|Title:||Paper And Surface Chemistry Part Ii - Coating And Printability [papel E Química De Superfície Parte Ii - Revestimento E Printabilidade]|
|Abstract:||Surface chemical interactions are important in many steps of paper manufacturing and converting. Interactions between fibres and colloidal particles, polymers, minerals and dyes are fundamental in papermaking, for example in floc formation, sizing and coating adhesion as well as in paper printability. Most papermaking interactions are complex and not very well understood, consequently, many paper formulations are designed according to an empirical trial-and-error approach. This work is a critical literature review of some interactions present in papermaking, coating and printing. In the first part of the review the interactions concerning the pulp fibres and other papermaking components in the wet-end were. In this second part the surface chemistry interactions present in coating formulation and printing are discussed. The surface engineering of paper and coating is also presented as a good potential for improving coating formulation, adhesion and paper printability. The knowledge of surface chemical interactions can be useful, not only for patents and product development, but also for improving in troubleshooting and customers support.|
