Study on the Effect of Drying on Binder Z- Directional Distribution in Coated Paper
The main objective of this study was to investigate the effect of drying condition on the binder distribution and characterize the binder migration in the method of numerical and visual analysis by Scanning Electrical Microscopy (SEM), Atomic Force Microscopy (AFM), and Laser Scanning Confocal Microscope (LSCM). In this study, Rhodamine B was used to stain the binder and as the probe to characterize z-directional distribution of the binder using LSCM. The results implied that it was reliable and effective method using LSCM to characterize the z- directional distribution of binder and analyze the influence of dry condition on binder migration. It could be concluded that the dry temperature played an important effect on binder distribution in coated paper and high dry temperature accelerated binder migration to the coating surface, however low drying temperature made binder migrate towards the interior of base paper. Moderate drying is good to binder distribution and coating layer forming.
