控制锯材变形的方法

Controlling Methods for Lumber Deformation

针对影响锯材变形的因素 ,从降低原木残余生长应力、对干缩湿胀和干缩应力的干燥工艺处理 ,到下锯法的合理选择 ,以及通过木材改性达到尺寸稳定等几方面进行了全面探讨 。

In accordance with the factors of affecting sawn lumber deformation, the methods of controlling lumber deformation have been discusses systematically. Such as reducing the residual growth stresses in logs, treating the swelling and shrinkage of wood by drying technology, selecting rational sawing methods as well adopting physical and chemical modification of wood for its dimension stability. It could contribute the reference basis toward enhancing the quality of lumber and wood products.
