Hornification and Fiber Properties
The research topic is hornification of lignocellulosic materials, knowledge about which is highly relevant for production, recycling and resource efficiency for all paper and board materials, as well as new applications for forest-based raw materials.
Förhorning av träfibrer
Projektet går ut på att genom experimentella studier bygga upp en kunskap kring förhorning av komponenterna i träfibrer. Förhorning är ett fenomen där, i nuläget praktiskt sett irreversibla, processer i samband med torkning förändrar fibrernas svällning och flexibilitet och därmed bindningsförmåga. Bindningsförmågan till andra fibrer har stor inverkan på hur starka fibernätverk kan skapas och […]
Energy efficiency and modelling of vacuum dewatering in modern tissue machines
The project is a research coproduction between the research environment Pro2BE at Karlstad University, Valmet and Albany International about energy efficiency of tissue production. The project is aimed at acquiring deeper knowledge about tissue vacuum dewatering and at modelling vacuum dewatering during tissue production, both with a conventional tissue manufacturing method (DCT) and with Through […]
Biobased barriers on packaging substrates
The PhD project in chemical engineering will use wood-pulp fibres, modified cellulosic materials, dewatering and drying as well as computational fluid dynamics, mass transfer models, rheological characterization of complex fluids and renewable packaging solutions. The studies will involve experimental work as well as calculations and modelling of the barrier performance. The research focus of the […]
EXACT – Excellence in Advancing for a Circular Transition
The research school ‘EXACT- Excellence in Advancing for a Circular Transition’ combines bioeconomy with smart digitalization, in a collaboration between the two research groups Pro2BE and DAMI4.0 at Karlstad University. The Ph.D. students will develop energy-efficient digitalized production processes or products and high-quality bio-based materials. The aim of this research school is to contribute to […]
Characterization of paperboard for creasing and folding
To form a package with desired properties, paperboard is creased and folded. Creasing creates delamination cracks which during folding cause the plies to buckle and form a permanent corner. The delamination cracks facilitate folding but reduce the load-bearing capacity of the packaging. The processes must therefore be controlled. The result is affected both by the […]
Smuts, olje- och vattenavvisande träytor
Detta är ett Formasfinansierat projekt 2018-2022 som har en doktorand vid KTH i samarbete med RISE och nu med Karlstads universitet. Doktoranden Haiyan Yin licade i november 2020 och fortsätter till doktor. Hon har publicerat två arbeten hittills, ett i Materials and Design och ett i Holzforschung.
