自敏化硝酸铵安全性能及其应用研究

本文在研究表面活性理论基础上,应用真空析晶技术制得了颗粒内部含有大量微气孔的硝酸铵,这种硝酸铵易粉碎、比表面大、具有自敏化的特征,其起爆感度增加.文中对自敏化硝酸铵的机械感度、热感度、静电感度、雷管感度等进行了全面的研究.结果表明,自敏化硝酸铵的雷管感度在工业生产过程中是可以控制的,用自敏化硝酸铵代替普通硝酸铵可以制得性能优良的硝铵炸药.

A STUDY ON THE SAFETY AND APPLICATION OF SELF-SENSITIVE AMMONIUM NITRATE

Based on a study of surface activity theory, vacuum crystallization technique is applied to form an ammonium nitrate (AN) containing micro holes in its crystals The product is characterized by its ease of pulverization, having large surface area and self sensitivity, as well as of increased detonating sensitivity Its mechanical sensitivity, heat sensitivity, electric sensitivity and cap sensitivity are also studied The results show that the cap sensitivity of the self sensitive AN can be controlled in industrial processing, and that AN explosives having fine properties can be made from self sensitive AN in place of ordinary ANs
