PROCESS FOR FORMING POLYACRYLAMIDE MEMBRANES

摘要

A process for producing a plurality of polyacrylamide membranes comprising (a) providing acrylamide monomer solution and crosslinking agent to a membrane casting vessel; (b) providing a casting plate to the bottom of the vessel; (c) providing a membrane substrate on the casting plate; (d) providing a casting plate on the membrane substrate; (e) repeating steps (c) to (d) to form a plurality of layers of casting plates and membrane substrates; (f) providing a weighting material to the plurality of layers; and (g) allowing the acrylamide monomer to polymerize to the membrane substrates to form polyacrylamide membranes; wherein at least one casting plate is a heat-resistant plastic film.
