The experimental results indicated that the tea waste powder as an additive to uf resin could reduce its free formaldehyde content and reduce the formaldehyde emission of uf resin bonded plywood ; the tea waste powder with much less size was easily mixed with uf resin and acted much more effective ; the tea waste as an additive to uf resin in a proper amount did nut decrease the bond strength of plywood 实验结果表明，茶叶废料作为填料添加到脲醛树脂胶黏剂中，能够降低其游离甲醛含量以及其黏接胶合板的甲醛释放量；茶叶废料颗粒度越小，与脲醛树脂混合性越好，消除甲醛效果越显著；茶叶废料的适量加入不会降低胶合板胶合强度。
