Abstract

In this study, the capability of acetylated poplar particles with isocyanate and UREA FORMALDEHYDE RESIN in manufacturing particleboard of single-layer and three layers for studying the effects of these variables on SOUND ABSORBING COEFFICIENT, roughness and hardness of surface of manufactured boards, was investigated. The ACETYLATION degrees at high, medium, and zero (control) levels, type of resin (isocyanate and urea formaldehyde) and use place of acetylated particle that are composed 50 percent of board weight and are used either in surface layers or in all places of board, were considered as variables. The results indicated that use of ISOCYANATE RESIN in single-layer board with medium level acetylated particles in the major frequencies had high SOUND ABSORBING COEFFICIENT in comparison with the other boards. Not only SURFACE ROUGHNESS of boards is improved by increasing ACETYLATION degree in three layer board with ISOCYANATE RESIN in comparison with blanks with UREA FORMALDEHYDE RESIN but also SURFACE HARDNESS of board is increased. SOUND ABSORBING COEFFICIENT in the major frequencies on single-layer board with medium level ACETYLATION and with ISOCYANATE RESIN was the highest. The smoothest surfaces appeared on three layer board with high level ACETYLATION and with ISOCYANATE RESIN that had the hardest surface.
