摘要
本文测试了白桦材的ＰＨ值、酸碱缓冲容量，探讨了木材的酸碱特性对脲醛树脂胶固化时间的影响，确定了用脲醛树脂胶生产白桦材人造板时氯化铵等酸性固化剂的最佳加入量。
This paper studies that wood′s acid alkaline propertieseffect on the setting time of UF resin. pH date and acid alkaline bufferamount of birch was measured. The amount of acid setting agent into theUF resin which was used in the birch wood based panel was decided.
