The Effect of Various Impregnating Agents on the Adhesion Strength of Solution Concentration Structure
Keywords:Timbercare Aqua, Impregnation, Adhesion Strength, Spruce wood, Wood/furniture industry
Water-based solvents and preservatives have been increasingly significant in terms of human and environmental health in this century. The effect of impregnated vacuum and diffusion time on the adhesion resistance of Spruce (Picea orientalis (L.) Link.) wood impregnated with Timbercare Aqua content and adhered with polyurethane glue was investigated in this research, and thus the areas of use in the wood industry were tried to be determined. The cuts were made according to the standards specified in the test sample preparation. All samples have been checked for fibrousness, smoothness, cracks, knots, and color flaws (fungus, rot, etc.). In determining the adhesion level, 100 x 50 x 30 mm test specimens were prepared and in determining the adhesion resistance change, it was carried out according to TS EN 205 standard (150 x 20 x 0.75 mm). According to the results of the experiments, the highest percent retention was achieved at 30 minutes vacuum and 40 minutes diffusion (2.78%), and the lowest was achieved at 30 minutes vacuum 50 minutes diffusion (1.96 %). The highest air dry specific gravity for 30 minutes vacuum and 50 minutes diffusion as 0.43 g/cm3), highest full dry specific gravity for 30 minutes vacuum and 50 minutes diffusion as 0.41 g/cm3), highest adhesion resistance for 30 minutes vacuum and 40 minutes diffusion as 2.70 N/mm2, at lowest adhesion resistance value for 30 minutes vacuum and 60 minutes diffusion as 2.61 N/mm2) was determined.
