Energetic materials processing technique |
摘要 |
Energetic materials are continuously processed in a twin-screw extruder to provide safe, low-cost, high quality manufacturing of pyrotechnic compositions, gun propellants, and high explosives. The energetic materials are processed by first lacquering the binder and other soluble ingredients in a solvent. The lacquer solution is introduced into a twin-screw extruder. At least one solid reactive material ingredient, such as metal and/or oxidizer particles, is also introduced into the twin-screw extruder. The solid reactive material ingredient and the lacquer solution are mixed within the twin-screw extruder. After mixing, sufficient solvent is removed by heating or by vacuum to permit bulk granulation of the energetic material. Moist energetic material is then granulated using a remote continuous rotary granulator. The energetic material is dried to produce free-flowing granules which may be used as feedstock for further processing.
