| 摘要:在对比分析接装纸印刷面和非印刷面表面结构及性能的基础上，通过动态接触角法和动态渗透法，分析了接装纸印刷面和非印刷面的表面润湿和渗透性能，系统研究了液体在接装纸两面上的动态渗透过程。结果表明，接装纸的两面差异性导致了印刷面和非印刷面液体润湿和渗透的差异，动态渗透曲线的3个特征参数（tmax、t95和Ab）可以表征不同来源接装纸的润湿和渗透性能。在0.5 s时，接装纸的非印刷面和印刷面接触角降低值的差值在8°以内，可以获得较好的上机适用性。 |
| Abstract:Based on the comparative analysis of the surface structure and properties of the printed and non-printed surfaces of tipping paper， the surface wettability and permeation properties of the printed and non-printed of the tipping paper were analyzed via dynamic contact angle method and dynamic permeability method. The dynamic permeation process of the liquid on both sides of tipping paper was systematically studied. The results showed that the difference between the two sides of the tipping paper led to the difference of liquid wetting and penetration between the printing and non-printing surfaces. The three characteristic parameters （tmax， t95 and Ab） of dynamic penetration curve could be used to characterize the wetting and penetration performance of the tipping paper from different sources. At 0.5 s， the difference between the decrease of contact angle between the non-printed side and the printed side of tipping paper was less than 8°， of which the better machine applicability could be obtained. |
