Method of forming a pot from hollow fibre membranes set in layers of resin

摘要

A method of forming a pot for an array of hollow fibre membranes 7 typically used in filtration systems is disclosed. The method includes the steps of placing the ends 6 of the fibre membranes 7 in a mould 5, forming a first layer of curable resin material in a non-cured state around the fibre membrane ends, applying a second layer of a polyurethane resin material to the first layer 20 prior to full curing of the first layer, at least partially curing both layers and removing the pot formed from the mould 5. The second polyurethane resin material layer is chemically reactive with the first layer resin material to form an adhesive bond, and the polyurethane resin material is of higher flexibility than the resin layer material when each layer is fully cured.
