“…The results showed that the panels in group A were able to absorb a higher percentage of water in 24 h (54.5% to 64.5%) than those in group B (27.7% to 43.7%), similar values to those obtained in other studies of agriculture wastes [50,51]. A possible explanation could be the chemical composition of lignocellulosic materials, holocellulose containing a high amount of hydroxyl groups and has hydrophilic characteristics, capable of absorbing water, while the amount of cellulose in TOCS is lower than common wood, but its amount of hemicellulose is greater [52]. A second explanation relates to the particle geometry, TOCS particles are granule shape and smaller than wood particles; in general, the vast surface area of smaller particles may have contributed to the uptake of more water [46].…”

This study investigated the interaction between particle size and mixing ratio on the porosity of particleboard and in consequence its effect on the physical and mechanical properties of panels. Tea Oil Camellia Shell (TOCS), which could provide 1.8 million tons of lignocellulose raw material annually, can be a useful resource for particleboard production. In that regard, particleboards with different particle sizes (coarse and fine) and mixing ratios (wood and TOCS) bonded with Polymethylene polyphenyl polyisocyanate (pMDI) were investigated. The results showed that particleboard made with TOCS particles had higher densities than those of commercial wood particles. Furthermore, particleboards made with fine particles had lower porosity. The average values for physical and mechanical properties have shown that except for thickness swelling (TS), most properties were better with coarse particles. In terms of all properties, results showed that adding 50% of commercial wood in conjunction with TOCS particles regardless of particle size can offer acceptable results, which qualified all requirements of EN 312:2010 standard for P2-type particleboard (boards for interior fitments (including furniture) for use in dry conditions). In addition, due to the porous structure of the shells, TOCS-based particleboards have better thermal conductivity compared to wood-based particleboards.

“…In this sense, Narciso et al (2020) obtained reductions in the values of TP, MOR, and MOE with the gradual increase in contents of the coconut husk (0, 25%, 50%, 75%, and 100%), however, as they meet the minimum normative criteria, the authors state the possibility of producing particleboards using only coconut fiber.…”

“…The potential for using coconut shell in association with pine wood for the production of medium density particleboard was evaluated by Narciso et al (2020). Associating agricultural residues with wood for the production of panels adds value to the product, ensures proper disposal, and promotes satisfactory properties in the panels.…”

This research examined the influence of the compositions between coconut fiber (Cocos nucifera) and wood particles (Pinus taeda L. and Eucalyptus saligna) on physico-mechanical properties of homogeneous particleboards. The exploratory study was carried out under Tukey’s contrast test of means, at 5% significance level, with the following compositions: 100% coconut fiber (F100 P0 E0); 50% coconut fiber, 25% pine particles, and 25% eucalyptus particles (F50 P25 E25); and 50% of pine particles and 50% of eucalyptus particles (F0 P50 E50), with particle moisture content between 0% to 2% and 10%, in mass, of polyurethane-castor oil (PU-Castor) resin. Three panels were produced for each composition. The physico-mechanical properties such as density, moisture content, swelling in thickness after 24 h of immersion in water, perpendicular tensile strength, static bending strength, and modulus of elasticity were evaluated using standard methods. The results obtained indicated the potential for using coconut fiber for the production of homogeneous particleboards in view of the minimum criteria required by the normative documents, with emphasis on the physical property of swelling after 24 hours, which obtained a statistically equivalent average relative to the treatment that contained only wood particles.

“…Due to the depletion of wood resources for the production of wood-based panels, the use of lignocellulosic agricultural byproducts as a replacement, apart from attempts to use recycled wood-based materials [2], has become a promising alternative [3]. The most common byproduct, which is also rich in lignin and cellulose, are lignocellulosic particles from agricultural residues such as sugar cane bagasse [4], oil palm trunk [5], sugar beet pulp [6], tomato stalks [7], rice husk [8], corn stalk [9], maize cobs [10], coconut husk [11], kenaf stem [12], and waste biomass produced after orchard pruning [13]. In the production of commercial wood-based materials (particleboard, medium-density fiberboard, plywood or oriented strand board), synthetic adhesives such as urea-formaldehyde (UF), melamine-urea-formaldehyde (MUF), and phenol-formaldehyde (PF) are usually used due to their low production cost while maintaining excellent adhesive properties, excellent stability and fast curing [14].…”

Evaluation of Functional Features of Lignocellulosic Particle Composites Containing Biopolymer Binders

2021

View full text Add to dashboard Cite

In this research, the assessment of the impact of natural biopolymer binders on selected mechanical and physical properties of lignocellulosic composites manufactured with different resination (12%, 15%, 20%). Different mechanical and physical properties were determined: modulus of rupture, modulus of elasticity, internal bonding strength, thickness swelling, water absorption, contact angle, and density profile. Moreover, thermal properties such as thermogravimetric analysis and differential scanning calorimetry were studied for the polymers. The results showed significant improvement of characterized features of the composites produced using biopolymers. However, the rise of the properties was visible when the binder content raised from 12% to 15%. Further increase of biopolymer binder did not imply a considerable change. The most promising biopolymer within the tested ones seems to be polycaprolactone (PCL).
