Claims (4)

1. Фильтрующий материал, состоящий из волокнистого и мелкодисперсного материала, отличающийся тем, что волокнистый материал выполнен в виде пористой матрицы из волокон, скрепленных между собой в местах пересечения, при этом размеры пор уменьшаются по толщине матрицы, а мелкодисперсный материал состоит из частиц разных размеров, которые распределены в объеме пор матрицы с уменьшением размеров частиц по толщине матрицы.1. The filter material, consisting of fibrous and finely dispersed material, characterized in that the fibrous material is made in the form of a porous matrix of fibers bonded together at the intersection, while the pore sizes are reduced along the thickness of the matrix, and the finely dispersed material consists of particles of different sizes that are distributed in the pore volume of the matrix with a decrease in particle size over the thickness of the matrix. 2. Материал по п. 1, отличающийся тем, что пористая матрица выполнена из волокон, диаметр которых уменьшается, а плотность упаковки увеличивается по толщине слоя. 2. The material according to p. 1, characterized in that the porous matrix is made of fibers, the diameter of which decreases, and the packing density increases along the thickness of the layer. 3. Материал по пп. 1 и 2, отличающийся тем, что пористая матрица выполнена из фильтропласта. 3. The material according to paragraphs. 1 and 2, characterized in that the porous matrix is made of filter plastic. 4. Способ изготовления фильтрующего материала, включающий приготовление суспензии мелкодисперсного материала и ее осаждение на волокнистый материал путем фильтрования, отличающийся тем, что суспензию мелкодисперсного материала готовят с концентрацией 0,1-2 мас. %, а фильтрование суспензии через волокнистый материал проводят в одну стадию со скоростью не менее 1 мм/с. 4. A method of manufacturing a filter material, comprising preparing a suspension of fine material and its deposition on the fibrous material by filtering, characterized in that the suspension of fine material is prepared with a concentration of 0.1-2 wt. %, and filtering the suspension through the fibrous material is carried out in one stage with a speed of at least 1 mm / s.
