The producing process of Sintered porous polyethylene (PE) filters

The producing process of Sintered porous polyethylene (PE) filters


Material: Ultra high molecular weight polyethylene powder

Application: They are widely used in laboratory solid-liquid separation, medical and pharmaceutical equipment, automatic industry devices, and water filtration systems


Manufacturing method: it is manufactured by a special sintering process, in which the granules of plastic are heated until their surfaces soften, and fuse at the contact faces, while retaining more or less their original shape. The shaped body created thus has open continuous pores, whose size and number depends on the sintering conditions and the size of the polymer particles selected


Features: PE filter elements are environmentally compatible. They produce no toxic waste in themselves and can be washed off and reused. There is no contamination of material from filter fibers like fabric and cartridge media elements. Uniform pore size distribution, strong acid and alkali resistance, high temperature resistance, good mechanical properties, and strong resistance to organic solvents. The production of large-scale water treatment equipment can adopt automatic or manual recoil slag removal method, solid particles can be recovered by dry slag removal, without frequent replacement of filter elements, automatic operation and cleaning, low filtration cost and other advantages, which are well received by users.
