    Sammanfattning : The European Green Deal 2020 goals for reducing emissions are enforcing rules on the energy performance of buildings. Therefore thermally insulating materials used as coatings are researched to reduce the energy emissions of buildings. An essential field of interest are nanomaterials. LÄS MER

  4. 3. Quartzene – A promising thermal insulator : Studies of thermal conductivity’s dependence of density and compression of Quartzene® in the form of powder.

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Erik Bamford; Gustav Ek; Daniel Hedbom; Johan Nyman; Victor Petterson; Josefin Sjöberg; Ida Styffe; Olivier Vizuete; [2014]
    Nyckelord :aerogel; insulation; conductivity; compression; Knudsen; Quartzene;

    Sammanfattning : The purpose of this project was to study Svenska Aerogel AB’s product Quartzene®, and develop its capacity as a thermal insulator. Quartzene® is a silica based mesoporous material developed by Svenska Aerogel AB, with properties similar to aerogels produced by the sol-gel process. LÄS MER
