  • On the measurement of formaldehyde release from low-emission wood-based panels using the perforator method
    Wood Science and Technology, 2010
    Co-Authors: E. Roffael, B. Johnsson, B. Engström
    Abstract:

    In Europe, the perforator method (EN 120) is the mostly used laboratory method of the wood-based panel industry. Usually, the measured perforator value depends on the moisture content of the boards. According to DIBt-100, the measured perforator values are corrected to a common moisture content (MC) of 6.5% using an established equation proposed by Jann and Deppe ( 1990 ). The correction factor of Jann and Deppe ( 1990 ) is based on the assumption that particle- and Fibreboards change their perforator values to the same extent regardless whether increasing or decreasing the moisture content in the range of 3 ≤  u  ≤ 9%. Application of this correction factor to particle- and Fibreboards of higher moisture content than 6.5% can lead to biased corrected results in favour of low emission. The corrected values can also lead to paradoxical relation between the perforator values and emission in the low-emission region.

    Abstract:

    Abstract Urea-formaldehyde resin (UF) or phenolic resin (PF) is used widely as binder in the production of fiberboard, and formaldehyde emissions from UF or PF is seriously harmful for human health. Eco-friendly fiberboard was produced without binder using poplar wood shavings (PWS) bio-pretreated by white rot fungi Coriolus versicolor in this study, and the correlations between the metabolites and lignocellulose components and the bending strength (BS) of fiberboard were also studied. After PWS were pretreated by C. versicolor for 21 days, the BS and water swelling ratio of the fiberboard were reached to 22.7 MPa and 12.4%, respectively. The soluble polysaccharide and reduce sugar in PWS were detected very low, which had a weak effect on the fiberboard. Lower content of hemicellulose and higher content of lignin were detected and beneficial to the BS of fiberboard. Manganese peroxidase was detected and had a lag enzymolysis effect. Laccase, lignin peroxidase and cellulase were not detected but laccase or cellulase might have a weak influence on fiberboard. The fiberboard production with this bio-pretreatment should be eco-friendly and eliminate the potential formaldehyde emission.
