  1. 6. 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

  3. 7. Rapid sintering of ceramics by intense thermal radiation

    Författare :Duan Li; Zhijian Shen; Lutz-Michael Berger; Stockholms universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering by intense thermal radiation; spark plasma sintering; heat transfer; mass transfer; scattering; coalescence; densification; grain growth; numerical simulation; porous ceramic; foaming; nanostructure; hierarchical heterogeneities; permeability; Materials Chemistry; materialkemi;

    Sammanfattning : Sintering is an important processing step for obtaining the necessary mechanical stability and rigidity of ceramic bulk materials. Both mass and heat transfer are essential in the sintering process. The importance of radiation heat transfer is significantly enhanced at high temperatures according to the well-known Stefan-Boltzmann’s law. LÄS MER

  7. 10. Interfacial Phenomena in Two-Phase systems: Emulsions and slag Foaming

    Författare :Abha Kapilashrami; Seshadri Seetharaman; Bridget Harris; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; film formation; o w emulsion; substrate effect; slag forming; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : In the present work studies were performed to provide understanding for further model development of the two-phase phenomena, film formation from o/w emulsions and slag foaming.The drying of o/w emulsions of different oil viscosities on hydrophobic and hydrophilic substrates was studied.
