  1. 1. The Use of Lignin Derivatives to Improve Selected Paper Properties

    University dissertation from Stockholm : KTH

    Author : Stefan Antonsson; KTH.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kraft lignin; black liquor; cross-flow filtration; lignin derivative; kraftliner; oxidative coupling; laccase; manganese; linseed oil; mechano-sorptive creep; kraftlignin; svartlut; tvärsflödesfiltrering; ligninderivat; kraftliner; oxidativ koppling; lackas; mangan; linolja; mekanosorptivt kryp; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : Ved består huvudsakligen av tre typer av polymerer, cellulosa, hemicellulosa och lignin. Lignin bildas i naturen genom enzymatiskt initierad oxidativ koppling av tre olika typer av fenylpropan-enheter. Dessa bygger genom olika kol-kol- och kol-syre-bindningar upp en amorf tredimensionell polymer. READ MORE

  2. 2. Coated Norway Spruce Influence of Wood Characteristics on Water Sorption and Coating Durability

    University dissertation from Växjö : Linnaeus University Press

    Author : Tinh Sjökvist; Linnéuniversitetet.; [2019]
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Heartwood; Sapwood; Wood extractives; Moisture content; Paint; Alkyd; Acrylic; Linseed oil; Calcimine paint; Mould; Fungi; Algae; Weathering; Forestry and Wood Technology; Skog och träteknik;

    Abstract : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. READ MORE

  3. 3. Physical and morphological aspects of linseed oil impregnated pine (Pinus Sylvestris)

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Tomas Olsson; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träfysik; Wood Physics;

    Abstract : This work has investigated the possibilities of increasing wood durability using environmentally friendly chemicals. The chemical used in this study was linseed oil. The study also investigated flow paths during impregnation in pine and spruce. READ MORE

  4. 4. Influence of the fatty acid pattern on the drying of linseed oils

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Cecilia Stenberg; KTH.; [2004]
    Keywords : ;

    Abstract : The interest in renewable resources due to environmentalfactors has increased the interest to use new VOC-free linseedoil qualities together with reactive diluents for coatingapplications. The drying of two linseed oils, oilAwith a high content (74,2 %) of linoleic acid (C18:2)and oilB, a more traditional linseed oil with a high amount(55,2-60,4 %) of linolenic acid (C18:3), was followed in orderto reveal how the structural variations of the oils fatty acidpattern and the addition of the fatty acid methyl ester of oilAas a reactive diluent (0, 20 40 wt%) can change thedrying performances of the oils and their final filmproperties.

  5. 5. Scots pine (Pinus sylvestris L.) sapwood modification by vinyl acetate-epoxidized plant oil copolymer

    University dissertation from Stockholm : Fiber- och polymerteknologi

    Author : Shengzhen Cai; Sveriges lantbruksuniversitet.; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : A new bio-based formulation consisting of plant oil and vinyl acetate was developed for wood modification aiming at improving some of the material’s properties. In–situ epoxidation of linseed oil (LO) and soybean oil (SO) was carried out at different times with purpose of preparing epoxidized oils with various epoxy content. READ MORE
