摘要: 采用静电纺丝技术制备了用于除尘领域的涤纶纳米纤维膜,利用扫描电子显微镜对纤维膜微观形貌进行表征,确定了最佳纺丝条件,并将该条件下制得的纳米纤维膜附着在除尘滤料表面,对其进行阻力特性、分级计数效率及动态过滤性能测试.结果表明,15kV纺丝电压、21cm接收距离、18%纺丝液质量分数为最佳纺丝条件,在该条件下制备的纳米纤维过滤材料阻力较低,清灰性能良好,对3μm以下的微细粒子过滤效率达到99.99%以上,效率提升明显,能有效控制微细颗粒物.

Abstract: The polyester nanofiber membrane used in the field of dust removal was prepared by electrospinning. The fiber membrane microstructures were characterized by scanning electron microscopy. The optimum spinning conditions were determined. The nanofiber membrane under the optimum spinning conditions was attached to the filter surface, and the resistance characteristics test, the classification efficiency test and dynamic filtration performance test were applied to the nanofiber membrane filter. The results indicated that 15kV spinning voltage, 21cm receiving distance and 18% spinning solution concentration are the optimum spinning conditions. The nanofiber filter prepared under the optimum spinning conditions has low resistance and good cleaning performance. The filtration efficiency of fine particles below 3μm is over 99.99%, the filtration efficiency is improved obviously, which can effectively control the fine particles.
