“…However, recent studies have revealed that bonding quality can be improved by treating straw with different chemicals and enzymatic methods that enhance surface wettability and increase the surface free radical concentration (Rowell et al 1997;Loxton and Hague 1996;Gomez-Bueso et al 2000;Karr and Sun 2000;Han et al 2001;Schmidt et al 2002;Zhang et al 2003;Li et al 2011).…”

The objective of this study was to evaluate properties of experimental particleboard panels manufactured from wheat straw that had been pretreated with acetic anhydride, soapy solution, hot water, or steam. Wheat straw particles were mixed with commercially manufactured wood particles at a ratio of 60%. Control straw particleboards with non-treated straw and wood particles were also produced. The results showed that the pretreatment of wheat straw significantly improved both the physical and mechanical properties of the straw particleboards. Panels made from wheat straw treated with a 9% solution of acetic anhydride or boiled in a soapy solution resulted in the highest mechanical properties, with an increase in bending strength values. Regarding internal bond strength, the samples made from wheat straw particles treated with acetic anhydride and a soapy solution had 2 and 3 times higher values, respectively, than those of non-treated samples. It seems that the pretreatment of wheat straw had a greater effect on the thickness swelling of the specimens than on their water absorption.

“…Initially, the use of cereal straws was regarded as difficult due to the wax layer covering the external part of the stem. Different methods of chemical and/or thermomechanical processing were proposed to remove this layer (Han et al 1998(Han et al , 1999Zhang et al 2003). The problem was considerably reduced through the application of isocyanate adhesives.…”

The Possibility to Use Long Fibres from Fast Growing Hemp (Cannabis sativa L.) for the Production of Boards for the Building and Furniture Industry

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.

“…OSB was manufactured from split straw with aspen strands or wheat straw (Han et al 2010(Han et al , 2012Cheng et al 2013). Particleboards were also manufactured with wheat straw (Boquillon et al 2004;Zhang et al 2003;Bekhta et al 2013) and rape straw (Dziurka and Mirski 2013). When manufacturing OSB from material such as straw, it is more difficult to achieve the properties required for OSB type 3 (EN 300 2006), due to lower mechanical resistance.…”

In this study, reducing the density of oriented strand board (OSB) in the core layer where strands were replaced by rape straw particles was evaluated. The use of rape particles in the core layer did not significantly affect the mechanical properties of OSB. This type of board had only slightly deteriorated properties compared with conventional OSB. However, with a decreasing density, significant changes occurred in the modulus of rupture (MOR) and modulus of elasticity (MOE) determined for the shorter axis. The lowest possible density value was determined based on statistical analysis, allowing for the production of OSB that met the requirements of EN 300 (2006) for OSB type 3. The analysis showed that panels of this type can be produced at a density of 530 kg/m 3 .
