不同热处理介质对聚氨酯系中空纤维膜性能的影响
Effect of different hot-treatment media on the properties of polyurethane based hollow fiber membrane
摘要
Abstract
Polyurethane(PU) based hollow fiber membranes were prepared by melt-spinning method, and the influences of different hot-treatment media on the properties of PU based hollow fiber membranes were studied. The results show that with the increasing in theoretical draw ratio, the pure water flux (PWF) increased by hot-water treatment, but increased and then decreased by hot-air treatment. The PU based hollow fiber membrane treated by hot-water can improve the breaking elongation rate, but can improve the fracture strength treated by hot-air. In the same testing pressure, the PU based hollow fiber membrane treated by hot-water is easier to achieve stability than that treated by hot-air.、关键词
