Abstract

The efficiency of using weakly basic cationic polyelectrolytes (BCP) depends on the sequence of introduction of chemicals (modified rosin product (MRP), electrolyte (E) and BCP) into fibrous suspensions and their content in dispersed systems. The hydrophobicity and strength of paper and cardboard were studied depending on three ways of using BCP: 1) MRP – E – BCP; 2) MRP – BCP – E; 3) BCP – MRP – E. The effect of BCP on the retention of components (fibers and sizing complexes) of paper masses was studied. It was found that the shift of the sizing process of fibrous suspensions (cellulose and waste paper) from the traditional mode of homocoagulation to a more effective mode of heteroadagulation contributes to an increase in the effectiveness of the use of BCP. It was found that the use of BCP according to methods 2 and 3 allows to obtain medium-glued types of paper and cardboard with high strength. Promising methods of using BCP are method 1, based on its additional participation in the new peptization process. It was found that the effectiveness of BCP (method 1) in cellulose and waste paper suspensions is high with a ratio of MRP : E : BCP equal to 1.0 : 0.8 : (0.025–0.030) and 1.0 : 1.2 : (0.030–0.045) respectively; paper and cardboard belong to the category of highly glued (have high hydrophobicity and they have improved durability. It was found that the use of BCP according to methods 2 and 3 makes it possible to obtain medium glued types of paper and cardboard with high strength.
