Correlação entre abrasão e alongamento de borracha composta de SBR utilizado em correias transportadoras

Abstract

This course conclusion work aims to study and analyze correlations between the physical parameters of the rubber compound W, widely used in the production of upper and lower coverage of conveyor belts. The aim is to find a correlation between abrasion and elongation, due to the fact that abrasive wear is a field challenge faced by belts. Furthermore, establishing a relationship between abrasion and some other parameter will facilitate the prevention and diagnosis of possible losses that may occur. The exploratory research carried out mechanical tests on rubber samples used for the production of belts and, from the results, verified a correlation between abrasion and elongation. The test results allowed us to conclude that the aging led to the loss of mechanical properties of the rubber samples, being possible to conclude only that both properties (abrasion and elongation) result with time and temperature. In order to determine a score between them and show that they are inversely proportional, you need a large amount of samples and a longer time in the aging test.
