Abstract
Improved graphite composite electrodes are provided by rendering the matrix resin conductive by dispersing therein 5 to 15% by weight of a conductive pigment and by uniformly dispersing therein randomly oriented graphite fibers having a diameter below 30 microns and a length no more than 1/2 the thickness of the electrode plate. The electrodes are particularly useful in the disinfection of aqueous liquids with low power consumption and with very low ablation of the surface of the electrode.
Claims20
An electrode comprising a shaped member having an electrode face and a rear face defining a thickness, said electrode comprising a composite of a uniform dispersion of randomly distributed graphite fibers having a diameter from 1 to 30 microns and a length of no more than 1/2 the thickness of the electrode member dispersed in a cured, oxidation-resistant and chemical resistant, continuous matrix resin containing a dispersion of conductive particles selected from graphite and carbon having a diameter smaller than the diameter of the fibers.
An electrolytic cell comprising in combination:
- walls defining a housing having a compartment for receiving a body of electrolyte,
- an anode electrode within the housing having a front face in a communication with the compartment and having a rear face,
- a cathode electrode within the housing having a front face in a communication with the compartment and having a rear face,
- contact means for connection to the rear faces of said electrodes, and
- at least one of said electrodes comprising a composite of a uniform dispersion of randomly distributed graphite fibers having a diameter from 1 to 30 micron and a length no more than 1/2 the thickness of the electrode dispersed in a cured, oxidation and chemical resistant, continuous, matrix resin containing a dispersion of fine, particulate conductive filler having a diameter less than the diameter of the fibers and selected from carbon or graphite.
