Log cabins are typically outdoor structures, and treated wood boasts excellent features like rot, insect, and water resistance. Treated wood not only has a plain, natural appearance but also addresses the durability issue of regular wood, making it a suitable building material for custom log cabin construction. The变色茵 within the treated wood do not harm the cell wall tissue of the wood cells, but under suitable conditions, some变色茵 filaments can erode the cell walls, leading to a decrease in cellulose, hemicellulose, and hot water extractable content. Due to the reduction in cellulose and hemicellulose content in the wood cell walls, and the minimal breakdown of lignin and resinous substances, the relative content of lignin and resin slightly increases.
