In 2007, a presentation at APPITA (technical association serving the Australian and New Zealand Pulp and Paper Industry) 60th anniversary conference in Gold Coast, Australia expressed how using online porosity measurements could lead to quick information resulting in better quality and runnability. Since then, nearly 200 units have been installed, looking at applications like these.
These are all relationships that are evaluated on laboratory equipment, however, having this information real-time, allows for quicker adjustments and fewer rejects.
Again, seeing the information faster, allows for adjustments to the process and better overall quality and runnability.
In the coating or application of OBA, a less porous sheet gives more "hold-out", meaning that a high percentage of the coating or OBA remains on the surface rather than penetrating below the surface pores. This results in better surface and optical properties for a given coat-weight or OBA-weight application.
