Abstract

Today there is exponential growth in the use of wood from the Eucalyptus genus in the wood industries. Given its importance in the forestry and wood marketing industry, there is a clear need to implement technologies that provide better quality wood and improved drying processes. Because of this, the objective of this study is to evaluate two methods of drying Eucalyptus grandis wood after impregnation with silver nanoparticles. To this end, logs of this species were used, which after making the test specimens and impregnation with silver nanoparticles of 40 and 100 ppm, they were subjected to drying in a climate-controlled chamber, with an average temperature of 20°C and relative humidity of 65%, and a laboratory oven with forced circulation at a constant temperature of 60°C, for subsequent moisture content analyses, drying rate and defects. The results showed that there was a greater loss of moisture in those pieces with an impregnation of 40 ppm when drying in an oven and air-conditioned chamber, as well as a higher drying rate in an oven. Furthermore, there was a higher incidence of defects in wood impregnated with 100 ppm and dried in an oven, with those impregnated with 40 ppm and dried in the same method presenting lower values than the control. The specific mass obtained average values similar to those referenced in the literature for the species worked. From the results of the present study, it was possible to conclude that the impregnation of silver nanoparticles brings drying benefits to Eucalyptus grandis wood.
