Painéis de madeira aglomerada de Eucalyptus badjensis e Pinus spp.

The objective of this study was to determine the physical properties of Eucalyptus badjensis panels to assess potential use of the species as an alternative raw material for the production of chipboard panels. Three treatments were used, made up of 100% Eucalyptus badjensis; 50% Eucalyptus badjensis and 50% Pinus spp .; and 100% Pinus spp. For each treatment were made four repetitions, totaling 12 panels. The panels were produced with nominal density of 0.65 g.cm-3 and the pressing cycle temperature to 180 ° C, pressure of 40 kgf and 8 minutes press time. The following properties were evaluated: Apparent density, compression ratio, water absorption in 2 to 24 hours (AA2h and AA24h) Swelling in thickness in 2 to 24 hours (IE2h and IE24h) in thickness and not return rate. From the results it can be concluded that considering the physical properties, the panels produced with the Eucalyptus badjensis showed good results and the species may be considered as a potential source of alternative raw material for the production of chipboard panels.
