  1. 11. Influence of the adhesive on the mechanical properties in laminated multi-layer paperboard : Evaluation of two common dispersion adhesives, their failure modes, internal strength and influence on bending and tensile properties

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Anton Johansson; [2014]
    Nyckelord :Paperboard; adhesive; laminated;

    Sammanfattning : The objectives of the thesis were to investigate the adhesives influence on the mechanical properties in laminated multi-layer paperboard. The study also strived to find a method to investigate the interface strength of the adhesive layer. LÄS MER

  3. 12. Quantification of resin acids, fatty acids and sterols in process and waste water from forest industry

    Kandidat-uppsats, Avdelningen för kemi och biomedicinsk vetenskap

    Författare :Taner Ismailov; [2013]
    Nyckelord :effluent; waste water; forest industry; wood resin; wood extractives; resin acids; sterols; fatty acids; LLE; Liquid-liquid extraction; SPE; Solid phase extraction;

    Sammanfattning : This work focuses on wood extractives in effluents from the CTMP plant at Skoghall Mill. Pulp and paper industry effluents contain mostly natural compounds which are part of the trees. They are toxic to aquatic life but harmless in nature, as they are present in low concentrations.

  4. 13. Near Infrared Spectroscopy : An Introductory Study On Measurement Techniques And Tools For Analysing Moisture Content In Pulp And Paper Media

    Master-uppsats, Avdelningen för kemiteknik

    Författare :Niclas Dahlman; [2012]
    Nyckelord :NIR; spectroscopy; MVA; PLS; MSC;

    Sammanfattning : The growing technique of near infrared spectroscopy is used to build fundamental knowledge of how the method might be applied for moisture determination in pulp and paper media. Filter paper was used to investigate the angle and distance dependence, otherwise obscured by the uneven surface of pulp or dry fibers. LÄS MER

  5. 14. Energieffektivisering i ett reningsverk för skogsindustriellt avloppsvatten genom förfällning av extraktivämnen

    M1-uppsats, Fakulteten för teknik- och naturvetenskap

    Författare :Alexandra Rixen; [2011]
    Nyckelord :Energieffektivisering; avloppsvatten; ytaktiva ämnen;

    Sammanfattning : Pulp- and papermills expend vast amounts of water in order to produce pulp, paper and cardboard. Hence, they alsocreate vast amounts of waste water which has to be cleaned before it can be released into the receiving body of water. LÄS MER

  7. 15. Anaerob rening vid StoraEnso Skoghalls Bruk

    Magister-uppsats, Institutionen för ingenjörsvetenskap, fysik och matematik

    Författare :Mattias Aldaron; [2009]
    Nyckelord :wastewater treatment; anaerobic; aerobic; biogas; energy; toxicity;

    Sammanfattning : An analysis of a specific application of anaerobic wastewater treatment at a pulp and board mill, Stora Enso Skoghall, was carried out. A literature study was done and effluent wastewater from CTMP pulp production was analyzed. The analysis consisted of a broad constituent analysis and an anaerobic treatment trial. LÄS MER
