Field Application Reports Products: Application Date: Customer: Industry: Location 35 Pump Repair Brushable Ceramic 3-15-99 Syncrude, Ft. McMurray Mining Problem: In mines, water feed pumps “wear” because of abrasive particles flowing through the volutes at tremendous speeds, causing wear and abrasion inside the volute and impeller areas. Pump casings are very expensive and instead of “replacing” the volutes, metal-filled epoxies are used to rebuild loose metal. These polymers act as better “wear resistant” finishes on the surface. In this pump, the volute areas had wear up to 1” deep, which had to be filled before a protective coating could be applied. Solution: The volute of the pump casing was sandblasted to an SSPC-SP5 white metal finish. After blasting, the pump was cleaned with our Cleaner Blend 300 to remove all residual abrasive shot from the surface. Then a primer coat of Brushable Ceramic (12-15 mils) was coated on all areas. Immediately after coating with Brushable Ceramic, the large voids (over 1” deep), were filled with Wear Guard High Load. The Brushable Ceramic acts as a primer helping the beaded epoxy adhere better to the surface. Next, Ceramic Repair was used to fill all other voids (under ½” deep). Finally, a topcoat of Brushable Ceramic (12- 15mils) was used for a smooth, final chemical resistant finish.
Field Application Reports Products: Application Date: Customer: Industry: Location 36 Pipe Repair Ceramic Repair Putty / Brushable Ceramic 3/30/93 Illinois Metro Water Reclamation Water Treatment Problem: This transition pipe would receive extreme cavitiation and abrasive wear from processing primary sewage water. The wear was so severe that the pipe required immediate replacement. Replacement part was no longer available. Solution: The repair area was sandblasted to a SSPC-SP5 white metal finish. Surface area was then chemically cleaned using Cleaner Blend 300. Ceramic Repair Putty was applied rebuilding the missing metal and cavitated areas deeper than 1/8”. Following a partial cure of Ceramic Repair Putty, (4 hours), Brushable Ceramic was applied to a thickness of 30 mils in two coats brushed at 15 mils each. Brushable Ceramic encapsulated repair areas and provided an abrasion resistant, low co-efficient to friction protective surface coating.
