Birch veneer factory will show you the knowledge of wood processing

It is said by birch veneer manufacturers that there will be many problems in the process of wood collection, processing and transportation. If the cutting technology is not appropriate, the wood will split, pull out the core and other phenomena, resulting in problems in the subsequent processing, and the value of the wood will be greatly reduced. In the process of processing, the discoloration of wood is also a very difficult problem, and it is not human factors, but the characteristics of wood itself. For example, when the red pine changes color, the heartwood will turn red brown, and the sapwood will turn yellow, which will affect the beauty of the finished wood.

Forest cutting is the basis of log collection, which determines the upper limit of the quality of the final product. Most of the forest resources are planted in rows. If the cutting sequence is not correct, there will be problems, resulting in damage to the wood. At the same time, the cutting technology for the trees also affects the quality of the wood. After collection, it is necessary to transport the felled wood. If the skidding method is not appropriate, it will also affect the processing quality, waste the forest resources, and is not conducive to the rational allocation of resources.

Through the identification and observation of the cross section, radial section and chord section of wood, we can fully understand the wood structure. However, many enterprises fail to deal with the problem of section identification in the process of wood processing, which leads to the deformation of even formed wood. Some of the finished products of small-diameter sawn timber processing enterprises have the problem of deformation during the placing process. Some birch veneer manufacturers think that the reason for this problem is that the wood drying measures are not in place, but the drying standard is up to the standard after testing.

The real reason is that the working procedure of small-diameter sawn timber is not properly matched, the processing methods of chord cutting and radial cutting are not unified, the selection of blank materials is not reasonable, the shrinkage and wet expansion of half chord cutting timber and radius cutting timber are different, resulting in local deformation. Therefore, it is better to designate professional personnel to identify and match the cutting materials, use different cutting methods for different cutting surfaces, and classify chord cutting materials, radial cutting materials, half chord cutting materials, radius cutting materials, etc. for the same product, the same cutting materials must be used for cutting, so as to ensure the quality of finished products.
