摘要:
文章对井下装药器散装乳化炸药低温敏化工艺进行研究，通过优化乳胶基质配方，选择多功能复合敏化剂，采用管式混合器进行化学敏化，用光学显微镜观察敏化后乳化炸药微观形态及气泡分布情况，并测试乳化炸药的爆炸性能。研究结果显示：配方中加入0.5%的凡士林能显著提高乳胶基质的贮存期稳定性，且满足快速发泡要求，乳化炸药密度为1.0~1.2g/cm3，气泡密度在107~109个/cm3之间，气泡分布及大小均匀；炸药具有雷管感度，爆炸性能优良，达到或超过GB18095—2000中露天乳化炸药要求。
Abstract:
It researched the low-temperature sensitization technology of bulk emulsion explosive used for underground loading vessel. By optimizing the formula of emulsion matrix, a multifunctional compound sensitizer was selected. The tubular static mixer was used for chemical sensitization. The micromorphology and distribution of air bubbles of sensitized emulsion explosive were observed by an optical microscope. The explosion properties were also measured. The results show that the addition of 0.5% Vaseline could significantly improve the storage stability of the emulsion matrix and meet the rapid foaming requirements. The explosive exhibits a desired density of 1.0~1.2g/cm3 and a uniform air bubbles distribution in density of 107~109/cm3. Its excellent explosive performances with detonators sensitivity meet or surpass the requirements of openair emulsion explosives in GB18095—2000.
