Elaboración y evaluación de tableros aglomerados a partir de residuos agroindustriales de fibra de fruto de palma de aceite y cascara de mazorca de cacao usando una resina termoestable.

Abstract

In the present work, agglomerated particle boards were elaborated from agroindustrial residues of oil palm fruit fiber and cocoa shell husk, which represent a problem in the production chain of the palm and cocoa sector. A physicochemical characterization of the residues was carried out based on international regulations, in order to relate the values obtained with the final properties of the agglomerated boards. Likewise, variables were established within the process of elaboration of the boards such as the choice of particle size of the cocoa shell, compression pressure and resin / fiber quantities, after which mechanical tests were carried out to determine the quality of the Final product. The results obtained with respect to the modulus of elasticity show that the agglomerated boards from oil palm fruit fiber are better than those made with cocoa shell. Quality parameters such as water absorption and swelling in water after 24 hours show that from the oil palm fruit fiber (12%), agglomerated boards with similar or better specifications can be produced with respect to those made with Other lignocellulosic residues (rice husks, 16%). As a final result of the present investigation it is concluded that from the agroindustrial residues studied, it is possible to obtain a product with mechanical properties very close to the conventional agglomerated boards made with residues, proposing this system (residue / resin) as an ecological alternative and of low cost for the timber industry.
