Problem:<br />
Lower vortex area of this recovery cyclone would receive extreme wear to the rubber lining from the<br />
abrasion of processing steel grit blast material. Previous repair method was to replace rubber lining or<br />
weld patches <strong>and</strong> plugs to the exterior of the cyclone body. Welding had previously caused rubber<br />
distortion problems.<br />
Solution:<br />
The repair area <strong>and</strong> existing rubber liner were roughened using a grinder <strong>and</strong> wire wheel. Complete<br />
repair area of the cyclone was chemically cleaned using Cleaner Blend 300. FL10 Primer was applied to<br />
all exposed metal surfaces <strong>and</strong> allowed to dry for 15 minutes. FL20 Primer was applied over the FL10<br />
primed metal as well as all rubber contact surfaces. FL20 Primer was allowed to dry for 15 minutes.<br />
Flexane 80 Putty was applied to a thickness of .500” replacing the worn rubber. Following a partial cure<br />
of Flexane 80 Putty, (4 hours), Flexane High Performance Brushable was applied to blend the urethane<br />
<strong>and</strong> rubber, <strong>and</strong> provide a smooth, impact <strong>and</strong> abrasion resistant protective coating.
