Incorporation of raw boron minerals to protect particleboard against decay and mold fungi, termites and insects
2016 - IRG/WP 16-40729
This paper evaluated the biological performance of particleboards incorporated with the raw boron minerals ulexite and colemanite against decay, mold fungi, termites and insect larvae in comparison with that of particleboards with zinc borate, or boric acid plus a borax mixture. The results showed that ulexite and colemanite were highly effective against the decay fungi and termite attack in labor...

Five-year evaluation of a field trial of Eucalyptus grandis poles treated with zinc and boron
2017 - IRG/WP 17-30721
Round Eucalyptus wood treatment in sequential stages with inorganic borates and metal salts (zinc sulfate and boric acid+borax) was studied; the aims were to form an insoluble precipitate of zinc borate inside wood and to reduce treatment costs by performing the first treatment by simple ascent and diffusion of the preservative, at the same time as it was sought to impregnate the heartwood. The se...

Improvement of wood decay and termite durability resulting from combined treatments based on borax/phenol-formaldehyde impregnation followed by thermal modification
2019 - IRG/WP 19-40871
This study determined the factors influencing the boron content after leaching of pine blocks impregnated with aqueous solution of phenol-formaldehyde (PF) resin with or without borax and subjected to heat treatment by response surface methodology. An experimental design permits to analyze the effects of heat treatment temperature (150, 185 and 220°C), curing time (5, 12, 5 and 20 hours), resin c...

Effects of Borax and Boric Acid as Fire Retardants on the Resistance of Pterygota macrocarpa Wood to Fire Tests
2022 - IRG/WP 22-30770
The combustible nature of wood as a building material, when exposed to hazards of fire underscores the reason for fire retardant treatments. Pterygota macrocarpa wood is commonly used by builders in Nigeria for roof and other structural applications. Therefore, this study was carried out to assess the effect of Borax and Boric acid on the fire-retardant properties of P. macrocarpa wood. Wood sampl...

Binder-free, fire-resistant, light-weight fiberboard materials encrusted with expandable graphite and borax
2024 - IRG/WP 24-20714
Despite abundant data on innovative fire protection technologies tailored for wood and lignocellulosic materials, the prevailing approach revolves around the formulation of fire retardant solutions employing water-soluble salts, e.g., phosphorus or boron compounds. On the other hand, additives fostering the formation of a char layer during the combustion of lignocellulosic materials as a non-leach...

Preservative properties of boron-treated paulownia wood
2024 - IRG/WP 24-20729
This research was performed to investigate the preservative retention properties of paulownia wood treated using boric acid/borax at mass ratio of 1:1.8. Different portion of paulownia wood (top, middle, bottom) were used as a sample throughout of this study. In the treatment process, the paulownia wood was dipped in the 1% boric acid/borax solution for 1, 24, 72, 120 and 240 hours to achieve requ...
