Effect of pretreatment of wood surfaces with a copper monoethanolamine solution on the natural weathering performance of semitransparent stains
2019 - IRG/WP 19-40881
Semitransparent stains for wood products are favored for outdoor applications in Japan because these finishes do not hide the wood grain. However, the photoprotective effects of wood surfaces are low, therefor there is a need to improve the weathering performance. We examined the natural weathering performance of semitransparent stains on wood pretreated with a copper monoethanolamine solution (Cu...

Disposal of treated wood - Canada
1990 - IRG/WP 3563
It is estimated that treated wood removed from service each year in Canada contains about 16,000 tonnes of creosote, 1000 tonnes of pentachlorophenol and 245 tonnes of CCA or ACA. The amount of CCA treated wood for disposal is expected to increase more than ten-fold by the year 2020. At present, most treated wood is disposed of in landfills, burned (creosote only) or recycled as other products. Ot...

Estimation of the population of a sound colony of Coptotermes lacteus (Froggatt)
1988 - IRG/WP 1353
Selecting an area with a high termite hazard is deemed essential in locating field sites in order to screen potential termiticides and wood preservatives. Yet, quantifying termite populations in such sites remains imprecise. There are major problems associated with estimating populations of termites in mound colonies (either free-standing or in trees), and these are briefly discussed. In this pape...

Estimates of wood-consumption rates by termites
1983 - IRG/WP 1201
Effects of 2 components; termite-biomass and experiment duration on estimates of wood-consumption rates (mg wood/g termite/day), were examined. Three models; (1) no mortality, (2) linear mortality and (3) nonlinear mortality were used to calculate mean standing-crop biomass of termites. Model (1) predicted a significantly lower wood-consumption rate than those based on models (2) and (3). No signi...

Sample Origin Influencing the Leachability of Wood Preservatives
2011 - IRG/WP 11-20474
The aim of this study is to see if the raw material influences fixation and leachability of wood preservatives. Moving towards more eco-friendly and –concious society, the wood industries must adjust itself to new rules and regulations. Greener solutions in wood protection are being tested and introduced, older systems are being improved, but questions still arise concerning some elements curren...
