| Abstract: |
| In this paper, the application of pre-flocculate of cationic starch (CS) and novel calcium silicate (FACS) as paper filler was studied. The study compared the influence of different CS adding processes on dynamic retention, drainage performance and paper properties. Experimental results showed that CS was a good chemical to pretreat FACS. Compared with common CS adding process, the furnish containing pre-flocculate of CS and FACS had a better drainability and retention. Strength of the resultant paper was improved obviously in a lower CS dosage, the pre-flocculated FACS was distributed uniformly around the fibers. |
