16. Near Wall Studies of Pulp Suspension Flow
Sammanfattning : .... LÄS MER
17. Modification of fluff pulp fibres: Cross-linking and alkali extraction
Sammanfattning : Fluff pulp has been one of the key components of hygienic products, such as diapers, for many years. Fluff pulp is dry defibrated and air-laid into the absorption core of diapers. The introduction of superabsorbent polymers (SAPs) in the 1980s decreased the dependence on fluff pulp, as the SAPs became the main absorbing material. LÄS MER
18. Design of Cellulose-Based Electrically Conductive Composites: Fundamentals, Modifications, and Scale-up
Sammanfattning : Modern demand for consumer electronics is fueling the generation of 'E-waste.' Furthermore, theraw materials and manufacturing methods used in the fabrication of electronics are not sustainable. LÄS MER
19. Tailoring adhesion and wetting properties of cellulose fibers and model surfaces
Sammanfattning : The layer-by-layer (LbL) technique was used to modify the surface of cellulose fibers by consecutive adsorption of poly(allylamine hydrochloride) (PAH) and poly(acrylic acid) (PAA) followed by a final adsorbed layer of anionic paraffin wax colloids. Paper hand sheets made from the modified fibers were found to be highly hydrophobic with a contact angle of 150°. LÄS MER
20. Turbulence measurements in fiber suspension flows : experimental methods and results
Sammanfattning : Turbulent mixing is present in many pulp and paper processes. It is a particularly important factor in the design and improvements of the paper machine headbox, influencing the final paper structure. LÄS MER
