Polymer alloy coatings exhibit excellent performance in resisting humid flue gases

Thread Content

The flue gas from the gas heating furnace is discharged into the atmosphere through the flue after desulfurization. Among them, wet flue gas causes severe corrosion and damage to the lining in the flue. The grout in the existing vitrified tile joints has faded, and the surface of the tiles has faded as well. The repaired 400-micron vinyl glass flake coating loses its effectiveness after 1 year. Using polymer alloy coatings for anti-corrosion on flues yields good results. Figure 1 shows the inner wall of the flue. Figure 2 shows the pulverization of the flue, with the coating losing its effectiveness. Figure 3 shows the failure of the vinyl glass flake coating. Figure 4: Spraying of polymer alloy coating. Figure 5 shows the application of scraped polymer alloy putty. Finally, apply the topcoat. Conservatively, it can be used for 4 to 5 years.
