1. Temperature dependency of rheological properites of different dispersions containing microfibrillated cellulose
Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)Sammanfattning : Today, the focus lies on the state of the environment and how we can choose more sustainable alternatives to oil based materials. One material of interest is microfibrillated cellulose (MFC). LÄS MER
2. CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE : CORRELATIONS BETWEEN PHYSICOCHEMICAL PROPERTIES IN MATERIALS COMPRISING MICROFIBRILLATED CELLULOSE
Master-uppsats, Umeå universitet/Kemiska institutionenSammanfattning : Microfibrillated cellulose (MFC) films have gained a lot of industrial interest lately dueto their good barrier properties and good mechanical strength. In this study it wasinvestigated whether rheological characteristics and conductivity of MFC dispersionscomprised of different MFC grades could be correlated to tensile properties of the MFCfilms produced from the corresponding MFC dispersion.

3. Ligninn i bindemedel för hållbara asfaltbeläggningar. Reologiska undersökningar
Master-uppsats, Lunds universitet/Trafik och vägSammanfattning : Bio-based binders have recently been introduced to reduce the dependence on fossil raw materials, which bitumen is produced of. Measurements with dynamic shear rheometer (DSR) and rotational viscometer (RVB) were performed on mixtures with bitumen and two different types of bio-based binders, namely Lignin 1 and Lignin 2.

4. Method development for rheological characterization of microfibrillated cellulose
Master-uppsats, Karlstads universitetSammanfattning : This thesis contributes to a development of a method for rheological characterization of microfibrillated cellulose. The intended use of the method is to be able to distinguish between different grades of microfibrillated cellulose. LÄS MER
5. Undersökning av asfaltbruk modifierat med polymerer och fibrer
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och vägSammanfattning : Asfaltsbruk har stor påverkan på asfaltens egenskaper. Under senare tid har många stu- dier genomförts med syfte att utreda hur asfaltsbruk kan modifieras f ̈or att förbättra egenskaperna hos den slutgiltiga asfaltskroppen. LÄS MER
