Abstract

The invention discloses an electrochemical reaction still with openings in two sides and a using method thereof. The reaction still comprises a first bottom cover, a first pressure plate, a first polytetrafluoroethylene inner container upper cover, a tank body, a polytetrafluoroethylene inner container, a second polytetrafluoroethylene inner container upper cover, a second pressure plate, a second bottom cover, an electronic conducting device and a four-point bending clamp. The device adopts the polytetrafluoroethylene inner container, has the characteristics of resisting acid and base and resisting the corrosion of various organic solvents, and provides conditions for simulating electrochemical corrosion behaviors under various conditions. The openings are formed in two ends of the tank body, electrode fixing threaded holes for connecting three electrodes are formed in the polytetrafluoroethylene inner container upper cover in one side and can be used for electrochemical tests, and the polytetrafluoroethylene inner container upper cover in the other side is provided with a water inlet, a water outlet and a pressure gage and can be used for injecting a reaction solution and carrying out pressure treatment. The device gives consideration to the electrochemical tests and coupon corrosion experiments which are effectively combined, and can be used for researching corrosion behaviors of metals under high temperature and high pressure environments.

Description

technical field [0001] The invention relates to an electrochemical test device, in particular to an electrochemical reaction kettle with openings on both sides and a use method thereof. Background technique [0002] Corrosion of metal refers to the deterioration and destruction caused by chemical or electrochemical interaction with the surrounding medium in the natural environment or under working conditions. With the gradual development of industry, the various industrial environments in which metals are located tend to be more complex, such as the water-hydrogen sulfide corrosion environment of oil transportation pipelines, the high-pressure chloride ion environment of deep-sea pipelines, the high-temperature and high-pressure environment of boiler pipes, etc. [0003] At present, the research on corrosion mainly focuses on the normal temperature and pressure, and the research on the corrosion environment of high temperature and high pressure is less. Especially in the en...

AI Technical Summary

Problems solved by technology

However, the material has poor corrosion resistance to aggressive ions (chloride ions) in a high-temperature and high-pressure environment, and pitting corrosion is prone to occur on the inner wall of the autoclave, resulting in a great safety hazard

Therefore, for the traditional high temperature and high pressure reactor, it is not suitable for the simulation of today's complex and harsh industrial environment
