Field Application Reports Products: Application Date: Customer: Industry: Location 25 Rubber Lined Flange Connector Repair Fasmetal / Flexane® 80 Putty 4/9/93 Kennecott Copper Mining Problem: This rubber lined flange connector from the floatation cell received extreme wear from a slurry combination of mineral, ore and floatation chemical solution. Previous method of repair was to simply replace the connectors, however a replacement part was not available. Solution: Inside bore area and outside sleeve were roughened using a grinder and wire wheel attachment. Complete repair areas were chemically cleaned using Cleaner Blend 300. Fasmetal was applied to the outside area to replace missing metal and plug holes. FL10 and FL20 Primers were applied and each allowed to cure or dry for 15 minutes. Using both primers will improve adhesion of Flexane 80 Putty from 25 pli to pli. Flexane 80 Putty was applied to the bore area replacing the worn rubber.
Field Application Reports Products: Application Date: Customer: Industry: Location 26 Rod Mill Repair Fast Cure Rubber Repair Putty 3/03/00 Tampa Electric Co. / Polk Power Station Power Problem: Wear plates inside the coal grinding rod mill become worn and sloppy. These open joints cause coal to “hang up” in these areas and loosen the wear plates. This will use efficiency problems in the grinding of the coal Solution: First all the wear plates joints were blasted to a SSPC-SP5 finish. Then the joints were cleaned with a water base degreaser and allowed to dry. Next our Flexane FC Putty was applied using he 400 ml cartridge delivery system using the pneumatic gun. The material was injected into the joints between the wear plates and a mechanic than “smoothed out” the material to bridge the plates. Material was allowed to dry for 24 hours and then put back into service!
