摘要
测试和分析了常温条件下长期贮存丁羟胶的相对分子质量 ( Mr)、羟值 ( OH)和粘度 ( ηa)数据 ,研究了贮存丁羟胶对推进剂性能的影响。结果表明 :贮存丁羟胶的 Mr、OH和 ηa 变化不显著 。
Relative molecular weight ( M r),hydroxy value (OH) and viscosity (η a) of the long term stored HTPB at normal temperature were measured and analyzed.The effect of the stored HTPB on the properties of the propellant was investigated.The results indicate that M r,OH and η a of the stored HTPB has not obvious changes and the properties of the propellant prepared with the stored HTPB keep at original level.
