1. Reinforced Biodegradable Polymer Composite Material based on Japanese Washi Paper
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för kemi - ÅngströmSammanfattning : In this study, traditional Japanese washi paper was sandwiched with poly(butylene succinate)(PBS) in order to produce a paper-based composite material that can be biologically degraded. Specimens were prepared using a hot press, and the mechanical properties of the washi paperand the new composite material were investigated by tensile tests. LÄS MER
2. Svavelcirkulation i cementprocessen längs ugnslinje 7
Kandidat-uppsats, Uppsala universitet/Institutionen för kemi - ÅngströmSammanfattning : Cement is produced in three main steps: grinding of a mixture of raw materials, sintering of the raw meal to form clinker, and grinding and mixing of clinker, gypsum and additives to make cement. Slag from steel manufacturing can be used to replace some of the raw material, but since slag is a carrier of some unwanted compounds, problems arise. LÄS MER
