The vinyl glass flake resin lining in the desulfurization tower began to peel off after 2 years of use; how can it be repaired?

For the repair of a detached vinyl glass flake resin lining, the following steps are recommended: 1. Clean the detached area: First, it is necessary to completely remove the detached resin and any loose material. Use a high-pressure water gun or appropriate mechanical equipment to clean the affected area, ensuring that there are no debris or dust left. 2. Surface treatment: The exposed metal surface is polished or sandblasted to increase its roughness, which helps improve the adhesion of the new coating to the substrate. 3. Primer application: Apply a suitable layer of primer to enhance the adhesion of the resin and ensure optimal repair results. 4. Apply resin topcoat: Use a vinyl glass flake resin of the same type or compatible with the original one; after mixing it in the recommended proportions, apply it evenly to the treated area. Multiple applications may be required to achieve the original thickness. 5. Curing and inspection: Cure the resin for the duration specified in its instructions, then conduct a thorough inspection to ensure that there are no significant height differences between the repaired area and the surrounding old coating, and that the repair is firmly attached. 6. Regular monitoring: After the repair is completed, the desulfurization tower should be inspected regularly to monitor the condition of the lining, and maintenance records should be kept. If new abnormalities are detected, they should be addressed promptly. To ensure compliance with safety standards during the operation, it may be necessary to have professionals carry out the aforementioned tasks. .
