  1. 21. Non-wood fibers for strength enhancement of paper : Mixing softwood pulp with abaca, sisal and banana fibers

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Emilia Rinaldo; [2020]
    Keywords : non-wood fibers; abaca; sisal; banana fibers; paper strength;

    Abstract : The aim with this master thesis was to investigate the potential of using non-wood fibers to enhance the paper strength. Abaca, sisal and banana fibers were added to conventional bleached chemical softwood pulp. The effect of refining was investigated, both as co-refining and as separate refining. READ MORE

  3. 22. The impact of the pulping process on the properties of lignin nanoparticles

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Kristoffer Guthenberg; [2020]
    Keywords : Lignin; Nano; Nanoparticles; Extraction; Kraft; Organosolv; Softwood; Properties;

    Abstract : Lignin valorization is a key component of the total utilization of biomass in the biorefinery industry. Lignin has seen some use in several different applications, but a breakthrough is still yet to happen, and there is still a need to find more areas where lignin can be used as an alternative feedstock or as the main component.

  4. 23. Design of multilayer paperboard for optimisedcompression strength

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ali Salem Ali; [2020]
    Keywords : Compression strength; Paper; Cardboard; Dynamique Formette; Dynamic sheet former; SCT; Shortspan compression test; fibre; fibre properties; fiber; fiber properties; Multilayer;

    Abstract : This master thesis was issued by BillerudKorsnäs Gruvön. The focus of this thesis was theinvestigation of the effects different fibre types has on the compression strength of the wholepaper product. This stems from wanting to better understand how to produce a better paperboardconstruction with respect to stacking, storage, and transport. READ MORE

  5. 24. Non-uniformly distributed compression perpendicular to the grain in steel-CLT connections : Experimental and Numerical Analysis of bearing capacity and displacement behaviour

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Noah Ncube; Stephen Sabaa; [2019]
    Keywords : Compression; Perpendicular to the Grain; Cross-Laminated Timber CLT ; Connection; Non-uniformly distributed; Finite element; Load configuration factor;

    Abstract : Previous studies have mainly focused on the behaviour of timber under uniformly distributed compression perpendicular to the grain (CPG) loads. However, there are many practical applications in which timber is loaded by non-uniformly distributed CPG loads. READ MORE

  6. 25. Optimized utilization of raw materials for production of Cross Laminated Timber : Quality of laminations and its effects on mechanical properties of multi-layer panels

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Gustaf Lindstam; Beatrice Larsson; [2019]
    Keywords : ;

    Abstract : Cross laminated timber (CLT) is a product increasingly demanded by the market. This has led to an interest among producers to further optimize the use of raw material. READ MORE
