冷等离子体处理对竹材胶合性能的影响研究

摘要

[Objective] The paper was to study the effect of cold plasma on binding strength of bamboo. [Method] The bamboos were treated by 4 kinds of cold plasma nitrogen, oxygen, ammonia and argon, and the changes of contact angle and binding strength of bamboos before and after treatment were tested. [Result] Oxygen cold plasma treatment could increase binding strength of bamboo by 25%-30%. The cold plasma treatment was very fast and effective, but the changes of contact angle was not great in this experiment. [Conclusion] Cold plasma treatment could increase the binding strength of bamboo.%[目的]研究冷等离子体处理对竹材胶合性能的影响。[方法]采用氧气,氮气,氨气和氩气这四种冷等离子体分别对竹材进行处理,比较处理前后竹材接触角和胶合强度的变化。[结果]氧冷等离子体处理可提高竹材胶合强度25%-30%,冷等离子处理过程非常迅速且有效,但接触角变化并不大。[结论]冷等离子体处理导致木材胶合强度增加。
