Abstract

SummaryVarious types of micro-filters were made of anodic oxide films of aluminium by dissolving Al substrate and barrier layer partially in the form of a circle. The diameter of the micro-pores in the fillers were controlled by bath voltage during anodizing and by pore-widening technique. The flow rate of distilled water through the films was measured under various conditions and revealed that the measured values of flow rate of water relatively agreed with the values calculated by the equation of Hagen-Poiseuille. It was also demonstrated by experiments of breakdown of the filter by air-pressure that the strength of the filter was nearly proportional to the thickness of the filter and was inversely proportional to diameter of filter, as suggested by the equation from material strength theory.

铝阳极氧化膜微过滤器的特性研究

摘要利用铝阳极氧化膜，将铝衬底和阻挡层部分溶解成圆形，制成各种类型的微过滤器。通过阳极氧化时的电解电压和扩孔技术控制填料中微孔的直径。对不同条件下蒸馏水通过膜的流速进行了测量，结果表明，蒸馏水流速的实测值与hagens - poiseuille方程的计算值较为吻合。压滤机的破碎实验也证明了压滤机的强度与压滤机的厚度几乎成正比，与压滤机的直径成反比，这与材料强度理论的公式一致。

期刊介绍： Transactions of the Institute of Metal Finishing provides international peer-reviewed coverage of all aspects of surface finishing and surface engineering, from fundamental research to in-service applications. The coverage is principally concerned with the application of surface engineering and coating technologies to enhance the properties of engineering components and assemblies. These techniques include electroplating and electroless plating and their pre- and post-treatments, thus embracing all cleaning pickling and chemical conversion processes, and also complementary processes such as anodising. Increasingly, other processes are becoming important particularly regarding surface profile, texture, opacity, contact integrity, etc.
