Inflatable rubber fender is widely used because of its excellent waterproof performance, why does inflatable rubber fender have poor waterproof effect? How to solve it?

1. Material aging: Due to price competition, many manufacturers cut corners, which will reduce the performance of the polyurethane material itself, resulting in waterproof failure. Solution: To purchase polyurethane materials, you must select a certified manufacturer and confirm the relevant certificate and production date.

2. The base material contains water: polyurethane, a material used to make inflatable rubber fenders, contains both water and oil. Check whether the base is dry before construction. If it is an oily material, water will be wrapped in it, and the waterproof layer may peel off after the sunlight is converted to steam. Solution: First determine whether it is oil-based polyurethane or water-based polyurethane. If it is oil-based polyurethane, ensure that the base surface is dry before construction.

3. The bottom layer is not cleaned: Before waterproof construction, the bottom layer should be cleaned. If there are substances such as dust, the adhesion between the waterproof layer and the bottom layer will be weak, which will lead to the risk of leakage. Solution: During construction, the bottom layer should be clean and smooth, without floating ash and oil.

4, the waterproof layer is too thin: the waterproof layer must reach a certain thickness to be effective. Because the polyurethane material itself has low water absorption, if the waterproof layer is not thick enough, the water will reach the bottom through the polyurethane waterproof layer. When the sun hits, water vapor is created at the bottom, and then the waterproof layer is peeled off. Solution: To ensure the thickness and frequency of the coating, the four corners of the fiber mesh for strengthening treatment.

5. Less than construction experience: waterproofing works should be carried out by professional construction teams. Before construction, the possible causes of leakage should be carefully predicted. Solution: Must entrust professional construction team, construction quality will directly affect the final effect.
