Utilization of Bone Adhesive to Produce Particleboards from Stems of Cotton Plant at the Pressing Temperature of 140°C

Problem statement: To value agricultural residues, a study was carried out to investigate mechanical and physical properties of particleboards produced from stems of cotton (Gossypium hirsutum L.) by using bone adhesive. Approach: In order to obtain particleboards with minimum physical and mechanical properties as required in the conventional standards for general purpose particleboards, the optimum pressure temperature and the optimum pressure time and density used in this study, were respectively 140°C, 10-15 min and about 0.6-0,671 g cm⁻³. The optimum value of bone adhesive used in particleboards was 10%. The Modulus Of Elasticity (MOE), Modulus Of Rupture (MOR), Traction strain (R_r) and water absorption were determined at the pressure temperature of 140°C. Results: The results revealed that the density of particleboards obtained from cotton plant at 140°C have neither notable influence on their mechanical properties, nor evolve in the same way as the constant mechanics of the particleboards. Conclusion: The bone adhesive could be used in particleboards production from the chips of cotton instead of the conventional binders which create the environmental problems.
