Effect of Flaking Parameters on the Quality of Yellow Birch OSB.

This study explored the key influencing factors during the flaking process of yellow birch (Betula arneghaniensis brittori) wood strands with the aim of achieving energy efficiency, improving utilization of wood resources and enhancing wood strand quality by optimizing parameters and flaking processes of the disc flaker. The impact of disc flake knife rake angle, clearance angle, knife projection, counter knife angle, wood temperature, flaking direction, and wood flaking height on the production process of yellow birch wood strands were discussed. Birch wood strand length distribution and tensile strength were evaluated as the indicators of wood strand flaking quality, while strand curl index and flaking energy consumption during the cutting process were used to evaluate the production control of high-quality yellow birch wood strands.The results showed that longitudinal flaking can obtain better wood strand quality, and increasing the wood temperature and counter knife angle can effectively improve it as well. However, the increase of counter knife tingle resulted in more energy consumption. This study was significant for guiding the flaking process of oriented strand board (OSB), improving the efficiency of wood resource utilization, and enhancing economic benefits.
