Title:
FLEXIBLE POROUS METAL FOIL AND MANUFACTURING METHOD FOR FLEXIBLE POROUS METAL FOIL
Document Type and Number:
WIPO Patent Application WO/2016/155621
Kind Code:
A1
Abstract:
A flexible porous metal foil, which is a sheet made of metal porous materials which use solid solution alloy, a metal simple substance of a face-centered cubic structure or a metal simple substance of a body-centered cubic structure as matrix phases, wherein the thickness of the sheet is greater than 200 μm and less than or equal to 1500 μm, the average aperture is 0.05 μm to 100 μm, and the porosity is 15% to 70%. The manufacturing method for the flexible porous metal foil comprises: (1) making raw material powder forming metal porous materials into a thick turbid liquid by means of a dispersing agent and a binding agent; (2) filling the turbid liquid into a forming die cavity of a film manufacturing fixture, and drying to form a homogeneous film; (3) pressing the film to improve the powder particle accumulation density in the film; and (4) sintering the pressed film to obtain the flexible porous metal foil. Also disclosed is a filtering bag for filtering use. The flexible porous metal foil has more uniform aperture distribution, and better flatness of the foil.
