  1. 6. Method development for rheological characterization of microfibrillated cellulose

    Master-uppsats, Karlstads universitet

    Författare :Elin Wahlkrantz; [2020]
    Nyckelord :microfibrillated cellulose; MFC; rheology; characterization; dynamic rotational rheometer; complex viscosity; amplitude sweep; dry content; pH; conductivity; measuring geometry; gel; mikrofibrillerad cellulosa; MFC; reologi; karakterisering; dynamisk rotationsreometer; komplex viskositet; amplitudsvep; torrhalt; pH; konduktivitet; mätgeometri; gel;

    Sammanfattning : 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

  3. 7. Predicting fillability of viscoelastic product in Tetra Recart

    Master-uppsats, Lunds universitet/Förpackningslogistik

    Författare :Nawapan Boonchum; Roxanne Mae V. Targa; [2020]
    Nyckelord :Meat batter; Filling machine; Rheology; Pressure drop; Non-Newtonian fluid; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : It is of interest to design a methodology in predicting the fillability of non-Newtonian viscoelastic product such as meat batter by analyzing its rheological properties, reducing the need to perform pilot plant scale tests. Meat batter with different added water produced in laboratory and pilot plant were analyzed to represent meat batters with different rheological characteristics and filling behaviour. LÄS MER

  4. 8. Vibrationer och engesvängningar i Alfdex separator

    M1-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Matilda Adolfsson; [2019]
    Nyckelord :vibrations;

    Sammanfattning : The purpose of this thesis is to create a greater understanding of what happens inAlfdex’s separator in terms of natural frequencies, also called resonances. Try in asystematic way to find out where the problem is and produce a possible solutionto the problem. LÄS MER

  5. 9. A rheological study of hyaluronan and sodium hydroxide at different concentrations

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Natalia Gentek; Melissa Jöe; Sofia Lindell; Karin Norgren; Ellen Sjövall; [2018]
    Nyckelord :hyaluronan; hyaluronic acid; sodium hydroxide; rheology; fluid; elastic modulus; loss modulus;

    Sammanfattning : This thesis examines how the rheological properties change depending on the composition of hyaluronan, HA and sodium hydroxide, NaOH. This was performed to see if there was any relationship between the rheological properties of a sample depending on different compositions of HA and NaOH. LÄS MER

  7. 10. Reologistudie av vattenbaserade industrifärger

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Fatima Abdirahman Ahmed; [2018]
    Nyckelord :Rinning; skjuvspänning; viskoelastisk; lagringsmodul; förlustmodul; reometer; rinnmotstånd;

    Sammanfattning : I detta examensarbete har reologiska egenskaper av färg studerats varav viskoelasticitet, rinning och utflytning har varit av huvudsakligt intresse. I denna studie presenteras metoder som förutser hur färg rinner vid industriell applicering med hjälp av data från reologisk mätningsutrustning. LÄS MER
