| 摘 要： | 提出了用硅烷偶联剂Si-K和高分子材料Polym-B对硝酸铵进行双层包覆的新思路;利用光电子能谱仪和扫描电子显微镜表征了包覆效果,结果表明Si-K和Polym-B能对硝酸铵粒子进行很好包覆,在其表面形成均匀而完整的包覆层.通过测量吸湿性和结块性的变化研究了改性效果,数据表明改性后的硝酸铵吸湿性降低了近50%,结块性显著降低.

| Abstract: | Ammonium nitrate was coated by a coupling agent Si-K and polymer material Polym -B, surfaces of the coated AN particles were characterized by SEM and XPS. The hygroscopicity and caking tendency of the coated AN were measured. The experimen tal results showed that hygroscopicity and caking tendency of AN particles could be effectively reduced through coating. |
