Electro-osmotic movement of polar liquid in a porous structural material

Abstract

Abstract Reinforcing or carrier elements for plaster are used as electrodes in electro-osmotic dehumidification installations. The elements comprise a carrier body constituted by a flexible net having a surface of synthetic resin in contact with the plaster and the net has filamentary carrier materials incorporated therein. The synthetic resin is a conductive, essentially ion-free thermosetting resin of macromolecular structure, preferably an at least partially cross-linked acrylate polymer having a high surface roughness and containing a small amount of a plasticizer, and forms either the matrix or a coating of the flexible net. The filamentary carrier materials may be carbon or metal filaments. In the use of the dehumidification installation, a voltage alternating between a positive and a negative potential is conducted between the cathode and the anode, the time interval of the positive potential exceeding that of the negative potential.
