What should be done with rebound material during gunning operations?

During gunning operations, rebound material, which consists of refractory material that bounces off the surface instead of adhering to it, should typically be disposed of immediately. This is because rebound material may not maintain its integrity or performance characteristics after being dislodged, and using it could compromise the quality and reliability of the installation. Gunning operations require precise material application to achieve the desired thickness and surface properties. Using rebound material could introduce inconsistencies and defects, potentially leading to failure during service conditions.

Disposing of the rebound material ensures that only fresh, uncontaminated refractory material is applied, promoting better bonding and maximizing the effectiveness of the installation process.
