PVC复合面料性能对PC3S制件质量影响

Effect of PVC Compound Fabric Properties on the Quality of PC3S Manufactured Parts

摘要: 本文对PC3S工艺生产的门板中部插件PVC复合面料物理性能进行研究，结果表明静态伸长率及经纬向静态伸长率差值是影响制件表面缺陷的主要因素，PVC复合面料经向静态伸长率为4.4%~9.0%，纬向静态伸长率为9.3%~12.9%。差值在2.6%~7.5%之间时制件的表面质量良好。厚度、面密度、撕裂力、PVC表皮与泡沫、泡沫与衬布之间的结合力检测结果对制件表面质量影响不大，永久伸长率因其测量值较小，不作为衡量表面质量的重要指标之一。

Abstract: The physical properties of door panel insert PVC compound fabric manufactured in PC3S process were studied. The results show that static elongation and the difference between wrap and weft static elongation are the main factors influencing the surface quality. The parts are in good quality when the wrap static elongation is 4.4% - 9.0%; weft static elongation is 9.3% - 12.9%; the differ-ence between wrap and weft static elongation is 2.6% - 7.5%. The test results of thickness, density, tear force and the adhesion between skin and foam, foam and cloth had less impact on product surface quality. Permanent elongation wasn’t the important indicators for measuring the surface quality due to its small measured value.
