Wooden Pallet Preservation Wood Basics

Wood has been one of the earliest natural materials used by humans and remains a renewable and biodegradable resource among the world's four major materials (steel, concrete, wood, and plastic). It boasts a low density, high strength, vibration resistance, low thermal and acoustic conductivity, excellent electrical insulation, shock resistance, durability, elasticity, and toughness, as well as beautiful color and grain. Its health, environmental friendliness, and ease of processing make it an ideal building and decorative material for both indoor and outdoor use. Moreover, due to its renewable nature, wood is also an eco-friendly building material. With the depletion of global forest resources, the rational use of wood as a renewable resource must prioritize the sustainability of forests to maintain global ecological balance and extend the lifespan of wood, which has always been a goal of modern wood and construction industries. Vacuum pressure treatment is widely adopted in developed countries like the United States, Japan, and Europe as an effective wood preservation technique; it effectively prevents the侵蚀 of various molds, termites, marine borers, and microorganisms. Preservative-treated wood includes species like Siberian pine/larch (Russia), Southern pine (USA), twisted pine (Canada), Norway pine (Finland and Sweden), and radiata pine (New Zealand). All except the Siberian pine, which is a naturally mature forest with a lifespan of 70-100 years, are mostly人工 forests and fast-growing plantations. In general load-bearing wooden structures, bridges, wooden houses, and piling in marine and underground environments should avoid or minimize the use of wood from artificial and fast-growing plantations due to their loose texture and high variability.
