| 摘 要： | 以强化木地板、中密度纤维板、高密度纤维板、浸渍胶膜纸饰面人造板等5类人造板为试材,研究标准、模拟夏季、模拟冬季等不同温湿度平衡处理条件对上述人造板内结合强度、吸水厚度膨胀率和表面结合强度值等理化性能检测指标结果的影响。结果表明,高温高湿平衡处理使人造板的力学强度增加,吸水厚度膨胀率降低;低温低湿平衡处理使人造板力学强度降低,吸水厚度膨胀率增加;不同平衡处理条件下强化木地板吸水厚度膨胀率差异较大;对饰面板表面结合强度的影响大于素板。

| Abstract: | Influence of 3 equalizing conditions(standard,high temperature and high relative humidity,low temperature and low relative humidity) on physical and mechanical properties of wood-based panels were studied in this paper.Five kinds of wood-based panels were chosen as test samples,including laminate flooring,medium density fiberboard,high density fiberboard and surface decorated wood-based panel with paper impregnated thermosetting resins.The tested properties were internal bond,thickness swelling rate and sur... |
