Coating Technology Laboratory Work (3cr)
Course unit code: PTK-IPPT7
General information
- Credits
- 3 cr
Objectives
The students know how to handle raw-materials, how to develop colour coating formulas, how to make colour coatings as well as how to coat and calender by using the laboratory equipment. The students know the significance of runnability parameters in the coating process. The students are able to measure the characteristics of the colour coating and paper and to interpret the results and how they affect the quality of the final product. The course strengthens the students’ professional development.
Content
Characteristics of paper and coated paper or paperboard. Rheological characteristics of colour coating and how they affect the result. Runnability of the coating. How the colour coating variables and calendering parameters affect the final product. Sheet coating using the coating machine.
