Durabilidad natural de tableros aglomerados de cocotero

Abstract

La industria de fabricación de tableros aglomerados (TA) emplea, tradicionalmente, descartes de madera de pino como materia prima y, en ocasiones, bagazo de caña. Se han realizado trabajos para incorporar otras materias primas no convencionales, cuidando que las propiedades físico-mecánicas no desmerezcan respecto a las habituales. La resistencia al biodeterioro a través del tiempo es una cualidad que no ha sido investigada. El objetivo de este trabajo fue estudiar la durabilidad de los TA de estopa de coco (TAEC) y de fuste de palma de coco (TAFPC) frente al ataque de hongos xilófagos. Se empleó la norma ASTM D-2017-71 para durabilidad de madera, que se basa en la pérdida de peso y cambio de dimensiones de los bloques de prueba (2.5 x 2.5 cm) ante el ataque de hongos, en incubadora (65-70 % de humedad relativa, 26-27 °C), por un periodo de hasta 16 semanas; se hizo una modificación a dicha norma que consistió en cambiar el método de propagación de los hongos de bloque-suelo por un medio de cultivo: agar malta dextrosa (MEA) y agar papa dextrosa (PDA). Como referencia se empleó un TA de pino comercial (TAP). Los hongos de degradación fueron tres de pudrición parda y uno de pudrición blanca (Laetiporus sulphureus, Neolentinus suffrutescens, Postia placenta y Phanerochaete chrysosporium respectivamente). Los datos obtenidos indican que los TAEC y TAFPC resultaron altamente resistentes a los cuatro hongos, lo cual es atribuible a las características propias de los materiales de prueba.
