摘　　要：采用常压介质阻挡放电产生的冷等离子体对杨木单板进行改性处理,研究单板含水率、涂胶量和胶黏剂种类对杨木单板胶合特性的影响,结果表明:常压冷等离子体处理能显著地改善不同制板工艺条件下杨木胶合板的胶合强度,提高率可达15%～45%。含水率越低,等离子体处理后强化胶合强度的效果越好,并且对于UF、MUF、PF三种胶黏剂,常压冷等离子体处理均可在常规胶量下增强杨木单板的胶合强度,表明了常压等离子体处理可运用于工业化生产,并且是降低成本和甲醛释放量的一个有效方法。The bonding strength improvement of poplar veneers by atmospheric pressure dielectric barrier discharge（DBD） treatment was investigated in this paper.The effect of moisture content,glue consumption and types of adhesive on the bonding strength of plywood were evaluated.The results show that the treatment can improve the veneer bonding strength remarkably in different production processes.The improved rate of bonding strength range is 15%～45%.The bonding strength after treatment enhances significantly at lower moisture content. For the three kinds of adhesives：UF,MUF,and PF,the atmospheric pressure DBD treatment can improve the bonding strength in the regular resin content.Therefore,atmospheric pressure DBD treatment can be applied in industrial production to reduce production costs and formaldehyde emission.
