为了给椴木百叶窗加工提供理论依据,以椴木为研究对象,对其解剖特征、密度、干缩率及关键力学性能等材性指标进行测试和分析,并与常见的百叶窗树种俄罗斯樟子松进行对比.实验结果表明,椴木纤维长度平均为1 389.74 μm,纤维宽度平均为26.30 μ.m,纤维长宽比为53.97,纤维长度、宽度、长宽比值小于俄罗斯樟子松;基本密度、气干密度和全干密度分别为0.42,0.52和0.49 g/cm3,气干和全干密度均大于俄罗斯樟子松;弦向、径向和体积的气干干缩率分别为6.11％,4.03％和10.59％;弦向、径向和体积的全干干缩率为8.08％,6.09％和13.79％,椴木气干和全干干缩率均大于俄罗斯樟子松;椴木的抗拉强度为103.65 MPa,抗...

Basswood (Tilia sp.) is a light, soft and very easily workable wood species that can be quickly and easily used to make lightweight wood products, not only for the larger-scale operations such as manufacturing of wood veneer, ply- wood, musical instruments and window shutters and blinds. This odorless and finely grained basswood has easily man- aged to find its place on the worldwide commercial market. In order to provide a theoretical basis for the processing of Tilia sp. shutters, in this study, the Tilia sp. was used as an example to investi...
