Abstract


The goal of this work is to develop carpentry residues which are the kapok tree with tannic powders pod locust bean (Parkiabiglobosa), for the manufacture of particle board to seek palliative environmental problems of sawdust and the use of conventional binders. The work consisted firstly, to make particleboard with the sawdust of kapok tree by varying the percentage of tannic powder pod locust bean and secondly, to determine the physical and mechanical properties of particleboard panels made by means of three-point bending test, the tensile test, testing of internal bound, the water absorption and thickness swelling test. The bending test used to calculate the modulus of elasticity (MOE) which is between 7 840 MPa and 19 500 MPa modulus of rupture (MOR) varying between 6.84 MPa and 12.14 MPa. That of traction leads to the determination of Young's modulus (Re) in the range of 6 660 MPa to 19 869 MPa, also the modulus of rupture (MOT) varying between 19.16 MPa and 28.36 MPa, the internal bound (IB) between 0.294 MPa and 1.357 MPa. The threshold set by the ANSI A.1-1999 for MOE, MOR and IB standard, has been largely achieved. The values of density used to classify the particleboard panels of sawdust kapok tree in the categories of medium and high density. This shows that tannic powders of pod locust bean can validly replace conventional binders in the manufacture of particleboard.
