结晶粒状TNT粒度分级工艺

A Study on Size Grading Process of Crystalline TNT

采用TNT熔融过冷法(热水悬浮)结晶工艺,运用热力学原理分析了温度和搅拌速度对结晶过程的影响,通过试验确定了相应的工艺条件。结果表明,该工艺可生产出符合用户要求粒度级配的结晶状TNT产品。与溶剂结晶法相比,具有原材料成本低、无溶剂回收、不产生大气污染的优点,有很好的经济、社会效益和产业化前景。

With the help of the crystalline process of supercooled melt TNT method (hot-water suspension) and thermodynamic law, the effect of temperature and mixing speed on the crystalline process is analyzed and the process conditions are defined. The results show that the process can produce crystalline TNT products with different size grading needed for satisfying the user. In comparision with solvent crystallization, the process has the advantages of lower material costs, no solvent recovery and no atmospheric pollution and very good economic benefits and industrialization prospecfs.
