Background technology
Hydrometallurgy has resource strong adaptability, and the advantages such as cleaner production are widely used in the smelting of the metals such as Cu, Zn, Mn, Ni, Co, and in galvanic deposit production metal process, alloy lead anode is main anode material.Because the electric conductivity of Pb alloy itself is low, matter is soft and density is large, makes traditional alloy lead anode show following characteristics in application process: 1) poorly conductive of pole plate, resistance are high.Make the resistance drop of anode high on the one hand, thereby improve bath voltage, increase energy consumption; On the other hand, due to the large (>1m of polar plate area
2), low electrical conductivity makes the distribution of current of polar board surface inhomogeneous, and pole plate everywhere degree of polarization differs, the highest at the degree of polarization of electrolytic solution/air intersection, and seriously corroded is one of reason causing by pole plate " disconnected neck "; 2) mechanical strength of pole plate is not high, adds pole plate own wt large.Cause on the one hand pole plate creep extension, thereby destroy the stable oxide film protection layer that polar board surface generates, increase the corrosion of anode, thereby shorten anode life, reduce cathode product quality; Easily there is buckling deformation in pole plate on the other hand, causes anode and cathode short circuit, makes anode perforation, and negative electrode burns plate, thereby have a strong impact on work-ing life and the electrolysis energy consumption of anode.
For addressing the above problem, someone proposes at preparation stratiform composite anode, at better other metal or alloy (claiming to conduct electricity central layer at this) of anode interior compound mechanics performance and conductivity.But be all to embed conduction central layer at positive plate internal mechanical, and then together with traditional tab welding of casting in advance.There is following defect in this structure: 1) material of the general use of conduction central layer is Al or Ti, is difficult to form metallurgical binding with lead.The embedding of machinery, cannot ensure on the one hand the excellent electric contact of central layer and outer lead alloy, cannot bring into play collecting and the effect of conduction current of central layer completely; On the other hand, central layer and outer lead alloy cannot form metallurgical binding, make between two-layer relative slippage easily occurs, and creep extension still may occur outer lead alloy, does not have the object that improves mechanical property.2) conduction central layer is not directly connected with the bus (copper rod) in lug.The electric current that the central layer that makes on the one hand to conduct electricity collects still needs to rely on lead alloy conduction to enter the copper rod in lug, thereby can not bring into play the feature that this structure anode improves pole plate conductivity, reduces pole plate resistance drop completely; On the other hand, because the conduction central layer of satisfactory mechanical property is not directly connected with copper rod, can there is tensile deformation in the lead alloy of transition section under the effect of bottom pole plate gravity, can not reach the object that this structure anode improves pole plate mechanical strength, reduces distortion.If electrolytic solution/air interface is positioned at transition section, the problem of " disconnected neck " will still exist.
In sum, tradition lead anode weight is large, there is the defect that electric conductivity is low, matter is soft, the compound slab anode that prior art proposes for the problems referred to above exists conduction central layer can not directly be connected with the conduction plug in lug, and conducts electricity central layer and outer lead alloy and cannot form the shortcoming of metallurgical binding.
