Encapsulated Active Ingredients for Wood Preservation
2017 - IRG/WP 17-30717
Encapsulated organic fungicides and termiticides have been examined for use as wood preservatives in vacuum pressure treatment of wood. Encapsulation of active ingredients was found to improve wood penetration behaviour and reduces leaching as well as biodegradation of the active ingredients compared to industrial standard formulations....

Water analysis in chemicals, wood or chemically treated wood using a new analytical method for selective water detection
2006 - IRG/WP 03-30391
Water or moisture content analysis can be a challenging task in many applications. However, knowing accurately the type of water which can be found in a given sample or product can provide important information about a chemical compound used for wood treatment and especially about the treated wood sample.
Moisture content in wood plays an important role in fungal growth and it needs to be extensi...

The effect of brighteners on wood surface aesthetics – exploring the use of various organo-phosphonates based precursors
2007 - IRG/WP 07-30441
Freshly cut hardwood lumber such as white oak, red oak, beech, or redwood are rich in mineral stain (mostly iron and calcium), which provides a strong discoloration of the wood surface significantly influencing the aesthetic of the wood surface and strongly affecting the cost of this lumber. The influence of mineral stain on soft wood discoloration (Southern Yellow Pine, Douglas fir, etc.) is les...

The amazing wooden churches from Northern Romania - learning from the past, restoring for the future, preserving the present valuable heritage of forgotten wood building tradition
2009 - IRG/WP 09-10683
The beauty and the uniqueness of the north-western region of Romania called “Maramureş” are well known in Europe. Surrounded by mountains, the region remained to some extend isolated from modern influences, preserving the local village architecture and craftsman traditions learnt and passed on from generation to generation. Local folklore and past heritage sets you back centuries ago when...

A theoretical-industrial correlation and perspective on copper-based wood preservatives - a review of thermodynamic and kinetic aspects on copper-wood fixation mechanism
2009 - IRG/WP 09-30499
Copper was and it will continue to remain one of the key active component in wood protection industry. Over the past decades, a significant effort from R&D teams in industry, academia and research institutes was directed toward understanding the copper-wood fixation mechanism, optimising the copper retentions in the wood and reduce leaching in order to maximized performance, prolong the lifetime o...

A comparative study and evaluation of methodologies used for determining wood preservative penetration
2011 - IRG/WP 11-20475
A series of methods for determining penetration of wood preservatives into the wood structure have been developed for either quality control (QC) or research and development purposes. QC methods range from monitoring the solution uptake, applying colour indicators or sampling specific wood samples followed by wood acid digestion/atomic absorption spectroscopy (AAS) or solvent extraction/chromatogr...
