Evaluation of the mechanical and physical properties of particleboard manufactured from Canola (Brassica napus) straws

Abstract

This study examined possible feasibility of canola (Brassica napus) straws in the production of particleboard. Three-layer experimental particleboards with density 0,7 g/cm 3 were manufactured using different canola straws particle ratios (0%, 25%, 50%, 75% and 100%) and urea formaldehyde (UF) adhesive. Modulus of elasticity (MOE), modulus of rupture (MOR), internal bond strength (IB), water absorption (WA) and thickness swelling (TS) properties of the boards were evaluated and a statistical analysis was performed in order to examine possible feasibility of these straws in commercial particleboard manufacturing. The results indicated that, the addition of canola straws particle significantly improved modulus of rupture and modulus of elasticity of the panels and greatly reduced their internal bonding. Overall findings showed that most panels made from above-mentioned materials exceed the EN Standards for MOR, MOE and IB. Also, the water absorption and thickness swelling increased with increasing canola straws content in the panels. The experimental results have shown that production of general purpose and furniture grade particleboard used in dry conditions using canola straws is technically viable. The results of the study demonstrate that canola straws can be an alternative raw material source for particleboard industry.

Propiedades de tableros aglomerados de partículas fabricados con madera de Eucalyptus urophylla

“…Mendes et al (2014) indican que las perspectivas son bastantes positivas para el crecimiento a nivel mundial del sector de tableros de madera de forma general, siendo los tableros de partículas el de mayor consumo (57 %) del total, con un crecimiento continuo entre un 2 % a 5 % anualmente (Ashoria y Nourbakhsh 2008, Kord et al 2016).…”

Lignocellulosic Composites from Acetylated Sunflower Stalks

“…A variety of plants have been studied for use in composites manufacturing, including vine stalks [14], topinambour stalks [12,15], cotton stalks [16,17], coconut chips [18], bamboo chips [19][20][21], flax chips [22], and banana chips [23]. Other agriculture residues also include rice and wheat straw [24,25], canola straws [26], reed stem [27], date palms [28], oil palms and poppy husks [29], and stalks from cotton [30].…”

The quality comparison of particleboards produced from heartwood and sapwood of European larch

“…Many studies have been performed on the effects of various factors on the quality properties of particleboard. These factors are; the usages of various raw materials such as wood bark (Blanchet et al 2000), pine cone (Ayrilmis et al 2009), cotton (Gossypium hirsutum) stalks (Nazerian et al 2016), canola (Brassica napus) straws (Kord et al 2016), and needle litter (Nemli et al 2008), different parameters of the wood such as log position (Muhcu et al 2015), permeability of wood (Lyman 1969), anatomical and chemical properties of wood (Baharoglu et al 2013), moisture content of raw material (Baharoglu et al 2012), acidity of the particles (Akyuz et al 2010), wood extractives (Foster 1967), density of wood (Maloney 1977), mature and juvenile wood (Wasniewski 1989), and raw material growth region (Bardak et al 2017). The parameters of the particleboard production, such as dimensions of the particles (Motted 1967), residue type and tannin content (Moubarik et al 2013), paraffin application technique (Baharoglu et al 2014), hardener type, urea usage and conditioning period (Atar et al 2014), solid content of the adhesive and panel density (Sari et al 2013), decor paper properties (Bardak et al 2011), and shelling ratio (Nemli and Ozturk 2006) are investigated.…”
