| Özet |
Material and method: Cationic polymers were added to the cellulose-PCC suspension at three dosage ratios (1 mg/g, 3 mg/g, and 5 mg/g). After mixing for 6 minutes., samples were withdrawn by using a syringe and a retention test was performed by colorimetric titration. Drainage time was determined by using the Schopper Riegler apparatus for drainage tests, and test papers were prepared by the Rapid Köthen Paper Machine. Main results: Cationic polyacrylamide (CPAM) provided higher retention values than all polymeric substances for both modified cellulose and pure cellulose. Drainage performances were enhanced by the whole polymers, especially polyethyleneimine (PEI), with both PC and oxidized samples. Research highlights: Cationic polymer addition to celluloses (pure and oxidized) clearly increased the retention of the system, and also drainage performances were affected positively. The wet strength of papers was significantly enhanced compared to the dry strength, and this situation is a result of the highly hydrophilic nature of the carboxyl groups introduced during the oxidation process. |
