Abstract

The invention discloses a green body, a sintered porous metal film and a dust removal method, and solves the technical problem that the sintered porous metal film with high strength and high gas flux is difficult to obtain in the prior art. The green body of the sintered porous metal film comprises a precursor layer, the precursor layer is provided with a first porous metal supporting layer and a coating attached to the surface of the first porous metal supporting layer, and the coating is provided with a metal powder raw material used for powder metallurgy; the reinforcing layer is provided with a second porous metal supporting layer, the strength and / or air flux of the second porous metal supporting layer are / is larger than those of the first porous metal supporting layer, and the reinforcing layer and the precursor layer are arranged in an overlapped mode.

Description

technical field [0001] The present invention relates to the technical field of flexible metal filter materials, in particular, to a green body, a sintered porous metal film and a dust removal method. Background technique [0002] Sintered porous metal films are widely used in gas filtration due to their excellent high temperature resistance, corrosion resistance, flexibility and filtration accuracy, especially for high temperature dusty gas filtration. In order to improve the quality of the sintered porous metal film, the Chinese invention patents with publication numbers CN104874798A, CN104959611A, CN104959612A and CN104874801A disclosed by the applicant of the present application disclose the preparation method of the sintered porous metal film, which mainly includes the steps of: first obtaining a slurry, The slurry contains metal powder raw materials selected according to the required alloy system, and then the slurry is attached to the porous support body, dried to obta...
