亚高效针刺熔喷复合过滤材料的制备及性能研究
|
摘要
采用在线复合的方式,将粗效针刺空气过滤布与熔喷布复合,制备了一种具有亚高效过滤性能的复合过滤材料。对复合前各组分及复合材料进行了定量、过滤效率、透气、拉伸强度、剥离强度等测试。结果表明,该复合材料兼具针刺和熔喷空气过滤材料的优点,具有强度大、抗胀破力大、过滤效率高、使用周期长以及梯度过滤的优异性能。亚高效针刺熔喷过滤材料在降低工业成本,提高过滤材料的过滤效率方面具有广阔的应用空间和发展前景。
A sub-high efficiency composite filter material was prepared by on-line compounding coarse efficient needle-punched air filter material and melt-blown filter material. The components before compounding,basic weight,filtration efficiency,air permeability,tensile strength and peeling strength of the composite filter materials were tested. The experimental results indicated that the composite filter materials had the advantages of both needle-punched and melt-blown air filtration materials such as high strength,high bursting resistance,high filtration efficiency,long service life and gradient filtration. It had broad application fields and prospects in reducing industrial costs and improving filtration efficiency of filtration materials.
