刨花板湿应力的研究

Study of Particleboard Wet Stress

刨花板在制造和使用过程 ,由于水分的变化而产生湿应力 .从研究结果可知 ,由湿效应引起的湿应力约为0 2 1MPa ,是平均界面结合强度降低值的 13 4% .定性和定量评价湿应力 。

Particleboard gives rise to wet stress in the course of manufacture and use owing to the change of moisture content. The result shows that the wet stress caused by wet effect is about 0.21 MPa, accounting for 13.4% of the average interface combination intensity reduction value. Qualitative and quantitative appraisal of wet stress is critically important to enhance the combination stability at interface.
