“…Nevertheless, not much is known about combining wood particles with alternative raw materials in particleboard manufacturing. Yalinkilic et al (1998) consider that the utilization of raw materials with greater durability for composites manufacturing would decrease environmental and health risks caused by the application of chemical preservatives.…”

The resistance of particleboards, made from wood, bamboo and rice husk, to fungi and termites was evaluated. Panels were composed of 100% wood (Eucalyptus grandis), 100% bamboo (Bambusa vulgaris), 100% rice husk (Oryza sativa), 50% wood and 50% bamboo; and 50% wood and 50% rice husk. Panels exposed to the decay the brown-rot fungus (Gloeophyllum trabeum and the white-rot fungus (Trametes versicolor), and, in a choice feeding trial, to termites (Nasutitermes corniger). The rice husk particleboards had the highest resistance of all samples and the bamboo particleboards had the lowest resistance. T. versicolor fungi produced a larger mass loss in the particleboards than did G. trabeum.

“…Entre estos residuos se tienen productos forestales como la madera, las hojas, las raíces (Bufalino et al, 2012) y los desechos agroindustriales como las fibras vegetales (Y S, and J Y, 2011). En el mundo de la construcción se aprovechan el cemento, los agregados y demás escombros; en la industria polimérica se reutilizan los termoplásticos post consumo, los elastómeros recuperados y las fibras animales, entre otros, los cuales según sea el caso, mejorarían el comportamiento mecánico, físico, químico, biológico, térmico e incluso óp-tico de la materia prima que se quiera transformar (Schmidt et al, 1994;Felton and DeGroot, 1996;Kamdem and Munson, 1996;Vick et al, 1996;De Souza et al, 1997;Yalinkilic et al, 1998;Wolfe and Gjinolli, 1999;Huang and Cooper, 2000;Kartal and Clausen, 2001). En el presente trabajo se abordó el desarrollo de paneles aglomerados, los cuales a diferencia de los propuestos por el mercado actual, se elaboraron a partir de polvillo de aserrín como sustituto de las astillas convencionales, lo que le da valor a este residuo maderero que se encuentra en gran cantidad y del cual no se saca beneficio en la industria de paneles aglomerados.…”

ResumenEl propósito del presente estudio es investigar el comportamiento mecánico y físico de tableros aglomerados, compuestos por polvillo de aserrín y resinas melamínica-urea formaldehído (MUF) en los que se introdujeron cargas de materiales recuperados como caucho sintético, fibra de vidrio y fibra de yute. Se estudiaron algunos parámetros como la relación molar M/UF, la resistencia a la tracción, la resistencia a la flexión, la gravedad específica, la absorción de humedad y el hinchamiento después de 2 y 24 horas de inmersión en agua. Los resultados experimentales arrojaron valores máximos de resistencia a la tracción y a la flexión de 10,9 MPa y de 48 MPa respectivamente, con una razón molar M/UF de 1,5. La temperatura de trabajo fue de 150 °C y el tiempo estimado por prensado fue de 150 s.Palabras clave: Tableros aglomerados de partículas, aserrín, residuos industriales, resina melamínica, resina urea-formaldehído, resistencia a la tracción, módulo de ruptura, material compuesto. AbstractThe purpose of this study is to investigate the mechanical and physical behavior of fiberboard composed of sawdust and Melaminica-Urea Formaldehyde (MUF) resins in which loads were introduced of some recycled materials such as: the synthetic rubber, fiberglass and jute fiber. Some parameters were studied such as M/UF molar ratio, tensile strength, flexural strength, specific gravity, moisture absorption and swelling after 2 and 24 hours of immersion in water. Experimental results yielded maximum values of tensile strength and flexural strength of 10.9 MPa and 48 MPa, respectively, with an M/UF molar ratio of 1.5. The working temperature was 150 °C and pressing the estimated time was 150 s.

Flax shive and hemp hurd residues were characterized, and the feasibility of manufacturing three-layered particleboards was evaluated using 2.5% and 5% polymeric diphenyl methane diisocyanate resin loadings. The flax shive and hemp hurd residues had lower bulk densities and higher aspect ratios compared with the wood residues. Their higher aspect ratios offered greater overlap in bonding, which led to consistently higher bending properties that exceeded the American National Standards Institute (ANSI) requirements for low-density (LD2) particleboard and, in some cases, medium-density (M2) particleboard. Because of their particle geometry, the flax shive and hemp hurd particleboards also showed minimal linear expansion with changes in the moisture content at 20 ± 3 °C and between 50% and 90% relative humidity. The high absorption capacity of the flax shive and hemp hurd residues resulted in higher thickness swell and water absorption properties than the wood residues. The results indicated that low-density flax shive and hemp hurd particleboards (500 to 620 kg/m 3 ) can be manufactured using isocyanate resin quantities as low as 2.5% to produce panels that conform to ANSI specifications with a greater mechanical performance than that of wood residue particleboards.
