摘要

为考察试件平衡处理的必要性及处理条件参数的影响,比较不同平衡处理条件对中密度纤维板（MDF）和刨花板（PB）抗弯性能的影响。结果表明,随着相对湿度增大和温度升高,试板的抗弯性能呈降低趋势;单因素方差分析和t检验分析显示,高湿或高温处理条件,对板材的抗弯性能有显著影响;而低湿或低温处理条件,对不同厚度规格的板材影响程度有所不同。

Abstract

Effects of conditioning equalization treatments on bending strength of wood-based panels were investigated by testing bending properties of medium density fiberboard（MDF） samples and particleboard（PB） samples under varied equalization conditions.Results showed that the bending strength of the samples decreased with increased temperatures and relative humidity（RH）.Either high temperature or high RH had significant effects on the bending properties.Both of low temperature and low RH had different effects on modulus of rupture（MOR） and modulus of elasticity（MOE） of the samples with various thicknesses by one way analysis of variance and t-test analysis.
