    摘要:

    采用HAAKE粘度计测定硼粉/丁羟简单体系和实验推进剂药浆屈服值和表观粘度,研究了硼粉的处理效果和处理硼粉BS对硼含量为35%~40%实验配方药浆工艺性能的影响。结果表明:在研究处理硼粉BD、BW、BT和BS系列中,BS的处理效果最好,处理工艺稳定。用处理硼粉BS制成的实验药浆具有较好的可浇性、流平性和适用期。实验药浆的流体特征,在出料初期2~3 h内呈Casson或Bingham流体,有显著剪切稀化和明显的静止结构恢复特征。

    Abstract:

    In the HTPB/Boron simple system and the HTPB propellant composed of total solid loading 70~75wt% containing modified boron powder BS 40~35wt%,the effects of modified boron and the processing characteristics of propellant filled boron powder BS were studied by means of yield value and apparent viscosity measured with HAAKE RV20 M5/SV2LF and M5/SV2 systems. The results show that according to the processing stability,BS is the best one of all the modified products including BD、BW、BT and BS. The propellants filled BS exhibit a good castability,flow level and long potlife,and after mixing 2~3 h the slurry can be described with Casson or Bingham model,when shear up and down to stationary it exhibited obvious shear-thining and constraction recovery respectively.
