Description
Technical field
A kind of preparation facilities of anticorrosion work electrode in simulated solution is the utility model is related to, belongs to electrochemical technology field.
Background technology
Electrochemical corrosion measurement will often use three-electrode system, i.e., by working electrode, reference electrode and auxiliary electrode group
Into electrode system.Metal material species, insulation-encapsulated method, electrode surface state etc. are electrochemical for the corrosion occurred on electrode
The reappearance influence for learning reaction and measurement is very big.Basic demand to working electrode is as follows：
（1）There is the exposed area of determination, in order to accurate calculating current density.Determined in order that working electrode surface has
Exposed area, and in order that the inactive face of test piece is isolated with electrolyte solution, to carry out approved sample.
（2）In order to ensure the reappearance of experimental result and comparativity, the working surface of working electrode should be bright and clean, no dirt,
No oxided film.
（3）The shape of working electrode and the configuration in simulated solution, electrode surface electric force lines distribution should be made uniform.
（4）Electrode ensures no mechanical stress and thermal stress when installing.
Approved sample often produces the problems such as gap, severe jamming experimental result.For example, it is commonly used during metal electrode approved sample
Epoxy resin reinforcing agent, because the epoxy resin fragility after solidification is larger, easily occur naked eyes between resin and electrode test piece
Imperceptible micro chink, after immersing in solution, especially after anode polarization, it may occur that crevice corrosion, gap is broadened, from
And bring test error.For another example metal testing plate press-in internal diameter is slightly less than in the teflon sleeve of test piece external diameter, heating makes
Polyfluortetraethylene pipe shrinks, and tightly wraps electrode test piece, the test piece so encapsulated is not susceptible to crevice corrosion, but electrode face
It is more difficult parallel with auxiliary electrode.
The content of the invention
Above-mentioned existing for working electrode in order to solve the problems, such as, the utility model, which is provided in a kind of simulated solution, corrodes work
Make the preparation facilities of electrode.
The technical solution of the utility model is as follows：The preparation facilities of anticorrosion work electrode in a kind of simulated solution, including water
Flat workbench, working electrode, PVC plastic pipe, first clamping plate and second clamping plate.
Working electrode is placed on horizontal table, working electrode overcoat PVC plastic pipe；Post the lower surface of working electrode
Double faced adhesive tape, it can be pasted onto on horizontal table；There is a pad upper surface of working electrode, and wire one end is welded on working electrode
Pad on；There is wire sheath on wire；Space between working electrode and PVC plastic pipe is filled with epoxy resin；PVC plastic
The outer both sides of pipe have first clamping plate and second clamping plate to be clamped.
The height of the PVC plastic pipe is higher than working electrode, and the epoxy resin of filling can cover the welding on working electrode
Point and part wire sheath, can guarantee that the non-working surface of working electrode, including extraction wire insulating properties are good.
The PVC plastic pipe both ends all need polishing smooth, and PVC plastic pipe stands up seamless on horizontal table.
The beneficial effects of the utility model are that working electrode prepared by the utility model device, will not after anode polarization
Generation crevice corrosion, requirement of experiment can be met.
The utility model device is prepared suitable for working electrode.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure, 1 is horizontal table, and 2 be first clamping plate, and 3 be pad, and 4 be working electrode, and 5 be that working electrode works
Face, 6 be wire, and 7 be wire sheath, and 8 be PVC plastic pipe, and 9 be second clamping plate, and 10 be epoxy resin.
Embodiment
Specific embodiment of the present utility model is as shown in Figure 1.

4th, PVC plastic pipe 8, first clamping plate 2 and second clamping plate 9.
The upper level of horizontal table 1 of the present embodiment puts PVC plastic pipe 8, has a job electric in the PVC plastic pipe
Pole 4, the working face of the working electrode 4 sealed with double faced adhesive tape and it is horizontal positioned on the table；The working electrode 4 it is another
Face copper conductor 6 is welded and drawn outside PVC plastic pipe 8；There are first clamping plate 2, second clamping plate 9, institute in the both sides of PVC plastic pipe 8 respectively
State the full epoxy resin 10 of PVC plastic pipe gap filling.
Its specific implementation step is as follows：
（1）The polishing of the both ends of PVC plastic pipe 8 is smooth, it is stand-by；
（2）A bit of insulation epidermis is cut at the both ends of copper conductor 6 respectively, exposed part polishing, removes oxide film dissolving；
（3）Working electrode 4 is polished light, whether copper conductor welds with non-working surface, turned on universal meter measuring electrode；
（4）By the smooth pvc pipe bottom rubber belt sealing of above-mentioned polishing so that pvc pipe is stood upright on horizontal table, will
The metal electrode that wire is welded is in pvc pipe center, waits the encapsulated electrode of epoxy resin 10；
（5）Prepare epoxy resin；
（6）Between the encapsulation liquid prepared is poured into the above-mentioned electrode pvc pipe fixed, when epoxy resin just spill-over
Untill, stand 24h and wait to do；
（7）The working face of polishing working electrode.
