Innehåll

Modules

The course is organised into seven modules, divided into theoretical and practical components to provide a comprehensive understanding of bio-based adhesives.

Theoretical Modules

Module 1: Introduction
- Overview of the field of bio-based adhesives, with a focus on developments in Sweden and Europe.
- Introduction to current challenges and opportunities in the wood products industry.

Module 2: Chemistry (Mandatory)
- Fundamental theories of adhesion and their application to bio-based adhesives.
- Classification of adhesives, including synthetic and bio-based alternatives.
- Exploration of bio-adhesives for various substrates such as wood, paper, and other natural materials.

Module 3: Performance (Mandatory)
- Key performance parameters of bio-adhesives, including bond strength, durability, and environmental resistance.
- Factors influencing adhesive performance, such as substrate type, curing conditions, and formulation.

Module 4: Applications (Mandatory)
- Industrial applications of bio-based adhesives in wood products and beyond.
- Overview of manufacturing processes, product requirements, and standards.
- Practical approaches to laboratory-scale manufacturing and evaluation of adhesive performance.

Practical Modules

Module 5: Synthesis (Mandatory)
- Synthesis of bio-based adhesives using laboratory-scale techniques.
- Understanding the preparation and formulation of adhesives tailored to specific applications.

Module 6: Analysis (Mandatory)
- Spectral and thermal analysis of bio-based adhesives (e.g. FTIR spectrosocpy, Thermogravimetric analysis (TGA) and Differential Scanning Calorimetery (DSC))
- Techniques for analysing adhesive properties, including viscosity, bond strength, and curing behaviour.
- Characterisation of adhesives to evaluate performance against industrial standards.

Module 7: Performance & Application (Mandatory)
- Laboratory manufacturing of wood-based panels using bio adhesives.
- Performance testing of wood panels, including mechanical tests and environmental durability assessments.

Examinationsformer

The course includes one assignment, which will be completed individually. The assignment involves writing a technical report. Reports can be submitted up to two weeks after the course ends. A pass/fail grading system will be used, and students that do not pass will have an opportunity to revise their work. Detailed instructions for the assignments are provided when the course is announced and the timing of each part is outlined in the course schedule.
