(2012): Within-process and seasonal changes during industrial production of high-density fibreboard. Part 2: PLS modelling of chemical alterations, refining conditions and panel thickness swell

Abstract:
Wood species, carbohydrate composition and the content of extractives were determined from extracted wood chips and refiner fibres over 1 year of sampling at an industrial high-density fibreboard (HDF) plant. Correlations were found among processing variables (discharge screw flow, digester and refiner pressure, and refiner power consumption) and the analysed composition of raw materials and semi-finished product based on partial least squares regression (PLSR) analysis. Moreover, correlations between the degree of hemicellulose degradation and process variables were found. Panel thickness swell (PTS) was found to be affected by several raw and fibre material characteristics (based on PLSR), in which PTS was lower in the case of good fibre quality. These results demonstrate the potential impact of variable raw material properties on product properties and processing conditions in an industrial environment.
