竹集成材增湿处理技术研究

The Reserch of Moistening Treatment for Glued Laminated Bamboo

采用加压方式对刨切薄竹用集成材进行了增湿处理,分别以浸渍时间、浸渍方向、胶层层数为因素等进行了试验。结果表明：大竹板材增湿后含水率达28.8%-63%,小竹板材达50%-88%;竹板各面单位面积增重率为：端面〉径面〉弦面,且随长度增加逐渐减小;竹板增重率随胶层层数增加其增湿效果逐渐降低。

We used pressure to moistening treatment for glued laminated bamboo which producted sliced bamboo veneer.The impregnation time,impregnation direction,the number of glueline and so on were studied.The result showed that：（1）the moisture content of big bamboo panels were 28.8%-63% after impregnation.The small bamboo panels were up to 50%-88%.（2）Unit area rate of liveweight growth of each face of bamboo：cross section〉radial section〉tangential section,and gradually decreases with the length.（3）Liveweight growth rate of Glued laminated bamboo and the effect of moistening decreased with the the number of glueline increasing.
