ABSTRACT:
A capping board made of plastic material reinforced with fiberglass, for supporting the ends of a plurality of electrodes immersed in an electrolytic cell such as the cells used for the electrolytic refining of copper. This capping board is made of a plastic resin selected from the group consisting of polytetrafluoroethylene and acid resistant polyesters, vinylesters, epoxy and phenolic resins, and contains from 10 to 20% by weight of fiberglass, from 2 to 10% by weight of silica, from 2 to 10% by weight of mica and from 2 to 10% by weight of feldspar. Preferably, at least one wooden core is embedded in the capping board in order to reduce the quantity of resin required and the fabrication cost. Such capping boards made of reinforced plastic material allow for substantial increase in the productivity of electrolytic metal refining plants, in particular because they are resistant to corrosion and do not need to be frequently replaced.
