摘　　要：以静液压试验结果不同的给水用硬聚氯乙烯(PVC-U)管材为研究对象,分别对试样进行二氯甲烷浸渍试验和拉伸试验,并采用扫描电镜(SEM)观察样品形貌。结果表明,管材生产过程中通过对塑化度的控制能得到静液压性能较好的管材。Unplasticized polyvinyl chloride （PVC-U） pipes for water supply with different static hydraulic test results were studied. The methylene chloride immersion test and tensile test were applied to evaluate various prope^ies of the samples. The morphology of the samples was investigated by scanning electron microscope. The results show that pipe production process through the control of plasticity can get better hydrostatic performance of the pipe.
