本研究采用木材真空加压浸渍处理专用设备,较系统研究了浸渍压力和浸渍时间对杨木增重率的影响规律.结果表明:浸渍压力和时间对杨木增重率有很大影响;在本研究范围内,随着浸渍压力的提高和浸渍时间的延长,增重率呈现先快速增长后趋于平缓的变化趋势,增重率最高可达到36.6％;综合节约时间和能源成本的考虑,选定本试验的优化浸渍工艺为浸渍压力1.0MPa、浸渍时间2h。

　　The effect of impregnation pressure and time on the WPG of Poplar wood was investiganated by vacuum pressure impregnation treatment equipment.The results show that the effect of the impregnation pressure and time on the WPG are not significant.With the the increases in pressure and temperature, the WPG tends to increase sharply at first and then to grow gently, and it is up to 36.6%; Based on comprehensive consideration ofsavingtime and energy costs, We investigated the optimization of the impregnation pr...
