Its main tasks:
It can disperse fiber effectively. High turbulence headbox can produce high-intensity micro turbulence, effectively disperse fibers, prevent fiber precipitation and re flocculation, and effectively improve the strength of paper.
Evenly distribute the paper material horizontally along the paper machine. (determines the horizontal quantitative distribution of the web)
The shotcreting is stable to ensure the consistency between the slurry speed and the mesh speed. (determines the vertical quantitative distribution of the web)
