Official Course Description
The paper industry is a special key industry that uses a special technology in which colloid chemical and macromolecular processes play the dominant role. In this first of two courses, students learn about basic chemical and mechanical processes by which paper fibres are produced. The students become familiar with acidic and alkaline pulping processes and their chemical reactions as well as with modern bleaching processes. On the material side, the students learn about cellulose, hemicelluloses and lignins together with the typical structure-property relationships for these polymers.
