Wood modification refers to various processes that enhance the properties of wood, making it more durable, stable, and resistant to environmental factors. Techniques include chemical treatments, thermal processes, and the use of additives. These modifications can improve wood's resistance to moisture, insects, and decay, extending its lifespan and usability in construction and furniture. Common methods of wood modification include heat treatment, which involves heating wood to high temperatures to alter its structure, and acetylation, where wood is treated with acetic anhydride to improve its dimensional stability. These processes help create wood products that perform better in diverse applications.
