Development of markers to predict decay durability of heat treated wood
2010 - IRG/WP 10-40496
Effect of heat treatment temperature on elemental composition of Scots pine sapwood (Pinus sylvestris) has been investigated in the range of temperatures between 220 and 250°C. Results revealed an important increase of carbon content, while oxygen content significantly decreases. Independently of the heat treatment temperature, elemental composition is strongly correlated with the mass losses due...

Charring of Norway spruce wood surface – an alternative surface modification technique?
2019 - IRG/WP 19-40870
Charring is an old wood surface treatment technique, mainly performed on wooden façade elements with the aesthetical aims, but also with the purpose of protection. This flame treatment method can be grouped into heat treatment processes. Below the top charred layer of damaged wood there is a layer which is during flame treatment exposed to high temperatures in anoxic or semi-anoxic conditions. Th...

Performance of a water-borne stain on beech, spruce, MDF and OSB improved by plasma pre-treatment
2020 - IRG/WP 20-40897
Coatings are an important part of wood protection, especially for outdoor applications. In order to provide a good protection, protective coatings need to exhibit good adhesion, mechanical resistance, and weathering resistance. Plasma pre-treatments are an established method to increase the performance of existing coatings including those on wood and wood-based substrates. Moreover, plasma deposit...

Silicate coatings for wood substrates
2020 - IRG/WP 20-40906
Silicate coatings are surface finishing products containing alkali metal silicates or ethyl silicates as main binders. They are traditionally designed and well established for mineral substrates or corrosion protection of steel. The interest for these coatings in wood field is growing because of the benefits they could provide such as high durability, weathering resistance and fireproofing and sus...

Hydrophilization of wood using a FE-DBD air plasma
2020 - IRG/WP 20-40907
One of the goals of surface protection of wood with coatings is to prevent the evolution of moisture in wood, which accelerates its degradation by abiotic and biotic factors. Good wettability of wood is a necessary pre-condition for sufficient protection with water-based coatings. Treatment of wood surface with atmospheric dielectric barrier discharge in configuration with a floating electrode was...

NewSiest-Enhancement of UV stability of thermally modified wood through envelope impregnation with nanobased stabilisers
2020 - IRG/WP 20-40909
Thermal modification is a process which improves the properties of wood, resulting in a material that can be disposed at the end of the product life cycle without presenting an environmental hazard. Thermally modified wood retains as a natural product and the grain, original colour variances and characteristics of wood are still present. However, exposure to daylight causes brightening or greying ...

Comparative study of the properties of silicate coatings with different mineral pigments (titanium dioxide, iron (III) oxide, copper (II) oxide) on the surface of wood
2022 - IRG/WP 22-40936
Silicate coatings are attractive alternatives to conventional organic-based coatings for wood protection. In this work, silicate coatings were prepared with a potassium silicate binder modified with a methyl siliconate solution, and three types of mineral pigments titanium dioxide, iron (III) oxide and copper (II) oxide. The coatings were applied on beech wood and cured under ambient conditions. T...
