摘要
采用空气介质阻挡放电等离子体处理云南松单板表面,对处理后的单板进行胶合性能及表面性能分析,探讨放电等离子体处理单板表面的最佳工艺。结果表明:在1 000～4 000 W范围,随处理功率的增加,单板的胶合强度增大,水接触角减小,表面能增大;在处理功率5 000 W时,各指标变化趋势相反。当处理次数为1～7次时,随处理次数的增加,单板的胶合强度增大,水接触角减小,表面能增大;在处理9、11次时,各指标变化趋势相反。当放电等离子体处理功率为4 000 W,处理次数为7次时,木材表面改性效果最佳,其胶合强度、水接触角及表面能分别为2.1 MPa、43°、56.7 MJ/m2。
The best technology for Pinus yunnanensis veneer surface treatment with air dielectric barrier dis- charge plasma （DBDP） was studied by analyzing the gluing property and surface performance of the veneer after the treatment. The results showed that with the increase of processing power, the bonding strength of the veneer in- creased, the water contact angle reduced and the surface energy increased within the 1 000 - 4 000 W power range. Whereas the change tendency of each index became reverse when the treatment power reached 5 000 W. Within 1 - 7 times of treatment, when the treatment times increased, the bonding strength of veneer increased, but the wa- ter contact angle reduced and the surface energy increased. When the processing times were between 9 - 11, each index changed reversely. When the power was 4 000 W, and the veneer was treated for 7 times, the surface modifi- cation effect was the best, whose bonding strength, 2. 1 MPa, 43° and 56. 7 MJ/m2. surface water contact angle and surface energy was individually
