Termite Resistance of Different Wood Panels Treated with Bifex® under Laboratory and Field Trials
2011 - IRG/WP 11-10745
The effects of Biflex® on termite resistance of laminated chip Board, MDF (Medium Density Fiber), Ply Wood and Veen Board at 50 ppm were evaluated. Laboratory and field trials resistance tests showed that all woods treated with Biflex were resistant to termites as compared to untreated ones. It was concluded that as chemical loadings increased, termite mortalities increased, and at the same time...

The resistance to Basidiomycetes fungi of chipboard 35 years after their industrial preservation with wood preservative on fluoroborate basis
2011 - IRG/WP 11-40546
The research on wood-based panels’ (WBP) behaviour towards fungi impact demonstrated rather low resistance of wood-based materials to wood rotting fungi. However, these materials are used in construction under conditions favourable to fungi growth. In such conditions WBP treated with wood preservatives should be used. Preservation durability is of great importance in such cases. The resistance o...

Evaluation of an optimized industrial process aiming to improve the natural durability and mechanical behavior of bamboo for outdoor use
2011 - IRG/WP 11-40554
Mao Bamboo (Phyllostachys pubescens) is characterized by high contents of sugar and starch and by high hygroscopicity, which makes it susceptible to biodegradation, and specifically to fungal decay. Still, many bamboo based products regularly enter the European wood construction market, competing with traditional solid wood products used for outdoor decking and cladding. The performance of a heat ...

Preliminary laboratory bioassay to evaluate engineered Fibre-boards against subterranean termites C. acinaciformis (Isoptera: Rhinotermitidae)
2012 - IRG/WP 12-10768
In Australia, laboratory bioassays with subterranean termites typically contain groups of workers and soldiers in a substrate of moist mound material. This termite substrate may affect termite consumption, and the test materials create a favorable termite condition for the test. The main purpose of this test is to examine the effect of a melamine formaldehyde treatment of wood panels to evaluate t...

Effects of Nano-Zycosil on Liquid and Gas Permeability of MDF
2012 - IRG/WP 12-40578
Effects were studied of zycosil nanoparticles, with size range from 30 to 90 nm, on liquid and gas permeability of medium density fiberboard. 100 g of nanozycosil was added to each kg of dry fibers. Density was kept constant at 0.67 g/cm3. The obtained results indicated that addition of zycosil to the mat resulted in a significant increase in gas permeability due to the lower fiber-content in the ...

Nano-Zycosil in MDF. Part I: Gas and Liquid Permeability
2014 - IRG/WP 14-40652
Effects were studied of zycosil nanoparticles, with size range from 20 to 80 nm, on liquid and gas permeability of medium density fiberboard. Nanozycosil was used at four consumption levels of 0, 50, 100, and 150 g/kg dry wood fibers. Density of all treatments was kept constant at 0.67 g/cm3. The obtained results indicated that the addition of zycosil to the mat resulted in a significant increase...

Effect of silver nanoparticles on the rate of heat transfer to the core of the medium-density fiberboard mat
2014 - IRG/WP 14-40653
Effect of silver nanoparticles on the rate of heat transferred to the core section of medium-density fiberboard (MDF) mat was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg based on the weight of dry wood fibers; the results were then compared with the control MDF panels. The size range of silver nanoparticles was 30-80 nm. Res...

Study of weathering Characteristics in Profiled and Treated Deck Boards
2014 - IRG/WP 14-40680
Wood exposed outdoors to repeated wetting and drying develops surface checks. Excessive checking of wooden deck boards has been a major source of dissatisfaction to consumers. In this study, Southern pine (Pinus sp.) deck boards were machined to flat (control) and ribbed surface profiles. The specimens were treated with aqueous formulations of 4,5-dichloro-2-N-octyl-4-isothiazolin-3-one (EL2) and ...

Douglas-fir PSL Treated with Oilborne Copper Naphthenate – Treatment Experience & Efficacy
2014 - IRG/WP 14-40687
Treating characteristics, field stake efficacy and the results from treatment trials for oilborne copper naphthenate (CuNap) and Douglas-fir parallel strand lumber (PSL) are summarized in this paper. Treatment with a P9 Type-C based solution in laboratory tests showed full cross section penetration of large cross sections could be achieved. Commercial treatment trials using a P9 Type-A solution ...

The resistance of composite boards protected with azole and inorganic nanoparticles to basidiomycetes and moulds
2015 - IRG/WP 15-40688
This paper presents a study on the resistance of wood composite boards, glued with silicone adhesive and obtained from chips of Scots pine Pinus silvestris L. and willow Salix viminalis L., to basidiomycetes and mould. The boards were protected in the production processes with fungicides based on metal nanoparticles, as well as on derivatives of 1,2,4-triazole, benzimidazole, and thiazole. The bio...

Increasing the hardness of wood-composite panels by nanosilver
2016 - IRG/WP 16-40715
Effect of silver nanoparticles on hardness in medium-density fiberboard (MDF) was studied here. A 400 ppm aqueous nanosilver suspension was used at three consumption levels of 100, 150, and 200 mL/kg, based on the dry weight of wood fibers; the results were then compared with the control panels. The size range of silver nanoparticles was 30-80 nm. Composite mats were hot-pressed for 6, 8, and 10 m...

2018 - IRG/WP 18-10935
Field trials of efficacy of soil termiticides available in Thailand were started back in the 1980s at four different locations representing different unique weather types of the country. The method used in the trials (Modified Ground Board Test) is the compulsory test for every soil termiticides aiming to be registered for termite control in Thailand. The ongoing record reveals that some particula...
