Manufacture and properties of binderless particleboard from bagasse I: effects of raw material type, storage methods, and manufacturing process

Abstract

Binderless particleboards were manufactured from sugarcane (Saccharum officinarum L.) bagasse by steam-injection pressing and by using hot pressing as a reference method. The inner layer (core/pith) and the outer hard fibrous layer (face/rind) of bagasse were used as raw materials. The effects of bagasse type, manufacturing process, and storage method on the mechanical properties of binderless particleboards were investigated. The results showed that the bagasse pith particles provided better board properties than bagasse rind particles. It seemed that bagasse pith particles were more easily deformed than bagasse rind particles, enlarging the bonding contact area. The severe conditions of steam-injection pressing caused delamination on the bagasse pith binderless boards with densities of 0.6 g/cm 3 or higher, and gave poor bonding quality. However, steam-pressed boards showed relatively higher board properties than hot-pressed boards. The storage method of sugarcane bagasse affected the chemical composition and the board properties. It was shown that the extent of self-bonding formation depends on the chemical and morphological properties of lignocellulosic materials, as well as on the manufacturing conditions.

Particleboard Panels Made from Sugarcane Bagasse: Characterization for Use in the Furniture Industry

“…Widyorini et al 13 assessed the quality of particleboard panels produced with sugarcane bagasse with and without medulla in association with some processing variables and obtained MOE values between 400 and 1600 MPa and MOR values between 2 and 11 MPa for static bending.…”

“…Mendes et al 7 , Freire et al 8 , Tabarsa 9 , Mendes et al 10 , Battistelle et al 11 , Barros Filho 12 , and Widyorini et al 13 have already assessed the use of sugarcane bagasse in the production of particleboard panels and their quality in comparison with panels made from other materials, and they found that boards made from sugarcane bagasse are very promising for furniture-based applications. In addition to adding value to the residue, the production of particleboard panels with sugarcane bagasse may be able to satisfy the growing demand in the wood panel industry for raw materials.…”

Effect of Post-production Heat Treatment on Particleboard from Sugarcane Bagasse

“…Some studies on the use of bagasse for the production of particleboard have revealed its significant potential 2,4,7,8,9,10 . However, because of its low density, a large amount of bagasse particles is required to form the panel, causing an increase in the compressive stress at pressing time and a greater number of hygroscopic sites, thus making the panel more susceptible to water absorption and dimensional change.…”

Development of Self-Bonded Fiberboards from Fiber of Leaf Plantain: Effect of Water and Organic Extractives Removal

“…Adhesive-free fiberboards can be manufactured whereby bonding is achieved through self-adhesion (Widyorini et al 2005a). During the fabrication process of such composites, the lignocellulosic fibers are thermo-compressed at high temperatures, generally above 160 °C (Bouajila et al 2005;Hunt and Supan 2006;Xu et al 2006).…”
