Development of composite furniture using bamboo strips, bamboo mat and rubber wood veneer
2014 - IRG/WP 14-40679
Bamboo offers cost-effective component in panel form is well suited to wood substitute can be used as furniture components. In the present study, borak (Bambusa balcooa ) bamboo were used for manufacturing bamboo panel. Mitinga (B. tulda) bamboo were used for making mat and rubber wood veneers were used for manufacturing mat overlaid veneer board. Borax-boric acid (BB) treatments were given to enh...

Development of a new characterization method to analyse Cypermethrin penetration in wood material by immunolabelling
2015 - IRG/WP 15-30674
The preservative efficacy of organic biocides is strongly related to their capacity of penetration and retention within wood tissues. The specific detection of the pyrethroid insecticide cypermethrin is currently obtained after extraction followed by chemical analysis by chromatography techniques. However visualizing the insecticide molecule within the wood structure requires specific probes toget...

Outcomes deal to impregnability of Eucalyptus globolus L. wood after microwave treatment
2015 - IRG/WP 15-40712
Microwave treatment of wood has been used with several aims in many studies as drying, enhancement of pulp properties, angle fibre detecting, density evaluation, etc., and also to improve permeability of wood. Eucalyptus globulus Labill. is a refractory species which is spreading its use as solid wood for construction in Spain. Studies of different ways to improve their impregnability (uptake and ...

Above-ground performance of a buffered amine oxide treatment system against Mastotermes darwiniensis
2016 - IRG/WP 16-10855
Above-ground H2 field tests against Mastotermes darwiniensis were conducted in far north Queensland to assess the efficacy of buffered amine oxide treatments in the softwoods Pinus sylvestris and P. radiata, and the hardwoods Eucalyptus regnans and E. diversicolor. Untreated hardwoods and slash pine bait wood (P. elliottii) were severely attacked or destroyed, while untreated P. sylvestris was mod...

Use of small volume cups in XRF analysis of treated wood retention
2017 - IRG/WP 17-20602
Efforts are underway in the United States to improve the conformance of commercially-treated wood with the applicable retention standards. As part of an effort to devise a practical method for on-site assessment of within-charge retention variation, we investigated whether small-volume x-ray florescence (XRF) sample cups could be used with treated wood. A range of cup sizes, preservative types, re...

Overview of the treated wood quality control program in the United States with the recent challenges and advances
2017 - IRG/WP 17-20616
In the past two decades, there have been significant and rapid changes in wood protection technologies for residential applications which have moved away from long established heavy duty metal oxide based products such as chromated copper arsenate (CCA). The successor generation of wood protection systems usually contain copper as the primary biocide, in combination with carbon-based co-biocides s...

Possibility of using lichen (Usnea filipendula) and mistletoe (Viscum album L.) extracts as potential natural wood preservative
2017 - IRG/WP 17-30712
Increasing environmental pressures on toxic chemical wood preservatives lead to the development of natural and environmentally friendly wood preservatives. In this study, using possibilities of lichen (Usnea filipendula) and leaves of mistletoe (Viscum album L.) as potential natural wood preservative were researched. Treatment solutions have been prepared with two different solvents, water and met...

The Effects of Pre-Microwave Treatment on Retention Levels And Some Mechanical Properties of Spruce Wood Treated with CCA
2017 - IRG/WP 17-40800
Microwave (MW) treatment of wood has been evaluated in recent years for different purposes by several scientists. Microwave conditioning improves permeability, reduces density and heat conductivity and changes dimensional stability. Furthermore, it could even improve the permeability of refractory wood species such as spruce and Douglas fir. In this study, MW pre-treatment was applied to spruce wo...

Treatability of South African-grown Eucalyptus grandis with water-borne copper azole and disodium octaborate tetrahydrate wood preservatives
2021 - IRG/WP 21-40920
This study investigated the treatability of the sapwood and heartwood of sawn Eucalyptus grandis with copper-azole (CuAz) and disodium octaborate tetrahydrate (DOT) water-borne preservatives towards improving its durability for enhanced use in structural solid wood applications. The results obtained showed that, at a moisture content of 12 ± 1%, sawn E. grandis sapwood can be impregnated to a mea...

A six-year ground proximity trial of TRU-CORE treatments at Innisfail, Queensland
2023 - IRG/WP 23-30775
This article describes an H3 (above ground outdoor) ground proximity field trial that compares the performance against decay fungi of TRU-CORE (also known as the Buffered Amine Oxide Enhancement System) Copper Quat (CQ) with CCA and commodity Alkaline Copper Quat (commodity-CQ) treatments, all in Pinus radiata. The retentions achieved reflected commercial practice, where higher mean retentions are...

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...

Levels of chromated copper arsenate in aged radiata pine vineyard posts
2024 - IRG/WP 24-50389
At the Centre for Timber Durability and Design Life, Australia a cooperative project is underway with Forest and Wood Products Australia, supported by a consortium of timber producers, chemical suppliers and timber users to identify alternative pathways for treated timber and EWP’s. Under this initiative, we are focusing on establishing the current and forecasting future volumes of treated timbe...
