摘要:
为研究乳化炸药能发生自持燃烧的最低压力（MBP）的影响因素，通过压力容器研究6种不同配方乳化炸药的MBP。结果表明：乳化炸药中水质量分数分别为9.0%、10.0%、11.0%、15.0%时，在空气中测得乳化炸药的MBP的平均值分别为1.02、1.33、1.76 MPa和4.88 MPa，表明随着配方中水质量分数的增加，乳化炸药的MBP相应变大，即水质量分数对乳化炸药的MBP有显著影响。煤矿许用乳化炸药的试验结果表明，消焰剂含量的改变对乳化炸药的MBP无显著影响。当试验气氛改为氮气时，水质量分数为9.0%、10.0%的煤矿许用乳化炸药的MBP平均值分别为1.77、1.95 MPa，由此可见，测试气氛的改变对煤矿许用乳化炸药的MBP有一定影响，在氮气气氛中的MBP高于在空气气氛中的MBP。
Abstract:
In order to research the influencing factors on minimum burning pressure (MBP) of emulsion explosives, MBP of six kinds of emulsion explosives have been tested by pressurized vessel. Results show that the average MBP of emulsion explosives are 1.02, 1.33, 1.76 MPa and 4.88 MPa while the mass fraction of water are 9.0%, 10.0%, 11.0%, and 15.0%. It indicates that water content had a significant effect on the MBP of emulsion explosives, and the MBP of emulsion explosives increases linearly with water content. Results of coalmining permissible emulsion explosives show that the content of flame inhibitor has minor effect on the MBP of emulsion explosives. When the test atmosphere are nitrogen, the average MBP of coal-mining permissible emulsion explosives are 1.77 MPa and 1.95 MPa while the mass fraction of water are 9.0% and 10.0%. It can be seen that different test atmosphere has certain influence on the results of coal-mining permissible emulsion explosives. MBP of coal-mining permissible emulsion explosives measured in nitrogen is slightly higher than that measured in air.
