| abstract | PROBLEM TO BE SOLVED: To reduce stains in a papermaking system in a paper manufacturing process even when the amount of a sizing agent added is increased. The present invention is a method for producing paper including a step of obtaining a pulp slurry and a step of making a pulp slurry, and the step of obtaining a pulp slurry is at least first in a dispersion containing pulp and water. A first chemical addition step of adding a water-soluble aluminum compound and a second chemical addition step of adding a second water-soluble aluminum compound and alkenyl anhydride succinic acid to a dispersion containing pulp and water are included in this order. The step of obtaining the slurry further includes a step of diluting with white water, and in the step of adding a second chemical, a mixture of a second water-soluble aluminum compound and alkenyl anhydride succinic acid is added to a dispersion containing pulp and water, or a second. The present invention relates to a method for producing paper, in which a water-soluble aluminum compound and alkenyl anhydride succinic acid are simultaneously added. [Selection diagram] None |
