Biological durability of natural fibre reinforced composites
2014 - IRG/WP 14-40681
Composite materials reinforced with wood or non-wood natural fibres have the potential to be a lighter and lower-cost alternative construction material. Until better availability and properties and a lower cost price of degradable polymers makes their use more prevalent, the application of natural fibre reinforcements in synthetic polymers is an intermediate step towards products that are complete...

Effect of Nano-Silane on Permeability in MDF as a Result of Susceptibility to Moulds and Fungi
2016 - IRG/WP 16-40716
Effects were studied of vapor chamber on specific gas permeability of nanosilane-treated medium-density fiberboards (MDF). Size range of nanoparticles was 20 – 80 nm. Nano-silane (NS) 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. Specimens were kept for 18 weeks in vaporized chamber; their specific gas ...

Decay Resistance of MDF Manufactured with Huntite- Hydromagnesite and Zinc borate
2017 - IRG/WP 17-30710
The objective of this study was to evaluate the effectiveness of some mineral based fire retardants on decay resistance of Medium density fiberboard (MDF). Two mineral based chemicals containing (Huntite/Hydromagnesite) and zinc borate (ZB) were used at two different concentrations for panel manufacturing. Decay test of samples was performed according to EN 113 standard method. At the end of the t...

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...

Performance of a water-borne stain on beech, spruce, MDF and OSB improved by plasma pre-treatment
2020 - IRG/WP 20-40897
Coatings are an important part of wood protection, especially for outdoor applications. In order to provide a good protection, protective coatings need to exhibit good adhesion, mechanical resistance, and weathering resistance. Plasma pre-treatments are an established method to increase the performance of existing coatings including those on wood and wood-based substrates. Moreover, plasma deposit...

Investigating the fire properties of a composite material made of MDF-residues, citric acid and sorbitol
2023 - IRG/WP 23-40969
In times of climate change and a shortage of energy and raw materials, it has become apparent, that material reuse of wood in a cascade system can reduce the ecological impact of a material and be cost effective. A new composite material has been developed made from citric acid, sorbitol, water and waste MDF. Not only will there be a material reuse option for waste MDF but due to the small particl...

Fungicidal properties of black liquor from the waste MDF board digestion in terms of wood protection
2023 - IRG/WP 23-50379
The aim of the work was to determine the fungicidal properties of black liquor as a product of the chemical digestion of waste MDF board. The resistance of wood treated with black liquor from MDF waste pulping process was compared with the resistance of wood treated with black liquor from the pulping process of a by-product from agricultural production. The control material consisted of non-treate...
