6. Influence of inhomogeneities on the tensile and compressive mechanical properties of paperboard
Sammanfattning : The in-plane properties of paperboard have always been of interest to paper scientists. Tensile properties are crucial when the board is fed through converting machines at high speeds. Compressive properties are essential in the later use. Inhomogeneities affect both the compressive and tensile properties. LÄS MER
7. Continuum modeling of the coupled transport of mass, energy, and momentum in paperboard
Sammanfattning : This thesis investigates the coupling between moisture, heat, and deformation in paperboard. The presented investigations are primarily conducted via macroscale continuum modeling but experimental characterisations are also made. LÄS MER
8. Influence of Polymeric Multilayer Treatment on Out-of Plane Properties of CTMP-Based Paperboard
Sammanfattning : .... LÄS MER
9. Optics of coated paperboard : Aspects of surface treatment on porous structures
Sammanfattning : Calendering of coated and uncoated paper is widely used to enhance optical properties such as gloss and print quality. The aim of this thesis is to characterize coatings and prints, and to validate models using experimental results from optical measurements of physical samples. Calendering of coated paper often leads to a brightness decrease. LÄS MER
10. Needle Punching of Wet Cellulose Fibre Structure
Sammanfattning : Needle punching of cellulose fibre structures was studied, in order to explore the possibility for a new method for bonding to be used in the paperboard industry. The interest in such subject was based on the need for stronger fibre-to-fibre bonding in the thickness direction of paperboard. LÄS MER
