Resumo: In this work, the effect of different compositions of virgin and recycled high density polyethylene/Pinus sp. on physical-mechanical properties of sheets made by compression molding was studied. The compositions were blended in a thermokinetic mixer (Draiss) and compression molded at 150oC. ASTM samples for tensile, flexural, impact and hardness tests were taken from the sheets. The density of the sheets were determined. The statistical model used was a centroid simplex with seven compositions and three repetitions. Results showed that tensile and flexural strength as well as hardness and density followed a linear model, while impact strength is explained by a quadratic model. Physical-mechanical properties of compositions using virgin and recycled HDPE did not show significative changes, except for impact strength, when virgin HDPE showed higher numerical results.

As misturas foram homogeneizadas em um misturador tipo Drais, sem controle de temperatura e moldadas por compressão em prensa hidráulica a 150oC. Partindo das placas, foram confeccionados corpos-de-prova para ensaios de tração, flexão, impacto e dureza, segundo normas ASTM, e também foram determinadas as densidades médias das placas. A modelagem estatística foi realizada segundo o planejamento centróide simplex, utilizando sete misturas dos três componentes e três repetições de cada mistura. Os resultados mostraram que a resistência à tração, a resistência à flexão, a dureza e a densidade das placas, são explicadas pelo modelo linear, enquanto a resistência ao impacto é explicada pelo modelo quadrático. Não houve diferença significativa nas propriedades físico-mecânicas dos compósitos confeccionados com HDPE virgem, daqueles confeccionados com HDPE reciclado, exceto para resistência ao impacto, no qual o HDPE virgem apresentou maiores valores.Universidade Federal de Santa Maria2006-09-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/191310.5902/198050981913Ciência Florestal; Vol. 16 No. 3 (2006); 343-351Ciência Florestal; v. 16 n. 3 (2006); 343-3511980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1913/1157Hillig, ÉvertonFreire, EstevãoCarvalho, Gláucio A.Schneider, Vania ElisabetePocai, Karlainfo:eu-repo/semantics/openAccess2017-05-15T13:37:29Zoai:ojs.pkp.sfu.ca:article/1913Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-05-15T13:37:29Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
