A method for producing a composite filter tube and filter element made of a multilayer metal mesh and metal powders, including: knitting to obtain metal meshes of different mesh numbers, obtaining a layered structure by means of a lamination method, then putting the layered structure in a vacuum furnace for sintering processing, sintering a metal composite layer to obtain a composite filter sheet and tube made of a multilayer metal mesh and metal powders with a multilayer metal mesh as a structure support layer and a metal powder sinter structure as a fi...
1. A method for producing a composite filter tube and filter element made of multilayer metal mesh and metal powders, comprising: weaving wires to form a metal mesh of different mesh numbers, and then stacking up the metal mesh of different mesh numbers to obtain a layered structure on a principle that the mesh number increases from one side to the other, and number of layers of the layered structure is 1˜5;putting the layered structure in a vacuum furnace for 10˜30 hrs uninterruptedly sintering at 900˜1500° C. to obtain a multilayer metal mesh;after coo...
