| 目的 为了评价测试装置和方法条件对薄膜耐穿刺性的影响，对测试装置的材质、尺寸精确性及测试条件等因素进行针对性分析。方法 利用显微镜对比国内外不同批次及材质穿刺针的尺寸和尖端结构，并依次对均匀稳定的薄膜进行穿刺力测试。结果 相比直径和半径偏差均低于±0.05 mm的穿刺针，1#，4#，5#，6#，7#穿刺针的穿刺力存在明显波动；尖端半球具有较差圆弧度的穿刺针试验结果标准偏差较大，重复性较差；相比于合金钢材质的穿刺针，高速钢制造的穿刺针穿刺力平行性较好，针头无弯曲变形、无穿刺力递增等现象；使用上下环直径不一致的固定环测试所得穿刺力结果的平行性较差。结论 采用具有较好圆弧度、不易变形且针头尺寸精准的穿刺针，并配合使用上下环直径一致且合理的固定环进行测试，可准确反映薄膜的耐穿刺性。 |
| 英文摘要: |
| The paper aims to research the influences of testing device and method conditions on the puncture resistance of film and analyze factors such as material and dimensional accuracy of the testing device and conditions of test. The size and tip structure of puncture needles of different batches and materials at home and abroad were compared by microscope, and the puncture force of uniform and stable films were tested in turn. Compared with puncture needles which diameter and radius deviations were less than ±0.05 mm, the puncture force of puncture needles 1#, 4#, 5#, 6#, 7# fluctuated obviously. The needle tips with poor arc had large standard deviation and poor repeatability. Compared with the puncture needles of alloy steel, the puncture force of puncture needles with high-speed steel had better parallelism, force value was not increasing and the needle did not bend. The parallelism of puncture force which using upper and lower fixed rings with different diameters was poor. By using a puncture needle with good arc, non-deformable and accurate needle size, and together with consistent upper and lower ring diameters and reasonable fixed ring for testing, the film puncture resistance can be reflected accurately. |
