RUBBER CONVEYOR BELTS WORN-OUT & THROUGH-HOLE REPAIRS

Surface Preparation:

1. For thin rubber thickness (3mm or less), the damaged zone must be roughen with an power tool wire brush at low rotation speed (750rpm to 900rpm) on and around the damaged zone. For thicker rubber thickness greater than 3mm, a 45° bevel must be cut around the edges of the damage area so as to create a trapezium shape around the damaged area. Roughen with an power tool wire brush at low rotation speed (750rpm to 900rpm) on and around the damaged zone. In the event of passing rips or damage, perform the same procedure including also the lower surface.
2. Before applying the repair putty, ensure that the application surface is always be dry, clean, and free of impurities. Clean the surface thoroughly with an abrasive pad and solvent-based contact cleaner & degreaser. If the chosen area is wet, it must be dried with a hot air gun. If humidity is high, the scraping process will suffice to remove the first layer of rubber that is wet.
3. For though hole rubber conveyor belt repair, adhere a layer of non-stick PVC film or several layers of masking tape on the bottom side of conveyor belt, to prevent mixture from running off of repair putty. Secure the PVC film or masking tape with staples in the lower part of the damage.
