摘　　要：通过正交试验法,探讨用豆渣苯酚液化树脂胶压制桦木三层胶合板的热压工艺,并对结果进行极差和方差分析,得到最优热压工艺参数:热压温度160℃、热压压力1.2MPa、热压时间5min、涂胶量240g/m2。在此工艺参数条件下压制的桦木胶合板,试板的胶合强度可满足GB/T9846—2004中Ⅰ类胶合板的要求。By orthogonal test, we studied the birch plywood hot-pressed with resin derived from liquefying soybean dregs in phenol and analyzed results by range analysis and variance analysis. The results showed that the optimal hot-pressing parameters were temperature of 145 °C, pressing pressure of 1.2 MPa, pressing time of 5 min, resin load of 240 g/m^2. Under this condition, the bonding strength of birch plywood meet the standard for class I plywood in GB/T 9846 - 2004.
