Abstract
When used in industrial processes, such as stirred acid leaching in the mineral industry, thermoset coatings are exposed to a combination of aggressive chemicals and erosive particlewear. While each exposure condition has been studied separately, no research has been presented on the effects of a simultaneous exposure. To investigate this, a pilot-scale stirred acid leaching tank, containing erosive particles and acidic solutions, has been designed and constructed. Resin types considered are amine-cured novolac epoxy and vinyl ester. Transient coating degradation is mapped through visual inspection and changes in film thickness.The new set-up, capable of experimenting with erosive particles in acidic solutions, is presented. In addition, results from preliminary experiments, using abrasive particles and water in a high-speed disperser, are discussed.
