Preparation and characterization of spheroidization of N2H5N5 crystals
摘要
Abstract
In order to improve the bulk density of N2 H5 N5 and its safety,the spheroidization of N2 H5 N5 crystals is studied.The effects of temperature,solution dropping speed,solvent-non-solvent volume ratio and stirring speed on the bulk density of N2 H5 N5 are investigated.At the same time,characterization experiments such as scanning electron microscope(SEM),particle size analysis,thermogravimetric analysis and sensitivity test are carried out on the final product.The research results show that the optimum process conditions are as follows:the solution temperature is 25℃;the dropping speed is 8 mL/min;the volume ratio of methanol to 1,4-dioxane is 1∶7;the stirring speed is 400 r/min;the additive is 0.1%β-cyclodextrin.Under these conditions,the highest bulk density is 1.221 7 g/cm3;the morphology is spheroid;the average particle size is 36.133 μm.The thermal decomposition temperature of spherical N2 H5 N5 is 103.64℃,and its impact sensitivity is 8 J and friction sensitivity is 54 N tested using the BAM standard method.关键词
