What is the yield rate of log processed into veneer
Processing log into veneer is an important link in the wood industry, and the yield is the key index to measure the efficiency of this process. The yield rate refers to the proportion of available materials obtained from logs, that is, the ratio of the amount of wood that can be used to make furniture or other wood products to the total weight of logs after processing.
Generally speaking, the yield of veneer processed from logs is between 40% and 60%, but this value is not fixed. It is affected by many factors. First, the variety of logs has a significant impact on the yield. For example, the yield of birch is high, while that of oak is relatively low. This is because different kinds of wood have differences in density, hardness, texture and other aspects, resulting in different losses in the processing process.
Processing mode and processing technology are also important factors affecting the yield. Although the yield of timber is high, the quality of timber may be poor; Although the yield of sawn timber is low, the quality of timber is good. In addition, the selection of cutting tools, the quality and size of logs, and the shape of logs will have an impact on the yield.
In practice, there are many ways to improve the yield. On the one hand, the yield can be improved by optimizing the cutting mode and tools, such as selecting the appropriate cutting angle and depth, and using efficient cutting tools. On the other hand, careful evaluation and classification of logs and selection of high-quality logs for processing can also effectively improve the yield.
It should be noted that increasing the yield does not mean sacrificing the quality of wood. In practice, the yield and wood quality should be taken into account to ensure that the processed veneer not only meets the use requirements, but also has good appearance and performance.
The yield of veneer from logs is a complex problem, which is affected by many factors. Through in-depth study and evaluation of these factors, and taking appropriate optimization measures, we can effectively improve the yield and realize the rational utilization and development of wood resources. At the same time, we should also pay attention to the wood quality to ensure that the veneer processed has good performance and appearance effect.
