Encapsulation method of column type membrane end

The invention belongs to the field of preparation of hollow fiber membranes, and particularly relates to a packaging method of a column type membrane end socket, which comprises the following steps: injecting a liquid end socket material into a casting model along the liquid end socket material, injecting a packaging resin material into the casting model along a packaging material feed port, and enabling the injected upper interface to be lower than the water production end of the end socket; the density of the packaging resin material is smaller than that of the liquid end socket material, and the two materials are mutually insoluble; the curing temperature of the liquid sealing head material is higher than that of the packaging resin material. According to the technical scheme, the inner holes of the hollow fiber membrane filaments do not need to be blocked manually, the product reject ratio caused by human factors is avoided, and meanwhile it can be ensured that no hole blocking phenomenon exists 100%. 本发明
