FIELD: chemical industry; oil refining industry and other industries. ^ SUBSTANCE: the invention is pertaining to production of materials for the filtering water-separating elements used in devices for purification of organic fluids, predominantly, hydrocarbon fuels, oils, oil products from the emulsified water and mechanical impurities, and may be used for purification of aircraft and car fuels in chemical industry, oil refining industry and other industries. The porous reinforced material is produced out of a permeable in all directions polymeric material with a side-porous deep structure having a total porosity of no less than 50 % with the sizes of the elementary pores, predominantly, of 10 - 200 microns. At that the porous reinforced material is formed out of a framed material having filaments or fibers with a diameter, predominantly, of 5 - 400 microns, and an arranged between the above mentioned filaments or fibers filler manufactured out of a porous polyvinyl formal produced by the method of a dew-point structurization with the thermal treatment of a homogenized in water composition containing at least polyvinyl alcohol and aldehyde. The element for the screen-water-separator contains a filtering-coagulating septum embraced by a perforated shell rings and limiting from above and from below covers. At that the septum is made multilayered out of a sheet manufactured out of the above porous reinforced material. The technical result consists in an increased effectiveness of purification of fuels (jet engine fuels and diesel fuels) and the gaseous oil products from water, and also asphalt-resinous and sulfur-containing materials, an increased service life and productivity of the filtering screens based on the indicated filtering-coagulating material. ^ EFFECT: the invention ensures an increased effectiveness of purification of jet engine fuels, diesel fuels, gaseous oil products from water and also asphalt-resinous and sulfur-containing materials, service life and productivity of the filtering screens based on the filtering-coagulating material. ^ 13 cl, 3 dwg |
