The present invention relates to a power line anti-corrosion method suitable for use in a highly corrosive environment, and more particularly to a sacrificial anode principle, that is, a cathodic rust method (catholic) as described in electrochemistry. Protection), effectively preventing the resin from being corroded and electrically connected to the environment of the gas or water environment, to achieve the protection of the internal structure and operation of the machine in the gas or water environment, and the safety of personnel operation. .

Press, usually at the dock where the vessel is staying, there will be different wire configurations to allow current to flow through the water, such as the power outlets installed at the beach, electrical appliances, batteries, or the stern current leakage caused by the hull. Etc., and these currents will cause galvanic corrosion of the metal of the hull by seawater. This is because seawater is one of the best conductors of electro-erosion; in addition, the current domestic underground pipelines have been buried for a long time. For a long time, the problem of aging corrosion has become more and more serious. The reason is not only the poor construction quality, but also the increasingly complicated soil environment around the pipeline or the incorrect concept of corrosion during construction. Furthermore, Taiwan The special high-temperature and humid climate combined with the mixed soil with mixed sea sand and various factors of poor construction quality cause the construction of reinforced concrete and soil to be easily corroded and destroyed. This is due to the chlorine on the surface of the steel in the mixed soil. When the ion exceeds a certain content, the protective passivation film on the surface of the steel bar begins to break, and the steel bar begins to corrode and swell, causing the mixed soil to crack, and then Causing construction damage Bad, especially in circuit pipelines used in chemical plants with high corrosive environments, the corrosion behavior of wires is more severe, and if it is not properly controlled, it will cause a safety hazard.
