种极生产,是电解铜生产中的重要关键。目前,国内外仍多沿用铜制或不锈钢作阴极母板,未行电解前,其表面须经特殊处理、周边包以绝缘材料或涂腊和表面沾皂剂等工序,然后置于电解槽进行电解获取始极片。该法每道工序均较严细,否则,使电积于母板上的铜难于剥离,则需多花劳动力;铜制和不锈钢母板在电解过程中一遇烧板,铜片更无法剥离,往往使母板不能再用而报废;上述两种板材使用寿命都比较短,铜制母板易受电解液酸
Pole production, electrolytic copper production is an important key. At present, still at home and abroad continue to use copper or stainless steel as the cathode mother board, before the electrolysis, the surface to be specially treated, wrapped around the insulating material or waxing and surface dip soap and other processes, and then placed in the electrolytic cell Electrolytic start pole piece. The method of each process are more stringent, otherwise, so that the electricity on the motherboard difficult to peel copper, you need to spend more labor; copper and stainless steel motherboard in the electrolysis process once the plate, the more can not be peeled copper , Often make the mother board can not be used again and scrapped; The above two kinds of sheet life is relatively short, copper mother board susceptible to electrolytic acid
