A process for spectroscopic measurement of the emission of formaldehyde from refined wood products destined to be used in the manufacture of composite wood products such as medium density fiberboard (MDF), particleboard, and plywood. The process employs near-infrared (NIR) spectroscopy to measure the absorption of light by the wood furnish; the level of absorption is then related to the formaldehyde emission and thickness swell of the finished wood panel. This process allows for real-time quantitative prediction of future formaldehyde emissions and thickness swell of a composite wood panel. |
