Özet:

 Aim of study: The main aim of the study was investigating of different cationic polymers retention and drainage performances with pure PC and oxidized cellulose OC1, OC2 by using precipitated calcium carbonate PCC. Material and method: Cationic polymers were added to the cellulose-PCC suspension at three dosage ratios 1 mgg, 3 mgg, and 5 mgg. After mixing for 6 minutes., samples were withdrawn by using a syringe and a retention test was performed by colorimetric titration.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.

 Çalışmanın amacı: Bu çalışmanın temel amacı, farklı katyonik polimerlerin çöktürülmüş kalsiyum karbonat ÇKK kullanılarak saf selüloz ve okside selüloz ile retansiyon ve drenaj performanslarının belirlenmesidir. Materyal ve yöntem: Katyonik polimerler selüloz-ÇKK süspansiyonuna üç miktarda 1 mgg, 3 mgg, and 5 mgg ilave edilmiştir. 6 dakika karıştırma işlemi sonrası, süspansiyondan şırınga ile örnek alınmış ve retansiyon testi kolorimetrik titrasyon ile gerçekleştirilmiştir. Drenaj testleri için drenaj süresi Schopper Riegler cihazı kullanılarak, test kağıtlarının üretimi ise Rapid Köthen Kağıt Makinesi kullanılarak gerçekleştirilmiştir. Temel sonuçlar: Katyonik poliakrilamit hem saf selüloz hemde modifiye selülozlar için tüm katyonik polimerlerden daha yüksek retansiyon sağlamıştır. Drenaj performansları, başta Polietilenimin olmak üzere tüm polimeler ile hem saf selüloz hemde okside selülozlarda artış göstermiştir. Araştırma vurguları: Selüloza saf ve okside katyonik polimer ilavesi sistem retansiyonunu net bir şekilde arttırmış, drenaj performanları da pozitif yönde etkilenmiştir. Kağıtların ıslak sağlamlığı, kuru sağlamlık ile kıyaslandığında ciddi oranda artış göstermiş olup bu durum, oksidasyon prosesi sırasında oluşan yüksek oranda hidrofilik özelliğe sahip karboksil gruplarından kaynaklanmaktadır.
