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.

摘要： A paper-making aid composition, as well as processes for increasing tensile strength in paper and paper-making processes are provided. The paper-making composition comprises an anionic dialdehyde-modified polyacrylamide and a polyamide polyamine-epichlorohydrin (“PAE”) resin present in the paper-making aid composition at a weight ratio of PAE resin to anionic dialdehyde-modified polyacrylamide of from about 5:1 to about 1:1.6. The processes utilize an anionic dialdehyde-modified polyacrylamide and PAE resin at certain ratios. The anionic dialdehyde-modified polyacrylamide and PAE resin may be added to the pulp slurry as a composition or separately.
