dc.description.abstractEngineered wood products (EWP) manufacturing involves stages like the preparation of raw materials, adhesive application, pressing, and finishing. Each stage of the manufacturing process presents specific quality control challenges that must be addressed. The development of rapid non-destructive analytical techniques is critical for improving quality control in EWP manufacturing. This study investigated the implementation of near-Infrared (NIR) technology for monitoring phenol-formaldehyde (PF) and polymeric methylene diphenyl diisocyanate (pMDI) adhesive contents in wood strands during the production of Oriented Strand Board (OSB). The study involved diverse sampling methods and the construction of principal component regression models relating NIR spectra to adhesive loading. Both devices yielded reliable predictive models(R2 >70%) indicating that both devices can achieve high predictive accuracy, with the portable being particularly suited for on-line applications. This study demonstrated the feasibility of NIR as a tool for adhesive monitoring in OSB manufacturing highlighting the potential to enhance production efficiency.en_US
