| 摘 要： | 为了回收RDX/Al/AP/HTPB炸药中的高氯酸铵(AP),通过Design Expert 8.0软件进行了响应面实验设计,得出了该工艺的提取率模型,研究了提取时间、超声功率、表面活性剂质量分数等因素对AP提取过程的影响。分析数据得出AP提取工艺的最佳参数,并对其进行了实验验证。结果表明,二次回归模型的拟合方程为:Y=89.82+3.10A+2.65B+0.33C-0.25AB-0.45AC-0.15BC-0.06A2-1.31B2-0.26C2。各因素对提取率的影响程度由大到小为:提取时间、超声功率、表面活性剂质量分数。优化的工艺参数为:提取时间44 min,超声功率960W,表面活性剂质量分数1.7%,此时AP的提取率达90%以上。

| Abstract: | In order to recycle ammonium perchlorate (AP) from the RDX/Al/AP/HTPB explosive, software Design Expert 8. 0 was used to design response surface test. Recovery ratio model was fitted. Influence of various factors, such as leaching time, ultrasonic power and surfactant mass fraction, on extraction of AP were also analyzed. Optimum parameters of AP extraction process were obtained by data analysis. Quadratic fitting model is Y=89. 82+3. 1A+2. 65B+0. 33C-0. 25AB-0. 45AC-0. 15BC-0. 06A2 -1. 31B2 -0. 26C2 . Significance of each factor on extraction rate in order is leaching time, ultrasonic power, surfactant mass fraction. Optimization of process conditions are leaching time 44 min, ultrasonic power 960 W, and surfactant mass fraction 1. 7%. Extraction rate of AP is above 90%. |
