Description

Electrolytic cell is measured in a kind of ooze galvanic corrosion
Technical field
The utility model relates to electrolytic cell, and electrolytic cell is measured in particularly a kind of ooze galvanic corrosion.
Background technology
At present, the general electrolytic cell that adopts three-electrode system is measured in the galvanic corrosion of seawater, but for ooze, common electrolytic cell often can not satisfy the needs of corrosion measurement.Ooze refers to by the saturated marine bottom sediment of seawater, and its physical and chemical performance and seawater have bigger difference, also is different from the physical and chemical performance of general soil.Therefore when the electrochemical corrosion performance of measuring metallic materials in ooze, must consider this property of ooze.The electrolytic cell of common three-electrode system mainly is the measurement that is applicable to the seawater medium, can not well arrange the relative position between the electrode in the ooze medium.In addition, in order to guarantee the accuracy of measurement result, must keep this special physicochemical performance of ooze.Simultaneously, because the nonflowing character and the glutinousness of ooze itself, when measuring the chemical property of different oozes, the ooze sample in the electrolytic cell is changed also quite trouble.Common sheet auxiliary electrode can not reach uniform electric force lines distribution when electrochemical measurement, thereby has influence on the result of measurement.
The utility model content
In order to solve the weak point of above-mentioned three-electrode system electrolytic cell, the purpose of this utility model be to provide a kind of and satisfy the corrosion measurement requirement, improved auxiliary electrode, the ooze sample changes ooze galvanic corrosion easily and measures electrolytic cell.
The purpose of this utility model is achieved through the following technical solutions.
The utility model comprises working electrode, auxiliary electrode, salt bridge, described working electrode is fixed on a side of electrolytic cell by second gland, auxiliary electrode is fixed on the another side of electrolytic cell by first gland, the concave surface alignment work electrode of auxiliary electrode, its height is identical with the height of working electrode; Salt bridge is installed on the top cover of electrolytic cell and with working electrode and is connected.
Wherein: described salt bridge is the right-angle type capillary pipe structure; All have bolt on described first gland, second gland; The auxiliary electrode of described platinized platinum is a circular arc.
Advantage of the present utility model and good effect are:
Be equipped with bolt on two glands of the present utility model, gland and bolt have been formed dismountable unitized construction, and then have solved the shortcoming of ooze measurement medium replacing trouble, can change different oozes quickly and easily; Can also well arrange work simultaneously relative position between electrode, auxiliary electrode and the contrast electrode; When same medium is measured, can change working electrode fast.In addition, the utility model has improved the shape of auxiliary electrode, adopts the platinized platinum auxiliary electrode of circular shape, can overcome the uneven shortcoming of electric force lines distribution in the ooze medium, make that the electric force lines distribution at position is more even between working electrode and the auxiliary electrode, make the more approaching reality of measurement result.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in drawings, the utility model comprises working electrode 2, auxiliary electrode 3, salt bridge 7, in order to reduce between contrast electrode and the working electrode 2 because the error that the dielectric resistance of ooze causes, the salt bridge 7 that connects contrast electrode is improved, salt bridge 7 can be the right-angle type capillary pipe structure, and is installed in by rubber plug on the top cover 8 of electrolytic cell 1.Working electrode 2 is fixed on a side of electrolytic cell 1 by second gland 5, the concave surface alignment work electrode 2 of circular arc platinized platinum auxiliary electrode 3, and adjust and highly to make the height of itself and working electrode 2 suitable, draw by the platinum filament lead then, be fixed on the another side of the electrolytic cell 1 relative by first gland 4 with working electrode 2.All have bolt 6 on first gland 4, second gland 5, so that dismounting and installation.Salt bridge 7 is connected with working electrode 2.
When carrying out electrochemical measurement, second gland 5 is taken off, the measuring media ooze is packed in the electrolytic cell 1, and then push down working electrode 2 with second gland 5, and fixing with bolt 6.Install auxiliary electrode 3 and the salt bridge 7 that has contrast electrode more successively, each lead is connected and can measure with surveying instrument.During the electrochemical properties of the different operating electrode under measuring same medium, can the bolt on second gland 56 is loosening, change working electrode 2 fast, bolt 6 is tightened got final product again.
Its measurement result more approaches reality.
