Title:
微細構造をもつ順序カラム・パッキン
Document Type and Number:
Japanese Patent JP4601198
Kind Code:
B2
Abstract:
An ordered column packing-in the form of packing layers containing flow channels (2)-has a foil-like material (1) with a fine structuring (10). The foil-like material is profiled with concave structure elements (3b; minus sign -) and convex structure elements (3a; plus sign +) in an alternating arrangement. An average distance "a" exists between centers of adjacent concave and convex structure elements respectively. This average distance "a" is substantially smaller than a distance between centerlines (20) of adjacent flow passages. The foil-like material has a second fine structuring in the form of regularly arranged apertures (5). An average distance "b" between centers of adjacent apertures is smaller than the average distance "a", preferably smaller by at least 50%; and edges (51, 52) of the apertures have in each case a shape including convex and concave locations (6a, 6b).
