The anti-corrosion layer of the concrete structure of the new cooling water tower has a short service life
Thread Content
The picture shows a newly built cooling water tower in an industry. After less than half a year of operation, the anti-corrosion layer on the concrete surface fell off and became ineffective. The main reason is that our construction did not meet the design requirements, the paint film was thin, and the impermeability was not good. Therefore, the following points should be considered for the anti-corrosion of concrete structure cooling water towers:: 1. High humidity environment. 2. Impermeability strength. 3. Erosion resistance. 4. Corrosion resistance. 5. Antibacterial properties. 6. Material selection for strong bonding between primer and concrete structure. The most critical thing is impermeability, erosion resistance and bonding strength.
The best solution for concrete structures should be: Epoxy primer + polyurea + polyurethane (weather-resistant).
It is a good solution for the newly built cooling water tower.
