Brown-rot decay of copper-impregnated wood

International Biodeterioration & Biodegradation, 2006
Abstract Copper-based preservatives will be the predominant solution for wood protection in future decades. The composition of those preservatives will likely change from copper–chromium to copper–ethanolamine, due to environmental demands. The most important drawback of copper-impregnated wood is the presence of tolerant fungal organisms that have ...

Modeling of Alkali Impregnation of Eucalyptus Wood

Industrial & Engineering Chemistry Research, 2011
In wood pulping processes, the quality of the impregnation stage has a significant influence on the final pulp properties. In this work, a refined version of a previously published model is used to analyze this operation stage. For liquor containing NaOH and Na 2 S, the study considers the reaction of wood acetyls and acidic groups.

Wood impregnation

2016
Wood impregnation is one of the oldest and the most frequently used techniques to protect the wood. This treatment offers a wide range of protection depending on used impregnants (preservatives). Impregnation can make the wood more resistant to decay, less flammable, more dimensionally stable, harder, stronger, more UV stable resistant and many more ...

RESEARCH OF THRU IMPREGNATION OF LARCH WOOD

Proceedings of the International Forest Forum, youth section "Adaptation of forestry to climate change: nature-oriented solutions and digitalization. Forestry – 2024»
Larch wood is available as a resource, so it is important to solve the problem of its cracking. The proposed modification method to prevent cracking of wooden larch by pre-welding and preparing impregnation from the end under pressure with 30% aqueous solution of urea.

Hygroscopicity of wood impregnated with linseed oil

Wood Science and Technology, 1980
The reduction in hygroscopicity as spruce wood is impregnated with linseed oil may be accounted for using a molecular exclusion model. On the basis of the model, each linseed oil molecule appears to displace 90 water molecules and occupy 6 hydrogen bonding sites in the wood.
