摘要
为研究高低温老化试验对含铝温压炸药性能的影响,对样品进行了质量变化和抗压强度的研究,并采用电测法测试含铝炸药在高低温试验前后的爆速。研究结果表明:样品的质量随高低温老化时间的增加而减少;老化试验前样品的爆速为6 685 m/s,老化14 d及28 d后爆速分别为6 590 m/s和6 799 m/s,爆速并未发生显著的变化;老化试验前样品的抗压强度为5.694 MPa,老化试验14 d及28 d后未经处理样品的抗压强度为9.110 MPa和9.615 MPa,处理后的样品抗压强度为6.523 MPa和6.717 MPa,处理后的样品抗压强度低于未处理样品,对样品进行处理能显著减缓抗压强度的增加。
To study the effects of aging test at high-low temperatures on the properties of aluminized thermobaric explosive,the research of mass-change and compressive strength were conducted,and the detonation velocity of aluminized thermobaric explosive was also measured by electric probe method before and after the aging test. The results show that the quality of the samples decreases with the increase of aging time. The detonation velocity of the samples is 6 685 m / s before aging test,and is 6 590 m / s and 6 799 m / s respectively after aging 14 days and 28 days. The detonation velocity has not changed significantly. The compressive strength of the samples is 5. 694 MPa before aging test. The compressive strength of the untreated sample is 9. 110 MPa and 9. 615 MPa after aging 14 days and 28 days,and that of treated sample is 6. 523 MPa and 6. 717 MPa. The compressive strength of the treated sample is lower than that of the untreated sample. The treatment of the samples could significantly slow down the increase of the compressive strength.
