Study Guide

Objectives

The aim of the course is to provide the skills for measuring the properties of pulp, paper board, paper and polymers and interpreting their results

After completing the course, the student
• can make appropriate measurements for different types of paper board and paper
• can use his/her knowledge of raw materials and manufacturing when interpreting the differences between different paper boards and papers in the measurement results.
• can find out what pulp and wood species the sample is
• can test pulps and thus evaluate the refining result
• can make laboratory sheets and test them
• can interpret the effect of refining and fillers on pulp and paper properties based on theory
• can work work in a group
• can perform and interpret mechanical tests on polymers
• can write a report.

Content

Refining and testing of pulps, fibre analysis, testing pulp properties, making laboratory sheets and testing them. Measurements of different paper and paper board types: basic characteristics, optical and strength characteristics, absorption characteristics and surface characteristics. Mechanical testing of polymers. Interpreting the results and reporting.

Prerequisites

Prerequisites: Either the course "Orientation to Forest Industry and Finnish Society" or "Biotuote- ja prosessitekniikan perusteet" or knowledge of paper making raw materials, basic processes and properties achieved in some other way. At the same time, you have to participate in the "Kartongin ja paperin valmistus" course.

Assessment criteria, satisfactory (1-2)

The student recognizes different paper board and paper grades, defines the most important properties of those, understand the basics of the factors affecting quality. The student manages the assigned tasks under supervision/assisted, can make slides of fibers, recognizes fiber and pulp types, manages product analysis and the measurements based on that for different paper board and paper grades, can make tables and figures of results and can make some conclusions based on those. The student can work in a group, takes responsibility for his/her own work.

Assessment criteria, good (3-4)

Students will be able to relate the results of their work to theory and prior learning and to interpret and report on the dependencies of measurement results. Students will be able to manage laboratory work with little supervision. Students will be able to follow agreed schedules. The student takes responsibility for his/her performance and is committed not only to his/her own activities but also to the activities of the group.

Assessment criteria, excellent (5)

The student is able to link the results of his/her work comprehensively and correctly to theory and previous learning. The student is able to interpret the dependencies of the measurement results and to report them in a way that the work becomes a complete and integrated whole. The student works well in the laboratory and remains available to help other students. The student is able to keep to the agreed timetable. The student is able to work in a responsible, flexible and constructive way.
