过滤阻力和过滤效率是玻纤空气滤材的关键参数。实际应用中,为了优化滤材阻力和效率之间的矛盾,通常会选择多种尺寸的纤维搭配使用。对这种滤材的过滤阻力进行预测,对于高性能滤材的研制具有重要意义,而目前对玻纤滤材过滤阻力的理论计算大部分还局限于单种纤维的理想情况。本文将针对由多种玻纤原料制备的滤材,根据不同玻纤的比表面积,利用Kozeny—Carman方程计算由此制备的滤材过滤阻力。这种方法计算的过滤阻力理论值与实际测量值非常接近,相关系数R2=O.9969,可为过滤材料的优化设计提供一定的依据。

Filtration resistance and efficiency are the key properties of glass fiber air filter media. In practice, various fibers are combined to optimize the contradiction of filtration resistance and efficiency. For studying high performance filter media, it's of great importance to predict the filtration resistance. The theoretical calculations are mainly confined to the ideal filter media constituted by only one kind of fiber. This paper aims at multi-component glass fiber filter media, and filtration resistance is calculated theoretically using specific surface area of different glass fibers by Kozeny-Carman Equation. The theoretical filtration resistance is very close to the experimental results with correlation coefficient R2 --0.9969. It will definitely benefit the optimal design of f'dter media.
