摘要
以聚丙烯腈(PAN)为原料,在不同工艺参数条件下,通过静电纺丝技术制备PAN纳米纤维并分别沉积在熔喷、针刺和热轧非织造材料表面,制备成静电纺复合空气过滤材料,并对复合材料的结构、纤维直径、孔径和过滤性能进行表征。结果表明,当接收材料为熔喷非织造材料、PAN质量分数为14%、接收时间为15min时,复合材料过滤效率达到99.67%,过滤阻力为57Pa,平均孔径为3.63μm,品质因数为10.02×10-2 Pa-1,此时综合过滤性能最佳。
The polyacrylonitrile(PAN)nanofibers were prepared by electrospinning,and the nanofibers were received respectively by melt-blown,needle-punched and hot rolled nonwoven materials to prepare electrospinning composite air filter materials.Then the structure,fiber diameter,average pore size and filtration performance of composite materials were investigated.The results indicate that when the receiving material is melt-blown nonwoven material,the mass fraction of PAN spinning solution is 14%and the receiving time is 15 min,the filtration efficiency of composite material can reach99.67%,and the filtration resistance is 57 Pa,the average pore size is 3.63μm,and the quality factor is 10.02×10-2 Pa-1.At this point,the comprehensive filtration performance of the composite material is the best.
