2) It can reduce the corrosion of equipment and extend the service life of equipment;
3) The pH value of white water is high, no accumulation of aluminum sulfate, white water is easy to recycle, which is conducive to reducing drainage pollution;
4) High paper strength can save pulping power;
5) CaCO3 can be used as a filler to save fiber raw materials and reduce costs;
6) The cost of rubber compound is higher than that of rosin rubber, which will increase the cost. It should be offset by adding and filling, which is not conducive to the paper type without filling or filling less;
