DURABILIDAD NATURAL E INDUCIDA EN TABLEROS DE PARTICULAS DE PINO CARIBE CON UREA FORMALDEHÍDO

The efficiency of a hidrosoluble preservative (CCA-C salts) for prevent the xylophages fungus attack in particleboard caribean pine was studied. Homogeneous board were manufactured with variable preservative using the formaldehyde urea adhesive. The physical and mechanical properties of the boards of density 0,600 g/cm 3 demonstrated that the application of preservative influence significantly in the characteristics of the boards. The physical and mechanical properties of the boards of density 0,800 g/cm 3 demonstrated that the application of preservative doesn’t influence significantly in the characteristics of the boards. The natural and induce CCA durability of the particleboard was determined by using soil block test E10-91 (ASTM D-1413) utilizing a brown-rot fungus, Gloephyllum trabeum, and a white-rot fungus, Trametes versicolor. An incubation period of three months was used and the durability was determined by the percentage of weight loss in the period. Gloephyllum trabeum produced the greatest weight loss on the untreated 0,600 g/cm 3
