Corrosion Protection Project Testing for Large-Scale Chemical Storage Tank Area
China·Northwest Base
2023
Facing challenges
The tank farm environment is harsh, with a risk of acid and alkali gas leaks. Additionally, the northwest region experiences large diurnal temperature swings and intense ultraviolet radiation. The outer walls of the storage tanks must withstand the dual challenges of chemical corrosion and physical aging. The customer places particular emphasis on the coating’s resistance to chemicals and its ability to prevent cracking.
Solution
A cutting-edge heavy-duty anti-corrosion solution has been adopted, featuring a combination of “waterborne graphene-zinc primer for heavy-duty corrosion protection + waterborne graphene intermediate coat + waterborne graphene fluorine-containing topcoat.” The layered structure of graphene forms a dense physical barrier network, significantly enhancing its anti-corrosion performance and resistance to chemical penetration. Meanwhile, the fluorine-containing topcoat delivers superior weather resistance and self-cleaning capabilities.
Project outcomes
The project successfully implemented graphene-modified coating technology. Testing has shown that the coating exhibits salt-spray resistance exceeding 3,000 hours. To date, since its operation began, no rust spots have appeared on the surface of the storage tanks, effectively ensuring safe production in the chemical industrial park. The project has been recognized internally within the group as a “high-quality anti-corrosion engineering project.”
