CHALLENGE OPTIMIZATION OF RETENTION, DRAINAGE, FORMATION AND SHEET-FORMATION IN PAPER INDUSTRY
Economical & efficient
Retention precisely coordinated: OPTIRET©
Water savings, higher speeds and new headbox models of ultra-modern paper machines place increased demands on retention aids.
With our advanced retention aids and systems from the OPTIRET© range, for different paper qualities from waste paper to graphic paper, you can achieve optimum performance and cost efficiency at the same time.
The expertise of our application specialists is your competitive advantage: only the interaction between the selection of the most suitable additive, the correct dosing point(s) and quantities guarantees the achievement of the sensitive balance of retention, drainage, sheet formation and formation in the machine circuit required for runnability and product quality.
Factors influencing retention
Filler and fines retention is a very complex process that is influenced by practically all process and stock parameters in the wet end of the machine:
- Material parameters
- Material composition and grinding degree
- Chemical parameters
- Retention agent type and quantity
- Dosing point
- Contaminant content
- Technical parameters
- Headbox
- Construction type of wet end
- Sieving speed and sieve structure
- Vacuum settings
- Foil angle
- Water flow and temperature
