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

摘要： The invention provides a method of producing paper with a higher proportion of mineral filler particles than is otherwise be possible without the expected loss in paper strength by preflocculating the filler particles. The method allows for the use of the greater amount of filler particles by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a strength additive. The strength additive holds the paper fibers together tightly and is not wasted on the filler particles.
摘要翻译：本发明提供了一种生产具有比其它方法更高比例的矿物填料颗粒的纸的方法，通过预填充填料颗粒不会造成纸强度的预期损失。该方法允许通过用防止填料材料粘附到强度添加剂的材料涂覆至少一些填料颗粒来使用更大量的填料颗粒。强度添加剂将纸纤维紧密地保持在一起，并且不会浪费在填料颗粒上。

摘要： A method of preparing a stable dispersion of flocculated filler particles for use in papermaking processes comprises sequential addition of a first flocculating agent to an aqueous dispersion of filler particles followed by shearing of the dispersion, followed by addition of a second flocculating agent to the dispersion and further shearing of the resultant filler flocs to the desired particle size resulting in shear resistant filler flocs with a defined and controllable size distribution. In addition, a neutralizing coagulant can be added to the dispersion to partially or completely neutralize the charge of the filler before the first flocculating agent is added
