Title: Filter containing flake-shaped powder coating layer and manufacturing method therefor
Inventor: YUN JUNG YEUL
IPC: B01D39/20
Filed: 2019-06-19
Abstract: The purpose of the present invention is to provide a filter superior in terms of both filtration rate and permeability and a manufacturing method therefor. To this end, the present invention provides a filter comprising: a porous metal support having a first pore size; and a metal coating layer formed on the support and having a second pore size smaller than the first pore size, wherein the coating layer is formed to have a three-dimensional pore structure as flake-shaped metal powders are bonded to each other. In addition, the present invention provides a method for manufacturing the filter. According to the present invention, the formation of the coating layer from the flake-shaped second powder increases the porosity with the consequent improvement of permeability and makes the fluid paths more complex to increase the filtration rate. In addition, the present invention has the advantage of reducing the required amount of the coating layer material as the coating layer thickness required for the same permeability and filtration rate is smaller compared to the use of spherical powder. Furthermore, there is no need for introducing an additional layer for filtering out microparticles because the flake-shaped powder constituting the coating layer makes the fluid path complicated.
