After long-term use, adhesive coating equipment may experience peeling, rusting, and other phenomena. May occur. In this case, not only will the appearance of the equipment be affected, but the use of the tank will also be affected. So how to repair the surface of the lining rubber?
How to repair the surface of the lining rubber?
1. Surface treatment of the lining substrate. The comparison substrate before lining is sanded. Sandblasting can first effectively remove defects such as corrosion on the substrate surface. Sandblasting can also achieve good roughness on the substrate surface. Gain strong lining adhesion.
2. After cleaning and sandblasting with plasma and air compressor, evenly apply the adhesive to the surface of the substrate. Some experienced lining units ensure the quality of each layer of plasma coating. Compare different adhesives.
3. After the rubber is solidified and dried with a dry brush, place the plasma on the substrate and fully compact it with a pressure roller to ensure that there are no bubbles left.
4. After the intermediate inspection of rubber pasting is completed, carefully inspect it. The inspection items include: whether the adhesive sticker meets the requirements of the drawing, whether the edge distance is consistent with the flow direction of the medium, and whether the processing rod has bubble delay. Phenomena, try to eliminate defects before vulcanization.
5. In general, the equipment is vulcanized inside the kettle, and other reasons such as volume limitations cannot be vulcanized.
What is the introduction to the rubber lining repair plan?
As we all know, rubber lining is generally divided into two categories: hard rubber with rubber and synthetic rubber as the main body and soft rubber with rubber and synthetic rubber as the main body. Today we will talk about several lining methods.
What are the types of repair methods for lining vulcanization?
1. Heating method: Local repair is electric heating, suitable for hard and soft adhesives. Use it to deliver steam for local repair, suitable for hard and soft adhesives
2. Non heating method: repair with circular rubber plates, suitable for hard and soft rubber repair with glue, suitable for hard and soft rubber repair with thin rubber plates, mainly suitable for soft or hard rubber repair with self vulcanized rubber plates, mainly suitable for soft or hard rubber fixed with rubber strips, mainly suitable for rubber repair glue in soft rubber, mainly suitable for soft rubber.
3. Use electric heating for local repair, with the damaged area and the larger part of the damaged area as the center, tap with a grinding wheel or sand device, use vulcanized adhesive three times, paste the unvulcanized repair plate, roll it into shape with a roller, use electric heating to squeeze the fixture, and adjust it to the specified vulcanization temperature. After cooling, remove the fixture and use the wheel. Repair around the repair area.
