Influence of the increase density and resin level on mechanical properties of Chusquea culeou particleboard agglomerated with ureaformaldehyde

Abstract

The effect of increasing solid resin, and the density of manufactured Chusquea culeou Desv. particleboard, agglomerated with ureaformaldehyde was studied.
The one-layer boards were 11 mm thick, and were manufactured using shaves like those used in coke layers. The Densities studied were 450, 550, 650 and 750 Kg/m3 and the resin levels 6, 7, 8, 9 and 10% based on oven-dry shave weigth.
Mechanical properties were tested according to DIN standard, and were analized by linear regression. A high correlation between studied mechanical properties and density was found.
The adhesive effect was significant for the bending strength only over a 600 Kg/m3 density and with a resin level over 8%. Concerning internal bond, the increase resin level is advantageous in all studied densities.
