Comparisons of differences in electrical conductivity and corrosivity between CCA-oxide and CCA-salt treated wood
1981 - IRG/WP 3178
CCA preservatives have served well in many applications throughout the world. In developed areas it is the preservative in demand for clean dry paintable surfaces with long durability. In developing areas it is widely used for economic and logistical reasons. With the current emphasis on energy resources, the CCA preservatives are gaining greater acceptance as a substitute for hydrocarbon-related ...

The effect of wood preservatives on the relation between the electric resistance and moisture content in scots pine (Pinus sylvestris L.) sapwood
1998 - IRG/WP 98-20142
The effect of two types wood preservatives (TBTO and CuHDO) on moisture content measurements with an electric resistance meter in pine sapwood is assessed. High and low concentration impregnated pine sapwood is climatized at different relative humidities. Once climatized the samples are weighed and the moisture content is measured with an electric resistance meter by fixed stainless steel, isolate...

The fate of salt preservatives in facility yard soils and decontamination of soils and drainage waters
1993 - IRG/WP 93-50001-25
Extensive studies during the past 10 to 15 years revealed that noticeable amounts of preservative components may be released in the environment by dripping off or by rain prior to fixation unless adequate precautions are taken. Therefore, soil and groundwater contamination especially from chromium-VI compounds but also from other inorganic and organic constituents exist in impregnation plants, pos...

Study of properties and application of Paulownia in wood industries
2011 - IRG/WP 11-40560
Important of required raw material supply regarding constraint in harvesting, increasingly population, change in consumption pattern and increasingly focus on wood products and per capita in consumption is obvious for anyone. Paulownia is a marvelous tree species with its characteristics of fast-growing, good Wood quality, multiple uses, wide-ranged distribution, easy propagation, deep root system...
Copper naphthenate treatment for wood pols - a review and update
2012 - IRG/WP 12-30600
This paper reviews copper naphthenate (CuNap) and its utility as a treatment for wooden utility poles. One of the principal reasons that CuNap has gained market acceptance, in addition to its efficacy against decay fungi and wood-destroying insects, is its low mammalian toxicity. CuNap is a well-proven non-restricted use preservative, used extensively and specified for environmental reasons by ut...

Effect of silver nanoparticles on the rate of heat transfer to the core of the medium-density fiberboard mat
2014 - IRG/WP 14-40653
Effect of silver nanoparticles on the rate of heat transferred to the core section of medium-density fiberboard (MDF) mat was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg based on the weight of dry wood fibers; the results were then compared with the control MDF panels. The size range of silver nanoparticles was 30-80 nm. Res...

Increasing the hardness of wood-composite panels by nanosilver
2016 - IRG/WP 16-40715
Effect of silver nanoparticles on hardness in medium-density fiberboard (MDF) was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg, based on the dry weight of wood fibers; the results were then compared with the control panels. The size range of silver nanoparticles was 30-80 nm. Composite mats were hot-pressed for 6, 8, and 10 m...

Effects of Nano-Wollastonite Impregnation on Fire Properties of Some Thermally-Treated Solid Wood Species
2017 - IRG/WP 17-40771
The effects of nano-wollastonite (NW) suspension impregnation on the fire-retarding properties of heat-treated solid wood of three species (beech, poplar, fir) were studied. Heat treatment was performed at two temperatures of 180 °C and 200 °C. Impregnation was carried out at a pressure of 3 bars for 30 min. The fire properties included ignition time, glowing time, back-darkening, back-splitting...
