1. Improvement of the retention-fromation relationship using three-component retention aid systems
Sammanfattning : .... LÄS MER
2. Valuation of retention/formation relationships using a laboratory piot-paper machine
Sammanfattning : The interdependency between filler retention and paper formation is well-known, where a high retention is accompanied by impaired formation. A challenge for today’s papermakers is to increase the competitiveness for uncoated and coated fine paper, by improving the formation at the same level of retention. LÄS MER
3. Carbon Fibres and Carbonaceous Fillers in Engineering Thermosets
Sammanfattning : In view of the excellent properties of carbon fibres (CF) and the growing demand for multi-functional materials e.g., electrically conductive composites, engineering thermosets with carbon fibres are highly attractive. Similarly, electrically conductive fillers are of great importance. LÄS MER
4. On the Internal Sizing Mechanisms of Paper with AKD and ASA Related to Surface Chemistry, Wettability and Friction
Sammanfattning : Paper and board are hydrophobized (sized) to control the spreading and absorption of waterbased inks and retard the absorption and edge penetration of liquid packaging by aqueous liquids. Alkenyl ketene dimers (AKD) and alkenyl succinic anhydride (ASA) are synthetic sizing agents that are generally used under neutral or slightly alkaline papermaking conditions. LÄS MER
5. Materials Design for Paper Electrodes : A Papermaking Perspective on Electrode Fabrication
Sammanfattning : The electrification and digitalization of our society has propelled the demand for energy storage solutions. High-end technologies have been developed to satisfy the requirements of demanding applications, such as electromobility and portable consumer electronics, which also increasingly find markets for less demanding applications.
