The tubular titanium anode comprises a tubular substrate and a coating, wherein the coating is divided into two parts along the surface of the substrate, each part is separated into two layers; an iridium dioxide layer and a ruthenium dioxide layer coated on the iridium dioxide layer are respectively arranged in the first part from the outside to the inside; and a ruthenium dioxide layer and an iridium dioxide layer coated on the ruthenium dioxide layer are respectively arranged in the second part from the outside to the inside. The tubular titanium anode is a titanium anode with oxygen evolution and chlorine evolution functions, and is good in corrosion resistance.
Description
Technical field
The utility model relates to a kind of tubulose titanium anode, belongs to technical field of electrochemistry.
Background technology
General electrode materials will have good electroconductibility, and pole span changes little, and erosion resistance is strong, physical strength and good processability, and the life-span is long, and expense is low, and electrode reaction is had good electrocatalysis characteristic, and titanium is the metal that can satisfy above composite request at present.
The titanium anode is exactly the anode in the titanium-based metal oxide coating, is widely used in the hydrometallurgy industries such as plating and electrolysis.Coating of metal oxides resistivity on the titanium anode is low, has good electroconductibility (conductivity of titanium own is bad), the chemical constitution of noble coatings is stable, crystalline structure is stable, and electrode size is stable, and solidity to corrosion is good, life-span is long, have good electrocatalysis characteristic, be conducive to reduce the overpotential of analysing oxygen, analysing the chlorine reaction, saves energy.Erosion resistance is strong, can be strong in many corrodibility, and have in the electrolytic medium of particular requirement and work, the matrix metal titanium is Reusability repeatedly.
Electrochemical industry Anodic material is the place of anodic reaction, is the parts of most critical.Anodic reaction mainly is divided into oxygen evolution reaction or analyses chlorine reaction, and analyses oxygen and analyse the coating of metal oxides that the chlorine electrochemical industry generally uses and be respectively iridium dioxide and ruthenium dioxide.Along with adopt in recent years developing rapidly of titanium anode research in the electrochemical field such as metallurgy, pharmacy, how to prepare a kind of anode material of analysing oxygen and analysing the chlorine function that has concurrently, become a problem demanding prompt solution.
The utility model content
The technical problem that the utility model solves is: propose a kind ofly to have the titanium anode of analysing oxygen and analysing the chlorine function concurrently, and have erosion resistance preferably.
In order to solve the problems of the technologies described above, the technical scheme that the utility model proposes is: a kind of tubulose titanium anode, the matrix and the coating that comprise tubulose, described coating is divided into two portions along matrix surface, every part is divided into two-layer, wherein first part is respectively from outside to inside the iridium dioxide layer and pastes ruthenium dioxide layer on described iridium dioxide layer, and second section is respectively from outside to inside the ruthenium dioxide layer and pastes iridium dioxide layer on described ruthenium dioxide layer.
Improvement of the technical scheme is: two portions of described coating are along base shaft to dividing equally.
Further improvement in the technical proposal is: two portions of described coating are circumferentially divided equally along matrix.
The beneficial effect that the utility model brings is: tubulose titanium anode of the present utility model, the outside surface of titanium anode substrate is respectively arranged with coating, and coating is divided into two portions, be respectively from outside to inside the combination of iridium dioxide layer and ruthenium dioxide layer, and iridium dioxide layer and ruthenium dioxide layer have respectively and analyse preferably oxygen and analyse the chlorine function, and therefore tubulose titanium anode of the present utility model can have concurrently and analyse oxygen and analyse the chlorine function; Iridium dioxide layer and ruthenium dioxide layer corrodibility are good, wear-resisting in addition, thereby make the titanium anode tube that very strong erosion resistance be arranged, and can keep out the corrosion of acid, alkali, salt, thereby improve work-ing life.
Description of drawings
Below in conjunction with accompanying drawing, tubulose titanium anode of the present utility model is described further.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
