| 摘 要： | 采用碱液对马尾松单板进行脱脂处理,通过正交试验设计以脱脂率和抗拉率作为综合指标得出最佳的脱脂工艺,以期为马尾松单板的后续加工利用提供依据。结果表明:碱液脱脂能够有效降低马尾松单板中的脂含量,同时又不至于使单板强度降低太多;最佳的脱脂工艺为:药剂浓度0.5%,温度80℃,处理时间4 h,浴比为4。

| Abstract: | This paper adopted the alkaline liquor to handle Pinus Massoniana veneer,using orthogonal experiment design,taking defatted rate and tensile rate as composite index to obtain the best degreasing process,as a foundation of the subsequent process of Pinus Massoniana veneer.Results showed that: the alkaline liquor could effectively reduced the resin content of Pinus Massoniana veneer,and the same time the veneer intensity didn't decrease too much.The best degreasing process is: solution concentration 0.5%,temp... |
