正交试验法研究DNAN基熔铸炸药的装药工艺

Charge Process of DNAN Based Melt Cast Explosive by Orthogonal Experiments

以典型的2,4-二硝基苯甲醚(DNAN)基热塑态熔铸炸药——MX-2为研究对象,采用正交试验法对影响MX-2炸药装药平均密度、密度差以及组分均匀性的主要工艺因素及其影响显著性进行了研究。结果表明,药浆温度、真空处理时间和真空度对装药质量有着重要影响,影响的显著性顺序为:真空处理时间>真空度>药浆温度。最佳装药工艺条件为:真空处理时间15 min,真空度-0.090 MPa,药浆温度95℃。

Using a typical 2,4-dimitroanisole（ DNAN）based thermoplastic melt-cast explosive MX-2 the influence of main process factors and important degree of various factors on mean charge density,density difference and ingredient uniformity of the MX-2 were investigated by orthogonal experiments. Results show that the slurry temperature,vacuum pumping time and vacuum are ma-jor factors influencing the charge quality. The order of significant influence is：vacuum treatment time 〉 vacuum degree〉 slurry temperature. The optimal conditions of charge process are as follows：vacuum treatment time 15 min,the vacuum degree-0. 090 MPa and the slurry temperature 95 ℃.
