    摘要: Disclosed is a method of preparing a resin-containing asbestos diaphragm. The diaphragm is prepared by depositing asbestos fibers and resin from an aqueous slurry onto a liquid permeable cathode and subsequently heating the deposited asbestos fibers and resin to cause the resin to bond the asbestos fibers together. As disclosed, air flow is maintained through the diaphragm until the diaphragm is substantially free of entrained water. The heated air is maintained at a temperature below the boiling temperature of entrained water so as to avoid boiling the entrained water.Thereafter, the temperature of the deposited diaphragm is heated to cause the resin to bind the asbestos fibers together.
