Beschreibung
Zusammenfassung:	The present invention provides a method for preparing an active calcium silicate. The method comprises: mixing a lime milk, a fly ash desilicated liquid and a particle diameter control agent and reacting them, to obtain a active calcium silicate slurry. The particle diameter control agent is one of a pyrophosphoric acid salt, a metaphosphoric acid salt, a polyphosphoric acid salt, a polyacrylic acid ester, and a polyacrylic acid salt. The preparation method of the present invention can efficiently reduce large particles of the active calcium silicate, so as to reduce the influence of the large particles on papermaking process and paper quality.
