1.The water adsorption mechanism of poplar wood changed after carbonization. With the increase of treatment temperature, the hygroscopicity of poplar wood decreases, the water content of poplar carbonized wood used at room temperature is always maintained at about 6%, Make it moisture-proof.
2.The carbonization of poplar wood in high temperature environment reduces the concentration of hydroxyl in the components of poplar wood, reduces the hygroscopic property and internal stress of poplar wood, so that the exchange ability of poplar wood and external water is significantly reduced, thus greatly reducing the deformation and cracking of poplar wood caused by water change in use.
3.Complex chemical reactions occurred in the carbonization process of poplar wood components, which changed some components of poplar wood, reduced the nutrients of wood decay bacteria, and inhibited the growth of fungi in poplar wood from this link of the food chain.
4.Poplar wood carbonization treatment for pure physical technology, in the process of poplar wood carbonization only involves temperature and water steam, do not add any chemical agents, did not add any foreign substances, so poplar carbonized wood is quite environmental protection and safety, is environmentally friendly materials.
5.The color of poplar carbonized wood is consistent inside and outside. Depending on the process, the color of poplar carbonized wood can vary from yellow to dark brown.
