Abstract
Determination of wood colour modified with furfuryl alcohol. The aim of this study was determined the colour of wood (alder wood (Alnus glutinosa L.), poplar wood (Populus alba L.) and pine wood (Pinus silvestris L.)) by a colorimetric method after modification of furfuryl alcohol with maleic anhydride as a catalyst. The modification of wood was conducted out in two steps. In first step was treatment with a mixture of modifying wood, and then curing at 105 and 120°C. The value of the index WPG modified wood samples is influenced: wood species, composition of the modifying mixture and curing temperature treated wood. Use in the modification process furfuryl alcohol with maleic anhydride cause darkening of the wood surface and complete discoloration of the modified wood.
