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 dewatering aid by coating at least some of the filler particles with a material that prevents the filler materials form adhering to dewatering aids. The dewatering aid holds the paper fibers together tightly and is not wasted on the filler particles. |
