COMPORTAMIENTO AL SECADO NATURAL DE CUATRO ESPECIES MADERABLES DE BOSQUES SECUNDARIOS

Abstract

Con la finalidad de estudiar el comportamiento al secado natural de cuatro especies maderables de bosques secundarios, se efectuaron los ensayos pertinentes en las siguientes maderas: Trema micrantha (atadijo), Sapium marmieri Hubert (caucho masha), Jacaranda copaia Aube. D. Don (huamazamana) y Ochroma pyramidale Swartz (topa). Los ensayos se efectuaron de acuerdo a las especificaciones técnicas propuestas por Aróstegui et. al. (1975). Se ensayaron tablas de 2 x 15 x 120 cm, simplemente aserradas, rotuladas y con los extremos pintados con barniz sintético. Se apilaron horizontalmente sobre bases de madera a 35 cm del nivel del suelo y usando separadores de madera seca al aire y con un espesor de 2 cm.El contenido de humedad inicial se determinó en probetas de control por el método de secado en estufa hasta peso constante. En las tablas de ensayo se determinó la variación del contenido de humedad cada quince días mediante la variación del peso. Una vez que se tuvo un contenido de humedad por debajo del 20%, se procedió a evaluar defectos (grietas y rajaduras) y deformaciones (arqueadura, encorvadura, torcedura y revirado). Los resultados se interpretaron de acuerdo a las especificaciones propuestas por Aróstegui (1979). De acuerdo a los resultados se concluye que las cuatro maderas ensayadas en las dimensiones especificadas secan rápidamente al aire, la formación de defectos y deformaciones no es pronunciada.
