Influence of the addition of Al2O3 nanoparticles and the duration of pressing on the physical properties of OSB panels

For greater durability, materials must withstand contact with water, making it difficult for biodegrading agents to attack. The present study produced and evaluated the heat transfer two pressing times physical properties of OSB panels, pinewood strands Al2O3 nanoparticles addition. were synthesized through sol-gel-protein method added resin in proportion 0.5%. During process, distribution central region particle mat using a type K thermocouple. After its fabrication, panels characterized evaluate density, moisture content, thickness swelling, water absorption. results obtained indicated that nanoparticle addition caused refractory effect mat, leading small reduction temperature 600 s cycle. However, there was no compromise cure, indicating good interaction contact, both times. There an improvement panel swelling 0.5% nanoparticles, all meeting Class 1 indicators EN 300 (2006) standard.
