COMPORTAMENTO DE LIGAÇÕES ADESIVAS EM MADEIRAS DE REFLORESTAMENTO

Abstract

RESUMO Madeiras de pinus e eucalipto foram coladas variando a quantidade de adesivo, pressão de colagem e diluição do resorcinol. As resistências das juntas coladas e da madeira sólida foram determinadas, juntamente com a percentagem de falhas e massa especifica. Na madeira de pinus, os melhores resultados de resistência foram obtidos para taxa de aplicação de 600 g/m2 e pressão de colagem de 1,0 MPa. Estatisticamente, as diluições em até 10% e 15%, respectivamente, para pinus e eucalipto, tiveram o mesmo desempenho do adesivo não diluído. Na taxa de aplicação de 600 g/m2, a resistência média das juntas coladas de pinus ultrapassou a resistência da madeira sólida, e as de eucalipto também , nas diluições até 15% na pressão de 1,0 MPa. A quantidade de 300 g/m2 pode ser considerada aceitável em ambas madeiras, pois as resistências das juntas coladas atingiram as resistências das madeiras sólidas.
