摘　　要：采用Brookhaven 90 Plus型激光粒度分析仪,对超细PETN样品的粒度及粒度分布进行了测试,研究了测试样品制备过程中的影响因素。通过实验得出测试样品制备的最佳工艺条件为：以蒸馏水为悬浮载体,六偏磷酸钠为最佳分散剂,最优间隔振荡时间80s,最适合的质量浓度是220-300μg/mL。将最佳条件下的测试结果与样品的SEM照片进行对比,二者吻合较好。此方法可以推广到其他超细炸药的测定。The particle size and particle size distribution analysis of ultrafine PETN was carried out by Brookhaven 90 Plus laser particle size analyzer. Effect factors in preparation of samples for particle size and particle size distribution analysis were studied, and the optimum condition was obtained. Results indicate that using distilled water as the suspension agent, sodium hexametaphosphate as the best dispersion, the condition of supersonic is intermission vibrate for 80 seconds and the suitable test concentration is 220 to 300μg/mL. The test results in the optimum conditions agreed well with the SEM photograph of the sample. This test method can be used for other ultrafine explosive.
