Hemlo Gold Mine

Mining
Associated Products:
Flexane® 80 Liquid

 
Problem:
This Urethane wear ring would receive extreme abrasive wear from processing a slurry of gold ore and water. The past repair method was to return to the manufacturer for re-surfacing. This repair procedure was costly and caused extensive downtime. Current repair method cost was $700 each unit.
 
Solution:
A wood model was built using a new ring as the mold. The metal ring was sandblasted to a SSPC-SP5 white metal finish. Repair surface was then chemically cleaned using Cleaner Blend 300. Both FL10 and FL20 Primers were applied and each allowed to cure or dry for 15 minutes. Using both primers will improve adhesion from 25 pli to 50 pli. A generous coating of Devcon's Release Agent was applied to the wood model. Release Agent must be applied for easy removal or separation of molded parts. Flexane 80 Liquid was injected into the mold forming a new urethane surface, bonding to the metal ring. Following full cure of Flexane 80 Liquid, (24 hours), the manufactured part was removed from the mold. Devcon's repair cost was $25 each unit.
