As a major global transportation equipment, containers play an extremely important role in international cargo transportation. Ocean shipping is one of the main modes of container transportation. Ocean shipping containers are used for a long time in the marine environment, especially those loaded on the deck of container ships, which are susceptible to corrosion from the marine atmospheric environment, thereby shortening the service life of containers and increasing maintenance costs. Based on the characteristics of the marine atmospheric environment, combined with the analysis of the principle of metal corrosion caused by the marine atmosphere, the anti-corrosion effect of coatings is applied to reduce the corrosive effect of the marine atmosphere on ocean shipping containers, thereby achieving container protection.
