| 摘要 |
Provided by the present invention is a process for making a wet-layed, non-woven sheet comprising metal fibers, which process comprises: (a) (i) preparing an aqueous dispensing fluid comprising a non-carboxy containing water soluble polymer in solution; and (ii) dispersing metal fibres and metal powder into said aqueous dispensing fluid, wherein the non-carboxy containing water soluble polymer is dissolved in the aqueous dispensing fluid in an amount such that the viscosity of the dispensing fluid with dispersed metal fiber and metal powder is suitable for wet laying techniques, and wherein the water soluble polymer comprises from 1 to 5 weight percent of the aqueous dispensing fluid; (b) applying the aqueous dispensing fluid with dispersed metal fiber and metal powder onto a screen, and (c) removing the aqueous dispensing fluid to thereby form a metal fiber/metal powder sheet. <IMAGE> |
