摘要:
为连续化高安全性地实现锆粉的感度控制，构建了一个桌面式高通量微反应系统,并验证了利用该系统制备氢氟酸改性锆粉的可行性。通过调节流体流速比、流量及氢氟酸浓度，对改性锆粉的形貌与结构进行了研究。采用热分析法与静电火花感度测试对改性锆粉的热性能与安全性进行了分析。研究结果表明：桌面式高通量微反应系统可以实现形貌良好的锆粉改性制备，并达到每小时百克量级的处理量，改性后锆粉的表面主要由含氟氧化锆层与氢化锆层组成；氢氟酸改性锆粉的氧化速率更快，反应完全所需的时间更短，氧化增重较原料锆降低了4.0%， 50%发火能量E50由原料锆粉的1.42 mJ提升至8.98 mJ，静电火花感度明显降低。
Abstract:
To continuously and safely achieve sensitivity control of zirconium powder, a desktop high-throughput micro-reaction system was constructed, and the feasibility of using this system to prepare hydrofluoric acid modified zirconium powder has been verified. The morphology and structure of modified zirconium powder were studied by adjusting the fluid flow rate ratio, flow rate, and concentration of hydrofluoric acid. The thermal performance and safety of modified zirconium powder were analyzed using thermal analysis and electrostatic spark sensitivity testing. The research results indicate that, by using the desktop high-throughput microreaction system, zirconium powder with good morphology can be modified and prepared with a processing capacity of hundreds of grams per hour. The surface structure of the modified zirconium powder is mainly composed of fluorinated zirconia layer and zirconium hydride layer. The oxidation rate of zirconium powder modified with hydrofluoric acid is faster, the time required for complete reaction is shorter, and the oxidation weight gain reduces by 4.0% compared to the raw material. Compared to the raw zirconium powder, the 50% ignition energy (E50) increases from 1.42 mJ to 8.98 mJ, and the electrostatic spark sensitivity reduces significantly.
