摘要
通过拉伸试验,测定了某聚丙烯粮食柔性集装袋基材的基本力学性能,分析了其力学性能预期值与试验值存在差异性的原因,从而得出在粮食柔性集装袋设计与生产中:应对扁丝强度进行控制,确保整经过程中扁丝所受张力均匀,提高基布的强力利用率;袋体纵横向基布应选用强度相同的扁丝材料;对于连接部,应优化缝制方法,控制集装袋在受到极限载荷时能使连接部与袋体基布保持断裂一致性,避免材料浪费。
The basic mechanical properties of polypropylene FIBC base material were tested by tension experiment,the reason of differences in mechanical properties of main base material between expectant value and experimental valuewas analyzed. And the advertent issues were obtained during FIBC production and designing as follow： by controlling thestrength of ribbon-like filament to ensure that the tension received during beam-warping is well-distributed in order toimprove the strength efficiency; the fabric materials with same strength should be selected for longitude and woof fabric ofbag body; optimizing the sewing method for connection parts to make them breaking at the same time with fabric of bagbody in order to avoid material wasting.
