“…Table 3 shows the relatively high swelling and soaking susceptibility of the boards. Although no substance was applied to improve the hydrophobicity of the boards, the values observed were much greater than the values noted in laboratory tests on chipboards or OSB boards Dziurka et al 2015). The swelling of boards A_3 and B_5 did not exhibit statistically significant differences, and these values were lower than the swelling of the other boards.…”

a This paper describes an attempt to use long fibres from fast growing hemp (Cannabis sativa L.) as a raw material for the production of boards for the building and furniture industry. Hemp fibre boards with densities of 300 to 1100 kg/m 3 were studied. The board surfaces were finished using a one-cycle method in which birch veneers were pressed to make the boards. The pulp was glued with pMDI (9 wt.% based on dry weight). The basic mechanical and hydrophobic properties of the boards were tested. The static bending strength and modulus of elasticity of the boards with a density of about 650 kg/m 3 were comparable to P2 furniture boards. Only the higher density boards had adequate properties that met standards for the building industry, which were comparable to those of OSB/3 and MFP boards. Hemp fibre boards were characterised by relatively good water resistance, which was manifested by low swelling and low soaking susceptibility.

“…This can be due to the higher contact area between particles and decrease in the empty spaces between them (Zheng 2006). In addition, decrease in porosity that is the main factor of water absorption improves the resin's performance (Dziurka et al 2015). When temperature increases, hemicellulose chains are destroyed, and when OHgroups are destroyed, fibers, and hence the boards, are less hydrophilic.…”

The current study aims to improve properties of particleboard manufactured from cotton (Gossium hirsutum) stalks glued with urea formaldehyde. To this aim, panel density (at three levels: 0,5; 0,65 and 0,8 g/cm 3 ), press temperature (at two levels: 150 and 180 °C) and press closing speed (at two levels: 4 and 8mm/s) were selected as independent variables. The mechanical properties consist of modulus of rupture, modulus of elasticity and internal bonding and physical behaviors such as water absorption and thickness swelling of panels were determined. Results showed that with increasing the density of panels and press temperature modulus of rupture, modulus of elasticity and internal bonding of panels increased, while bending strengths of panels were differently affected by press closing speed compared to the internal bonding, so that with increasing the press closing speed modulus of rupture increased, but internal bonding decreased. Moreover, increasing panel density and press temperature, water absorption and thickness swelling of panels decreased. The press closing speed affected the water absorption and thickness swelling, insignificantly.

“…Requirements of sustainable wood management make it necessary to search for alternative raw materials for manufacture of particleboards. Some of the well-established alternatives include annual crop residue as a substitute of wood chips in particleboard production (Boquillon et al 2004, Czarnecki and Dukarska 2010, Azizi et al 2011, Dukarska et al 2011, Dukarska et al 2012, Park et al 2012, Dziurka et al 2015, de Melo et al 2015, Kord et al 2016. Utilization of annual crop residue brings obvious benefits, such as reduced wood consumption having a positive effect on board prices, as well as management of plant-origin waste.…”

This study analyzed feasibility of manufacture of composite particleboards resinated with a mixture of phenol-formaldehyde resin and 4,4′-methylenediphenyl isocyanate in the weight ratio 70:30. For this purpose 3-layer particleboards were produced with varying shares of Kraft scrap paper pulp in the core. Experimental boards were manufactured applying 0, 10, 15, 25, 50 and 75% substitution of wood chips with Kraft paper pulp. Analyses were conducted to determine physico-mechanical properties of boards, i.e. bending strength, modulus of elasticity, internal bond before and after the boiling test and swelling in thickness after 24 soaking in water. Based on recorded testing results it was stated that moisture resistant composite boards manufactured with a 25% substitution of wood chips with Kraft paper pulp meet the requirements of the EN 312 standard for boards used in humid conditions in terms of their strength and moisture resistance specified in the internal bond after the boiling test. 162 Universidad del B í o -B í o Maderas.
