摘要: The quantitative penetration of three coldset wood adhesives [one-component polyurethane (PU), emulsion polymer isocyanate (EPI), poly (vinyl acetate) (PVAc)] under hydraulic pressure into different types modified was studied using fluorescence microscopy and the results were compared to these a previous study without on adjacent samples. effective (EP) PU negatively affected by furfurlylation NMM modification when applied. For PVAc, 30% treatment heat Scots pine beech at 210 °C had negative effect its EP, but against this EP adhesive increased after 195 °C. In case furfurylation, depth all less treated with higher concentration furfuryl alcohol. showed much deeper NMM-modified heat-treated than other exception Application led rather as data no three-dimensional (3D) visualisation also examined X-ray micro-computed tomography (XµCT). 3D flow pattern clearly depicted XµCT.
