  1. 6. Extrusion processing of wood-based biocomposites

    Författare :Maiju Hietala; Kaarlo Niskanen; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Interest in biocomposite materials and their use in various applications has been growing steadily over the past 10-15 years. Increasing environmental awareness and lower material costs are the main driving forces for using renewable materials, such as wood and cellulose fibers, as reinforcement in polymer composites.

  3. 7. Reactive extrusion of wood-thermoplastic composites

    Författare :Göran Grubbström; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The interest in Wood-thermoplastic composites (WPCs) has increased during the last decades. WPCs are commonly used as building material for decking and railing because of its low need of maintenance. Wood is a renewable resource of good mechanical properties and this make wood fibers interesting to use as reinforcement in a thermoplastic composite. LÄS MER

  4. 8. Agro-Waste Derived Additives for Polylactide and Tapioca Starch

    Författare :Edwin Azwar; Minna Hakkarainen; Anna Wistrand; Christian Glandfils; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Agro-industrial waste; wood flour; rice bran; polylactide; starch; biomass; degradation; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    Sammanfattning : Development of materials from renewable resources is one of the big challenges facing our world. In this thesis agro-industrial waste derivatives were developed and evaluated as additives for two common renewable polymer matrices, polylactide (PLA) and starch. Two waste products, wood flour (WF) and rice bran (RB) were evaluated in different forms. LÄS MER

  5. 9. Efficiency of a wood-fired bakery oven - Improvement by Theoretical and Practical

    Författare :Fabiao Manhica; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flow pattern; temperature profile; airflow; CFD; Wood-fired bakery oven WFBO ; bread quality;

    Sammanfattning : Combustion of biomass in small-scale furnaces is widely used in many countries and in different applications. The technology used is often “fixed grate” combustion in small batch furnaces. LÄS MER

  7. 10. Large organic aerosols in a human exposure chamber : applications in occupational dermatology and lung medicine

    Författare :Lennart Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Aerosol; bakery dust; bronchoalveolar lavage; chamber design; dermal exposure; exposure chamber; inhalation; large organic aerosols; mannequin; neutralizer; particle size; pinewood dust; skin;

    Sammanfattning : Exposure to large organic aerosol particles may cause respiratory and skin reactions. The use of human exposure chambers offers possibilities for experimental exposure challenges carried out with patients, in research and for investigations of the effects of exposure on the skin and in the respiratory tract.
