废旧单基药爆轰性能的实验研究

采用简单易行的见证板试验研究了单基药的爆轰性能。实验结果表明，9／7单基药自由装填可正常起爆，经钝感后爆轰感度下降，自由装填后爆轰不完全，用硝酸铵胶液填充后可改变其爆轰性能；5／7粒状单基药包覆和填充前后的爆轰性能与9／7单基药相同，22／1单基管状药填充前后爆轰性能可以由不完全变为完全；得到单基药爆轰性能可控制的结论，并且装药药型和装药量对爆轰性能也有影响。

The Experimental Study on Detonation of Wasted Single Base Propellant

Crushing wasted single-base propellant is a relatively dangerous procedure. It is necessary to solve the problem in practical production how to improve the security on the procedure and simplify the technology for treating with wasted single base propellant. The detonation occasion of wasted single base propellant was studied through witness steel-plate method,which is simple and easy. Three experimental facts: first, freely loaded 9/7 single base propellants can be ignited and exploded; passivating 9/7 single base propellant was descended in detonation sensitivity and freely loaded one can be exploded incompletely; the charge showed non-detonating or detonating reaction if no or filling in the space with gel solution of ammonium nitrate; second, if no or coating and filling, 5/7(grain shape)single base propellant was possessed similar property as 9/7 ones; third, 22/1 (pipe shape) single-base propellant showed non detonating or detonating reaction if no or filling in the space with gel solution of ammonium nitrate, proved that detonation of single base propellant was controllable and was affected by charge shape as well as charge capacity.
