引 言聚丙烯材质填料作为塔填料的重要一类 ,在化工上应用较为广泛 .与其他材质的填料相比 ,聚丙烯填料具有质轻、价廉、耐蚀、不易破碎及加工方便等优点 ,但其明显的缺点是表面润湿性能差 .研究表明 ,聚丙烯填料的有效润湿面积仅为同类规格陶瓷填料的 4 0 % [1] .由于聚丙烯
Introduction Polypropylene packing material is widely used in chemical industry as one of the most important packing materials in tower packing.Compared with other packing materials, polypropylene packing material has the advantages of light weight, low cost, corrosion resistance, easy to be broken and easy to process, etc. However, The obvious disadvantage is that the surface wetting performance is poor.Research shows that the effective wetting area of polypropylene packing is only 40% of the same type of ceramic packing [1] .Polypropylene
