Изобретение относится к области технологии изготовления мембран для микро-, ультра- и нанофильтрации и может быть использовано в медицине, биологии, химической и пищевой промышленности в процессе удаления или концентрирования дисперсных частиц, находящихся в жидкостях и газах. Фильтрующий элемент для микро- и ультрафильтрации содержит грубопористую подложку 1 и нанесенную на нее тонкопористую мембрану, выполненную в виде спеченного волокнистого каркаса 3 и неволокнистой матрицы 4. Каркас 3 мембраны может содержать поверхностную пленку 5. Способ изготовления фильтрующего элемента отличается тем, что в качестве компонентов мембраны используют неорганические волокна и неволокнистые составляющие, причем вначале наносят на поверхность подложки слой неорганических волокон, а затем пропитывают раствором, содержащим соединения, переходящие при термообработке в неволокнистую составляющую.

The invention relates to the field of manufacturing technology of membranes for micro, ultra and nanofiltration and can be used in medicine, biology, chemical and food industries in the process of removing or concentrating dispersed particles in liquids and gases. The filtering element for micro- and ultrafiltration contains a coarse-porous substrate 1 and a thin-porous membrane deposited on it, made in the form of a sintered fibrous carcass 3 and a non-fibrous matrix 4. The framework 3 of the membrane can contain a surface film 5. the membranes use inorganic fibers and non-fibrous constituents, and first a layer of inorganic fibers is applied to the substrate surface and then impregnated with a solution containing their compounds, passing during the heat treatment in the non-fibrous component.
