Abstract

The work studies methods to improve the wettability of polymer packing elements involving the application of various geometric structures onto their surface. The authors of this work review the latest scientific studies that consider the phenomena of wetting on structured surfaces. A laboratory bench is developed for the study the profile and character of the flow of a liquid film over polymer plates with different surface structures. It is noted based on the results of the performed studies that the wettability of the surface strongly depends on its structure. A qualitative and quantitative comparison of the degree of wettability of the studied plates is presented, during which it is found that a network configuration of the surface of the plate is the most efficient. Recommendations on the practical application of the results of this work are indicated based on the obtained data.

表面结构对传热传质设备中聚合物填料润湿性的影响

摘要

这项工作研究了提高聚合物填料元件润湿性的方法，包括在其表面应用各种几何结构。这项工作的作者回顾了考虑结构化表面润湿现象的最新科学研究。开发了一个实验台，用于研究液膜在具有不同表面结构的聚合物板上的流动曲线和特性。根据所进行的研究结果注意到，表面的润湿性在很大程度上取决于其结构。对所研究的板的润湿程度进行了定性和定量比较，在此期间发现板表面的网络配置是最有效的。
