Abstract:
1. A method for fabricating a sheet-shaped electrode for an electrostatic coalescing device, said electrode comprising a sheet-shaped conductive member of electrically conductive material at least partially enclosed by an insulation of electrically non-conductive material, the method comprising: arranging in an envelope, a layered material structure comprising at least an electrically conductive layer for forming the conductive member of the electrode and two electrically non-conductive insulation layers, which comprise thermoplastic or thermoset material, for forming the insulation of the electrode, said conductive layer being arranged between said insulation layers; sealing the envelope and thereafter evacuating gas from the envelope so as to thereby draw entrapped gas out of the material structure arranged in the envelope; heating the material structure to a temperature above the melting temperature of said thermoplastic material or above a curing temperature of said thermoset material so as to consolidate the material structure while keeping it inside the evacuated envelope; and cooling the material structure and removing the material structure from the envelope before, during or after said cooling to form the a sheet-shaped electrode for an electrostatic coalescing device and comprising a sheet-shaped conductive member of electrically conductive material at least partially enclosed by an insulation of electrically non-conductive material, wherein the material structure arranged in the envelope comprises a semiconducting layer arranged on at least one side of the material structure surface-to-surface with the outwardly facing surface of the associated insulation layer.
