Causes and solutions for deformation and cracking of anti-corrosion wood: The cause of deformation of the preservative wood (equivalent to ordinary wood) is the internal stress of the wood, which is caused by the change in the surface area of ​​the wood. The root cause of these changes is the excessive moisture inside the wood. The dried preservative wood is used outdoors and will be dried by wet. The wood is not malleable, so it is slowly dried from the surface of the wood to the core of the wood. When the surface is dried, the surface area will shrink. At this stage, the core of the wood is not dry, so the area of ​​the surface is reduced only by cracking to increase the surface area. To maintain the overall balance, resulting in cracking or deformation. 　 The only way is to carry out the shaping drying process to relieve the internal stress of the wood so that the internal moisture content of the preservative wood is ≤ 13 %. Steam kiln drying or vacuum kiln drying is an ideal treatment method. The basic principle is to give the wood a certain humidity (softening the wood surface) in the standard kiln, and to divide the moisture of the wood core with appropriate high temperature in time-sharing. Forced out. The substrate before the anti-corrosion treatment is dried to ensure the absorption of the active ingredients of the preservative, and to eliminate the stress inside the wood and improve the deformation and cracking of the wood; the wood after the anti-corrosion treatment is pressurized into the interior of the wood (total soaking), it needs to be dried twice (but it is air-dried, the active ingredient of the preservative is fixed inside the wood) to the moisture content ≤ 13 %, to eliminate the residual internal stress of the anti-corrosion wood again, stable size, maximum To the extent that it improves the deformation and cracking of preservative wood.
