| 摘 要： | 采用DTA-TG研究了包覆材料AP、LiF对硼颗粒热氧化特性的影响。并通过氧弹式量热计测试了不同粒度团聚硼的燃烧热及含硼富燃料推进剂的爆热,研究了包覆材料AP、LiF以及团聚硼颗粒粒度与团聚硼燃烧热和推进剂爆热之间的关系。结果表明,AP有利于提高硼的氧化程度,LiF可显著降低硼的氧化温度。包覆材料可显著改善了硼颗粒的燃烧性能,利于团聚硼颗粒及推进剂能量的释放,且小粒度的团聚硼有利于硼的燃烧。

| Abstract: | The thermal behavior of different boron powder coated with AP and LiF was investigated by means of DTA-TG. The effects of coating and agglomeration on combustion heat of agglomerated boron and explosive heat of boron based fuel-rich propellant were studied. The results show that boron coated with AP promotes the oxidation degree of boron in oxygen environment while boron coated with LiF reduces the temperature of boron oxidation. The coated boron has improved combustion and released more heat. Small particle size of agglomerated boron is beneficial to boron combustion. |
