采用微团化动态结晶技术对原料HMX进行超细化,针对后处理过程HMX晶体长大和团聚的突出问题,制定不同干燥条件进行分析研究。实验得到冷冻干燥和加入表面活性剂PVP可有效地抑制晶体长大和团聚。最后进行放大实验,优化干燥条件和调节PVP的加入量,制得了0.4~1.6μm的HMX超细炸药,每次处理300 g HMX,效率最高。

Ultrafine HMX was prepared by the atomizing kinetic crystal method. Aiming at the prominant problems that HMX crystals would grow and reunite during the post-treatment process, different drying conditions were formulated, analyzed and stud-ied. In the experiment, it is found that freeze drying and adding surfactant PVP could effectively inhibit crystal growth and reunion. At last, the expanding process was carried out and 0.4~1.6 μm particles of ultrafine explosive HMX were prepared by optimizing drying conditions and adjusting the addition amount of PVP, and the efficiency could be the highest when 300 g of HMX was dried each time.
