以脲醛树脂胶黏剂处理臭冷杉刨花并压制成平面托盘,对平面托盘的厚度膨胀率、支撑脚内结合强度及板面静曲强度进行了研究。 经过实验分析得出托盘最佳生产工艺参数为:施胶量 20% ,热压温度 150 ℃ ,热压时间 30 min;对应的托盘性能为:吸水厚度膨胀率(2 h)为 7. 34% ,支撑脚内结合强度为 0. 31 MPa,板面静曲强度为 24. 12 MPa。

Smelly fir wood shavings was processed by urea-formaldehyde (UF) resin adhesive and used to make flat tray. The expansion rate in thickness, foot internal bond strength, and surface static bending strength were studied. Experimental result showed that the best process parameters are sizing amount 20% , hot-pressing temperature 150 ℃ , hot pressing time 30 min; the corresponding performance are the absorbing water thickness expansion rate (2 h) 7. 34% , foot bonding strength 0. 31 MPa, surface static bending strength 24. 12 MPa.
