Polymer alloy coating has good resistance to wet smoke
Thread Content
The flue gas from the gas heating furnace is desulfurized and discharged into the atmosphere through the flue. The wet flue gas in the flue causes serious corrosion damage to the lining. The seams of the original vitrified bricks were powdered, and the surface of the bricks was powdered. For refinishing 400 micron vinyl glass flake coating loses effectiveness in 1 year. It is good to use polymer alloy coating to prevent corrosion of the flue. Figure 1 shows the inner wall of the flue. Figure 2 shows the powdering condition of the flue, and the coating loses its effect. Figure 3 shows the failure of vinyl glass flake coating. Figure 4 Spraying polymer alloy paint. Figure 5: Apply polymer alloy putty. Finally spray the topcoat. It is conservatively said that it can be used for 4 to 5 years.
If the flue gas temperature is not high, a flue made of fiberglass can be used
When the temperature is between 80 and 90 degrees, the use of vinyl resin glass flakes will not work well. If it is an epoxy or epoxy-modified material, the corrosion resistance and permeability resistance will not meet the requirements.
