对超细及市售CaCO3在低含量(≤1%)的情况下对丁羟推进剂燃烧性能的影响进行了研究,结果发现CaCO3低含量时可提高推进剂的燃速且超细CaCO3比市售CaCO3的催化效率高。进一步研究了超细CaCO3与金属氧化物M2O3组合对推进剂燃烧的催化作用,结果表明两者有协同效应,其组合的燃烧催化效果较各自单独使用的催化效果要好。
The effect of ultrafine and commercially available CaCO3 on the combustion performance of the propellants was studied under the condition of low content (≤1%). The results showed that when the content of CaCO3 is low, the burning speed of the propellants can be increased and the ultrafine CaCO3 ratio Sales of CaCO3 high catalytic efficiency. The catalytic effect of ultrafine CaCO3 and metal oxide M2O3 on the combustion of propellants was further studied. The results show that both of them have a synergistic effect, and the catalytic effect of the combination of them is better than that of the catalyst alone.
