摘要
研究了纺丝液浓度对聚丙烯腈(PAN)静电纺丝纤维直径,以及对PAN静电纺丝纳米纤维膜复合滤材过滤性能的影响。测试结果表明,纺丝液浓度增加,静电纺丝纤维直径变粗,孔径增大,其中质量分数为16%的纺丝液具有良好的纺丝性能,静电纺丝所得的纳米纤维直径均匀,复合后滤材在颗粒直径0.3μm,过滤风速5.3 cm/s的测试条件下,过滤效率达到99.98%,阻力为138 Pa,达到H13级别,具有高效低阻特性。
The effect of spinning solution concentration on the diameter of PAN electrospun nanofiber and the filtration performance of the composite filter material was studied.The results show that as the solution concentration increases,the diameter of fibers and the pore diameters increase.The test results show that the solution of 16%PAN has good spinning performance,and the diameter of the nanofiber obtained by electrospinning is uniform,and the filtration efficiency of the composite filter material is 99.98%with 138 Pa under 0.3μm particle diameter,5.3 cm/s filtration wind speed,and it reaches H13 leve,and it has the characteristics of high efficiency and low resistance.
