Rapid degradation of the anti-corrosion coating on urban lamp posts
Thread Content
The image below shows a street lamp post in a northern city; after about 2 years of use, the anti-corrosion coating on its metal surface has suffered severe rusting. The anti-corrosion material is polyurethane anti-corrosion paint; the surface protective coating is thin and there is no primer, and the design of the lamp post structure is unreasonable. It causes the anti-corrosion coating to fail prematurely, affecting the service life and aesthetic appearance of the lamp post. This incident serves as a reminder to anti-corrosion engineers to carry out their tasks as required, to do their work properly, and to prevent situations like this from occurring.
After 2 years of use in northern cities, the lamp posts experienced rapid damage to their anti-corrosion coating due to the thin layer of polyurethane anti-corrosion paint, the absence of an undercoat, and poor design. This suggests that corrosion prevention engineers need to follow standards strictly to ensure quality and avoid such problems. .
