Mechanical properties and resistance to fungi and termite in particleboard of eucalyptus
The objective of this study was to evaluate the mechanical resistance and resistance to degrading agents in particleboard with eucalyptus wood residue and Urea-Formaldehyde, Phenol-Formaldehyde and Tannin-Formaldehyde adhesives at two temperatures (120 ºC and 140 ºC).

| description | The objective of this study was to evaluate the mechanical resistance and resistance to degrading agents in particleboard with eucalyptus wood residue and Urea-Formaldehyde, Phenol-Formaldehyde and Tannin-Formaldehyde adhesives at two temperatures (120 ºC and 140 ºC). The panels were produced in the dimensions of 40 cm × 40 cm × 1.25 cm (width, length and thickness, respectively); 10% and 20% of tannin (50% solution) was added to the pure adhesives. The following parameters were evaluated: Modulus of Rupture (MOR) and Modulus of Elasticity (MOE) in static bending, internal bonding, screw withdrawal, resistance to rotting fungi and dry wood termite. MOR showed better results at 120 °C. None of the treatments reached the minimum standard for the MOE, contrary to the internal bonding. The Trametes versicolor fungus caused greater mass loss to the tested panels when compared to Postia placenta. The proportion of tannin (90:10) in the phenolic adhesive contributed to a decrease in the resistance of the panel to the dry wood termite. |

El objetivo de este estudio fue evaluar la resistencia mecánica y la resistencia a agentes degradadores en tableros de partículas con madera de eucalipto con adhesivos a base de urea-formaldehído, phenol-formaldehído y tanino-formaldehído a dos temperaturas (120 °C y 140 °C). Las dimensiones de los tableros fueron 40 cm × 40 cm × 1.25 cm (ancho, largo y grosor, respectivamente); se agregó 10% y 20% de taninos (solución al 50%) a los adhesivos puros. Los parámetros evaluados fueron: módulo de ruptura (MOR), módulo de elasticidad en flexión estática (MOE), cohesión interna, extracción de clavos, resistencia a descomposición por hongos y a termitas de madera seca. El hongo Trametes versicolor causó mayor pérdida de masa a los tableros ensayados en comparación con la causada por Postia placenta. La proporción de taninos (90:10) en el adhesivo fenólico contribuyó a disminuir la resistencia del tablero al ataque de termitas de madera seca.
