Laboratory Work (4 cr)

Objectives (course unit)

The students know how to analyse fibres, test pulp, beating, measuring pulps and the use of fillers. The students know how to make laboratory sheets and to test them. They are able to test the characteristics of paper and paperboard and to interpret the results. The students are able to work in teams and to write reports. The course strengthens the students’ professional development.

Content (course unit)

Beating and testing, fibre analysis, measuring pulp and fillers, making laboratory sheets and testing them. Measurements of different paper and paper board types: basic characteristics, optic and strength characteristics, absorption characteristics, surface characteristics. Interpreting the results.

Content scheduling

There are three laboratory works and those will be done as pair work and in the two-three persons groups. Two wider work, paper board and paper testing and the effect of refining will take place 5-6 weeks. The third work will take place one laboratory session. In the end of the course there will be sessions where reporting is guided. wk 37: Implementation plan, safety, plan, wk 38 - 41, 43 – 48: Refining and testing of pulp, fiber analysis, proportioning pulps and fillers, making paper sheet, testing paper properties, wk 49 – 51 Interpretation of the results and reporting, wk 51 Presentation of reports, feedback
