Introduce: copper ball when in the production of copper anode electrolysis, after will generate a layer of black phosphate film, this is the main feature of copper anode. Anodized black phosphorus film forming speed and combined with status and anode current density, chlorine ion content, additive type and content, continuous casting method and process control of the whole process are closely related. Electroplating process in normal conditions, the anode current density of 0. 4 1. 2ASD drag cylinder electrolytic treatment of phosphorized copper anode surface, to form a layer of uniform and compact with good black phosphate film, this time will be in the best state of anodic dissolution of metal.

Wear resistant steel ball manufacturer to introduce to you: in the production of black film, anode copper ball dissolved to a certain time consumption, take off a layer of black film, to constantly supplement to the copper ball and copper ion balance, black film will form a small amount of normal copper phosphide black mud. If the filter cleaning tank bottom, with a wire brush and scrub of anode copper ball even with concentrated acid soaking, not completely remove the black film, shows high phosphorus contents in the copper anode. In addition the inferior anode containing more impurities, coarse grains are not dense, causing dissolved uneven, formation and black film mixed sludge, this is another kind of sludge.
