Oriented Strand Board Production from Water-Treated Date Palm Fronds

Abstract

The objective of this work was to evaluate some of the important physical and mechanical properties of experimental oriented strandboard panels manufactured from four different cultivars of date palm (Phoenix dactylifera) fronds. Currently date fronds are considered as waste and under-utilized. Open burning and landfill are common practices for such resources. Therefore experimental panels were manufactured from strands washed with water to determine the effect of such treatment on panel properties. Bending characteristics, internal bond strength, thickness swelling, water absorption, and linear expansion along and across the grain orientations of the samples were tested. Based on the findings in this work, the internal bond strength values of the samples were found to be satisfactory. However, the samples manufactured from water-soaked strands had lower mechanical and physical properties as compared to those made from unwashed material. Water treatment also adversely influenced dimensional stability, namely thickness swelling, water absorption, and linear expansion of the samples. It appears that untreated date palm fronds as underutilized resource show promise sustainable raw material for the manufacture of oriented strandboard panels, but further research is required to maximize their potential.

Effect of Bamboo Species and Resin Content on Properties of Oriented Strand Board Prepared from Steam-treated Bamboo Strands

“…Thus, it could be concluded that in terms of the MOR parameter, the respective performances of OSBs from Betung and Andong were superior to those of the OSB from Ampel. Furthermore, the dry-state MOR values with 4% and 5% were superior compared to OSB from palm strand (Hegazy et al 2015). The mean values of wet-state MOR parallel and perpendicular to the surface grain ranged from 9 to 51 N/mm 2 and 11 to 32 N/mm 2 , respectively (Fig.…”

Effect of Date Palm Cultivar, Particle Size, Panel Density and Hot Water Extraction on Particleboards Manufactured from Date Palm Fronds

“…In our experiment, only the two class categories of D and E were used as they considered particleboard particles, which would be mentioned later in the text as coarse particles (class D) and fine particles (class E). Classes A, B, and C were considered as flakes and were used in another study for manufacturing oriented strand board [11].…”

“…Date palm fronds, having rich fiber content, were investigated to be used as raw material for experimental particleboard manufacture in several past works [8][9][10][11]. The four investigations above revealed that particleboard panels made from date palm fronds resulted in satisfactory mechanical and physical characteristics.…”

Potential Use of Phoenix canariensis Biomass in Binderless Particleboards at Low Temperature and Pressure

“…Particleboards have been generated using various species of palm trees as the main material such as date palm (Nemli et al 2001;Hegazy and Aref 2010;Amirou et al 2013;Saadaoui et al 2013;Hegazy et al 2015), Washingtonia palm (García-Ortuño et al 2013), and oil palm (Laemsak and Okuma 2000;Hashim et al 2011a;Rasat et al 2011;Suhaly et al 2012;Wad Nadhari et al 2013;Jumhuri et al 2014;Henao et al 2014;Tajuddin et al 2016). The behavior of the particleboard depends on the species of palm tree and the origin of the particles from the trunk or the leaf.…”
