The titanium anode plate with the noble metal combined coating solves the problem of anode corrosion in a chloride-sulfate mixed system and extends the service life of the titanium anode, and is suitable for producing metal materials such as nickel, cobalt, copper and the like through hydrometallurgical electrolysis.
Description
Technical field
The utility model belongs to hydrometallurgy electrolysis tech field, is specifically related to a kind of titanium anode plate with precious metal combination coating.
Background technology
The electrolytic solution of existing hydrometallurgy electrolysis tech has three kinds of systems: sulfate system; Chloride system; Muriate and vitriol mixed system.In actual production as the anode material seriously corroded of hydrometallurgy electrolyzer; Prior art has solved the anodic corrosion problem of unitary system through adopt Ru (ruthenium) or Ir (iridium) muriate coating at titanium anode plate, but fails so far to solve for the anode material etching problem of mixed system.Precipitated oxygen when problem is in sulfate system anode working; In chloride system, only separate out chlorine during anode working; But in mixed system, should separate out chlorine again by precipitated oxygen during anode working; Therefore, prior art can not solve the anodic corrosion problem in the mixed system, causes anode very short work-ing life.
The utility model content
The technical problem that the utility model solves: a kind of titanium anode plate with precious metal combination coating is provided; Solve the anodic corrosion problem in muriate and the vitriol mixed system; Prolong titanium anodic work-ing life, be applicable to metallic substance such as hydrometallurgy electrolysis production nickel, cobalt, copper.
The technical scheme that the utility model adopts: a kind of titanium anode plate with precious metal combination coating; Has the titanium base material; Said titanium substrate surface scribbles the ru oxide coating successively, molybdenum oxide coating, tantalum pentoxide coating and titanium oxide coating, iridium oxide coating and palladium oxide coating.
Said ru oxide mixes the back brushing and forms undercoat on the surface of titanium base material with tackiness agent; Molybdenum oxide, tantalum pentoxide and titanium oxide mix the back brushing respectively with tackiness agent and form inter coat on said internally coated surface, and iridium oxide mixes the back brushing respectively with palladium oxide and tackiness agent and forms top coating on the surface of said inter coat.
The thickness of said undercoat, inter coat and top coating is 8 μ m-10 μ m.
The utility model compared with prior art adopts precious metal combination coating on titanium anode plate; Solve the anodic corrosion problem in muriate and the vitriol mixed system; Prolong titanium anodic work-ing life, reduced bath voltage, reached energy-conservation and the effect that improves output; Greatly reduce production cost, be applicable to metallic substance such as hydrometallurgy electrolysis production nickel, cobalt, copper.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
A kind of embodiment of the utility model is described below in conjunction with accompanying drawing 1.
A kind of titanium anode plate with precious metal combination coating has titanium base material 1, and said titanium base material 1 surface scribbles the ru oxide coating successively, molybdenum oxide coating, tantalum pentoxide coating and titanium oxide coating, iridium oxide coating and palladium oxide coating.Ru oxide RuO2 mixes the back brushing and forms undercoat 2 on the surface of titanium base material 1 with tackiness agent; Molybdenum oxide MoO3, tantalum pentoxide Ta2O5 and titanium oxide TiO2 mix the back brushing respectively with tackiness agent and form inter coat 3 on the surface of said undercoat 2, and iridium oxide IrO2 mixes the back brushing with palladium oxide PdO respectively with tackiness agent and forms top coating 4 on the surface of said inter coat 3.The thickness of said undercoat 2, inter coat 3 and top coating 4 is 8 μ m-10 μ m.
The utility model adopts multilayer layered coating method, forms three-dimensional gradient combination coating on the surface of titanium base material, makes to analyse oxygen and analyse chlorine and on different aspects, carry out.Anode when work skin have oxygen evolution potential, low chlorine evolution potential, thereby be mainly and analyse the chlorine reaction, or be that high valence state has stoped interior chromatography chlorine with oxychlorination has been avoided the galvanic corrosion of internal layer.Inter coat has played the membrane sepn effect, makes organism can not get into internal layer, thereby has improved electrode life.The internal layer oxygen evolution potential is very low, is mainly oxygen evolution reaction, and the titanium base material has outstanding erosion resistance in addition, has solved the problem in work-ing life of anode material in the mixed system.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
Claims (3)
1. one kind has the titanium anode plate that precious metal makes up coating; Has titanium base material (1); It is characterized in that: said titanium base material (1) surface scribbles the ru oxide coating successively, molybdenum oxide coating, tantalum pentoxide coating and titanium oxide coating, iridium oxide coating and palladium oxide coating.
2. titanium according to claim 1 is coated with the iridium positive plate; It is characterized in that: said ru oxide mixes the back brushing and forms undercoat (2) on the surface of titanium base material (1) with tackiness agent; Molybdenum oxide, tantalum pentoxide and titanium oxide mix the back brushing respectively with tackiness agent and form inter coat (3) on the surface of said undercoat (2), and iridium oxide mixes the back brushing respectively with palladium oxide and tackiness agent and forms top coating (4) on the surface of said inter coat (3).
