| 摘 要： | 对3种方式敏化的乳化炸药动压作用下的减敏作用进行了研究.用测量系统捕捉该3种乳化炸药发生压力减敏作用前后水中爆炸冲击波,利用冲击波参数计算炸药的压力减敏作用程度,该值反应了压力减敏作用的大小,依据该值分析了敏化方式对压力减敏作用的影响.结果表明,敏化方式对乳化炸药动压下的减敏作用影响很大,该实验条件下分别用膨胀珍珠岩、空心玻璃微球、化学气泡敏化的乳化炸药,压力减敏作用依次减少.

| Abstract: | The desensitization of emulsion explosives sensitized by three methods and subjected by dynamic pressure was studied. Shock waves produced by the three explosives desensitized or not was caught by a measurement system, and the desensitization degree was calculated with parameters of shock waves. The influence of sensitizing methods on desensitization was analyzed by comparing the desensitization degree of them. The result shows that sensitizing methods influences desensitization of emulsion explosives subjected by dynamic pressure greatly. In the same measurement conditions, the desensitization of emulsion explosives sensitized by expanded perlite is high, that sensitized by chemical gas bubbles is low, and that sensitized by glass microballon (GMB) is between them. |
