Heat treatment of wood strands for OSB production: Effect on the mechanical properties, water absorption and dimensional stability
2002 - IRG/WP 02-40238
The effect of heat treatment on the mechanical and physical properties of commercial OSB strands was evaluated. Heat treatment was applied under inert atmospheric conditions to wood strands. The aim of this study was to examine the heat treatment parameters to achieve significant reduction of thickness swelling (upon exposure to moisture in service) without causing excessive
reductions in stren...

A Vision for the Future
2002 - IRG/WP 02-20257
This paper focuses on the future of the pressure preservative treatment industry in North America, but also considers the potential role of aspects now considered peripheral. It puts forward the premise that the wood preservation industry risks extinction if it does not evolve. The driving forces for evolution are reviewed and the internal constraints are discussed. A number of alternative stra...

The efficacy of polyurethane coatings on wood samples exposed in the marine environment. Final Report -10 Year Assessment
1996 - IRG/WP 96-10170
The results of an IRG collaborative marine trial to investigate the long-term permanence and efficacy of polyurethane coatings against marine borers are reported. PU-coated wood samples were exposed at a range of sites from tropical to cold temperate locations. The marine borer species present at the sites included teredinids, pholads, limnoriids and sphaeromatids so that each site offered its own...

On the Influence of Wood Destroying Fungi on the Feeding Intensity of Termites
2017 - IRG/WP 17-10893
The baiting and feeding stimulating effect of wood attacked by fungal isolates of the species Coniophora, Lentinus, Poria and Gloeophyllum on termites Reticulitermes santonensis is examined. There are significant relationships between the activity of fungal isolates and the feeding behaviour of termites. The most active isolates can be used for increase the attractiveness of wood to wood-destroyin...

Encapsulated Active Ingredients for Wood Preservation
2017 - IRG/WP 17-30717
Encapsulated organic fungicides and termiticides have been examined for use as wood preservatives in vacuum pressure treatment of wood. Encapsulation of active ingredients was found to improve wood penetration behaviour and reduces leaching as well as biodegradation of the active ingredients compared to industrial standard formulations....

Radio frequency heating times for sterilization radiata pine solid piles
2017 - IRG/WP 17-40815
In this work was sterilized wood packaging material of radiata pine, stacked as solid piles without stickers, for determining the heating times using radiofrequency treatment. The experiments were performed in a radio frequency semi-industrial equipment. The results showed that the radio frequency heating times increases with wood volume and that radio frequency treatments were faster than convent...

Water sprinkled pine wood: A microscope study on boards showing streaking
1993 - IRG/WP 93-10033
Boards sawn from the outer sapwood of pine lumber previously water sprinkled for periods of 10-18 weeks and kiln dried, showed streaking after staining. Two types of enhanced stain uptake were noted: 1) a more concentrated and localized form after 10 weeks and 2) a more diffuse type which developed in later stages of water sprinkling. Areas showing enhanced stain uptake were examined using light a...

The effect of low molecular weight chelators on iron chelation and free radical generation as studied by ESR measurement
2000 - IRG/WP 00-10367
The focus of this work was to improve our current knowledge of the non-enzymatic mechanisms involved in brown-rot decay. Electron Spin Resonance (ESR), also known as Electron Paramagnetic Resonance (EPR), is an attractive technique for the identification and study of chemical species containing unpaired electrons (such as radicals and certain transition metal species). ESR spin-trapping techniques...

Utilization of plasma treatments in the field of wood protection
2021 - IRG/WP 21-40912
Plasma treatments have been used for modification of surfaces of wood and wood-based materials for some decades and solutions were developed to apply it for wood protection. This contribution aims to present the background, introduce the available plasma technology, and to give an overview on the typical applications and benefits....

Water-borne wood preservatives against marine borers. Results from NWPC marine trials started in 1972 and 1976
1990 - IRG/WP 4162
The paper presents the results from NWPC (Nordic Wood Preservation Council) marine trials started in 1972 and 1976. The trials are carried out according to the NWPC Standard No. 1.4.2.2./73 "Marine test - a test against marine wood boring organisms in sea water". The test site is Kristineberg Marine Biology Station on the west coast of Sweden. The wood blocks used in the trials were made from sapw...

The status of marine wood preservation in Papua New Guinea
1974 - IRG/WP 405
The life-expectancy of Papua New Guinea hardwoods in the marine environment has in the past been too short to be an economical proposition, a service life of six to twelve months being obtained from some of the timbers susceptible to marine wood borer attack. Consequently plans for wharves and other marine structures have specified the use of imported materials such,as steel and concrete. Due to t...

Comparison of the effect of different soil sources on the type and rate of decay of CCA-treated pine exposed in a soil-bed
1984 - IRG/WP 2213
The types of decay observed in CCA-treated pine posts in horticultural situations in New Zealand can be reproduced using a soil-bed exposure. Radiata pine stakelets, untreated or treated to 1.4, 2.7, or 5.4 kg/m³ with Tanalith NCA, were exposed to six different soil sources. The local nursery soil used for all standard laboratory tests was found to represent the greatest decay hazard to untreated...

Wood preservation in Turkey
1982 - IRG/WP 3216
The report reviews the forestry potential of Turkey and also the historical background of wood preservation in the country. The wood preservation industry in Turkey is mainly concentrated on the treatment of poles and railway sleepers. There is no official body responsible for wood preservation activities, and therefore its promotion depends mainly on the voluntary research efforts carried out by ...
