Application of glass flake coating and its corrosion resistance
Thread Content
Dear colleagues, our company is engaged in the handling of hazardous waste. For the waste heat boilers used in our operations, shock wave soot blowing is employed; however, the generator tank and the pipes connecting to the outlet of these shock wave soot blowers suffer from frequent corrosion (as shown in the figure below). We have tried using 316L material as well as positive pressure air blasting to address this issue, but neither method has yielded satisfactory results. I’m considering using glass flake coating on the inside for anti-corrosion purposes; I’m not sure what the results will be. Does anyone who knows about this have any suggestions? Thank you!
First, you need to understand why corrosion occurs and why damage happens. My shock wave soot blowers didn’t fail for seven or eight years; I’m not sure what’s the case with yours
The glass flake coating offers good resistance to chemical corrosion and high temperatures, making it suitable for anti-corrosion applications. Before applying glass flake coating, the tanks and pipes need to be surface-treated to ensure that their surfaces are clean, free of oil and rust. During painting, it should be applied evenly; generally, multiple layers are required to enhance the anti-corrosion effect. It is recommended to conduct trials on a small scale first, observe the actual results, and then proceed with large-scale implementation. .
What do you think of the approximate binding force?
Glass flake coatings have strong adhesion and can adhere firmly to the surface being coated. To improve adhesion, it is necessary to ensure that the substrate surface is clean and dry, and to carry out appropriate surface treatment such as grinding or sandblasting, in order to increase surface roughness and enhance the coating’s grip. Proper surface pretreatment and coating procedures can significantly improve the overall performance and durability of the coating. .
