Physical-mechanical properties and heat transfer analysis of OSB produced with phenol-formaldehyde and ZnO nanoparticles addition

Oriented Strand Board is a structural wood composite with applications that require good physical and mechanical performance. The addition of ZnO nanoparticles an alternative has been studied in order to improve the properties panels. However, there no information about its effect Board. aim this work was evaluate influence zinc oxide two different percentages (0,25 % 0,50 %) on physical-mechanical panels produced phenol-formaldehyde resin heat transfer during hot-pressing. were tested according European Standards. improved dimensional stability panel, reducing thickness swelling, also increased screw withdraw strength. hot-pressing temperature more quickly boards addition; other hand final control treatment higher.
