The penetration of wood preservatives is improved due to the compression effect! Achieving high-quality materials with excellent uniformity and no variation!
We have introduced a new technology that involves pressurizing and injecting wood preservatives into compressed wood. Each piece of wood that makes up the structure becomes a high-quality material with excellent uniformity and minimal variation. By compressing the wood, it has become possible to sufficiently penetrate wood preservatives into wood with a moisture content exceeding 70%. 【Comparison of Penetration of Preservatives】 ■ Pressurized injection treatment only: Moisture content 33%, Heartwood ratio 65%, Compression ratio 0% ■ Compressed processing treatment + Pressurized injection treatment: Moisture content 79%, Heartwood ratio 60%, Compression ratio 20% *For more details, please refer to the PDF document or feel free to contact us.
