| 摘 要： | 研究乳胶基质的抗冲击波性能对于认识乳化炸药的压力减敏机理有意义。乳胶基质受到冲击波作用后，添加一定量的空心玻璃微球，将其爆炸性能与预先加入相同含量空心玻璃微球做成的乳化炸药，受到冲击波作用后的爆炸性能作了比较。结果表明乳胶基质的抗冲击波性能优于乳化炸药，并对此作了分析，认为敏化剂的加入使炸药内部具有许多微小的界面，冲击波对乳化炸药作用时很容易使界面附近的乳胶体破乳，从而使炸药爆炸性能下降。

| Abstract: | It is significative for understanding the mechanism of pressure desensitization of emulsion explosive to study the anti-shockwave performance of emulsion matrix. A certain quantity of glass microballoons (GMB) is mixed with emulsion matrix after it was subjected by shockwave, and its explosive property is compared with that of emulsion explosive bearing the same quantity of GMB and subjected by shockwaves too. It shows that the anti-shockwave performance of emulsion matrix is better than that of emulsion explosives. The analysis results indicate that there are many tiny interfaces in the explosive when sensitizers mixed with emulsion matrix, and the matrix nearby interfaces is broken easily when subjected by shock waves, thus the explosive property decreases accordingly. |
