1. The process of restoring the edge size: the first type of damage with larger edge damage size is repaired by the method of restoring the edge size. The purpose is to restore the effective use area of the conveyor belt and prevent further expansion of the edge of the conveyor belt. See Figure 3 for construction schematic. Construction points: The L-shaped polyurethane repair strip with a thickness of 18 mm and a width of 10 mm, or a square-shaped polyurethane repair strip with a thickness of 15 mm and a width of 30 mm is firmly bonded to both sides and the lower side of the edge of the conveyor belt, with flow The filling performance polyurethane V218 conveyor belt repair glue will fill the irregular conveyor belt edges evenly and make it a firm and flexible whole. The advantage of the solution is to convert the edges of the upper, middle and lower three-layer structure into an edge of integrated thickness. The second is to convert the rubber edges with low wear resistance and impact resistance into those with excellent wear resistance and impact resistance. Polyurethane edges.
2. Wrapping edge process: For the second type of damage with a smaller size of the edge damage, use the method of wrapping the edge to repair. The purpose is to prevent further expansion of edge damage. The construction diagram is shown in Figure 4. Construction key points: wrap a strip of polyurethane repair strip with a thickness of 2.5 mm and a width of 10 mm on the damaged edge. Its advantages are: make the upper and lower rubber and core rubber of the edge part form a complete whole, obtain a tough protective layer, effectively resist the edge impact and damage; obviously improve the wear condition of the lower side, and the weakest edge of the conveyor belt Place a layer of the most wear-resistant material to protect the conveyor belt.
