| 摘 要： | 塑料塔填料表面能低，润湿性差，不利于传质。增大表面粗糙度以提高表面能与改变表面分子结构而增加表面极性是改善塑料塔填料分离性能的两个主要途径。本文着重介绍了表面糙化、表面极化、表面接枝及等离子体表面处理等表面改性技术。

| Abstract: | Coasening surface for raising surface tension and changing surface molecule structure for increasing surface polarity are main methodes to improve the surface wetting property of plastic tower packing. This paper introduces some surface modification techniques such as surface coarsening, surface polarizing, surface grafting, plasma surface treat-ment and so on. |
