摘要:
为消除高聚物黏结炸药（PBX）中的低密度缺陷，采用正交试验法和单因素分析法设计了工艺试验，研究了捏合时间、捏合温度、转速、药浆静置时间4个混合工艺参数对热塑性高聚物黏结炸药均匀性的影响。结果表明：黏结剂分布不均匀，在CT检测中表现为低密度点，在剖面试验中表现为黏结剂胶团，胶团与炸药之间逐渐过渡，没有明显的界面；药浆静置时间是影响黏结剂分布的主要因素，其次是捏合机转速；当温度80~90 ℃、捏合时间60~180 min时，捏合温度和捏合时间是次要因素；确定最佳工艺参数为：捏合温度85 ℃，捏合时间120 min，转速30 r/min，静置时间60~120 min，试验验证了参数的有效性。
Abstract:
In order to eliminate the defect of low density in the polymer bonded explosives (PBX), the influence of four parameters including kneading time, kneading temperature, rotation speed and standing time of slurry on mixing uniformity of a thermoplastic PBX were investigated by orthogonal experiment and single factor analysis method in technological test. Results show that the binder uneven distribution exhibits as low density dot in CT detection and micellar in section test respectively, and there is no obvious interface between explosive and micellar due to their mutual gradual transition. Standing time of slurry is the major factor affecting binder dispersibility, followed by kneader rotation speed. The kneading temperature and kneading time are subordinate factors within interzone of 80~90 ℃ and 60~180 min respectively. Finally, the optimal process parameters determined and validated by tests are kneading temperature 85 ℃, kneading time 120 min, rotation speed 30 r/min and standing time of slurry 60~120 min.
