Characteristics of Fiberboard Manufactured from Recycle Paper Sludge

This paper presents the results on a study to use recycle paper sludge for fiberboards production. 20-40 mesh paper sludge fiberboard and unclassified paper sludge fiberboard were fabricated. Four factors, panel density, adhesive content, pressing temperature and time, were used. The bending strength, internal bonding and thickness swelling were investigated. The results indicated that the mechanical properties of the boards were positive affected by the panel density. The 20-40 mesh paper sludge fiberboards gave superior internal bonding and thickness swelling than the unclassified paper sludge fiberboards. The bending strengths of the unclassified paper sludge fiberboards were much more than those of 20-40 mesh paper sludge fiberboards. The internal bonding and thickness swelling of all type fiberboards satisfied fully the requirements set by GB/T11718-2009 standard.
