  1. 16. 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

    Sammanfattning : Wood is a complex material and the mechanical properties are influencedby a number of structural parameters. The objective of this study has been toinvestigate the relationship between the structure and the mechanical propertiesof hardwood. Two levels were of special interest, viz. LÄS MER
