Content(s)
This work aims at using and applying to industrial cases the main fundamental notions related to the course "4FMT1061 : Physico-chimie des procédés papetiers" and to consolidate the knowledge about the addition of chemicals in the wet-end part of the papermaking process. The studied additives are mainly those used for improving the papermachine productivity and the end-use properties of the produced paper.
The apprentices study the additives used in their enterprise. The type of additives, their role, the involved mechanisms as well as their dosages and point of untroduction are precisely described in a written document and during an oral presentation.
Fundamentals must be clearly presented, the involved mechanisms must be described and well understood and the apprentices have to precisely explain why the additives are used.
Prerequisites- main physical and chemical properties of the pulps used in papermaking,
- physical and mechanical properties of papers and boards,
- Fundamentals in polymer chemistry and physical chemistry.
