“…Observing the results displayed on Figure 2, the CCB preservative increased physical and mechanical properties of wood panels, corroborating the result obtained by Ferro et al (2016). Other researches showed the CCB preservative do not influence physical and mechanical properties of wood engineered properties (Almeida et al 2019;Bertolini et al 2019). The use of CCB preservative, use of higher adhesive content and the interaction between these factors led to an improvement on panel performance, increasing dimensional stability, reducing the values of physical properties and enhancing mechanical properties, as showed on the statistical analysis already presented.…”

The present study aimed to characterize medium density particleboard manufactured with CCB treated particles of Pinus sp. wood specie and alternative mixed vegetal oil-base bicomponent polyurethane resin. For this, three different resin concentrations (10 %, 12 % and 15 %) were used in combination with the presence or absence of the CCB preservative, resulting in six distinct treatments. The particleboards were produced according the Brazilian Standard -NBR and evaluated according European standards -EN. The results met the requirements of NBR and EN. The technical feasibility of making panels with those materials used were proved and the quality of the product according to its performance were verified, indicating the possibility to use alternative bicomponent polyurethane resin from mix vegetal oil. Statistical analysis demonstrated that adhesive and preservative factors and the interaction between them were significant on physical and mechanical properties.

“…The thickness swelling decreased with the amount of resin volume fraction and increased with the quantity of chamotte volume fraction. Bertolini et al [32] obtained thickness swelling values of 4.27 and 4.11% for 2 h and 11.06 and 10.52% for 24 h, using a variation of 12 and 15% PU-castor. Mesquita et al [33] manufactured panels with açaí fruit fibers using bicomponent polyurethane resin based on castor oil and obtained thickness swelling of 13% for 2 h and 21% for 24 h for chemically treated fibers, and 20% for 2 h and 35% for 24 h for panels whose fibers were not treated.…”

The particleboard industry consumes large amounts of raw material, and this type of product consumption has been increasing over the last few years. The research for alternative raw materials becomes interesting, since most of the resources come from planted forests. In addition, the investigation of new raw materials must take into account environmentally correct solutions, such as the use of alternative natural fibers, use of agro-industrial residues, and resins of vegetable origin. The objective of this study was to evaluate the physical properties of panels manufactured by hot pressing using eucalyptus sawdust, chamotte, and polyurethane resin based on castor oil as raw materials. Eight formulations were designed with variations of 0, 5, 10, and 15% of chamotte, and two variations of resin with 10% and 15% of volumetric fraction. Tests of gravimetric density, X-ray densitometry, moisture content, water absorption, thickness swelling, and scanning electron microscopy were carried out. Through the results it can be noticed that the incorporation of chamotte in the manufacture of the panels increased the water absorption and the swelling in thickness, around 100% and the use of 15% of resin decreased, more than 50%, the values of these properties. X-ray densitometry analyzes showed that the addition of chamotte alters the density profile of the panel. In addition, the panels manufactured with 15% resin were classified as P7, the most demanding type on EN 312:2010 standard.

“…The use of engineered wood-based products, such as particleboards, medium-density fiberboard (MDP), oriented strand boards (OSB), and plywood panels has increased in rural structures, being an alternative to the use of sawn wood in buildings for structural use and ambiance, improving thermal and acoustic comfort in buildings ( (Bertolini et al 2019a;Bertolini et al 2019b;Garzón-Barrero et al 2016;Labans et al 2017;Scatolino et al 2017;Souza et al 2014;Zhou & Pizzi 2014).…”

Use of Residues From the Cellulose Industry and Sugarcane Bagasse in Particleboards

et al. 2021

The use of alternative materials such as lignocellulosic residues in the production of particleboards has increased considering that these residues are produced in large volumes and often do not have an appropriate destination. This research studied the use of residues from cellulose industries, sugarcane bagasse, and castor oil-based polyurethane resin in the production of wooden panels and evaluated the influence of using these residues on the physical and mechanical properties of the panels. The products were manufactured according to the Brazilian standard ABNT NBR 14810 and the requirements of the panels were evaluated based on national and international standards. All treatments partially met the regulatory requirements. The addition of bagasse led to an improvement in physical and mechanical properties, with treatment 2 (50% wood residue and 50% bagasse) presenting the best performance, which indicates the possibility of using panels with residues with non-structural purpose in environments to improve the thermoacoustic performance of rural buildings. The statistical analysis indicated that the percentage of bagasse was significant, improving the evaluated properties.
