. Extrusion of complicated sections is possible. Ideally grains of approx. 1 mm. are employed and fine powders may be first treated by heating with a nitrocellulose solvent having limited solubility in water, e.g. methylethylketone or ethyl acetate. Process is used in the mfr. of explosive materials, the use of aq. suspensions throughout reduces explosion hazards during mfr. and produces solvent-free material of superior ballistic properties, more economically than conventional methods.
