Relative efficacy of various oxine copper formulations against brown-rot fungi
2019 - IRG/WP 19-30741
This paper investigates the relative resistance of three different oxine copper formulations (oil-borne, water-borne, water-borne with pH-adjustment) as a preservative treatment for wood against brown-rot fungi. Impregnated southern pine sapwood cubes were exposed to R. placenta and G. trabeum cultures in a soil-block test. After eight weeks, the weight losses of the cubes were examined in relatio...

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...

Sterilization of Large Timbers during Preservative Treatment: How Quickly We Forget
2020 - IRG/WP 20-40902
Air seasoning is a common method of moisture management in utility poles and is done de facto during pole storage prior to treatment. However, extended air drying prior to treatment encourages fungal attack and can facilitate establishment of decay fungi in poles before a protective preservative barrier is applied. This problem can be mitigated by proper air-seasoning methods coupled with heat ste...

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...

Treatability of South African-grown Eucalyptus grandis with water-borne copper azole and disodium octaborate tetrahydrate wood preservatives
2021 - IRG/WP 21-40920
This study investigated the treatability of the sapwood and heartwood of sawn Eucalyptus grandis with copper-azole (CuAz) and disodium octaborate tetrahydrate (DOT) water-borne preservatives towards improving its durability for enhanced use in structural solid wood applications. The results obtained showed that, at a moisture content of 12 ± 1%, sawn E. grandis sapwood can be impregnated to a mea...

Eradication of beetles attacking wooden historical buildings by humidity-controlled warm-air treatment
2023 - IRG/WP 23-11028
Humidity-controlled warm-air treatment is a method that kills mainly beetles that are damaging the wood. In this process, a heat-insulating and airtight covering is placed around the object building, and the temperature inside the covering is gradually raised to about 60°C, held for a certain period of time, and then gradually lowered. While maintained at 60°C, all forms of damaging insects - ad...
