Description
Technical field
The present invention relates to mechanical field, particularly relate to the manufacture method of a kind of sheath.
Background technology
Tradition insoluble anode wet method electrodeposition process generally adopts plate and frame structure, the electrolyte participating in electrochemical reaction is slower in negative and positive interpolar flowing velocity, under highfield power effect, electrolyte is very easy between pole plate concentration polarization phenomenon occurs, and causes that non-targeted ion produces side reaction in anode and cathode and reduces the current efficiency of electrochemical process.During for electrolysis water generation concentration polarization phenomenon, solution resistance increases, and electric current plays heat effect to solution by solution and no longer decomposition water；Metallurgical electrodeposition is example in a wet process, and non-targeted cation replaces target cationic and is deposited on negative electrode, reduces cathode product quality.No matter electrolysis or the prime cost of its equipment of electrodeposition all concentrate in the making of insoluble anode, in order to save annode area, under the premise of same anode area, adopt higher anodic current density to become the trend that electrochemical apparatus makes.
The cyclone electrolytic cell technology that the nineties in last century begins one's study, it is by improving electrolyte in interelectrode flowing velocity, eliminate concentration polarization phenomenon, reduce the negative effect that its electrochemical process causes, under geostationary annode area, very high currents intensity is adopted to obtain higher negative electrode production capacity or cathode product quality more preferably.
The insoluble anode being applied to cyclone electrolytic cell is generally made up of outer layer antioxidation washcoat+internal conductive structures, its antioxidation washcoat according to solution anion character unusual by specialty be coated with company complete, and existing patent formed；But then relatively degrees of overtness is little in the making of its internal conductive structures, and the internal conductive structures prepared of existing technique or dependability is low, or complex manufacturing technology, cost are high.
Publication number is the patent of 102758215A: interior contact assembling anode simple structure, initial stage that a kind of Special anode in cyclone electrolyzer is announced use conductive capability strong, but after serving as the tin-phosphor bronze sheet the contacting conduction time about one season of use inside it, due to contact resistance heating and tubular body air oxidation, lose with titanium pipe base material gradually and contact, and finally make whole anode lose conductive capability.
Use the column anode that titanium and copper composite bar material makes, it is impossible to meet the demand of oxide coating coating procedure repeatedly heating and cooling；Use sheath contact resistance prepared by the mode filling copper spring washer in titanium pipe still very big；
In a word, in order to reduce the manufacturing cost of cyclone electrolytic cell process equipment, it is still necessary to study the manufacture method that a kind of reliability is high, electric conductivity is strong, with low cost.
Summary of the invention
The purpose of invention: in order to provide the manufacture method of the sheath of a kind of better effects if.
