共振声混合工艺用于火炸药实验室制备的优越性评估

对B炸药及PBX炸药实验室级别制备的共振声混合(RAM)工艺进行研究,实验量级为200 g,所用设备为2 kg级共振声混合实验样机。实验结果表明,共振声混合能够满足B炸药和PBX炸药的均匀混合,相比现有混合工艺,效率分别提升36%和114%;所得B炸药和PBX炸药产品,在外观、内部结构、密度和感度方面与现有混合工艺所得产品一致。针对火炸药实验室制备大批次、小量级的特点,共振声混合工艺具有混合速度快、工艺环节少、易清理、安全性好的优势。

Superiority Assessment of Resonance Acoustic Mixing Used for Laboratory Preparation of Propellant and Explosive

An experimental study on the process superiority of resonance acoustic mixing (RAM) was used for laboratory preparation of propellant and explosive, and the sample scale was 200 gram by 2 kilogram scale RAM experimental proprototype. The experimental results show that RAM can realize uniform mixing of Composition B and PBX explosive, and the mixing efficiency increased by 36% and 114% respectively compared with the traditional mixing process. Product properties of Composition B and PBX explosive including appearance, internal structure, density and sensitivity are almost the same for RAM and traditional mixing process. In view of the characteristics of large quantities, small scale prepared in the laboratory preparation of propellant and explosive, the RAM has the advantages of faster mixing speed, less process links, easy cleaning, and safer process.
