Cracking Causes and Improvement Methods of Carbonized Wood in Liupanshui, Guizhou

Because of its naturalness and comfort, carbonized wood is very suitable for use in the exterior landscape of the building. It is practical, natural and beautiful. But the wood will definitely crack. The reason for the cracking of the anticorrosive wood is that the wood will dry naturally in the atmosphere, the surface moisture will evaporate quickly, the moisture content will first be low, and the surface will begin to shrink. In fact, the moisture content of the inner layer is still very high, and no shrinkage occurs. In this way, the outer layer must shrink. If the inner layer does not shrink, internal stresses such as external tension and internal compression are generated. When the tensile stress exceeds the resistance of the wood, When the tensile strength is limited, the structure of the wood is damaged and cracks occur. The change of moisture content is the main reason for the cracking of wood. When the wood is used indoors, it has dried to the equilibrium moisture content and the moisture content in the room is relatively stable, so cracking will occur rarely. When the wood is used outdoors, it is greatly affected by the weather, especially in the south where the rain is abundant. If long-term rainy weather occurs immediately after exposure, the moisture content between the inside and the outside of the wood varies greatly and changes rapidly. This long-term cycle will accelerate the wood cracking. . In addition, large-sized wood is more likely to crack because it i
