摘要
通过正交实验,对溶剂蒸发法制备球形团聚硼颗粒的工艺参数进行优化,研究了固化温度和固化时间对球形团聚硼颗粒的形态、平均粒径大小及其分布的影响,用扫描电子显微镜观察了球形团聚硼粉的外观形态。结果表明,团聚硼粒子的形态圆整,粒径可控且分布均匀。最佳制备工艺条件为:搅伴速度70 r/m in,工艺温度20℃,硼粉与黏合剂的质量比为9∶1,固化温度70℃,固化时间7 d。
The parameters for perparation of spherical agglomerated boron particles with solvent evaporation process were optimized by orthogonal experiment. The effect of curing temperature and curing time on the appearance and distribution of particle size of spherical agglomerated boron particles were studied. The spherical agglomerated boron was characterized by SEM. The results show that the spherical agglomerated boron particles prepared by the optimum preparing method were smooth, regular in morphology. The optimum conditions are： stirring rate, 70r/min; solidified time, 7days; temperature, 20℃; mass ratio of B and binder, 9 ： 1; curing temperature, 70℃.
