摘要

采用水溶性聚乙烯醇纳米纤维作为胶粘层,利用蒸汽雾化方法代替高温处理,通过圆辊拉伸加压的方式制备了PET/PPS纳米纤维膜复合滤料,并对复合滤料的性能进行了表征.结果表明,压力为0.436N/cm²,PVA纺丝量为42.857mL/m²,加压过程中的温度为20℃时制备的PET/PPS纳米纤维膜复合滤料覆膜牢度最高,达到4.521N.PET/PPS纳米纤维膜复合滤料对粒径为0.3μm微细颗粒物的过滤效率达到98.86%.在动态过滤性能中,复合滤料在进行30个定压喷吹周期后,单个周期完成时间为13.5min,残余阻力为265.4Pa,优于现有PTFE覆膜滤料.

Abstract

Water-soluble polyvinyl alcohol nanofibers were utilized as the adhesive layer, and a steam atomization method was employed as a substitute for high-temperature treatment to fabricate PET/PPS nanofiber membrane composite filters through a circular roller stretching and pressing technique. The performance of the composite filters was characterized. The results indicated that the adhesion strength of the PET/PPS nanofiber membrane composite filter reached a maximum of 4.521N when the pressure was set at 0.436N/cm², the PVA spinning amount was 42.857mL/m², and the processing temperature during the pressurization was maintained at 20℃. The filtration efficiency for fine particulate matter with a diameter of 0.3μm achieved 98.86%. In dynamic filtration performance tests, after 30 cycles of constant pressure blowing, the time required for a single cycle was recorded as 13.5minutes, with a residual resistance of 265.4Pa, which outperformed existing PTFE-coated filter materials.
