本文研究了花生壳刨花形态及两种不同胶黏剂(酚醛树脂和异氰酸酯胶黏剂)各浓度下所得花生壳板材物理力学性能的影响规律.实验中使用四种不同形态刨花和五种不同浓度胶黏剂所制得的板材,测试了吸水率和吸水厚度膨胀率等物理性能,及弹性模量,静曲强度和内结合强度等力学性能.结果显示:花生壳板的质量与刨花形态有极其显著的关系,尤其体现于弹性模量的力学测试中,而胶黏剂浓度和板材密度对花生壳板的性能影响不显著.在各项物理力学性能测试中,内结合强度是唯一一个接近并且超出欧洲标准EN312所设定的极限值0.24MPa.在后期的显微观察中,SEM电镜扫描显示花生壳含有许多薄碎片和孔隙组成的多层结构,ED...

　　In this study,the effect of geometry size of particles and two types of resin(Urea-formaldehyde and Polymeric diphenylmethane diisocyanate)with different content on some physical and mechanical properties of peanut hull particleboard were discussed.Panels were manufactured from four different categories particles and five different resin content were tested for selected physical(water absorption and thickness swelling)and mechanical properties(modulus of elasticity,modulus of rupture and internal bond).Results showed that the performance of...
