Sorption properties of wood impregnated with aqueous solution of boric acid and montan wax emulsion
2010 - IRG/WP 10-40492
Non-biocidal techniques for wood protection become more and more important, nowadays. One of the possible treatments is use of water repellents. In the present research influence of, one of the possible water repellent, the montan wax emulsion, on the moisturizing and the sorption characteristic of impregnated wood was investigated. To achieve a better protection against wood decay fungi, montan w...

Wood Protection in Croatia – Situation from the Acquisition of Independence till Today
2010 - IRG/WP 10-40501
In the last eighteen years in Croatian wood-working industry, respectively wood protection industry, many good changes happened. In such a short period of time Croatian industry changed their “product philosophy”. After the fatherland war and acquisition of independence the most logs and sawn wood products have been exported from Croatia. With such “kind of philosophy” Croatian wood-workin...

Wood protection by means of electro osmotic pulsing technology (PLEOT)
2010 - IRG/WP 10-40505
Wood protection is mainly based on chemical protection of wood. The disposal of wood preservative treated material causes restrictions in its later use or recirculation into the eco-cycle. A new protective system, electro-osmotic pulsing technology on wood, called PLEOT, is tested in a fungi test and in soil contact. Mass loss and moisture content of Scots pine sapwood samples was calculated after...

Towards designing eco-friendly buildings with in-built termite protection
2010 - IRG/WP 10-50273
The increase in greenhouse gases, leading to global warming, is considered by a consistent scientific worldview not due to natural variation, but due to the growing concentration of carbon dioxide (CO2), methane (CH4) and other atmospheric pollutants. Global emissions of carbon dioxide from fossil fuel combustion and cement production rose from 22.6 billion tons in 1990 to an estimated 31.2 billio...

Tannin resin-boron for outdoor wood protection and fire retardancy
2011 - IRG/WP 11-30567
Boron in the form of boric acid is well known for its efficacy against wood destroying organisms, as well as for its high leachability from treated wood when in outside exposure. Moreover, due to the European directive 2008/58/EC, boric acid is only authorized at low levels. In order to keep considering boric acid as an interesting active ingredient for wood protection, the issue is now to fix it ...

Design, synthesis, characterisation and effectiveness of ‘Locked-in-Boron’ chemicals for H3.2 level of wood protection
2011 - IRG/WP 11-30577
Boratrane molecules with five-membered and six-membered molecular ring systems, and with various ring substituents were synthesised, characterised and formulated for wood treatment for accelerated laboratory bioassays using wood decay fungi as test organisms. Six-membered ring boratranes showed lower efficacy in laboratory assays than five-membered ring boratranes. One alkyl-substituted boratran...

The Significance of Natural Durability of Croatian Mediterranean Wood Species for their Traditional and Present Protection Methods and Use
2012 - IRG/WP 12-10770
The aim of this article is to contribute to the better cognition of the protection and use of some most important Croatian autochthonous Mediterranean wood species. Their traditional use and protection are observed by two aspects. The first one is the presence of these species in the Croatian Mediterranean regions for many centuries, and the long tradition of their use, regardless of their natural...

Use of the durable species Coast Redwood as a reference system for field testing of Wood Protection systems
2012 - IRG/WP 12-20486
Data is provided and discussed for a number of field exposure tests where the naturally durable wood species Coast redwood, Sequoia sempervirens, was included along with untreated pine and standard preservative treatments. In general, there is potential for higher variability of results with this naturally durable species, but it does suggest that redwood can be a useful reference material for te...

Performance of Wood Protection Systems at Multiple Field Test Sites Using the Ground Proximity Test Method
2012 - IRG/WP 12-20499
A series of preservative systems were used to treat southern pine ground proximity test samples which were then exposed at a range of test sites located throughout the world. The sites were chosen on the basis of having vastly different Scheffer Climate decay indices. After almost 14 years exposure, distinct differences are apparent in how different preservative systems perform at the different ...

Wood protection in the Sierra Nevada National Park, Venezuela
2012 - IRG/WP 12-50290
The use of wood without the respective protection inevitably leads to its replacement. When this wood is used in a national park call attention to public opinion because the consequences generated by the very short life service, and replacement is required, means more wood not preserved, rapidly deteriorated in a constant repeated cycle. This becomes an environmental problem, especially when the ...

Wood-leather panels – A biological, fire retardant building material
2012 - IRG/WP 12-40615
The poor flame retardant properties of wood-based products are among the severest obstacles, hindering its use in the commercial building sector. Recently, some attempts to improve the fire properties, relying on inflammable salts or reactive halogen compounds, have been presented, although they either cause problems with machining or embody harmful compounds (halogen derivates).
In this paper, ...
