摘要
以有序结构叠氮化铜纳米线阵列为研究对象,结合实验现象开展原位反应机理分析,在此基础上,首次建立了叠氮化铜纳米线阵列三维稳态气固未反应核数学模型;通过对比反应时间对叠氮化程度的影响规律,验证反应动力学模型的正确性。研究结果表明,叠氮化反应程度随反应时间增加而增加,反应时间大于15h后,反应速率减缓。反应时间与叠氮化铜纳米线阵列叠氮化程度较好地符合S型函数DoseResp模型,模拟仿真结果可为叠氮化铜纳米线阵列工艺参数优化及爆炸性能研究提供数据支撑。
Copper azide nanowires array with orderd structure were taken as the research object,and the in-situ reaction mechanism was studied in combination with the experimental phenomenon.On this basis,a three-dimension gas-solid shrinking core model was established.The effect of reaction time on the azide degree was compared to verify the correctness of the reaction kinetics.The results show that the azide degree is increased with the increase of reaction time,and the reaction rate is slowed down after 15 hours.The relationship between reaction time and reaction degree is consistent with DoseResp function.The simulation results can provide data support for optimizing process parameters and explosion performance study of copper azide nanowires array.
