Determinación de las propiedades de higroexpansión de tableros compuestos a base de madera

Abstract

Los tableros de madera se expanden cuando están expuestos a la humedad en condiciones de servicio. En consecuencia, su funcionamiento como material de ingeniería empobrece y ocasiona costos de reparación y/o remplazo. El objetivo de la investigación fue determinar las densidades y las higroexpansiones de tableros contrachapados, enlistonados, de densidad media y de astillas orientadas de madera. Se evaluaron los mismos parámetros en un grupo de control de madera sólida de Pinus pseudostrobus. De cada material se prepararon 35 probetas seleccionadas al azar. Se realizaron pruebas de higroscopía con un protocolo de humidificación y secado del material experimental. Las higroexpansiónes de los tableros contrachapados, enlistonados, de densidad media y de astillas orientadas son diferentes en comparación con la higroexpansión de la madera sólida de P. pseudostrobus. La madera y los tableros de madera presentan un carácter higroscópico, el cual resulta en una variación dimensional si su contenido de humedad se modifica. Las magnitudes de las higroexpansiones de los cuatro tableros estudiados son mayores a la correspondiente a la madera sólida de P. pseudostrobus.
