| 成果简介 | NOVELTY - Invention relates to production of hollow-fibre membranes for separation of gas or liquid mixtures. Disclosed is a wet method of forming a hollow-fibre membrane by successive immersion of the carrier into a container with a moulding polymer solution and into a container with a precipitation agent. Carrier is immersed in the container with the moulding solution through a through hole in the central part of the nozzle, which is installed on the container with the moulding polymer solution. When lifting the carrier from the container, the through hole forms the outer surface of the film from the moulding solution and controls the size of its outer diameter to obtain a hollow fibre membrane with a diameter of a given size after deposition. USE - Performing operations. ADVANTAGE - Invention enables to obtain hollow fibre membranes of uniform thickness along the entire length of the membrane, including from high-viscosity moulding polymer solutions, increases speed of making membranes while reducing consumption of moulding solution. 7 cl, 2 dwg, 13 tbl, 39 ex |
