Where do we start to repair damaged membrane structures? What are the ways to check the damage of membrane structure? How long does it take to repair the damaged membrane structure? Today, I will take everyone to find out!
1. If only part of the surface coating of the membrane material is worn and the fibers of the base fabric are intact, you can use high-performance transparent glue to stick to the problem area;
2. If the planned length of the membrane surface damage is less than 50mm, you can choose to cut out an oval or circular membrane cloth, and weld the layers on the corresponding area;
3. If the planned length of the membrane surface damage exceeds 50mm but is less than 300mm, consider preparing a membrane strip whose length and width are both 150mm larger than the damage plan, and layer welding on the membrane surface of the corresponding area;
4. If the damaged part of the membrane surface exceeds 300mm, it may be necessary to consider whether to remove the entire unit and return it to the factory to repair or replace the entire unit.
According to the different specific correction methods of the membrane material, there are the following types:
1. The film material covered by the PVC coating can be repaired with a hot air blower
2. Clean up the area to be supplemented and lay it flat, and use hot air to melt the PVC coating on the surface of the membrane so that they can be joined together robustly.
3. For the membrane material covered by PTFE coating, it is necessary to add a layer of fluorinated ethylene propylene film between the patch and the original damaged membrane material, and then press it on the patch with special hand-held welding equipment.
4. Use high temperature to melt the fluorinated ethylene propylene film to weld the patch on the film surface.
5. Pay attention to the heating temperature and heating time during the specific operation, so that the surface coating of the film or the FEP film should be fully melted, so that it can stick together robustly.
