Effect of paraffin application technique on the physical and mechanical properties of particleboard

Abstract

The main objective of this study was to investigate the effect of paraffin application technique on the quality properties of particleboard. The paraffin was applied to the wood particles in three different techniques: (1) before resination, (2) after resination, and (3) with resin. The modulus of rupture, modulus of elasticity, internal bond strength, thickness swelling, surface roughness parameters, contact angle, and formaldehyde emission of the boards were determined. Statistical analysis showed that paraffin application technique had a significant influence on all properties of particleboards. The boards made using technique (1) had the highest mechanical properties and lowest surface roughness, formaldehyde emission and contact angle values. The worst properties were obtained from the board made using technique (2).
