How about the belt repair patch? Proper operation is crucial!

When issues such as scratches, damages, or tears occur during belt operation, repair strips are typically used for remediation. After applying the repair strips, the damaged areas no longer expand, effectively ensuring the overall performance of the belt post-repair.
The use of repair strips significantly reduces the difficulty of belt repairs, making the process simpler and faster. This is also one of the reasons why many mining and construction workers choose repair strips.
The characteristics of the repair tape itself and on-site operations are crucial factors in ensuring the bonding effectiveness of the repair tape. When selecting repair tape, construction personnel must adhere to on-site requirements to choose the appropriate type and strictly follow the operational procedures for on-site application.
Currently, the repair strips widely used by major mining and industrial enterprises are mostly belt repair strips with a CN layer, among which the most commonly employed are the imported belt repair strips from Inmet.
The surface of the Inmet imported belt repair patch is made of wear-resistant rubber, ensuring anti-slip and wear-resistant properties for the belt. The bonding surface features a blue CN semi-vulcanized layer, which reacts with the cold vulcanization adhesive after application, allowing the two to fuse seamlessly. This ensures strong adhesion between the repair patch and the belt, with bonding strength exceeding three times that of ordinary repair patches.
Use a high-power, low-speed angle grinder equipped with a tungsten carbide grinding disc of appropriate grit to perform intermittent grinding on the damaged belt section;
Clean and sand the surface, then apply a cleaning agent to deeply remove oil stains from the belt;
Apply cold vulcanization adhesive to the damaged belt section, let it dry, then apply another coat. Additionally, apply a coat of adhesive to the bonding surface of the repair patch;
Attach the repair patch to the damaged area, then use a compaction roller to press it firmly and expel excess air.
Precautions for Repair Tape Operation
Grinding thickness
To prevent the cleaner from scraping off the repair patch, the worn section of the belt should be ground to a thickness no less than that of the repair patch. If the repair patch is 2.2mm thick, the grinding thickness must be ≥2.2mm.
Painting Requirements
When applying glue to the repair strip, it must be brushed onto the blue CN layer. Some workers, due to negligence, apply the glue to the black rubber surface, which significantly reduces the effectiveness of the repair strip adhesion. Extra caution is essential.
