Resumo: Abstract Sapwood samples of Pinus pinaster wood were treated with a 70% furfuryl alcohol mixture. Weight percent gain (WPG), equilibrium moisture content, dimensional sta- bility, MOE, bending strength, hardness, density and dura- bility were determined. WPG was on average 38%. Equilibrium moisture con- tent decreased more than 40%. Dimensional stability in- creased reaching an ASE of 45%. MOE was little affected by the treatment but bending strength increased by about 6%. Hardness increased by about 50%, and density by 37%. Mass loss due to Postia placenta and Coniophora puteana decreased by 96% and 86%, respectively. Furfurylation of Pinus pinaster wood shows an interesting potential to im- prove the wood quality for solid timber products.

Die prozentuale Massezunahme lag im Durchschnitt bei 38%. Die Gleichgewichtsfeuchte nahm mehr als 40% ab. Die Dimensionsstabilität nahm zu und erreichte ein Quellresistenzvermögen (ASE) von 45%. Die Behandlung hatte nur wenig Einfluss auf den Elastizitätsmodul, während die Biegefestigkeit um 6% zunahm. Die Härte erhöhte sich um ca. 50% und die Dichte um 37%. Der Masseverlust durch Postia placenta und Coniophora puteana ging um 96% bzw. 86% zurück. Die Furfurylierung von Pinus pinaster Holz zeigt ein hohes Potential zur Verbesserung der Holzqualität von Massivholzprodukten.Repositório Científico do Instituto Politécnico de ViseuEsteves, BrunoNunes, LinaPereira, Helena2021-03-04T18:06:45Z20112021-03-04T15:50:15Z2011-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.19/6654engEsteves, B., Nunes, L. & Pereira, H.
