摘要:
为探索工艺参数对球扁药脱硝反应的影响规律，利用响应面法的Box-Behnken设计优化球扁药脱硝工艺。在单因素实验基础上，分析了脱硝剂质量分数、反应温度和反应时间对梯度硝基球扁药爆热的影响；利用显微拉曼技术研究了梯度硝基球扁药的微观结构组成；并采用密闭爆发器实验对脱硝前、后球扁药的定容燃烧性能进行研究。单因素实验和响应面法优化结果均表明，影响梯度硝基球扁药性能的工艺参数主次顺序为：反应温度、反应时间、脱硝剂质量分数。通过响应面法建立的脱硝工艺参数与梯度硝基球扁药爆热之间的模型相关系数为0.978 5，且实验验证所得爆热与响应面模型预测的爆热基本吻合，表明优化得到的响应面模型具有可靠性和有效性。拉曼表征结果表明，梯度硝基球扁药表层硝酸酯基的分布由表及里呈梯度递增趋势。通过调节工艺参数，使得梯度硝基球扁药的爆热和燃烧渐增性大范围可控，为梯度硝基球扁药性能的精准调控提供了技术和理论支持。
Abstract:
To explore the influence of process parameters on the denitration reaction of spherical gun propellant, Box-Behnken response surface methodology was used to optimize the denitration process of spherical gun propellant. On the basis of single factor experiments, the effects of denitration agent concentration, reaction temperature, and reaction time on explosion heat of nitro gradiently distributed spherical gun propellant were analyzed. The microstructure composition of nitro gradiently distributed spherical gun propellant was studied using micro Raman technology. The constant-volume combustion performance of nitro gradiently distributed spherical gun propellant before and after denitriation was investigated using a closed bomb test. The results of single-factor experiments and response surface methodology optimization both indicate that the primary and secondary process parameters affecting the performance of nitro gradiently distributed spherical gun propellant are reaction temperature, reaction time, and denitration agent concentration. The correlation coefficient between denitration process parameters established by response surface methodology and the explosion heat of nitro gradiently distributed spherical gun propellant is 0.978 5. The explosion heat obtained from experiment is basically consistent with the explosion heat predicted by the response surface model, indicating that the optimized response surface model is reliable and effective. Raman characterization results indicate that the distribution of nitrate ester groups on the surface of nitro gradiently distri-buted spherical gun propellant shows an increasing gradient from the surface to the interior. After adjusting the process parameters, the explosive heat and combustion progressivity of nitro gradiently distributed spherical gun propellant could be controlled over a large range. It provids technical and theoretical supports for the precise control of the performance of nitro gradiently distributed spherical gun propellant.
