0.5% rosin is uniformly mixed, and adds concentration 18wt% sulfuric acid 1.35g（Addition is the 27% of lead quality）, it is stirred into cream
Shape, obtains lead plaster, by lead plaster extrusion on metal grid, spontaneously dries.Then in 10wt% sulfuric acid solutions, constant current-
5mA/cm2Be metallic lead by the lead oxides in former lead plaster or sulfate conversion when electric current chemical conversion 24 is small, surface apply after lead
Alloy grid is as auxiliary electrode.
（2）Technique for applying flow
It is 160g/LH to configure concentration2SO4And 150g/LZnSO4Electrolyte.The beaker of 2 250mL is taken, is respectively put into
The electrolyte that 200mL is prepared, this 2 beakers are referred to as anode slot and cathode can, then according to Fig. 1 connection circuits, anode slot
Place Pb-Ag alloy electrode（Pb-1wt%Ag）, the pure zine plate of cathode can placement, anode slot placement auxiliary electrode, cathode can is placed auxiliary
Electrode is helped, is connected between the auxiliary electrode of two electrolytic cells by conducting wire.Pb-Ag alloy electrode external power supply in anode slot
Cathode, occurs oxygen evolution and reacts, the zine plate cathode in cathode can connects the anode of external power supply, and metal occurs after energization after energization
The electrodeposit reaction of zinc.Auxiliary electrode occurs to be charged and discharged reaction respectively, after the completion of discharge and recharge, after two auxiliary electrodes exchange
It can be used continuously carry out electrodeposition.It is j=100A/m in current density2Under the conditions of carry out electrodeposition, obtain zinc on zine plate cathode.
Specific embodiment of the present utility model is explained in detail above in association with attached drawing, but the utility model is not
It is limited to the above embodiment, within the knowledge of a person skilled in the art, this practicality can also be not being departed from
Various changes can be made on the premise of new objective.
