针对现有乳化震源药柱作功能力低、耐压性能差、低温起爆感度低等问题,研究了耐压高威力乳化震源药柱的配方和工艺,并对产品性能进行了全面的测试分析.试验结果表明,新研制的乳化震源药柱克服了现有乳化震源药柱的不足,作功能力可达380 mL,在0.3 MPa的水压条件下,或在-40℃的低温条件下均能够正常起爆,显著拓宽了乳化炸药的应用范围.%Presently emulsion seismic charges have the defects of low strength, poor pressurization, low detonate sensitivity at low temperature. The formula and manufacture technique of a pressurization and high strength emulsion seismic charge are studied, and the properties of the new product were fully measured in this paper. The results show that the new emulsion seismic charge has overcome the shortcomings of the present emulsion seismic charge, with the strength up to 380ml. The new product can completely detonate under 0. 3MPa hydraulic pressure or at -40℃ respectively, which remarkably widen the applied field of emulsion explosives.
