Advantages and disadvantages: because the production is made of solid wood with low density, such as fir, Tung wood, poplar, etc., the environmental protection is good, and the moisture content of joinery board is not high, between 10% - 13%. When the moisture evaporates, the board is easy to crack and deform. Poor grip force and large deformation coefficient. In the process of processing, less glue will be used, and the environmental protection performance is higher than that of ecological board and multi-layer board; the moisture-proof performance is far lower than that of particle board and multi-layer board; the stability of nail holding force is lower than that of particle board and multi-layer board. If the use environment is humid, it will cause great deformation, and the wood inside will become moldy and infested.
The third method of making "solid wood multilayer board" is generally to make the inner layer figure first, and then to make the single-sided or double-sided base plate by printing and etching method, and to be incorporated into the designated interlayer, and then to be heated, pressurized and bonded. The performance of multi-layer solid wood is much better. First of all, the thickness and layer sense of multi-layer solid wood base material should be considered. Good base material has uniform thickness, good layer sense, no cavity, overlapping phenomenon, flat and smooth surface, no bulge.
