Claims (1)

Способ получения мембранных трубчатых фильтрующих элементов формированием на открытопористой подложке жидкой пленки из гомогенного раствора фторполимера, растворителя и нерастворителя и отверждением фторполимера с образованием селективно проницаемой мембраны, отличающийся тем, что на поверхность открытопористой трубки наносят раствор фторполимера, в котором в качестве нерасворителя используют 25-33 мас. % изопропилового спирта, или его смеси по массе 1,0: 0,4-1,5 с уксусной кислотой, или 1: 0,016-0,180 с поливинилпирролидоном, или 1: 0,5-1,5: 0,015-0,035 с уксусной кислотой и поливинилпирролидоном одновременно при следующем соотношении компонентов раствора (мас. %) : фторполимер 8-25, нерастворитель 20-40, растворитель - остальное.A method of producing membrane tubular filtering elements by forming a liquid film on an open-porous substrate from a homogeneous solution of a fluoropolymer, a solvent and a non-solvent, and curing the fluoropolymer to form a selectively permeable membrane, characterized in that a fluoropolymer solution is applied to the surface of the open-porous tube, in which 25-33 is used as a non-solvent wt. % isopropyl alcohol, or a mixture thereof by weight of 1.0: 0.4-1.5 with acetic acid, or 1: 0.016-0.180 with polyvinylpyrrolidone, or 1: 0.5-1.5: 0.015-0.035 with acetic acid and polyvinylpyrrolidone at the same time in the following ratio of solution components (wt.%): fluoropolymer 8-25, non-solvent 20-40, solvent - the rest.
