Method for qualitative or quantitative determination of parameters of wood-based panels and method for controlling process variables

摘要

In the present invention, there is disclosed a method for qualitative or quantitative determination of parameters of a wood based panel produced from raw wood material flowing into a process for production of wood based panels, characterized in that the method comprises: - analyzing the raw wood material or the wood based panel while having a moisture content of below 10 percent by a spectrometric method giving spectral data, and - comparing said spectral data with reference spectral data obtained by said spectrometric method from reference raw wood material or reference wood based panels having a moisture content of below 10 percent, which reference spectral data have been calibrated to known parameters of wood based panels produced from said reference raw wood material or to known parameters of said reference wood based panel by means of multivariate analysis.
