刨花板厚度及含水率对吸水厚度膨胀率的影响

Influence of Moisture Content and Thickness on Thickness Swelling for Particleboard

通过对4种厚度规格、5种含水率的刨花板与其吸水厚度膨胀率的关系进行研究,结果表明:刨花板的厚度越大,含水率越高,其吸水厚度膨胀率越小,板厚对吸水厚度膨胀率的影响大于含水率;对吸水厚度膨胀率与厚度、含水率建立了显著的二元线性回归方程,经过检测拟合度较高。

In this paper, the correlations between thickness swelling and moisture content/thickness of parti- cleboards with four kinds of thickness and five kinds of moisture content were studied. The results show that the thickness swelling reduces when thickness and moisture content of particleboard increase, and the thickness swelling of particleboard is influenced more by thickness than by moisture content. The significant two-dimen- sional linear regression equation of thickness swelling is built about moisture content and thickness, and the fit- ting degree is high after detection.
