Coating Surface

The surface topography and properties of coating layer have an important influence on penetration and distribution of the print ink. In this research, the main objective was to investigate the effect of binder on the coating surface topography and characteristics. The surface microstructure was explored in the method of numerical and visual analysis using mercury porosimetry measurment and atomic force microscopy (AFM). The findings indicated that the binder content on the coating surface affected the pore size, depth and distribution of the coated paper surface. The conclusions were drawn that more amount of binder on the coating surface could contribute to improve the coating surface topography and the formation of even pore size and distribution, which was good to the paper surface characteristics and resulted in low roughness, high paper gloss, low ink absorption and high paper surface efficiency.

The surface topography and properties of coating layer have an important influence on penetration and distribution of the print ink. In this research, the main objective was to investigate the effect of binder migration on the coating surface microstructure. The surface microstructure was explored in the method of numerical and visual analysis using mercury porosimetry measurement, scanning electron microscopy (SEM) and atomic force microscopy (AFM). The findings indicated that the binder migration on the coating surface affected the pore size, depth and distribution of the coated paper surface. The little binder migration in the consolidation phase of coating color made a contribution to the forming of the coating layer, which made the coating surface more smother to printing performance.

The structure of the coating layer has a strong influence on the optical and physical properties of paper as well as on the print quality. Ink is transferred and sets onto the paper surface in the printing process, which affect printing quality and usage of ink. The objective of this experiment was to investigate the influence of calender on coating surface structure and Printability.

ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterized. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also performed on loose powder. Particle size distribution in a water powder suspension was determined with a laser particle size analyser. Compaction was performed on different pressures in a range from 100 to 400 MPa using the uniaxial double sided compaction technique without binder and lubricant. Micrographs of compacted specimens were obtained using scanning electron microscopy and atomic force microscopy. Pore size distribution was also determined by mercury porosimetry and nitrogen adsorption. Results revealed that with increasing pressure during compaction interagglomerate pores diminish in size until they reach some critical diameter related to the intra-agglomerate pore size.

AbstractThe aim of this study is to characterize the surface topography of aluminum nitride (AlN) epilayers prepared by magnetron sputtering using the surface statistical parameters, according to ISO 25178-2:2012. To understand the effect of temperature on the epilayer structure, the surface topography was investigated through atomic force microscopy (AFM). AFM data and analysis of surface statistical parameters indicated the dependence of morphology of the epilayers on their growth conditions. The surface statistical parameters provide important information about surface texture and are useful for manufacturers in developing AlN thin films with improved surface characteristics. These results are also important for understanding the nanoscale phenomena at the contacts between rough surfaces, such as the area of contact, the interfacial separation, and the adhesive and frictional properties.

Drying Condition

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.

The physical structure and chemical properties of coating layer have an important influence on transferring and setting of the printing ink. The typical objective of coating is to improve the appearance and printing properties of paper. In this study, the effect of drying condition on coating layer structure, surface properties, and print quality was investigated. The relationship between surface topography and drying condition was explored using scanning electron microscopy (SEM) and atomic force microscopy (AFM). The conclusions were drawn that high and low drying temperature were not good to the paper properties, which resulted in high roughness, low paper gloss, high ink absorption, low print gloss and paper surface efficiency. The findings indicated that the coating drying temperature affected the pore size, depth and distribution of the coated paper surface. Moderate temperature was benefit to pigment particles and binder arranging orderly, which made the coating surface had high smoothness, gloss, paper surface efficiency, and modest ink absorption.
