Anti-Corrosion Solution for Steel Structures in Chemical Plant Buildings

Do you know how to choose coatings in high-salinity and high-humidity environments? Under conventional anti-corrosion systems, the average lifespan of steel structures in chemical plant buildings is only 10–15 years. More than 50% require refurbishment within two years, and 20% show significant corrosion within five years. The underlying reasons may be inadequate coating technology or cost-driven choices. However, the maintenance cost has reached 15%–20% of the initial investment, posing a serious threat to production safety.

The failure of traditional anti-corrosion systems is primarily due to two reasons. First, basic anti-corrosion materials have poor weather resistance and struggle to withstand acidic and alkaline media, organic solvents, and temperature-humidity fluctuations in chemical environments. Second, cost-driven thin-film application techniques fail to provide comprehensive protective capabilities. To break the cycle of “short-term maintenance – repeated corrosion,” a long-term protective system based on material innovation must be established.

To address this, we recommend a globally proven anti-corrosion solution: “Graphene-Based Low-Surface Preparation Primer (180μm) + Polyurethane Elastic Topcoat (60μm),” ensuring maintenance-free protection for over 10 years. The graphene primer, with its two-dimensional layered structure, creates a labyrinth effect that directs electrons away from the metal surface, blocking electrochemical corrosion pathways. Its salt spray resistance is over three times that of traditional zinc-rich epoxy primers. Our self-developed polyurethane topcoat exceeds national standards by 2.5 times in key indicators such as weather resistance and impact strength, effectively resisting UV aging, chemical splashes, and mechanical wear. The system achieves an adhesion strength of 12MPa and maintains structural stability in conditions ranging from -40°C to 120°C. After three years of field monitoring, the coating integrity remains above 98%, and the total lifecycle cost is reduced by 42% compared to traditional solutions.

Choosing this solution not only lowers operational and maintenance costs but also provides strong protection for production safety and asset value.
