| Abstract: |
| The effects of chemicals type， dosage， stirring speed and reaction time on drainage property (SRF) of a highly-filled specialty paper stock were studied. A preferred drainage aid system was first selected based upon the results from single factor experiments. The application conditions of the preferred drainage aid system were then optimized through experimental regression model with central composite design of response surface method. A mathematical model describing the relationship between SFR and the four factors mentioned above was established from experimental data. Subsequent verification indicated that the calculated SFR values from the mathematical model were in good agreement with the experimental values. Therefore， it could be concluded that the established model was of good use in predicting drainage property of the highly-filled stock under a chosen application conditions. |
