Evaluación de las propiedades físicas - químicas de Eucalyptus urograndis Eeucalipto), en el sector de Fumisa, cantón Buena Fe, provincia de Los Ríos

Abstract

The current research work proposed to evaluate the physical-chemical properties of Eucalyptus urograndis (Eucalyptus) of Fumisa, located in the Buena Fe County, Los Ríos Province through the georeferencing about the study area for the selection of plots considering the average and maximum diameters of each of the five provenances. The pieces of wood were obtained at the height of the DAP and commercial height. After that, it made samples of 3x4x7 (cm), obtaining eight test tubes for each tree of which, 4 were used for drying moisture content in the furnace that was made at a temperature of 103°C with intervals of 3 hours, giving a total of 6 measurements until the difference between measurements does not vary significantly. The measurements were made when the test tubes reached room temperature for 60 days. On the other hand, it determined the density in green, dried in the furnace, air dried and basic density. To determine the pH, it collected the wood sawdust which was mixed with distilled water and for its reading at the pH meter. In addition, it made a comparison between the density obtained by immersion and measured with digital measuring caliper obtaining results in provenance 2 for moisture content, density and pH. Key words: PHYSICAL-CHEMICAL PROPERTIES, WOOD MOISTURE CONTENT, WOOD TECHNOLOGY
