A method for preparing a uniform metal porous film on a large aperture screen surface

Abstract

The application discloses a method for preparing a uniform metal porous film on a large-aperture wire mesh surface, which comprises the following steps: rolling a first metal wire mesh with an organic film to obtain a second metal wire mesh, spraying through the second metal wire mesh to obtain a third metal wire mesh, granulating to obtain second spherical granular materials, granulating to obtain third spherical granular materials, rolling the third metal wire mesh with the third spherical granular materials to obtain a wire mesh film green body, and sintering and cooling the wire mesh film green body to obtain a wire mesh with a metal porous film compounded on the surface. The application mainly solves the problems of thickening and defects during rolling of the wire mesh and the powder, and the method for preparing the uniform metal porous film has the advantages of simple process, high product yield and stable performance, and can meet the demand of new energy, fine chemical industry, coal chemical industry and other industries for high-quality filtering materials.
