超细球形高氯酸铵的制备与性能表征
Preparation and property characterization of superfine spherical ammonium perchlorate
摘要
Abstract
Ammonium Perchlorate(AP) was smashed by jet mill,and then superfine spherical AP particles was prepared by planetary ball mill. Their morphologies,particle and IR spectra were characterized with scan electron microscope( SEM) ,Micron la-ser particle size analyzer and Fourier transform infrared spectrometer. Bulk density and thermal mechanical properties of superfine spherical AP and non spherical AP with the same size were characterized by standard container and differential scanning calorimeter (DSC).The impact sensitivity and friction sensitivity,hygroscopicity and caking of superfine spherical AP and non spherical AP with the same size were studied. The results show that superfine spherical AP prepared by the milling method has a high rate of sphe-roidization,good sphericity,smooth surface,fewer defects and thermal decomposition peak moves to low temperature. In addition, the impact sensitivity and friction sensitivity of superfine spherical AP are lower than the non-spherical AP,and hygroscopicity and ca-king are effectively improved.关键词
