  1. 6. Studies on High Alumina Blast Furnace Slags

    Författare :Amitabh Shankar; Seshadri Seetharaman; Rob Boom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : In the present work, viscosities and sulphide capacities of high alumina blast furnace slags were investigated. The systems investigated were four component CaO-SiO2-MgO-Al2O3 quaternary system, CaO-SiO2-MgO-Al2O3-TiO2 and CaO-SiO2-MgO-Al2O3-CaF2 quinary systems. LÄS MER

  3. 7. On the production of polyethylene dielectrics and conductive polymer composite fibres

    Författare :Martin Strååt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polyethylene; carbon black; polypropylene; melt spinning; foaming; polystyrene; fibres; cables; carbon nanotubes; electrical properties;

    Sammanfattning : Foamed cable insulations and conductive polymer composite fibres are two applications in polymer processing where the electrical properties of a material may be altered significantly during processing. Their common denominator is that the outcome depends to a large degree on the flow behaviour of the polymer melt, in particular the melt extensional properties. LÄS MER

  4. 8. Foaming of Some Cellulose Derivatives - Initial Studies

    Författare :Kristina Karlsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; rheological characterisation; Foaming; hydroxypropyl methylcellulose HPMC ; scale-up production; ethyl hydroxyethyl cellulose EHEC ; hot-mould baking; cellulose derivatives; extrusion;

    Sammanfattning : Fossil-based polymeric foams, based on polymers such as polystyrene and polyurethane, are important and widely employed materials due to their good mechanical properties relative their low density, the low price and the possibility for large-scale production. There are however a few disadvantages with these foamed products. LÄS MER

  5. 9. Heat transfer in falling film evaporation of black liquor - Experiments and theory

    Författare :Miriam Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaporator; black liquor; falling film; kraft pulp mill; Heat transfer; evaporation; viscosity; correlations; experimental; non-Newtonian;

    Sammanfattning : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. LÄS MER

  7. 10. Foam Formation and Starch Gelatinization with Alpha-Crystalline Emulsifiers

    Författare :Gisela Richardson; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; image analysis.; rheology; microscopy; amylose-lipid complex; gelatinization; dynamical arrest; amylose; starch; sponge cake; foam; emulsifier; alpha-gel; physical state;

    Sammanfattning : In the baking industry, emulsifiers in the alpha-gel state are used for foam formation. This thesis focuses on some parts of the effects of the emulsifier: how the foam formation and foam stability are influenced by the physical state of the emulsifier, how emulsifiers change the gelatinization and gel formation of starch, and the impact that these factors may have in a true product such as a sponge cake.
