Description
Technical field
The utility model relates to a kind of encapsulating structure of contrast electrode, refers more particularly to a kind of encapsulating structure of Composite Double contrast electrode, belongs to impressed current cathodic protection field.
Background technology
Due to the existence of chlorion, dissolved oxygen DO and drying and watering cycle, ocean is for metal construction, it is a kind of harsh corrosion environment, metallic structures in marine environment must take suitable safeguard procedures to avoid corrosion and damage, need to detect the etch state of metal construction simultaneously, and carry out the safety assessment of metal construction according to testing result.At present, it is the effective ways preventing metallic structures marine corrosion that cathodic protection and coating combine, and in order to corrosion and the conservation status of accurate analysis metallic structures, needs the surface potential of Measurement accuracy metallic structures.
Contrast electrode is a kind of reference electrode for measuring metal current potential, and current potential own is stablized and not easily polarization or passivation.
The kind of contrast electrode has a lot, and often kind of contrast electrode has certain scope of application, and has different serviceable life under environment for use.
In cathodic protection, the normal contrast electrode adopted mainly contains copper/copper sulfate eletrode, high purity zinc electrode and silver/silver chloride electrode three kinds; wherein copper/copper/saturated copper sulphate contrast electrode is mainly used in the potential measurement of works in the soil such as underground pipeline; portable type measuring electrode is can be used as in Seawater; because serviceable life is shorter in Seawater, be therefore not suitable for use in fixed type reference electrode.
High purity zinc electrode adopts high purity zinc or kirsite, has longer serviceable life, but its potential drifting is comparatively large, and potential stability is poor.Silver/silver chloride and Ag/AgX contrast electrode are the good a kind of contrast electrodes of performance in Seawater, there is the longer life-span, potential stability is better than high purity zinc electrode, but preparation method and technique have a great impact its performance, there is very large difference in the performance of silver/silver chloride reference electrode prepared by different process method.
In impressed current cathodic protection system; contrast electrode except be used for monitor metallic structures conservation status except; also can be constant potential opertaing device and control comparison signal is provided; if contrast electrode occurs abnormal; potentiostat measuring-signal mistake will be caused; cause potentiostat output abnormality, works may be caused to can not get effective protection, also may produce overprotection and affect the safety of works.Therefore the accuracy of contrast electrode potential measurement, stability and directly have influence on the cathodic protection effect of works serviceable life.For the marine structure that jacket etc. needs digital preservation decades, in order to improve reliability and the accuracy of measurement result, in Practical Project, needing the advantage in conjunction with two kinds of contrast electrodes, using composite reference electrode.
Except the selection of contrast electrode type, contrast electrode structural design also has larger impact for the accuracy measured and long-term reliability.Selection and the mounting structure of hull contrast electrode type used is given in " GBT7387-1999 contrast electrode peculiar to vessel technical conditions " specification, but the situation being single contrast electrode provided, and overhaul because boats and ships regularly can return dock, therefore this specification requires 6 years or 10 years the service time to contrast electrode, and mounting means is also optimized design for Ship Structure.
To jacket class formation thing in Yu Haiyang, the version of jacket and working environment also determine the version of contrast electrode and designing requirement has its singularity, high and the maintenance difficulty of such as maintenance cost causes greatly can not carrying out changing and safeguarding in the phase under arms, therefore usually requires that the serviceable life of contrast electrode and the encapsulating structure thereof adopted reaches more than 20 years.The case that existing contrast electrode lost efficacy in Practical Project at present, in the corrosion monitoring therefore for life-span longer marine structure, the Structural Design Requirement for contrast electrode is very high.
