Potential of Using Recycled Low-Density Polyethylene in Wood Composites Board
Journal Title: Tribology in Industry - Year 2011, Vol 33, Issue 1
Abstract
The aim of this study was to investigate the suitability of using recycled low density polyethylene (RLDPE) in wood board manufacturing. The composite board was produced by compressive moulding by increasing the percentage LDPE from 30 to 50wt% with interval of 10wt% at a temperatures of 140 and 180oC, pressure of 30-40 Kg/cm2 and pressing time 7-13minutes. The microstructure and mechanical properties: modulus of rupture (MOR), modulus of elasticity (MOE), Tensile strength, impact strength properties of boards were determined. The results showed that high modulus of rupture of 20.31N/mm2 and MOE of 1363N/mm2 were obtained from board produced at 140oC, 60/40wt% wood particles/LDPE content. The uniform distribution of the particles and the recycled LDPE in the microstructure of the composites board is the major factor responsible for the improvement in the mechanical properties. The results showed that the MOE, MOR meets the minimum requirements of the European standards, for general purpose. The boards produced had tensile strength that is within the requirement. Hence this LDPE can be used in board production for general purpose applications.
