  1. 1. Colour Response in Drying of Nordic Hardwoods

    Författare :Stefan Stenudd; Thomas Thörnqvist; Timo Kärki; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beech; Betula pendula; birch; CIELAB; discolouration; drying; Fagus sylvatica; log storage; oak; press drying; wood colour; Quercus robur; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Colour and appearance of hardwood are of great importance for the interiorand furniture industry. The widespread use of transparent surface treatmentand a fashion that prescribe light colour on many species, means that deviationfrom the ideal have considerable impact on the industrial operations.

  3. 2. Industrial Wood Drying : Airflow Distribution, Internal Heat Exchange and Moisture Content as Input and Feedback to the Process

    Författare :Tommy Vikberg; Mihaela Campean; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

    Sammanfattning : At a sawmill, the most energy demanding process is the wood drying. The drying process also has a great impact on quality parameters determined for the boards in the final sorting and thereby affects the sales value to a great extent. LÄS MER

  4. 3. Wood colour related to kiln drying

    Författare :Bror Sundqvist; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood Physics; Träfysik;

    Sammanfattning : Raised temperature in artificial drying has led to some changes of wood products such as colour and strength etc. For special treatment of wood-products with clearly modified properties, among them colour, is often high temperature and steam used industrially. LÄS MER

  5. 4. On colour changes during kiln drying of hardwood : with special reference to beech and birch

    Författare :Stefan Stenudd; Linköpings universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Kiln drying is a key factor for the utilisation of our hardwood forest resources, providing our industry with high quality raw material. The increased use of transparent surface treatment in the furniture and carpentry industries during the last decades has put an increased focus on wood colour. LÄS MER

  7. 5. Internal Stresses in Wood Caused by Climate Variations

    Författare :Staffan Svensson; Avdelningen för Konstruktionsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction technology; climate variations.; sawn timber; kiln drying; mechano-sorption; hygro-mechanical; Wood; material testing; Anläggningsteknik;

    Sammanfattning : This thesis is the result of a series of investigations on the hygro-mechanical behaviour of clear wood in the radial and tangential directions. Approximately half of the effort put into the investigations was concentrated on laboratory tests while the remaining effort was concentrated on modelling the observations made in the tests. LÄS MER
