Technical field
The utility model relates to a kind of ti-lead dioxide anode plate.
Background technology
Along with the development of industry and science and technology, traditional anode material more and more has limitation.For example: the platinum cost is too high, and graphite solidity to corrosion in chlorine industry is poor, and intensity is less; Alloy lead anode solidity to corrosion and conductivity are relatively poor, and energy consumption is larger.From energy-conservation, consumption reduction, so-called " green material " requirements such as pollution-free, we more need energy-conservation, the free of contamination type material anode of catalytic activity height.
The utility model content
The technical problem that the utility model solves: a kind of ti-lead dioxide anode plate is provided, first apply the transition layer that is formed by ruthenium and iridium oxide on the titanium base material, purpose is the passivation that overcomes Ti matrix in long-time electrolysis production process, strengthen the bonding force of PbO2 coating and matrix, prevent that coating from coming off, improve job stability and the work-ing life of PbO2 electrode, and the electroconductibility that improves electrode.Then apply the active layer that is comprised of tin and sb oxide on transition layer, electrolytic solution is difficult to be penetrated into titanium surface, Sauerstoffatom or O again
2-Ion also has been subject to stopping to the diffusion of titanium matrix, thereby has avoided TiO
2Generation.Plating middle layer α lead dioxide plating coat on active layer can strengthen the firmness of lead dioxide plating coat and electrode matrix combination, the generation of mitigation electrodeposition distortion, can also make β-PbO
2Be evenly distributed.
The technical solution adopted in the utility model: the ti-lead dioxide anode plate, have the titanium base material, described titanium substrate surface scribbles ruthenium and iridium oxide coating, tin and antimony oxide coated, α lead dioxide plating coat and beta lead dioxide coating successively.
Wherein, described ruthenium and iridium oxide be coated in the titanium substrate surface after tackiness agent mixes and form transition layer, described tin and sb oxide be coated in the transition layer surface after tackiness agent mixes and form active layer, described active layer electroplating surface α plumbic oxide forms the middle layer, and described interlayer surfaces is electroplated beta lead dioxide and formed serving.
Further, the thickness of described transition layer is 3-5 μ m, and the thickness of described active layer is 3-5 μ m, and the thickness in described middle layer is 30-50 μ m, and the thickness of described serving is 2-3mm.
The utility model has compared with prior art improved the binding force of cladding material of ti-supported lead dioxide electric, improved oxygen overpotential, strengthened the oxidation capacity of anode surface, direct oxidative degradation organism on anode surface, make the organism in sewage pass through electrochemical conversion, direct or indirect CO2 and the water of being converted into can not pollute in this process, is called as Green Water and processes; Strengthened simultaneously the corrosion resistance of titanium matrix, prevented that the titanium matrix surface from forming the poor titanium dioxide of electric conductivity, strengthened the electroconductibility of positive plate.
