| 摘 要： | 采用干-湿法纺丝工艺制备PVDF/PVC共混中空纤维膜,通过对水通量、孔径、截留率等的测试,研究了挤出速率、芯液流量、干纺程对PVDF/PVC中空纤维膜性能及结构的影响,并进行了详细的理论分析。试验结果表明挤出速率与膜通量存在最大值,芯液流量与膜通量及截留率呈线性关系,干纺程的影响效果跟挤出速率类似。可以通过改变纺丝条件来制备性能不同的中空纤维膜。

| Abstract: | PVDF/PVC hollow fiber membrane was prepared by dry-wet filature process, the influence of extruding velocity, bore fluid flow rate and air gap length on PVDF/PVC hollow fiber membrane was studied through testing permeation, aperture, retention rate. The results showed that there was a maximum value between extruding velocity and permeation, and the relation of bore fluid flow rate and permeation and retention rate was linear which was similar to air gap length. So different hollow fiber membranes could be obtained through changing spinning conditions. |
