1. Interfacial Adhesion Failure : Impact on print-coating surface defects
Sammanfattning : The aim of this work was to develop a solid knowledge on formulation effects controlling offset ink-paper coating adhesion and to identify key factors of the coating and printing process affecting it. Focus lay on comprehending the impact of pigment dispersant on ink-paper coating adhesion and ultimately on the print quality of offset prints. LÄS MER
2. Interactions between polymeric dispersants and colloidal ceramic surfaces
Sammanfattning : Increased use of environmentally acceptable chemicals and reduced energy consumption are two foreseeable demands within the ceramics industry. This will require the replacement of organic solvents and lowering of sintering temperatures. LÄS MER
3. Nonionic surfactants from kraft lignin
Sammanfattning : .... LÄS MER
4. Slurry rheology of industrial minerals and its effects on wet ultra-fine grinding
Sammanfattning : This thesis investigates slurry rheology of industrial minerals (limestone and quartzite) and its effects on wet ultra-fine grinding in order to reduce energy cost, increase the throughput as well as the product fineness. The influences of solid concentration, molecular weight of a dispersant, and particle size and distribution on the rheological behaviour of original limestone slurries have been investigated. LÄS MER
5. Slurry rheology of limestone and its effects on wet ultra-fine grinding
Sammanfattning : This thesis investigates rheology of limestone slurries and its effects on wet ultra-fine grinding in order to reduce energy cost and increase the throughput and the product fineness. The influences of solids concentration, molecular weight of a dispersant, particle size and distribution, and temperature on the rheological behaviours of limestone slurries have been investigated with rotational and cone-plate viscometers.
