Do you know why antiseptic wood is cracked and deformed?
How is the dehiscence and deformation of the field anticorrosion wood? Why does the field anticorrosion wood crack and deform?
Bijie anticorrosive wood factory is mainly used in the field, and its purpose is only to enhance wood's ability to resist natural environment and biological invasion in the field. But in the process of application, it is unavoidable to attack the appearance of the dehiscence and deformation.
First of all, because of the natural characteristics of wood, it will inevitably cause the appearance of cracking and deformation. Therefore, whether wood is treated by antiseptic and impregnation, this situation will happen. Especially in the field of the field, the climate and environment change greatly. When the volume of water changes due to climate change and other factors, the volume will expand, and when the sun is shining, the volume of the wood will decrease. Therefore, wood will form deformation and craze and other forms, whether through preservation and disposal, during this long time of continuous expansion and decrease.
It is necessary for Bijie antiseptic wood to be treated by dry kiln before impregnation, because the moisture content of wood will prevent wood from absorbing and soaking and absorbing. In general, the moisture content of wood before impregnation is about 16-18%.
Because of the natural characteristics of the North European red pine raw material, its tree core layout is tight, it is difficult to be invaded by the outside world, and has natural anticorrosion. Because the heart of the tree can have the same life as the exterior, so the cracking does not affect the anticorrosion performance and the intensity of the layout.
Why does the two kilns do not solve the cracks in the wood?
The crack of the wood attack is divided into the origin of the change of the external water and the cause of the internal stress of the wood.
The cracking of Bijie anticorrosive wood has been effectively manipulated in the kiln dry disposal before the disposal of impregnated materials, but in fact, any kiln drying technology can only reduce cracking but not prevent splitting. But because in the field, it can not prevent cracking again. When the impregnated wood is exposed to sunlight, the drying speed of the wood will be faster, so it will form cracking and splitting. The key reason is that the outward transpiration speed of the wood is much faster than that of its interior.
