Description
Technical field
The utility model relates to a kind of reference electrode, relates to a kind of employing galvanic protection mode peculiar to vessel specifically and carries out the two of anti-corrosion of metal and ooze copper/copper/saturated copper sulphate reference electrode, belongs to the survey instrument field of metallic corrosion protection.
Background technology
Electropotential is the notion of electrochemical theory; the electrical method protection is the Application Areas of electrochemical theory on industrial technology; according to electrochemical theory; when metal is in electrolyte environment (as water; soil) in the time of in; ion motion in metal and the medium produces polarization process and forms electropotential; because the composition of material; foreign matter content; mechanical stress; the acid base concentration of medium; temperature humidity; the reason of each species diversity such as ventilation property; the positive column that metal electropotential difference everywhere, current potential are negative and the cathodic area of current potential calibration constitute galvanic cell, form the galvanic circle by medium; constantly carry out the electronic and ionic exchange; to making the positive column constantly lose metal, produce corrosion (theory and research practice prove that this is the most general most important reason of metallic corrosion); the cathodic area is not then corroded, and is protected.Electrical method protection is exactly that method with technology makes and is embedded in metal structures underground or desire protection under water and becomes negative electrode, for realizing protecting the relative thing (being generally " supplementary anode ") that is provided with to become anode, exchanges not corroding of protected object for the corrosion of relative thing.Galvanic protection is the electrochemical metal anticorrosion technique of widespread use; reference electrode is indispensable measurement and a monitoring tools in the galvanic protection; it mainly acts on is that electropotential for measuring object provides benchmark; to obtain quantitative, comparable measuring result, as the foundation of judging and monitor protected metal structures corrosion situation.Copper/copper/saturated copper sulphate reference electrode is the survey instrument a kind of commonly used that is widely used in metallic corrosion protection (galvanic protection mode) field; because existing copper/copper/saturated copper sulphate reference electrode is relatively more responsive to chlorion; when in ocean environment, using, can be subjected to the pollution of chlorion; the precision of electrode potential and the stability that can cause measuring are under some influence; so in the ocean iron and steel structures cathode protection technology that with boats and ships is representative, copper/copper/saturated copper sulphate reference electrode is not used.
