Description
Technical field
The present invention relates to non-ferrous zinc metallurgical technology and material antiseptic technical field, more particularly to a kind of band coating
Anti-corrosion zinc cathode aluminum plate preparation method.
Background technology
The minus plate of zinc by wet method is to roll plate with fine aluminium, and positive plate is with lead-silver alloy, lead-silver multicomponent alloy
Manufacture.In process of production, minus plate is submerged in solution of zinc sulfate in a cell with the plate face overwhelming majority of positive plate,
In the presence of direct current, respectively there is discharge depositing in negative electrode, anode, and the zinc in zinc sulfate is deposited the plate for being attached to minus plate

ZnSO4+H2O+еZn+H2SO4+1/2O2
In process of production, beyond the exposed solution of zinc sulfate in a cell of zinc cathode aluminum plate and aluminium sheet two side ends part, by
Acted on F, Cl by sulfuric acid in for a long time, corroded especially severe.Although the negative electrode plate face being immersed in electrolytic cell solution of zinc sulfate
Substantially it is intact, but because of plate face neck and plate face two side ends seriously corroded, it is impossible to it is continuing with, causes minus plate service life short,
Increased production cost.As the reduction of zinc concentrate resource, electrolytic zinc raw material are increasingly complicated, fluorine/chlorine in solution of zinc sulfate is caused
Ion is exceeded, and is fluorine ion to minus plate corrosion impact the biggest factor, therefore causes minus plate extent of corrosion to aggravate.
Patent CN2887892Y is proposed and prevented with one layer of the plate neck surface painting of positive plate in the minus plate of zinc by wet method
The method of rotten layer extends the decay resistance of electrolytic zinc negative and positive machine plate, but is only coated with one layer of epoxy resin or heatproof preserving timber
Material, the extension life-span is partially short, average energy 60 days.
Patent CN201495302U discloses a kind of preparation method of electrolytic zinc anode plate, proposes using naked in pole plate upper end
Seemingly bar is installed at dew position on the electrolyte, and the anti-corrosion bar described in it is made of synthetic material, is installed in pole plate
Top will not be damaged because by the corrosion of severe gas, thus can extend the service life of minus plate.
Patent CN101781780B proposes a kind of method for improving corrosion resistance of cathode aluminum plate for zinc electrolysis, and it is used
Special ROLLING OIL, using conventional two rollers are irreversible, batch (-type) machine is rolled to aluminium, immediately using treatment silicon after rolling
Sour sodium carries out subsequent treatment, obtains the aluminium donkey-hide gelatin plate of surfacing, and larger, the comparatively dense oxide surface layer of generation thickness,
So as to improve its decay resistance.Its service life is set to improve more than three times.
Patent CN102953093A proposes a kind of Zinc electrolysis minus plate anticorrosive coat and preparation method thereof, and it uses spraying
Or the mode of blade coating coats anticorrosive paint, the anticorrosive paint at liquid level line to the position between conducting beam that the negative electrode principal columns of a hall easily corrodes
It is made up of bottom, intermediate layer and top layer.By the use of the corrosion-inhibiting coating, the service life of minus plate substantially can be extended 1/3
~1/2, the replacement frequency of aluminium sheet is reduced, so as to save the production cost of electrowinning zinc, improve productivity effect.
United States Patent (USP) US005498322A is proposed and is made zinc electrolysis minus plate with aluminium alloy, by add magnesium, silicon, iron,
The elements such as copper, zinc, so that cold rolling method is rolled to plate, so as to aluminium alloy plate is obtained, the aluminium sheet of gained improves anti-corruption
Corrosion energy, so as to extend the service life of negative electrode.Aluminium is the active metal of comparing, is easily corroded, and especially electrolytic zinc is used
Minus plate it is exposed outside liquid level line and aluminium sheet two side ends part, previously mentioned anti-corrosion method, all not enough clearly, operative employee
Skill is relative complex, and on how improving resistance to F performance of the zinc cathode aluminum plate to zinc electrolyte, reducing and removing F or zinc cost of material
Do not mentioned more.
In sum, the decay resistance of zinc cathode aluminum plate how is improved, increasing the service life of aluminium sheet, while raising zinc
Cathode aluminum plate is reduced and removes F or zinc cost of material to the resistance to F performances of zinc electrolyte, is the problem for needing further exploration.
