柱面连续滑动加压木材表面密实工艺对密实效果的影响
Influence of wood surface continuous sliding compression in cylinder method on the effect of densification
摘要
Abstract
Wood surface was densified by continuous sliding compression in cylinder method, density distribution, surface hardness and abrasion resistance of surface densified specimen compressed by different process parameters were measured. The results showed that: after compressed by continuous sliding compression in cylinder method, the densified layer was concentrated in the surface layer, and the larger the amount of compression, the larger the density of surface densified layer and the thicker surface densified layer, while the smaller the radius of the loading head, the larger the density of surface densified layer and the more concentrated on the surface the densified layer; the surface hardness and abrasion resistance increased with the increase of the amount of compression and the decrease of the radius of loading head; compared with the traditional flat pressing method, continuous sliding compression in cylinder method improved the surface hardness and abrasion resistance of wood, and greatly reduced the loss of wood volume. When using a loading head of radius 5 mm to compress 3 mm, the maximum density of the surface densified layer could reach 783 kg·m-3, which was 82.6％ higher than before, and surface hardness increased by 93％, with the volume loss rate of only 12％.关键词
