Resumo: | Agricultural residues are materials generated in large quantities in Brazil and can accumulate to such extent as to cause environmental problems. Among agricultural residues, maize cob is one worthy of notice, and an alternative use for maize cob would be to produce particleboard panels in association with wood particles. This study aimed to evaluate the feasibility of using maize cob for production of particleboard panels. The following maize cob percentages were used: 0%, 25%, 50%, 75% and 100%, in association with particles of Pinus oocarpa wood. Panels were made with 8% of urea formaldehyde and 1% of paraffin (based on dry weight of particles). For compressing the panels, a pressure of 3.92 MPa was applied at a temperature of 160º C, for 8 minutes. Increased replacement of pinewood by maize cob residue promoted significant improvements to the properties water absorption after two hours of immersion, thickness swelling after two and after twenty-four hours of immersion. Mechanical properties had a decreasing correlation with the maize cob percentage being incorporated. |

Um desses resíduos que merecem destaque é o sabugo de milho. Uma das alternativas para o reaproveitamento do sabugo seria a produção de painéis aglomerados em mistura com madeira. Objetivou-se, neste trabalho, avaliar a viabilidade da utilização do sabugo de milho para a produção de painéis aglomerados. As porcentagens de sabugo de milho utilizadas foram de 0%, 25%, 50%, 75% e 100% associadas com partículas de madeira de Pinus oocarpa. Os painéis foram produzidos com 8% de uréia-formaldeído e 1% de parafina (base massa seca de partículas). Na prensagem dos painéis, foi utilizada pressão de 3,92 MPa e temperatura de 160º C por um período de 8 minutos. O aumento da substituição da madeira de pinus pelo resíduo sabugo de milho promoveu melhoras significativas para as propriedades de absorção de água, após duas horas e inchamento em espessura, após duas e vinte e quatro horas. As propriedades mecânicas apresentam relação decrescente com a porcentagem de incorporação de sabugo de milho.Universidade Federal de Lavras2020-07-07T16:08:42Z2020-07-07T16:08:42Z2013info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfSCATOLINO, M.
