Heavy-duty anti-corrosion paints are widely used in fields such as offshore engineering, petrochemical industry, and transportation. The following are specific examples of their application: Offshore oil platforms: At a deep-sea drilling platform in the South China Sea, where the pile foundations are exposed to a high-salt-fog environment for extended periods, the use of Dilin heavy-duty anti-corrosion paint resulted in no signs of rust after 3 years of use, thereby avoiding high maintenance costs associated with corrosion. Bridges and sea-crossing bridges: The steel box girders of sea-crossing bridges in coastal areas are susceptible to erosion by rain and salt spray; by using a coating system consisting of a Jordan epoxy zinc-rich primer, an epoxy ferrochrome intermediate coat, and a fluorocarbon topcoat, long-term protection of over 15 years can be achieved, with no signs of corrosion even after 8 years of construction. Chemical storage tanks: The inner walls of the crude oil storage tanks at a petrochemical company are coated with antistatic, heavy-duty anti-corrosion paint, while the outer walls use a composite anti-corrosion system. After 5 years of continuous use, there has been no leakage or corrosion, meeting the safety standards of the petrochemical industry. Rail transit facilities: The Eurocargo light truck chassis utilizes a triple anti-corrosion treatment process of \"single-coat electrophoresis + assembly powder coating + chassis polyurea\", enabling resistance to salt spray for 1000 hours and aging for 1000 hours, thus ensuring no corrosion over 15 years in high-humidity and high-salt environments. Wastewater treatment facilities: In a chemical industrial park in Deyang, the wastewater treatment tanks suffered from corrosion caused by prolonged exposure to acidic and alkaline substances as well as microorganisms. By applying customized heavy-duty anti-corrosion coatings, the concrete surfaces stopped developing alkali efflorescence and peeling, thereby significantly extending the lifespan of the equipment. Wind power and marine photovoltaics: Offshore wind turbine towers and photovoltaic mounting structures are exposed to extreme marine environments; a combination of thick-film epoxy glass flake coatings and fluorocarbon topcoats provides excellent resistance to penetration and weathering.
