|metadata.revistascielo.dc.description:||This work aimed to evaluate the quality of strand particles gluing and its influence on the final bonding quality in OSB panels. The measurement of the dimensions and determination of the mass of 658 particles were made before and after the gluing process. The variables glue amount (g.m-²) and effective amount of adhesive applied (%) were evaluated. Phenol-formaldehyde adhesive was applied at 6, 9 and 12% contents in Pinus oocarpa and Eucalyptus grandis particles. Perpendicular tension strength test was conducted in the panels produced. The gluing process in laboratorial conditions is heterogeneous, which hinders the analysis of the influence of the processing variables on the effective amount of adhesive applied and glue amount. It was verified that OSB panels made from Pinus oocarpa species presented lower glue amount per particle in relation to Eucalyptus grandis species. This result was attributed to the lower basic density of Pinus oocarpa wood. Increases in glue amount of particles are related to increases in perpendicular tension strength.|
