  2. 1. On Modelling and Estimation of Curl and Twist in Multi-Ply Paperboard

    Author : Gianantonio Bortolin; KTH; []
    Keywords : modelling; grey box; curl;

    Abstract : This thesis describes a grey-box model for the dimensionalstability properties (i.e. curl and twist) of the carton boardproduced at AssiDomän Frövi paper mill in Sweden.AssiDomän Frövi AB is one of Sweden major cartonboard manufacturer, and produces some 350000 ton of board peryear.

  4. 2. Beyond averages – some aspects of how to describe a heterogeneous material, mechanical pulp, on particle level

    Author : Olof Ferritsius; Birgitta A. Engberg; Per Engstrand; Mats Rundlöf; Øyvind Weiby Gregersen; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Visualisation; Uniformity; Distributions; Independent common factors; Weighted fibre length; Fibre bonding; Fibrillation; Curl; Wall thickness; Particle analyser characterisation; Raw material; CTMP; Process configuration; Sampling accuracy;

    Abstract : For a more profound understanding of how a process works, it is essential to have a relevant description of the material being processed. With this description, it will be easier to evaluate and control processes to produce more uniform products with the right properties. READ MORE

  5. 3. Residual stresses in paperboard and the influence of drying conditions

    Author : Magnus Östlund; Sören Östlund; Douglas Coffin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; paper; drying; mechanical properties; residual stress; curl;

    Abstract : The drying sequence in the manufacturing process for paperboard involves evaporation of water, primarily from within the fibres. The vapour is then transported out of the web by pressure or concentration gradients. READ MORE
