Problems solved by technology
[0011] From the above test content and test equipment, it can be seen that the cathodic disbondment test of the anti-corrosion layer involves more detection, the operation is complicated and cumbersome, and the related equipment required is more and scattered , scattered equipment and complex operations will bring inconvenience to the test operators and affect the efficiency of the test
In addition, in order to ensure that the sodium chloride solution soaks the auxiliary electrode and reference electrode when the test tank is heated at a constant temperature, it is necessary to add distilled water to the test tank from time to time to ensure the liquid level, which will cause frequent switching of the constant temperature device and affect the efficiency of the test

The invention relates to an integrated cathodic disbonding test device. The device comprises a voltmeter. The device further comprises a constant temperature box, a guide rail, a drilling unit, a plastic barrel mounting unit, a box cover unit and a main control unit for controlling all the units to work; an opening is formed in the top surface of the constant temperature box; the guide rail is positioned above the opening of the constant temperature box; the drilling unit, the plastic barrel mounting unit and the box cover unit are erected on the guide rail and move along the guide rail; under the control of the main control unit, the drilling unit, the plastic barrel mounting unit and the box cover unit move along the guide rail and carry out related test operation of a cathodic disbonding test; and the constant temperature box is used for constant temperature heating. According to the integrated cathodic disbonding test device, integrated setting is carried out according to test steps and needed equipment, various kinds of equipment can automatically carry out detection and other operations under the control of the main control unit, the automation degree of the cathodic disbonding test device is improved, and therefore, the test efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of pipeline anticorrosion coating detection, in particular to an integrated cathodic disbonding test device. Background technique [0002] In daily life, in order to ensure the long-term reliable use of metal products in harsh environments, the metal surface is usually coated with an anti-corrosion layer such as epoxy powder coating with good anti-corrosion effect and combined with cathodic protection technology to prevent metal corrosion. The principle of cathodic protection technology is to apply an external current to the surface of the metal structure to make the protected metal structure a cathode, so that the electron migration of metal corrosion is inhibited, and the occurrence of corrosion is avoided or weakened. However, if there is a defect in the anti-corrosion layer on the surface of the metal structure, the cathodic reaction will cause the anti-corrosion layer to lose its adhesion and separate f...
