Avaliação e Caracterização de Tubos Fabricados com PVC Reciclado

Abstract: Resumo: Neste trabalho foram caracterizados dois polímeros utilizados na fabricação de tubos de PVC, tendo como diferencial o uso de resina de policloreto de vinila virgem e reciclada. O uso da resina reciclada, derivada do reprocessamento de resíduos aterrados (sanitários ou industriais), foi avaliado com o objetivo de compará-la a produtos fabricados com resina virgem, os quais foram submetidos aos ensaios de Fluorescência de Raios X (FRX), Difração de Raios X (DRX) e resistência à tração e alongamento. Os r… Show more

“…It is also observed, for both samples, the presence of the peak at 3425 cm −1 , assigned to the presence of O-H hydroxyl groups, in the structure. Although unexpected, the presence of this band for PVC may be related to additives added during the synthesis of the polymer [ 18 ]. For the PVCDS, the increase in the intensity of this band is related to the chemical modifications undergone during the process of dehydrochlorination and subsequent treatment with sulfuric acid.…”
