Abstract

The aim of this study was to determine the effects of different bleaching chemicals and their treatment time on glossiness, color stability, and surface roughness of wood. Spruce (Picea orientalis L.) and oak (Quercus sessiliflora Salisb.) wood specimens were bleached with aqueous solutions of 25% hydrogen peroxide (H2O2), 25% ammonia (NH3), and their mixture (1:1;volume:volume) for 10, 20, and 30 minutes immersing. Glossiness of wood specimens parallel and perpendicular to grain values were measured with Glossmeter at 60-degree incident angle. Color measurements and surface roughness were wade according to ISO 7724 - 2, and ISO 4287 standards, respectively. Results showed that the highest glossiness decrease (0.99) was observed in oak wood treated with ammonia solution perpendicular to grain for 20 min. immersing. The highest total color chance (18.88) was observed in oak wood treated with ammonia solution for 30 minutes immersing. All bleaching solutions increased the surface roughness of wood specimens.
