RDX粒度分级工艺研究

Study on RDX Granulate Stage Process

通过正交试验,给出影响RDX丙酮重结晶粒度分级工艺的主要因素。对照4类产品粒度标准,确定了该产品粒度分级的工艺条件,讨论了溶剂种类、溶液过饱和状态及溶剂蒸发速度对结晶过程的影响,分析确定了1～8类RDX粒度分级的工艺条件,并进行了优化试验。结果表明,丙酮重结晶工艺能够满足不同粒度级别RDX的生产。

The principal factors affecting the grading process for the recrystallization of RDX from acetone are given through the orthogonal test. According to the grading standard of 4 grades product, the grading process condition of product grain is determined. The oversaturated state of solution, kind and evaporation rate of solvent affecting crystallization process are described. The grading process condition of 1～8 grades RRX are analyzed and determined, and the test is optimized. The results indicate that the recrystallization process of RDX from acetone is satisfied for the produce of RDX with different grain size.
