Abstract
An apparatus for potting membranes. The apparatus may include a mould for receiving ends of the membranes, means for forming a first layer of a curable resin material around the ends in the mould, and means for applying a second layer of a flexible resin material to the first layer prior to full curing of the first layer. The flexible resin material may be chemically reactive with the curable resin material to form an adhesive bond therebetween. A potting sleeve may be positioned within the mould. A centrifuge may receive the curable resin and/or the flexible resin material upstream of the mould.
Claims12
An apparatus for potting an array of hollow fibre membranes, each fibre membrane comprising an end, the apparatus comprising:
- a mould for receiving the ends of the hollow fibre membranes, the mould including a cavity having an upper portion with a first diameter and a base portion with a second diameter, the second diameter being greater than the first diameter, the base portion configured to hold a prepot supporting the ends of the membrane fibers during a potting process;
- a source of an epoxy resin material fluidly connected to the base portion of the cavity;
- a source of a polyurethane resin material fluidly connected to the upper portion of the cavity;
- and
- means for forming a layer of the epoxy resin material around the membrane ends in the mould.
