Abstract

The invention discloses a quasi-isostatic pressing electrode sealing structure and a using method thereof. The electrode comprises an electrode base, a tested electrode, an electrode lead and a sealing insulation assembly. The sealing insulation assembly comprises an insulation sleeve and a tightening piece. The insulation sleeve sleeves a second base body and the outer ring surface of the testedelectrode; the tightening piece is arranged on the outer surface of the insulation sleeve in a sleeving mode, in the working state, the testing end of the tested electrode makes contact with fluid, initial sealing is formed through tiny stress generated by the tightening piece, the insulation sleeve is extruded through the pressure of water fluid, and therefore the sealing effect under high pressure is achieved, and the tested electrode is in a quasi-isostatic pressing state. Therefore, the technical problems of inaccurate electrochemical measurement result and limited application range causedby large difference stress of the existing electrode sealing mechanism on the tested electrode are solved.

Description

technical field [0001] The invention relates to a quasi-isostatic electrode sealing mechanism and an application method thereof, belonging to the technical field of electrode sealing. Background technique [0002] In the electrochemical experiment of high temperature and high pressure water fluid, usually the sealing materials such as polytetrafluoroethylene, fluorine rubber, silica gel, epoxy resin and so on have certain plasticity, certain strength and good insulation performance are combined with electrodes to form various sealing materials. A sealing mechanism to complete the sealing and insulation of the electrodes. However, in order to ensure the sealing and insulation of the electrodes, in the various existing high-temperature and high-pressure water fluid electrode sealing mechanisms, a large stress (usually including extrusion force and friction force) needs to be applied to the electrodes. The stress on the material is an important thermodynamic parameter that aff...
