Course detail

Technology of polymer treatment

FCH-MCO_TZPAcad. year: 2018/2019

Basic therms and sorting of technologies of plastics and ruber industry. After general introduction to rheology of fluids (polymeric melts) follow separate precesses of polymer processing, namely injection moulding, extrusion, calandering, pressing, polymeric fiber production methods, etc.

Learning outcomes of the course unit

The subject of the lecture-course is given to apprise the students with several types of polymer processing in the relation to basic material properties. The target of course is a realtion between
processing – structure of polymer for particular types of proceeding a ability to define material requirement for given technology on engineer principle.
