Air Cushion Type Head Box For Paper Making Machine
The main function and objective of the headbox is to distribute a
suspension of stock evenly and uniformly on to the forming fabric.
This is the most important part of paper making .
The headbox 's (Operational parameters )will determine and
influence many of the important end paper properties like
formation,surface characteristics ,sheet stability and strength.
1,Head Box main tasks:
①Can effectively disperse fibers. The high-turbulence headbox can
produce high-intensity micro-turbulence, which can effectively
disperse fibers, prevent fiber precipitation and re-flocculation,
and can effectively improve the strength of the paper sheet.
②Distribute paper material evenly along the paper machine.
(Determine the horizontal quantitative distribution of the paper
web)
③The spraying is stable to ensure that the speed of the paste is
coordinated with the speed of the network. (Determine the
longitudinal quantitative distribution of the paper web)
