| 摘 要： | 为了合理开发利用紫椴小径材,对其材性进行了研究,进而解决干燥工艺,提高干燥质量。通过研究小径材的构造和物理力学性能,并和成材作比较,研制高温干燥基准,提高紫椴小径材的干燥合格率。一、试材、试验设备及方法试材采自黑龙江省尚志县东北林业大学帽儿山林场,条件见表1。试验设备利用自行研制的间歇式电热真空干燥机,工艺试验共进行三次,每次均对试材进行质量统计,测试试材缺陷。选取5块试验板,3块含水率检验板,包括心材板、边材板、应力检验板各1块。检验板和试验板端头用铝箔纸封涂,检验板每4h称重一次。

| Abstract: | This paper studied on the structural and physical properties of Amur linden thinned lumber and compared with nature wood. The difference of haracteristics was analysesed, then high temperature drying scadule wasmade. The process of drying technology and the effect of high temperatureon the strength and shinkage properties was studied. |
