production process of papermaking additives

Papermaking Additives - Dulany - - Major Reference

2000-12-4  In papermaking, chemical additives can be characterized either as process additives or as functional additives. Process additives are materials that improve the operation of the paper machine and include retention, formation, and drainage aids; defoamers; wet‐web strength additives; pitch control agents; effluent treatment aids; slimicides and biocides; and creping aids.
