Worldwide in-ground stake test of acetylated composite boards
1997 - IRG/WP 97-40088
Acetylated wood composite stakes are being tested in ground contact (graveyard test) in seven fields around the world. Three types of acetylated wood composites were prepared: spruce fiberboard in Sweden, aspen fiberboard in Madison and rubber wood particle board in Indonesia. Two levels of acetylation were used, a high level of ~20% acetyl content and a low level of 10% acetyl content. Control bo...

Termite and fungal resistance of in situ polymerized tributyltin acrylate and acetylated Indonesian and USA wood
2000 - IRG/WP 00-30219
Wood [Indonesian pine (IP), Indonesian Jabon (IJ) and USA southern yellow pine (USP)] was either in situ polymerized with tributyltin acrylate (TBTA) or acetylated and then exposed to termite and fungal degradation both in laboratory tests and field exposure. The TBTA woods had an average weight percent gain (WPG) of 11% for IP, 12% for IJ, and 10% for USP. The acetylated woods had a WPG of 15-27%...

Field Trials with mini-stakes
2002 - IRG/WP 02-20244
In 1995 an extensive field test program with wood mini-stakes, 8 x 20 x 200 mm, was started. In these trials a large number of parameters are being evaluated, including several new wood preservatives, differently chemically modified woods and natural durability of various wood species. The test sites are three fields in Sweden for in-ground and “close to ground” testing, one subterranean termi...

Evaluation of Commercially Available Polyurethane Resin to Develop Non-biocidal Wood Preservation Treatments
2016 - IRG/WP 16-40751
Evaluation of commercially available polyurethane (PU1 and PU2 and polyisocyanate (PNCO) to develop non-biocidal wood preservation treatments have been conducted. A simple method by vacuum impregnation of these resins into beech wood (Fagus sylvatica L) and pine wood (Pinus sylvestris L.) samples followed by varied curing process at ambient temperature, 103oC, and 200oC have been performed. Based ...

Termite resistance of wood-plastic composites made with acetylated wood flour, coupling agent or zinc borate
2018 - IRG/WP 18-10917
There is little published scientific literature on the laboratory or field testing of wood-plastic composites (WPC) against termite attack. Therefore, the objective of this research was to investigate termite resistance (both laboratory and field) of 5 different extruded WPC blends of 50% western pine wood flour (WF) and high-density polyethylene (HDPE), and untreated pine solid wood. The study in...

Mechanical and biological durability properties against soft-rot and subterranean termite in the field (grave-yard test) of beech wood impregnated with different derivatives of glycerol or polyglycerol and maleic anhydride followed by thermal modification in an opened or in a closed system
2021 - IRG/WP 21-40917
This paper presents mechanical and biological durability properties in soil beg test (soft-rot test) and field test (grave-yard test) against subterranean termite of the wood modified with an aqueous vinylic derivative of glycerol/polyglycerol or maleic anhydride cured in an opened or in a closed system. Wood modification was performed through impregnation of European beech (Fagus sylvatica) with ...

Improvement of durability of Scots pine against termites by impregnation with citric acid and glycerol followed by in situ polyesterification
2023 - IRG/WP 23-30777
Scots pine (Pinus sylvestris) sapwood samples were impregnated with solution containing citric acid (CA) and glycerol (Gly) followed by heating 140 °C according to already described procedure (L'hostis et al. 2018). The resulting modified woods were then used to evaluate the effect of chemical modification on the durability against termites. Two kinds of experiments were conducted for this purpos...
