“…The average values of the particleboards were lower than what is established (650 kg.m -3 ). This trend was also observed by Valarelli et al (2013) and Bazzetto et al (2019), as well as by Melo et al (2015), who observed a loss of adhesive and paraffin during panel manufacturing due to adhesion on the edges of the sizing machine and differences in the specific mass and moisture content of the particles used to make the panels. The particleboards showed average density (Table 3) of 550 to 750 kg.m -3 , which is in agreement with NBR 14810 (ABNT, 2006).…”

“…The basic density of the bamboo chips was 530 kg.m -3 ; a value corresponding to that found by Bazzetto et al (2019), and lower than that cited by Santos et al (2016), who obtained 600 kg.m -3 , but between the 400 kg.m -3 and 900 kg.m -3 reported by Berndsen et al (2010) and Anokye et al (2016). Therefore, the nominal compaction ratio obtained was 1.23 (650/530 = 1.23) and the effective compaction was 1.13 (600/530 = 1.13).…”

“…The values obtained for surface and top screw withdrawal (436.77 N and 485.45 N) were lower than the literature results. Nurhazwani et al (2016) found 499.9 N for SSW, while Bazzetto et al (2019) obtained 706 N for SSW and found 559 N for TSW. The average value obtained in the present work for the internal adhesion (0.65 MPa) was lower than the result obtained by Valarelli et al (2013) who found 0.98 MPa, but was higher than the values reported by Nurhazwani et al (2016) corresponding to 0.58MPa, and Bazzetto et al (2019) who obtained 0.25 MPa.…”

“…The authors found WA24h values of 68.8%. Bazzetto et al (2019) worked with bamboo particleboards (Dendrocalamus asper) testing four particle sizes. For panels produced with a particle size 0.50mm bonded with 10% UF adhesive, 1% paraffin emulsion, nominal density 650kg.m -3 , nominal thickness 15.70mm and the same press cycle parameters as those used in the present study obtained 34.3% and 42.2% for WA2h and WA24h, respectively.…”

“…Some studies have already analyzed the influence of this factor on the quality of panels such as: Torrell et al (2013), Lias et al (2014) and Farrokhpayam et al (2016). Studies by Azambuja et al (2015) and Bazzetto et al (2019) who analyzed the effect of bamboo particle size on the properties of the panels are also noteworthy.…”

Bamboo is a source of industrial raw material with wide geographical distribution. Brazil has good soil and climate conditions for its cultivation, in addition to existing reserves. Advantages of bamboo include: versatility, fast growth and good strength properties. One way of using this material would be as a raw material for manufacturing particleboards. Within this context, this article addresses an evaluation of the physical and mechanical properties of particleboards manufactured from bamboo particles (Dendrocalamus asper (Schult f.). Backer ex Heyne. Particles with 0.50 and 0.85mm granulometry and two conditions (control and treatment by immersion in hot water (70 ± 5 °C) for two hours) were used. Twelve homogeneous particleboards bonded with urea-formaldehyde adhesive with 10% solids were manufactured and the predetermined nominal density for all panels was 650 kg m-3. The properties analyzed were: water absorption, swelling and non-return rate in thickness, density profile, rupture modulus, elastic modulus, screw withdrawal and internal adhesion. Panels consisting of 0.50 mm granulometry showed higher water absorption rates, while panels made of particles treated with hot water and 0.85 mm granulometry showed higher swelling rates and non-return thickness. The panels made of treated particles showed higher density profile values in both layers of the panels. The granulometry did not influence the mechanical properties of the panels, and those with treated particles exhibited significant performance for the surface and top screw withdrawal properties, and internal adhesion. This last mentioned property reached the minimum value required by the standard. The results showed that it is feasible to use bamboo to manufacture particleboards, but it is necessary to adjust some variables such as nominal density, pressing parameters, adhesive content or the inclusion of a less dense material in the composition of the panels.

Adhesive application on particleboard from natural fibers: A review

et al. 2020

Impending health challenges in the formulations of particleboards from cellulosic-based waste particles such as wood chips, sawdust, and veneer boards are of great concern. These wastes are majorly bonded together with synthetic resin or binder in the presence of heat and pressure to produce particleboards of various specifications and sizes depending on the end-use. The qualities of the particleboards depend on the modification of the particle geometry, resin levels, board density, and manufacturing processes. The addition of special additives to enhance the qualitative performance of particleboards such as dimensional stability, fire retardancy enhancement, and moisture resistance is included in the manufacturing process. The milestone in the use of wood particles for particleboard manufacture is the large reduction in the environmental hazard that these abundant wastes cause. Furthermore, this review reports recent research efforts in the use of green adhesives to reduce the health threat related to utilizing formaldehyde-based particleboard. The use of adhesives produced from natural sources has contributed toward the reduction in the impending health challenges and the cost of building construction by using such a particleboard.
