资源简介：
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 natural gum and with a material that prevents the filler materials form 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.
