What are the reasons for delamination and peeling of the 4-mm vinyl glass flake coating on the inner wall of the flue gas desulfurization tower after more than 1 year of use?

The peeling and detachment of vinyl glass flake coating on the inner wall of the flue gas desulfurization tower may be caused by the following reasons: 1. Quality issues with the material itself: Vinyl glass flakes may have quality defects such as unevenness or impurities, which make them prone to damage during use. 2. Adhesive and application issues: The adhesive used during application may not provide sufficient adhesion, or the application method may be improper, such as failure to clean the surface thoroughly, resulting in weak bonding. 3. Corrosive environmental impact: The environment inside flue gas desulfurization towers is complex, containing various corrosive chemicals, and vinyl glass flake may not be able to effectively resist these corrosive factors. 4. Effect of temperature changes: Temperature fluctuations inside the tower can cause the material to expand and contract thermally, which may lead to cracking or detachment of the vinyl glass flake. 5. Mechanical wear: Particles carried in the flue gas may cause physical wear on the inner wall of the tower, accelerating the damage and detachment of vinyl glass flake. It is recommended to conduct thorough inspections of the materials and construction, as well as assess the environmental conditions, in order to identify the specific causes and take appropriate corrective actions. .
