The invention provides an anti-
corrosion treatment process for a ship lock inverted-V-shaped door
metal structure. The anti-
corrosion treatment process comprises the following steps that S1, surface pretreatment is conducted on the inverted-V-shaped door
metal structure, and attachments,
rust and other impurities are removed; S2,
coating corrosion prevention is conducted, specifically, a
moisture-curing
coating is sprayed on the inverted-V-shaped door
metal structure, and the spraying thickness is 0.4-1mm; and S3, a direct-current power source and an auxiliary
anode are additionally arranged, the auxiliary
anode is connected with the positive
electrode of the direct-current power source to serve as an
anode, the ship lock inverted-V-shaped door metal structure is connected with the negative
electrode of the direct-current power source to serve as a
cathode, protective current is provided by the direct-current power source, and an impressed current
cathodic protection system is formed. Through the operation, anti-corrosion treatment of the ship lock inverted-V-shaped door metal structure is completed. According to the anti-corrosion treatment process, the comprehensive anti-corrosion technology combining the
coating and impressed current
cathodic protection is adopted, effective
corrosion prevention of the large ship lock inverted-V-shaped door metal structure can be achieved, and the service life of the inverted-V-shaped door metal structure is prolonged.
