Field Application Reports Products: Application Date: Customer: Industry: Location 31 Conveyor Belt Repair Flexane® 80 Putty 5/15/93 Kennecott Copper Mining Problem: This 36” wide conveyor belt would receive extreme impact wear from processing ore. The previous method of repair was to have an outside contractor repair by vulcanizing. This method of repair was costly and frequently caused long unscheduled downtime. Solution: The complete repair area was roughened using a grinder and wire wheel attachment. Following roughening the area was chemically cleaned using Cleaner Blend 300. FL20 Primer was then applied and allowed to cure or dry for 15 minutes. FL20 Primer improves the chemical bonding properties of Flexane 80 Putty. Flexane 80 Putty was then mixed then applied replacing the missing worn rubber.
Field Application Reports Location 32 Pump Repair Products: Ceramic Repair / Wearguard Fine / Application Date: Brushable Ceramic Application Customer: Date: 7/14/93 Customer: Industry: Intermountain Power Services Industry: Utility Power Generation Problem: A high solids slurry combination of water and coal ash would cause severe abrasive wear to this bottom ash transfer pump housing. Previous method of repair was to simply replace the pump housing when required. Pump housing replacement cost was estimated to be $30K. Solution: Pump housing was sandblasted to a SSPC-SP5 white metal finish. Complete repair area was then chemically cleaned using Cleaner Blend 300. Ceramic Repair Putty was applied to rebuild wear ring seats, fill holes and repair eroded areas deeper than .125”. Ceramic Repair was allowed to partially cure for 4 hours. Wearguard Fine was applied to a thickness of between 1/2” and 1-1/2” depending on the depth of wear. Acetone was used to smooth and feather Wearguard Fine following gel point. Following a 4 hour partial cure of Wearguard Fine, Brushable Ceramic was applied to a thickness of 30 mils. Brushable Ceramic encapsulated the repaired areas, and provided a protective coating to the remaining exposed edges. Devcon’s repair cost was $1K.
