摘要

研究了热机械致密化处理对五种硬木耐磨性的影响。测试的物种包括白蜡树（Fraxinus sp.）、山核桃树（Carya sp。最初对每个物种的10个试样进行耐磨性测试，然后对这些试样进行热机械致密化处理。致密化过程包括将加热的压板在一个表面上加热至176°C（350°F）的温度，并在6.9 MPa（1000 Psi）的压力下压制试样5分钟。然后对致密试样进行相同的磨损试验程序。所有数据均采用一般线性混合模型的程序，通过双向方差分析（ANOVA）进行统计分析。研究结果表明，在五种硬木中，致密山核桃的耐磨性最高。

Effect of Thermomechanical Densification Treatment on Abrasion Resistance of Five US Hardwoods

The effect of thermomechanical densification treatment on the abrasion resistance of five hardwood species were investigated in this study. The species tested include ash (Fraxinus sp.), hickory (Carya sp.), red oak (Quercus sp.), sweetgum (Liquidambar styraciflua), and white oak (Quercus sp.). The abrasion test was performed according to the American Society of Testing and Materials standards. Ten specimens from each species were initially tested for abrasion resistance, and those specimens were then put through a thermomechanical densification process. The densification process consisted of bringing the heated platen up to a temperature of 176°C (350°F) on one surface and pressing the specimens at 6.9 MPa (1,000 Psi) for a period of 5 minutes. The densified specimens were then subject to the same abrasion testing procedure. All data were statistically analyzed by two-way analysis of variance (ANOVA) with the procedure of general linear mixed models. The results of this study indicated that densified hickory had the highest abrasion resistance among the five hardwood species tested.

期刊介绍： Forest Products Journal (FPJ) is the source of information for industry leaders, researchers, teachers, students, and everyone interested in today''s forest products industry. The Forest Products Journal is well respected for publishing high-quality peer-reviewed technical research findings at the applied or practical level that reflect the current state of wood science and technology. Articles suitable as Technical Notes are brief notes (generally 1,200 words or less) that describe new or improved equipment or techniques; report on findings produced as by-products of major studies; or outline progress to date on long-term projects.
