Bijie anticorrosion wood manufacturers analyze the causes of cracking and the methods of improvement.
In real life, our living standard has been improved obviously. There are many Bijie antiseptic wood around us. It has a wide range of application. According to the understanding of Bijie antiseptic wood manufacturer, Bijie anticorrosive wood is suitable for building exterior landscape because of its natural and comfort. It is practical, natural and beautiful. But there will be a crack in the wood. The reason for the cracking of the anticorrosion wood is that the wood will be naturally dry in the atmosphere, the moisture of the exterior is rapidly evaporated, the moisture content will be low and the appearance begins to shrink. But in fact, the inner moisture content is very high, no shrinkage occurs, so that the outer layer should be shortened if the inner layer is not produced by shortening the external stress, internal pressure, tensile stress ultimate tensile strength than wood, wood arrangements would be destroyed, cracking.
The change of moisture content is the main reason for wood cracking. When wood is used indoors, because it has been dry to the equilibrium moisture content and the indoor water content is relatively stable, the cracking will be very few. When wood is used outdoors, it will be greatly affected by the weather. Especially in the south of the rainwater, if it is exposed to sunshine after a long time of rainy weather, it will accelerate the wood cracking if there is a big difference between the inside and outside moisture content of the wood and the change is fast. In addition, large scale wood is easier to crack, because the interior of large scale wood is more difficult and dry, and the anisotropy of dry shrinkage and swelling is more significant in large scale wood.
According to the reasons of wood cracking, the way to improve wood preservation in Bijie is to stick to the relative stability of wood moisture content and reduce the internal stress of wood, which is the way to reduce wood cracking. Because the outdoor use of wood environment is big, the water content of the environment can not be controlled, it can only reduce the practical touch of wood and water. Such as paint paint on the surface of wood, reduce the touch of wood and water; other waterproofing agents can be used to treat wood, reducing the water absorbability of wood. In addition, in a stable environment, it is boring for wood, slow releasing some internal stresses in wood and reducing cracking in a certain extent. Because wood is a natural biological data, each wood has its different properties, so it can not be completely consistent through the process. The properties of wood cracking and deformation are one of the inherent characteristics of the wood as a biological data.
