Influence of Planer Shavings and Waste Particleboards Usage in Core layer on Physical and Mechanical Properties of Threelayer Particleboards
Abstract
The objective of this study is to investigate utilization of waste particleboards and planer shavings in
manufacturing three-layer particleboard panels. For this purpose, waste particleboards and planer
shavings were used in core layer of particleboard at different shelling ratios. Nine groups of three-layer
experimental boards with a target density of 0.65 g/cm3 were manufactured. Physical (thickness swelling
and water absorption) and mechanical properties (modulus of rupture, modulus of elasticity and internal
bonding strength) of the particleboards produced were determined according to EN standards. The results
have showed the mechanical properties of all the particleboards (excepted for B board group produced
from 100% waste particleboard) produced have satisfied the minimum requirements of mechanical
properties of particleboard defined in EN standards. Thickness swelling values of the experimental
particleboard for 24h water immersion were found lower than the maximum thickness swelling value of
particleboard in defined in EN standards.
