Abstract

The main goal of the present research is to investigate the possibility of recycling agricultural residues for producing different types of pressed wood. All experimental work was conducted using a mixture of wood saw dust + linen sass + corn stalks with equal percentages, to produce samples of different types of pressed wood. The main experiments were carried out to control and study the effect of some different operating parameters (pressing pressure (1, 3, 5, 7 MPa), pressing time (5, 10, 15, 20 min.) and resin type (Urea formaldehydes and Speria formaldehyde) affecting the pressed wood production processes. The produced pressed wood was evaluated taking into consideration physical properties (Density, thickness swelling and water absorption), mechanical properties (Modulus of elasticity, modulus of rupture, and internal bond strength) and final product quality. The obtained data reveal that the produced pressed wood quality were meeting the required physical and mechanical properties as stated in the standard quality guidelines under conditions of 5 MPa pressing pressure and 15 min.. pressing time with the use of  urea formaldehyde resin. The findings also illustrated that by controlling both pressing pressure and pressing time, a mixture of wood saw dust + linen sass + corn stalks with equal percentages could be used to produce different types of pressed wood (Particleboards, PB; Medium density fiberboards, MDF and High density fiberboards, HDF).
