Detachable electrode

Abstract

The invention relates to a detachable electrode, which comprises an electrode cap, an electrode sealing rubber sheet, an electrode test piece, an electrode electrical connection bolt, an electrode fixing bolt, an electrode electrical connection nut, a conducting wire and an electrode backseat, wherein one end of the electrode electrical connection bolt is inserted into the electrode fixing bolt, penetrates through the electrode fixing bolt and is then in thread connection with the electrode electrical connection nut; the electrode cap and the electrode backseat are respectively in thread connection with the two ends of the electrode fixing bolt; the electrode electrical connection nut is accommodated in the electrode backseat; one end of the conducting wire is connected with the electrodeelectrical connection nut, and the other end of the conducting wire penetrates through the electrode backseat to be a free end; and the other end of the electrode electrical connection bolt is sequentially provided with the electrode test piece and the electrode sealing rubber sheet which are accommodated in the electrode cap. According to the invention, a required working electrode can be quickly manufactured within a short time simply and conveniently, and after measurement of an electrochemical test is carried out, the electrode test piece can be separated from an electrode shell and used as a hanging piece to be subjected to surface morphology observation and elemental analysis.

Description

technical field [0001] The invention relates to a working electrode structure for electrochemical testing and measurement, in particular to an electrode test piece that can be separated from the working electrode shell and used as a coupon for surface morphology observation and elemental analysis after electrochemical testing and measurement detachable electrodes. Background technique [0002] At present, in the process of electrochemical testing and measurement, the working electrode is generally welded with the electrode test piece and the wire, and then uses epoxy resin to seal the non-working part of the electrode test piece according to the required electrode working area, or the electrode test piece and the wire It is directly nested in the PTFE shell after welding. In this way of making the working electrode, the manufacturing steps are cumbersome, the process is complicated, and the time is long, and it is easy to cause the manufactured working electrode to fail to ...
