Method for producing plastically bonded propulsion powders and explosives |
摘要 |
A method for manufacturing plastically bonded propulsive powders and explosives by means of an extruder which comprises a housing with at least one entry opening, under certain conditions a solvent supplementing opening, two co- or counterrotating screw shafts and a forming head. The method makes possible continuous production with minimal binder components of 4-6 percent. Firstly, the plastic binder in a fixed, soluble or suspended form is added by means of an entry opening for a period of time until the screws float in the plastic binder without opposing friction and without friction with the walls. The components of the propulsive powder, or correspondingly the explosive material in crystalline form, are added in steadily increasing proportions with a simultaneous reduction of the portion of the plastic binder and finally, the mixture ratio is held constant.
