| Abstract: |
| The increasing amount of Ca2+ will significantly affected the closing white water system. ACS is a kind of chemical agent prepared in our lab contains high carboxyl content and can shield the effect of Ca2+. The interaction between dosage of ACS and concentration of calcium ions in pulp and its effect on properties of wet-end and paper sheets was analyzed mathematically. The results showed that the correlation coefficient between dosage of ACS and concentration of calcium ions in pulp was high. It approved the improvement of pulp and paper properties was due to the calcium ions controlling ability of ACS. In practice, for achieving the certain pulp and paper performances, the dosages of ACS needed to add into the pulp can be calculated based on the concentration of calcium ions in the pulp. It would be meaningful to realize white water circuit closing. |
