Steel structure is a structure composed of steel materials, which is one of the main types of building structures. It is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. Welding is usually used between components or parts. Seam, bolt or rivet connection, widely used in large factories, venues, super high-rise and other fields. Due to the poor corrosion resistance of steel structures, especially in the environment of humid and corrosive media, corrosion problems of steel structures frequently occur. Next, let us understand the causes of corrosion and protective measures.
Cause analysis of steel structure corrosion: Steel is prone to electrochemical corrosion under the action of water, steam, chemically aggressive gases, and acid-base salt solutions. There are many impurities distributed on the surface of the steel. These impurities become cathodes for the metal body due to their high potential, while the metals become anodes. There are many tiny cathodes and anodes on the entire metal surface, and many tiny primary batteries are formed. These tiny primary batteries are called micro-batteries, and the batteries continuously react to generate corrosion products—that is, electrochemical corrosion.
What are the corrosion protection measures for steel structures? If the steel structure is to be used for a long time without extensive maintenance, long-term coating protection is a good choice. Soleil heavy-duty anti-corrosion coating is a high-functionality two-component thermosetting polymer coating. The highly cross-linked structure formed after curing is fundamentally different from other coatings. The coating shows good product performance and anti-corrosion ability: it has Good corrosion resistance against a wide variety of aggressive chemicals, including strong acids, bases, gases, solvents and oxidants; good adhesion and adhesion to metal substrates, composites and concrete; good Flexible stress, abrasion and impact resistance, hydraulic sand cleaning, steam cleaning, online repair, low surface tension; good resistance to cold and heat cycles, ranging from -40°F to +400°F (-40° to 204°C). To sum up, it is a good choice to use Soleil heavy-duty anti-corrosion coating for corrosion protection of steel structures.
