摘要： Methods of improving dewatering efficiency, increasing sheet wet web strength, increasing sheet wet strength, and enhancing filler retention in a papermaking process are disclosed. The methods improve the efficiency of drainage aids, wet web strength aids, and/or wet strength aids by coating at least some of the filler particles with a material that prevents the filler materials form adhering to a those additives.

摘要： An on-line control and reaction process for pH adjustment and a control device for automatically adjusting pH value are provided. The process includes mixing a first enhancer and a second enhancer, optionally after diluting the first enhancer and/or the second enhancer with water, to form a mixture, setting a base pH value (δ1) and a target pH value (δ2), and adding pH adjuster into the mixture via a pH control unit and mixing to obtain a product with the target pH value. The pH control unit adjusts the adding of the pH adjuster by measuring or inputting certain parameters.
