Method & Evidence

AimTo evaluate the physical-mechanical resistance of plywood panels bonded with nanotalc-modified phenol-formaldehyde adhesive compared to conventional synthetic adhesives.
MethodExperimental comparative study
ProcedurePhenol-formaldehyde adhesive was modified with varying concentrations of nanotalc (0%, 0.05%, 1%, 1.5%, and 2% by mass). Plywood panels were manufactured using Pinus oocarpa wood and these modified adhesives under controlled pressing conditions (8 minutes at 160°C and 1 MPa). Physical and mechanical characteristics of the panels, including water absorption and elastic modulus, were then determined and compared across the different treatments.
