Antiseptic wood under what circumstances deformation
Pinus sylvestris antisense wood has a large diameter and small diameter of the wood, small diameter wood short age, low strength, easier to use in the deformation cracking
China is now the most commonly used preservative wood raw materials are camphor pine, usually in the process of drying from the wet easily deformed, but the general anti-corrosion wood products as long as the installation of a month or so after the deformation, then the possibility of deformation later Big!
Antiseptic wood in the course of the use of surface cracking, internal cleft, split. Surface cracking is mainly due to the medium temperature is too high, low humidity caused by the reasons. In the case of high water content, outdoor use will inevitably occur cracking, deformation and other phenomena, which is inevitable. Antiseptic treatment can only ensure that the wood is not rotten in the outdoors, pest control, anti-fungal effect. The whole process of a kiln drying and natural drying can reduce the degree of cracking and deformation. However, the outdoor environment is a natural environment, the amount of deformation and cracks as long as it does not affect the overall feeling and function, but with the external environment more harmonious unity, the formation of a comfortable and natural intuitive feeling, such phenomena will not its anti- Structural strength.
Finally, for the effective way to prevent cracking deformation, can be used to prevent water permeability better preservatives, will certainly play a good effect. Therefore, for the use of harsh environments in the anti-corrosion wood, when the purchase of preservative wood, to choose a good anti-corrosion processing of the manufacturers of products.
The deformation of the wood is caused by internal pressure, and the cracking of the wood is due to the new changes in the surface of the wood, but the fundamental reason for the change is that the moisture content within the wood has changed.
