The effects of surface coating and painting process on particleboard properties

Abstract

Aim of study: In this study, the effects of painting of particleboard surface by print press method (PrintPan), and coating with melamine resin impregnated decor paper (YongaLam) on board properties were investigated. Area of study: This study was conducted at the Kastamonu Integrated Particleboard Factory and Bartin University Faculty of Forestry, Department of Forest Industrial Engineering in Turkey. Material and Methods: Two groups of boards used in this study and one had 8 mm thickness and 680 kg. m(-3) density and the other had 18 mm thickness and 600 kg. m(-3) density. All boards were obtained from Kastamonu Entegre Company and surface painting and coating operations were performed its premises. Main results: Painting or coating of particleboard surfaces has been found to improve screw withdrawal, surface soundness, water uptake and thickness swelling properties. When the surfaces are coated with melamine-impregnated decor paper, it has been determined that the density, bending strength and modulus of elasticity in bending are increased. Research highlight: When the temperature, pressure and time applied in coating were higher than the normal panel production conditions, the internal bonds weaken and cause decrease on some strength properties. When the panel surfaces are painted by the print press method, it has been determined that the physical properties are improved.
