FILTERS MADE FROM TUBULAR RIGID POROUS PLASTICS

摘要

A rigid tubular filter for filtering particulate from a flowing fluid. The filter includes a plurality of polymer particles located within the confines of a tube shape having a hollow interior and an exterior. The filter includes a plurality of adhesion points among the plurality of polymer particles. The plurality of adhesion points include melt fusion points and the plurality of adhesion points fix the polymer particles relative to each other to provide the tube shape as a rigid structure. The filter includes a plurality of pores extending between the particles so as to allow fluid flow between the exterior and the hollow interior of the tube shape. The fixed polymer particles blocking particles within the fluid during the flow of the fluid between the exterior and the hollow interior of the tuber shape. An associated method provides the filter.
