摘要： The invention provides a method of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength and enhancing filler retention in a papermaking process. The method improves the efficiency of drainage aids or wet web strength aids or wet strength aid by coating at least some of the filler particles with a material that prevents the filler materials from adhering to those additives. The drainage additive or wet web strength additive or wet strength aid holds the cellulose fibers together tightly and is not wasted on the filler particles.

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. 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 cellulose fibers together tightly and is not wasted on the filler particles. The method is particularly effective when the filler particles are a PCC-GCC blend and when the GCC particles are coated with the adherence preventing coating.

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

摘要： The invention provides a method of recovering and recycling waste coating color from papermaking coating process for use as wet end filler. The inventive method overcomes many technical challenges inherent in using waste coating colors as wet end filler such as the coatings having fine pigments that hurts sheet strength more than regular filler, having strong anionic charge and tendency to disturb wet end chemistry, causing excessive foaming, and containing a large amount of hydrophobic binder particles that tend to agglomerate in the white water and deposit on papermaking equipment. The method involves mixing the coatings with fresh filler particles, adding de-foaming agent, adding cationic coagulant, then preflocculating the mixture. This process causes fresh filler particles, pigments and binders in waste coating color to agglomerate together and form stable flocs with defined particle size distribution. Moreover, using such agglomerate as wet end filler was found to improve sheet strength properties by taking advantage of the binding ability of the latex or binders contained in the waste coating color.
