  2. 1. Precalendering and its interaction with other unit processes in the manufacturing of woodfree paper and board

    Author : Olof Steffner; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calendering; soft-nip calendering; wet press; compression; deformation; coating; water box;

    Abstract : ABSTRACTDuring calendering, which is done in order to improve its printing properties, the paper is compressed in one or more roll nips. Paper is a viscoelastic material and this will influence its performance during calendering. READ MORE

  4. 2. Thermoset polymers and coatings subjected to high compressive loads

    Author : Daniel Ståhlberg; Mats Johansson; Gijsbertus de With; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polymers; organic coating; thermoset; mechanical properties; compression; Surface engineering; Ytbehandlingsteknik;

    Abstract : This study describes the mechanical response of thermoset polymers under high compressive loads. The study is divided into two parts. The first part focuses on the behaviour of a powder coating when used in a clamping force joint and how the properties vary when the chemical and physical structure of the coating is changed.

  5. 3. Consolidation and structure of paper coating and fibre systems

    Author : Christian Kugge; KTH; []
    Keywords : coating colour; ground calcium carvonate; dlqy; dqboxymethylcellulose;

    Abstract : Paper coatings or coating colours are high solidssuspensions that are applied to paper to improve chieflyprintability and optical properties. A paper coatingsuspension, including pigments, binders and thickeners, is acomplex system which must be understood if the end-useproperties of paper are to be improved. READ MORE

  6. 4. Betulin-modified cellulosic textile fibers with improved water repellency, hydrophobicity and antibacterial properties

    Author : Tianxiao Huang; Monica Ek; Mats Johansson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Antibacterial; Betulin; Biorefinery; Cellulose; Grafting; Coating; Hydrophobicity; Textile; Water repellency; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Textiles made from natural sources, such as cotton and flax, have advantages over those made of synthetic fibers in terms of sustainability. Unlike major synthetic fibers that have a negative impact on the environment due to poor biodegradability, cotton cellulose is a renewable material. READ MORE

  7. 5. Preparation of Tablets from Reservoir Pellets with an Emphasis on the Compression Behaviour and Drug Release

    Author : Åsa Tunón; Göran Alderborn; Michael E. Aulton; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; multiple unit tablets; extrusion-spheronisation; barrier-coating; modified drug release; pellet types; compaction; tablet properties; deformation; densification; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : The preparation of multiple unit tablets was investigated in this thesis with the intention of gaining a deeper understanding of some of the factors that influence the properties of such tablets.Initially, three different types of pellets (drug, soft and disintegrant pellets) were combined as a model to investigate the ability of the mixture to form disintegrating tablets.
