Изобретение относитс к cnocoD atT Заготовки пенополиуретана с диа- получени пористой керамики и кера- метром чеек 1-2 мм пропитывают ке- мических пенофильтров.SUBSTANCE: invention relates to cnocoD atT. Preparations of polyurethane foam with diaphragm of porous ceramics and with a ceramometer of cells of 1-2 mm are impregnated with ceramic foam filters.
Цель изобретени - увеличение механической прочности и проницаемости. The purpose of the invention is to increase the mechanical strength and permeability.

После пропитки избыток шликера отжимают валками и полуфабрикат сушат при в течение 3 ч. Затем на вйсушенные заготовки по предлагаемому способу, например валками или погружением, нанос т на глубину 3-7 мм слой шликера. Поверхности фильтров с нанесенным шликером продувают сжатым воздухом при давлении 0, Mia. При этом упрочн ющийAfter impregnation, the excess of the slip is squeezed out by rollers and the semi-finished product is dried for 3 hours. Then, a layer of the slip is applied to the dried workpieces of the proposed method, for example rolls or immersion, to a depth of 3-7 mm. The surfaces of the filters with applied slurry are blown with compressed air at a pressure of 0, Mia. At the same time strengthening
