INVESTIGATION ON THE POSSIBILITY OF PARTICLEBOARD PRODUCTION FROM LIGNOCELLULOSIC SOURCES IN SOURTHERN REGION OF IRAN (2) REPORT 2: THE POTENTIAL OF DATE PALM RESIDUES AND PROSOPIS (MESQUITE) WOOD IN PARTICLEBOARD INDUSTRY

In this experiment the optimum condition of particleboard uom Date palm residues and prosopis (Mesquite) produced in southern part of Iran was investigated. Variable factors as type of raw-material (Date palm and prosopis), resin content (9, 10 and 11 percent) and press time (5, 6 and 7 minutes) and...

Sumario:In this experiment the optimum condition of particleboard uom Date palm residues and prosopis (Mesquite) produced in southern part of Iran was investigated. Variable factors as type of raw-material (Date palm and prosopis), resin content (9, 10 and 11 percent) and press time (5, 6 and 7 minutes) and total of 18 combinations of variables were investigated.Other factors such as type of resin (UF), hardner content (2 percent) type of hardner (NH4CI)press closing time (4.5 mm/sec.), board density (0.7gr/cm3) press pressure (30 kg/cm2) and press temperature (160 C) were held constant.All boards were tested according to DIN-68763 standard. The factorial experimental design at completely random blocks test was used. The results of this study could be summarized as follows: Increasing the resin content from 9 to 11 percent increased MOR, MOE and ID and decreased thickness swelling after two and 24 hours immersion in water.The highest internal bond (IB) was related to prosopis (Mesquite) boards made at 5 minute, prass time. As far as production of date plam and prosopis (Mesquite) wood is concerned, the results revealed that the polymerization of resin and wood is better at 11 percent resin content and 5 minutes of press time. Date palm residues are important with treatment process according to reference. NO. One. Shape and dimension of chipped and flaked particles of date palm residues are important, because type and characteristics of species are different, in the mean time, as date palm residues has very high bulk density and specific surfaces than prosopis (Mesquite) which it has inverse effect on both physical and mechanical properties, thus it should be considered during the process of particleboards production.
