ObjectivesIn paper and board making, additives have traditionally been added to the pulp suspension before forming. More recently, spray coating of the additives has been developed, which gives such advantages as increased mechanical retention and be

Recent studies have shown that foam-assisted application of additives into a wet web has advantages over the conventional way of adding the chemicals into the pulp suspension before forming, e.g., increased mechanical retention as well as high dosage
