| 摘 要： | INTRODUCTIONIn papermaking industry, microparticle retention aid systems have been widely accepted in past decade because of their simultaneous improvements on retention and drainage but with no sacrifice in formation compared with conventional polymer retention systems. Polyacrylamide/bentonite is one of the typical microparticle retention aid systems,in which highly anionic charged bentonite is used as the microparticle component. The flocculation mechanism of this microparticle retentio…

| Abstract: | The various properties of bentonite samples with different sources and their synergistic retention effect with CPAM on wheat straw pulps were investigated. The investigated properties of bentonite included adsorptive capacity based on methylene blue, cation-exchange capacity, swelling volume, colloidal volume, particle size and charge properties. The results show that particle size is the most important properties of bentonite for its synergistic retention effect with CPAM. Using Wyoming type sodium bentonite without drying after modification can obtain the excellent furnishes retention. |
