New Forming Concept in Wet End Optimization

摘要

1. Curved Flow Path encourages activity, and ensures turbulence in continuation 2. Minimal Drainage at NFC reduces loss of fiber and chemicals, and enhances formation 3. Ceramic insert prevents uneven wear and saves replacement costs 4. Water Is Reintroduced and turbulence is created without excessive jumping or vacuum effects 5. Hydrodynamic processes: 5.1 Shear - Movement of Internal flows at different velocities having a distinct and recognizable pattern 5.2 Turbulence - Internal movement of the fibers in the undrained fiber suspension 5.3 Drainage - Dewatering of the fiber suspension in order to produce a consolidated fiber mat 6. End Result is better fiber distribution, faster speed, increased paper quality, reduction of basis weight of paper, and more efficient machine operation using Less Energy.
