中密度纤维板内结合强度实验室间比对试验结果分析与评价

Analysis and Evaluation on Result of Inter-laboratory Comparisons of Internal Bond Strength of MDF

内结合强度是衡量非单板类木质人造板加工使用性能的一个重要指标。本文针对中密度纤维板内结合强度项目开展的实验室间比对活动,利用h值检验法和经典统计法对比对结果进行了综合的分析与评价,并对中密度纤维板内结合强度测定方法的具体操作提出一些建议。

The internal bond strength is one of the most important physical mechanical properties for non-veneer wood-based panels. In this article, the inter-laboratory comparisons between four laboratories of the internal bond strength of MDF were conducted and the results were analyzed and evaluated by applying the statistical methods of h test and classical statistic. In addition, suggestions on the specific operational method of MDF internal bond strength were proposed.
