用DSC—TG—FTIR(热红)联用研究了RDX/AP,HMx/AP,RDx/HMx和RDX/HMX/AP混合体系的热分解,测定和比较了它们的热分析特征量和分解气相产物。结果表明,AP与RDX和HMX之间存在强烈的相互作用,尤其是与后者的作用更强烈。在AP(不含碳)分解的温度区间,混合体系的分解也出现CO、CO2和CH2O等碳氧化物,说明体系中RDX和HMX分解的部分产物或残渣与AP同时分解。 相似文献

Intragranular defects inside RDX/HMX were studied by optical microscopy with matching refractive (OMS), sink‐float method (SFM), and micro‐focus CT (μCT) techniques. OMS results revealed the phenomenon that RDX/HMX had more defects and cracks than RS‐RDX/RS‐HMX. μCT results indicated that RDX/HMX had more defects with larger volume than RS‐RDX/RS‐HMX. The gap test showed that critical shock pressure/gap thickness was 6.4 GPa/19.4 mm for PBX based on RDX, while they were 7.5 GPa/17.5 mm and 8.6 GPa/16.2 mm for PBX based on M‐RDX and RS‐RDX, respectively. Meanwhile, an analysis of the relationship between defects inside RDX/HMX crystal and shock sensitivity was made. Finally, the shock pressure response under impact loading was investigated by discrete element method. 相似文献

Simulated wastewater of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) and octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) was treated under anaerobic conditions with co-substrates such as ammonium chloride, dex-trose, sodium acetic, sodium nitrate and sulfate. The results showed that with nitrogen compounds such as ammonium chloride added as co-substrate, no significant change was observed, indicating that the molar ratio of N/C for RDX and HMX is sufficient for biodegradation. With the addition of dextrose and acetate to the system, biodegradation efficiency was enhanced greatly. For example, with dextrose as the co-substrate, degradation efficiency of 99.1%and 98.5%was achieved for RDX and HMX, respectively, after treatment for 7 days. When so-dium acetic was used as the co-substrate, the enhancement of degradation percentage was similar, but was not as high as that with dextrose, indicating the selectivity of RDX and HMX to co-substrate during anaerobic degrada-tion. With sodium nitrate as the co-substrate, the degradation efficiency of RDX or HMX decreased with the increase of salt concentration. Sodium sulfate has no significant effect on the biodegradation of RDX and HMX. A wel-selected co-substrate should be employed in applications for degradation of RDX and HMX wastewaters. 相似文献

5,5′-偶氮四唑过渡金属含能配合物对RDX和HMX热分解行为的影响 总被引:1,自引:0,他引:1
用DSC研究了5种5,5′-偶氮四唑过渡金属配合物MATZ(H2O)n(M=Mn,Ni,Zn,n=6;M=Co,Pb,n=3;ATZ=5,5′-偶氮四唑离子)对RDX和HMX热分解行为的影响。用分解峰温、热爆炸临界温度等特征参数评价了含配合物的二元混合物与纯组分的热分解行为。结果表明,配合物对RDX的影响大于对HMX的。含配合物的二元混合物的热分解行为与纯组分的热分解行为类似,配合物的分解影响了RDX和HMX的热分解特征参数。 相似文献

超细HMX的表面能研究 总被引:2,自引:0,他引:2
用DCAT21型表面/界面张力仪测量了原料HMX(奥克托今,45μm~62μm)、超细HMX(0.2μm~1.7μm)和黏结剂FPM2602的接触角,并计算出它们的表面能。分析了HMX随粒径变化时其表面能的变化规律和黏结剂包覆超细HMX表面能的基本要求。结果表明,细化HMX表面能随粒径的减小有增加的趋势;黏结剂的表面能低于超细HMX的表面能,理论和实验均证明黏结剂FPM2602能包覆于超细HMX的表面。 相似文献
