Dimensional stability and biological resistance of particleboard from acetylated albizzia wood particlesWood Research.(76): 49-58


Abstract 

Dimensional stability and biological resistance of low-density acetylated particleboards from tropical fast-growing and perishable timber, Albizia falcata, were investigated. Acetylated particles with 18% weights gain (WG) were pressed into particleboards using phenol formaldehyde (PF) resin and isocyanate (IC) resin for adhesives. Control boards made with PF adhesive swelled faster and to a greater extent than did control boards containing IC adhesive. Boards made from acetylated particles showed greater reduced rate and extent of swelling after water soaking test or dry/wet treatment for both types of adhesives as compared to control boards. Acetylated particleborads subjected to burial in moist unsterile soil were virtually unchanged in color and texture with little weight loss showing the potential performance in severe biological conditions.

Loot, Geraldine; Aldana, Marcela; Navarrete, Sergio A., 2005: Numerous ecological studies have demonstrated the dramatic effects that humans have on coastal marine ecosystems. Consequently, marine reserves have been established to preserve biodiversity. Recent reviews show that this strategy has paid off because inside reserves, most species have rapidly increased in size and abundance. Even though these s...
