Abstract: In this study, beech wood (Fagus silvatica L.) has been chemically modified with citric acid (Acidum citricum) and sodium hypophosphate (SHP) as the catalyst and gradually thermo-condensed in the dryer. Afterwards, wetting angle, surface energy, and shear strength of glued joints of modified and unmodified wood were determined. Testing of the bond strength according to standard EN 204 and comparison between modified and unmodified samples were executed. The adhesive used for bonding samples was polyvinyl aceta… Show more

“…Acid has a strong destructive effect on wood. The use of acid can degrade cellulose and hemicellulose in wood, its degradation products dehydrate and generate furfural substances and this material can be produced under hot-pressing conditions of the polymer which can play the role of an adhesive so that the wood is glued [ 4 ]. The size of the crystalline zone of cellulose, the degree of crystallinity and the orientation of microfibrils in each wall layer of the cell have a strong influence on the elasticity of the cell wall.…”
