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 perform and interpret mechanical tests on polymers
• can work work in a group
• 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. 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 Paper and Paper Board Production course.

Assessment criteria, satisfactory (1-2)

Recognizes different paper board and paper grades, defines the most important properties of those, understand the basics of the factors affecting quality. 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. Can work in a group, takes responsibility for his/her own work.

Assessment criteria, good (3-4)

Explains the relations of paper board and paper properties, manufacturing processes and raw materials, compares different grades, structures things in relation to one another. Manages the assigned task quite independently, helps the others, makes a plan/plans before carrying out tasks.
Cooperate responsibly and is ready to develop his/her interaction skills. Takes responsibility and commits to the group activities in addition to his/her own work.

Assessment criteria, excellent (5)

Understands the entity of paper board and paper quality. Can search for diverse courses of action and solution alternatives, justify his/her choices and try new courses of action, assesses diverse solution alternatives, combines solution alternatives creatively or creates new ones. Can cooperate responsibly, flexibly and constructively, develops his/her own and the group's interaction, works responsibly and in a committed manner considering the community and field requirements and needs.
