1. Reduce the corrosion of equipment, prolong it’s service life;
2. Improve the strength of paper, prevent deterioration, extend the use and retention time;
3. The whiteness and opacity of calcium carbonate can be used as filler to improve the sofeness of paper, bulk and printing adaptability;
4. White water PH is high, no accumulation of sulfate, improve white water reuse rate, easy to achieve white water enclose recycle, reduce the pollution.
