发明名称 A METHOD OF OPERATING A PAPERMAKING PROCESS
摘要 A method of operating a papermaking process containing a press section with at least one press nip is disclosed. The method comprises simultaneously performing the following steps: (a) providing a press media for said papermaking process that has a MFP size that is less than the MFP size of a press media that was originally supplied to said papermaking process; (b) adding an effective amount of one or more press sheet dewatering additives to said papermaking process prior to the last press nip of said papermaking process; (c) providing a sheet moisture ratio of a paper sheet entering a press nip of said press section to between about 2 to about 9; and (d) applying an optimum rate of pressure development at one or more press nips of said papermaking process, wherein said steps a, b, c, and d either: result in the production of a more uniform paper sheet without the reduction in paper solids exiting the press section that would be expected from performing a, c, and d, alone or in combination with one another; or result in the production of a more uniform paper sheet with an increase in solids content of said paper sheet exiting the press section.
