Comparison of cubic and plug samples for preparation and data assembly in permeability study
2000 - IRG/WP 00-20197
In order to determine if plug experimental samples (PES: 30 x 15 mm2 diameter) could be used for inspection of wood permeability characteristics, radial and longitudinal flow directions were prepared according to either PES or cubic experimental samples (CES: 100 x 20 x 20 mm3) from the sapwood zone of Sitka spruce and treated by tanalith-C according to full-cell process. Results from the two prep...

A collaborative test to determine the efficacy of polyurethane coatings on wood samples exposed in the marine environment
1984 - IRG/WP 4113
Aims are: a) to determine the effectiveness of elastomeric polyurethane as a protective coating against marine wood boring animals in a range of tropical and tempreate sites; b) to compare the adhesion of polyurthane coatings on different wood species exposed in seawater; c) to record the severity of attack in failed samples and to identify the causal marine organisms....

Water-borne DNBP wood preservatives - Preparation and performance
1987 - IRG/WP 3407
Three waterborne wide-spectrum ground-contact DNBP (2-sec-butyl-4,6-dinitrophenol) wood preservative formulations and their performance are presented. Two are double-treatment formulations in which insolubilization and precipitation of the preservative is attained by salt formation or by formation of a water insoluble Cu/NH3/DNBP complex of formula [DNBP]2 [Cu(NH3)2]2 the clarified structure of wh...

Investigation of extracellular mucilaginous material in some wood decay fungi
1996 - IRG/WP 96-10188
The external morphology of the extracellular mucilagenous material (ECM) produced by Coriolus versicolor and Coniophora puteana during colonization of Scots pine and beech was studies using SEM. Specimens were examined in the frozen hydrated, freeze-dried and critical point dried state. All technics produced artefacts but the ECM was best preserved when examined the frozen hydated state. Critical ...

Protection of a low-density mangrove timber species gewa (Excoecaria agallocha) through preparation of particleboard – An Assessment
2006 - IRG/WP 06-40348
It is now well established that the conversion of low-density and low-cost timbers into laminated, composite and densified form is an alternative of wood protection by means of wood preservatives. Once only the timber species gewa (Excoecaria agallocha) was used for manufacturing newsprint paper in Bangladesh, which is not continued today. The feasibility of commercial production of particleboard ...

Preparation of Copper Rosinate Emulsion and Its Resistance against Wood Decay Fungi
2013 - IRG/WP 13-30619
A leaching-resistant water-borne copper preservative was prepared by means of the following three steps: (1) Gum rosin was saponified with potassium hydroxide. (2) The soap reacted with copper sulfate to form copper rosinate. (3) The copper rosinate was emulsified with a mixture of Tween 20 and Span 80. Poplar (Populus ussuriensis) wood was impregnated with 0.5%, 1.0%, 1.5%, or 2.0% of the copper ...

Preparation and characterization of activated carbon fibers prepared from liquefied wood
2013 - IRG/WP 13-40636
Activated carbon fibers were prepared from liquefied wood through stream activation. The effects of activation temperature and time on the microstructure and surface functional groups of the liquefied wood activated carbon fibers (LWACFs) were studied using analysis of burning behavior, X-ray diffraction, nitrogen adsorption-desorption isotherms, X-ray photoelectron spectroscopy, and SEM. The resu...

Preparation of Calibration Standards for the Analysis of Pentachlorophenol in Treated Wood by X-ray Fluorescence
2016 - IRG/WP 16-20591
The primary purpose of this project was to develop a method for preparing calibration standards that can be used by the wood treating industry to calibrate X-ray fluorescence instrumentation. Calibration standards of penta/P9-oil in southern yellow pine that cover the retention range of 0.2 to 0.9 pcf (0.6 to 1.9 %) were successfully prepared. A detailed procedure for mixing penta in treating sol...

The Study of the Preparation of Overlaid MDF with the Flame Retardant Impregnated Paper
2018 - IRG/WP 18-40848
The preparation of overlaid medium density fiberboard (MDF) was studied. The flame retardant impregnated papers (FRIP) were overlaid on the surface of the MDF for the fire protection. The results showed that: 1) The production of the FRIP was based on the technology of melamine-impregnated paper, which required the viscosity of the impregnated resin lower than 20s. However, with the addition of th...
