Expert versus multi-sensor evaluation of wood samples after short term weathering
2016 - IRG/WP 16-20587
Understanding the influence of weathering factors and the material degradation mechanisms are fundamental for modelling the weathering process of wood. The goal of this work was to investigate the combined effect of time and exposure on the physical-chemical mechanisms of wood weathering. Four exposure directions (North, South, East and West) were investigated. Experimental tests were performed fo...

Accelerated Weathering Performance of Impregnated Wood Samples Coated with Zinc by Means of Plasma-Assisted Particle Deposition
2016 - IRG/WP 16-30682
Many different methods are currently applied for wood protection against outdoor conditions. The most important of these is the process of impregnation with liquid substances. However, this kind of wood preservatives cannot provide a long-term protection of wooden surfaces. Weathering-resistant surfaces can be obtained by applying UV absorbing agents. In this study, the influence of zinc particles...

Exterior paint for the future - Will there be any dry-film preservatives left?
2017 - IRG/WP 17-50332
Wooden houses have a long tradition in several of the Nordic countries. Wood can be protected in various ways; constructional, chemically and by surface treatment. The use of various types of exterior paints as a surface treatment is a common way to prolong the durability of the wood. To further protect the painted surface against growth of fungi and algae, dry-film biocides remains an essential p...

The anatomical determination of wood samples found in the “Fürstengräber” from Lübsow (Poland)
2018 - IRG/WP 18-10930
The paper presents the results of anatomical research identifying three wooden fragments from the “Princes Graves” (“Fürstengräber”) in Lübsow, Poland. The research demonstrates that the wooden fragments are typical of wood harvested from European forests.
The physicals conclusions are important for the research of Jan Schuster, from the University of Lodz, Institute of Archeology, Pol...

Determining the natural durability on xylarium samples: mini-block test, wood powder and chemical profiling
2019 - IRG/WP 19-10944
Xylaria, or wood collections, can be considered sleeping beauties in terms of wood technological and biological output. In this study we focus on determining the natural durability of xylarium specimens from the Federal Xylarium in the Royal Museum for Central Africa. The Federal Xylarium contains over 80,000 specimens, covering more than 13,000 species, mainly from Central Africa. These specimens...

Suggestive remarks for designing of experimental samples and trial devices to treat wood by pre-vacuumed immersion method
2019 - IRG/WP 19-40862
This study was conducted to test the impregnability of wood material according to the pre-vacuumed immersion process and to reveal the usability of cylindrical (plug) samples in impregnation experiments in addition to the cuboid or cubic samples. In this context, cuboids were prepared 30 mm in length, 20 mm in width and 20 mm in thickness, whereas plugs were prepared radially and longitudinally wi...
