Decay Resistance of Maple (Acer Insigne) Wood Against White Rot
2010 - IRG/WP 10-10740
In this study, the decay resistance of maple (Acer insigne) in natural state and treated with ACC (Acid copper chromate) was investigated against the white rot fungus (Coriolus versicolor). ACC is a kind of water borne preservatives that was used in this study for treating specimens under vacuum and pressure (Bethell procedure) with 3 percent concentration. In conducting mentioned evaluation, koll...

Fungal decay resistance and mechanical properties of plywood panels made from maritime pine (Pinus pinaster) and bonded with cornstarch-quebracho tannin-phenol formaldehyde adhesive
2010 - IRG/WP 10-40490
The aim of this work is to demonstrate the performances of cornstarch-quebracho tannin-based resins designed as adhesive in the plywood production. In this way, the cornstarch and quebracho tannin was introduced in the classic adhesive formulation in order to supply a part of phenol-formaldehyde (PF). In order to evaluate the mechanical performances of optimal cornstarch-quebracho tannin-PF, plywo...

Durability of heat treated Malaysian bamboo Gigantochloa scortechinii strips
2010 - IRG/WP 10-40514
Bamboo is one of the fastest growing plants and can be used for various products. In tropical countries such as Malaysia bamboo is abundantly available at reasonable prices, therefore it is used for numerous purposes. However, bamboo (as a lignocellulosic material) is susceptible to fungal and insect attack and it is difficult to protect by preservative treatment. Heat treatment is an option to im...

Biological and mechanical performances of particleboard panels made from maritime pine (Pinus pinaster) and glued with cornstarch-mimosa tannin-urea formaldehyde adhesive
2011 - IRG/WP 11-40542
The objective of this work was to demonstrate the utility of cornstarch-mimosa tannin-based resins designed for application as an adhesive in the particleboard production. Bond qualities of cornstarch-mimosa tannin- urea formaldehyde (UF) (10:4:86, weight ratios) resins and commercial UF resin were assessed by using an automatic bonding evaluation system, prior to production of particleboard panel...

Coconut lumber for wood decks (Cocos nucifera L.): decay resistance against Basidiomycetes fungi
2012 - IRG/WP 12-10784
Since a couple of years, manufactured products of coconut wood for outdoor uses like wood decks have been proposed on the European market. These are presented as an alternative for traditional tropical timbers. In the past, coconut wood was neglected and burned for sanitary reasons and lack of interest at industrial scale. Plantation coconut trees at end of production of copra constitute a renewab...

Effect of Nano-silver and Nano-copper and Nano-zinc oxide on Paulownia wood exposed to white-rot fungus
2013 - IRG/WP 13-30635
Paulownia is known as a fast growing tree and it can be used in several applications. The present study investigated the effect of Nano-silver and Nano-copper and Nano- zinc oxide on resistance of Paulowina (Paulownia fortunei) wood against the white rot fungus (Coriolus versicolor). Wood specimens with a dry density of 0.37g/cm3 were impregnated with a 400 ppm aqueous suspension of micronized na...

In vitro fungicidal activity of Tunisian essences extracts against Coriolus versicolor and Coniophora puteana
2014 - IRG/WP 14-20544
Bark of six Tunisian species including cork oak (Quercus suber L.), eucalyptus camaldulensis, alder (Alnus glutinosa), Aleppo pine (Pinus halepensis), nut pine (Pinus pinea) and Chelfi pomegranates (Punica granatum) were tested against two rot-fungi: Coriolus Versicolor (for leafy trees) and Coniophora Puteana (for conifers) according to an adaptation of the European guidelines (NF EN 113, 1986). ...

Ammoniacal zinc borate as solid wood preservative
2014 - IRG/WP 14-30659
Zinc borate, well-known for its fungicidal, insecticidal and flame resistant properties, is widely used in manufacture of lignocellulose particle board. This form of borate is the least water soluble form available providing advantages as well as disadvantages for use as a wood preservative. This form does not leach from wood under conditions of high humidity, but it is also very difficult to appl...

Effectiveness of Gleditsia triacanthos heartwood extractives as wood protector
2019 - IRG/WP 19-10950
In Uruguay, Gleditsia triacanthos (known as honey locust) is an exotic tree species categorized as invasive; it produces severe ecological impact as it displaces native species, causing changes in the structure of the native forest community. Being extremely difficult to control, it is widely distributed through Uruguay and neighbouring countries. However, one way to mitigate its negative impact i...

Effect of nanoparticle impregnation on the biological durability of wood
2022 - IRG/WP 22-30772
This study evaluated the efficacy of five different nanoparticles (zinc-oxide, zinc-borate, silver, copper-oxide, copper-borate) applied with different concentrations against the brown rot Coniophora puteana and the white rot Coriolus versicolor. The generally effective nanoparticle treatments were the combinations containing borate in its chemical structure. However, only zinc-oxide and silver na...
