Learning outcomes
|
The course follows on from lectures on paper production technology, especially the part of the so-called paper testing industry. Students will practically test the operation of some technological procedures on a laboratory and semi-operational scale, they will also perform comprehensive analyzes of paper/cardboard/ on the department's available devices.
Subject is conceived as a laboratory and serves to knowledge acquisition and practice on pilot equipments. Student is able at the end of this final laboratory course to self-dependent work on diploma thesis.
