Description
Technical field
The utility model relates to a kind of hydrometallurgy and uses anode, and especially a kind of lead-steel layered composite electrode belongs to the electrochemical device field.
Background technology
At present; Known anode material is the important equipment device of electrolysis (amassing) metallurgy and electrochemical industry; The title that " heart " in the electrochemical reaction system arranged; It is main with lead base binary alloy (Pb-Ag alloy), lead-based multi-component alloy (Pb-Ag-Sr-Ca alloy) etc. mainly, and LY has good electrochemical, lower use cost and cheap advantages such as recycling.But there is following problem in lead electrode in practical application: 1. the LY internal resistance is big, causes in the electrolytic process energy consumption big; 2. the physical strength of lead electrode is low excessively: in the electrolytic zinc process, under the effect of electrical forces, because plumbous intensity is low, can cause battery lead plate flexural deformation, this not only can destroy the stability of electrochemical reaction, but also can cause intereelectrode short-circuit, causes the burning plate; 3. the local solubility of lead electrode:, cause that lead base body local location is prone to produce PbO in the electrolytic process because the uneven influence of electric current distribution makes the electrode surface local current excessive
2Loose body and progressively come off, form the anode sludge, and the lead that causes part to come off separates out at negative electrode, pollute and separate out product gas purity; 4. alloy lead anode plate quality is big, operation inconvenience.
The utility model content
In order to overcome deficiencies such as existing anode material internal resistance is big, physical strength is low, it is the stratiform composite anode that the utility model provides a kind of NEW Pb-steel, and this anode material not only physical strength is high, and internal resistance is little, solidity to corrosion is good.
The utility model is realized through following technical proposal: a kind of lead-steel layered composite electrode; Comprise conduction Tongliang County, coating layer, the 3rd transition constituent element metal level and inner core; Wherein, Compound successively from inside to outside the 3rd transition constituent element metal level in inner core periphery, coating layer, and in an end arranged outside of combined electrode conduction Tongliang County.
Said coating layer is plumbous or lead 2-base alloy.
Said inner core is steel.
The utility model is started with from the design of basal body structure; Adopt the electrode matrix plan of layered composite structure; Its technological thought is: the inner core of anode substrate utilizes the excellent and light weight of electroconductibility, metallic steel is as the rapid passage of afflux carrier and electric transmission cheaply; Play the purpose that reduces matrix internal resistance, equalizing current density distribution, gains in strength, and solid outer solid-complex method that adopts, and internal layer is introduced the 3rd transition constituent element and is solved plumbous, steel interface combination problem; Prepare leaded steel stratiform composite anode materials, the matrix skin of this electrode has still kept the technical requirements of the original electrochemical properties of LY and original electrodeposition process.
Beneficial effect that the utility model possesses and advantage: characteristics such as this lead-steel layered composite electrode has the physical strength height, bath voltage is low, corrosion resisting property good, light weight.
Owing to adopt the structural design scheme of multilayer metal compound " sandwich " formula, improved the conductivity of electrode, the lead of layered composite structure-steel anode is from overall equivalent electrical circuit; It is the parallel-connection structure of Pb ‖ PbFe ‖ Fe, and its total internal resistance is less than or equal to the internal resistance of steel, and this has improved the quick transmission effects of electronics mobile; It is also the shortest to make that electric current passes through the plumbous path of high resistance; Thereby reach the voltage landing that reduces on the electrode, make electrode reaction speed up, catalytic activity improves; Moreover internal resistance reduces then electropotential and reduces, and reactive loss then reduces; Homogenizing the distribution of current of anode and cathode surface: when lead-steel anode is participated in electrochemical reaction; Electric current at first is to be imported by the inner core steel plate; Because the internal resistance of steel is compared less with lead; Then form the equipotential potential surface at surface of steel plate; These potentiometric contours are passed the LY layer equably with electric energy and are imported electrolytic solution, and until being evenly distributed on the cathode surface, this is to improving current efficiency in the electrolytic process, improving the quality of negative electrode product and slow down the anodic local corrosion direct crucial effects is arranged; Increased the physical strength of lead electrode: adopting steel plate is the intensity that the matrix inner core has increased lead electrode undoubtedly, and this plays a part important support frame to the creep-resistant property that improves positive plate; Alleviated the weight of chloride plate: the density of steel is plumbous 0.7 times approximately, adopts leaded steel compound electrode to reduce than the weight of traditional lead electrode, and this all is useful to the handiness that improves operating process.
