  1. 1. Characterisation of thermally modified wood for use as component in biobased building materials

    Författare :Susanna Källbom; Magnus Wålinder; Dennis Jones; Kristiina Lillqvist; Kristoffer Segerholm; Marko Petrič; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Thermally modified wood TMW components; surface properties; inverse gas chromatography IGC ; water sorption; dynamic vapour sorption DVS ; Civil and Architectural Engineering; Byggvetenskap;

    Sammanfattning : The building sector shows growing interest in biobased building materials. Wood components, here defined as ground or milled wood, i.e. by-products (residuals/residues) from wood processing, such as sawdust or shavings, are valuable raw materials for new types of durable biocomposites suitable for outdoor building applications.

    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermally modified wood; Norway spruce; inverse gas chromatography IGC ; dynamic vapour sorption DVS ; X-ray photoelectron spectroscopy XPS ; surface energy; Värmebehandlat trä; gran; omvänd gaskromatografi IGC ; dynamic vapour sorption DVS ; röntgenelektronspektroskopi XPS ; ytegenskaper; ytenergi;

    Sammanfattning : Today there is growing interest within the construction sector to increase the proportion of biobased building materials made from renewable resources. By-products or residuals from wood processing could in this case be valuable resources for manufacturing new types of biocomposites. LÄS MER

  3. 3. Colour – A Reliable Quality-Control Tool for Industrial Thermowood® Production

    Författare :Petteri Torniainen; Dennis Jones; Olov Karlsson; Dick Sandberg; Henrik Veikko Juhani Heräjärvi; Luleå tekniska universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Thermally-modified timber; Thermo-S; Thermo-D; colour Lab; Scots pine; Pinus sylvestris; Norway spruce; Picea abies; quality control; Träteknik; Wood Science and Engineering;

    Sammanfattning : The objective of the work presented in this doctoral thesis has been to correlate the commercial output of  ThermoWood® process with a pre-defined, quantifiable, non-destructive measurable parameter - colour, and to show the feasibility of measurements to be the essential part of the internal and external quality-control system. Colour is the most evident property changed of thermally-modified timber (TMT). LÄS MER
