Resumo
Polymeric materials, such as polyurethanes and rubbers, are widely used in the mining industry because of their moderate cost and excellent mechanical properties. Such polymers have been used mainly in transportation (conveyor belt systems and pipes coatings) and screening, for their appreciable abrasion wear resistance. Studies revealed the complex influence of test parameters, such as grit size and applied normal load, on the abrasion wear process for polymers. In this study, the abrasive wear behavior of several polyurethanes and rubbers were investigated at room temperature according to a rotary drum abrasion method (DIN 53516). Wear tests were carried out at 26 cm/s test speed and load value of 5 N and 10 N. Corundum paper grit varying from 60 to 400 mesh were used as an abrasive surface. After each test the mass loss of the pin was recorded and the wear rates were calculated from wear volume. The wear surfaces were investigated by scanning electron microscopy.
