在渗透性能测试方法归纳介绍的基础上,开展了试验及比较,初步确定了相应的测试试验规范。结合风机叶片的具体工艺和使用部位等,初步选定了缝编织物的渗透性能评估参数和测试方法,以对风机叶片用缝编织物渗透性能测试评估方法的统一规范确定提供一些思路。
Based on the introduction of permeability test methods, experiments and comparisons were carried out, and corresponding test specifications were preliminarily determined. According to the specific process and the use site of the fan blades, the parameters and test methods of permeability evaluation of the stitchbonded fabric were preliminarily selected to provide some ideas for the uniform specification and determination of the permeability test of the fan braid.
