CONFUR make Bi-Polar Electro Cleaners are used to remove lubricant residues from drawn wire surface, there are number of methods to be used for lubricant removal. One of which include the use of batch dipping either in acid or alkaline solutions or the material pass through tanks containing chemicals. To increase the reaction speed the agitation or the temperature is increased of the treatment solution. The other method used is electrolysis. Further, the two ways supplying electrical current to the running wires is with mechanical contact or Bipolar cell. The higher the current used the faster the material is cleaned or dissolved. The limiting factors in high current application the thickness of diffusion is considered most important, therefore to decrease its thickness the flow rate of electrolyte along the surface is increased. At the time of electrolysis the gas will evolve at both the electrodes which should be removed immediately. Higher the voltage used the more gas is evolved. By reducing the distance between electrodes lower voltage is used at higher currents. It consists of two electrodes of insoluble metal placed in two chambers with a slotted wall in between. The electrodes are placed at a distance from the wire and it is pumped into the cell and electrodes are connected to a D.C source. Further, the wire becomes the opposite polarity as compared with the electrode. It shows that the wire surface is cathodic in the anode section and anodic in the cathode section.
