Özet

Aim of the study: In this study, the influencing factors on the capability of adhesion in Uludag Fir (Abies bornmulleriana Mattf.), Chestnut (Castanea sativa Mill.) and Poplar (Populus tremula L.) woods were investigated Material and Methods: An important problem is that wood have different wettability that makes the bonding process difficult. Influence of PVAc-D3 and PU-D4 adhesives, which are widely used in the furniture industry, on wetting properties was evaluated by contact angle measurement analysis. Bonding strengths of the laminated veneers, which were untreated, treated in two hours at -20 degrees C and 60 degrees C temperatures, water immersion, and water vapor, were determined. Influence of adhesives on the wetting properties was evaluated by contact angle measurement analysis. The adhesion line to determine wettability was investigated with scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX). Main results: The results indicated that bonding strength of chestnut wood was determined to be higher than poplar and Uludag fir for all applications. The results generally showed that the applied treatments were resulted in a decrease in bonding strength for both types of adhesive. The lowest bonding strength was determined when the specimens were exposed to water immersion. The results clearly indicate that the surface wettability measurements were informative for forming of adhesion layers. According to the EDX analysis, a decrease of carbon and oxygen was observed in the transition from adhesive to wood. Research highlights: The adhesion capabilities were directly related to wood density and different treatment factors. The different wood species and adhesives used affected on wettability.
