Wood Protection and Service Life Extension

Wood is a renewable, ecologically friendly material used on a large scale in building construction and furniture manufacturing, but its service life is short because of corners that can degrade it under ultraviolet (UV) radiation, humidity changes, and biological attack. This paper conducts experiments to compare the effectiveness of three protection tactics, namely, thermal modification of wood and acetylation and coating wood with nanotechnology, in enhancing wood durability. Accelerated weathering was observed in samples of beech (Fagus sylvatica) and pine (Pinus sylvestris), fungus resistance experiment and moisture absorption experiment. Thermal modification greatly improved the dimensional stability, and water uptake was minimised by a factor of 35 relative to untreated controls. Acetylated samples showed strong potential against fungal decay, with weight loss reduced by 60%. The use of nanoparticle-reinforced coatings containing TiO2and ZnO were shown to have good UV protection, maintain surface colour, and mechanical integrity in 1000 hours of exposure. The outcomes demonstrate that integrative modification methods can be successfully applied to enhance the service lifetime of wood and to provide sustainable, environmentally friendly technologies that replace traditional chemical preservatives and support the continued use of wood in modern engineering and eco-friendly building sectors.
