一、前言提高干燥温度,加快单板干燥过程,缩短干燥时间,已成为当前提高单板干燥产量的一项重要措施。如以我们试验的厚度1.2毫米的椴木单板在四种不同温度下的干燥速度比较,按单板含水率从100％减到30％计算,350℃的分别比3000℃、250℃和150℃三种温度加快1.6、2.2和5倍,但是最适当的干燥温度,不能单凭加快干燥速度提高产量来确定,还必须考虑到高温对于单板物理力学性质和胶合强度的影响。为此,我们结合高 I. INTRODUCTION Increasing the drying temperature, accelerating the drying process and shortening the drying time have become an important measure to increase the dry output of the veneer. For example, the dry speed of basswood veneers 1.2 mm thick at four different temperatures was compared with the drying rate of veneers at 100% to 30% ℃ three kinds of temperature increased 1.6, 2.2 and 5 times, but the most appropriate drying temperature, can not simply speed up the drying rate to increase production to determine, must also consider the high temperature on the veneer physical and mechanical properties and bonding strength. To this end, we combine high
