    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.
