【摘要】 为了解氧等离子体处理对竹材表面性能的影响,用表面润湿角测定评估竹材表面润湿性,通过测试竹地板的胶层剪切强度了解竹材胶合性能的变化。结果表明:竹材经过氧等离子体处理后,表面润湿角有较大减小,尤其是带有竹青和竹黄的竹片,润湿角从原来的76.5°降到36.0°,同时胶合强度提高33%。更重要的是竹地板的胶合强度变异系数从原来的39.0%降到9.8%,对于无竹青和竹黄的竹地板尽管胶合强度没有明显增加,但变异系数有显著的降低。因此,竹材经氧等离子体处理后,表面特性改善,压制的竹地板质量稳定性提高。图3表4参11更多还原

【Abstract】 Bamboo strips were prepared and treated by O₂ plasma to study the effect of O₂ plasma treatment on bamboo surface performance.Wetting angle was tested to evaluate the wettability of bamboo surface before and after treatment.The results showed that the wetting angle reduced considerably after O₂ plasma treatment,especially for bamboo timbers with green coat and yellow endothecium,the wetting angle dropping dramatically from 76.5° to 36.0° and bonding strength of the flooring increasing by 33%.Furthermore,the coefficient variances（CV） of bonding strength between the testing bamboo floorings reduced from 39.0% to 9.8% after O₂ plasma treatment.Bonding strength of bamboo flooring without green coat and yellow endothecium didn’t improve a lot but CV decreased dramatically.Therefore,O₂ treatment improved not only the performance of bamboo surface but also the quality stability of bamboo flooring.更多还原
