Abstract
PURPOSE: To prepare a composition having improved static and dynamic stability, by adding specific amounts of an alkali carbonate and a water-soluble organic high polymeric dispersing agent to a wet zeolite cake just obtained by the filtration.
CONSTITUTION: 0.2W10wt%, expressed in terms of anhydride and based on zeolite, alkali carbonate and 0.05W5wt%, expressed in terms of anhydride and based on the zeolite, water-soluble or water-dispersible organic high polymeric dispersing agent are added to a wet zeolite cake obtained by the filtration, and the resultant mixture is agitated under a strong shear. For a detergent builder, the zeolite having a CaO exchange ability ≥100mg/g based on the anhydride, and zeolite a alone or a combination of zeolites A with X and Y is used. As for the alkali carbonate, sodium carbonate is preferred and carboxymethyl cellulose or carboxymethylated starch is used as the organic high polymeric dispersing agent. The aqueous zeolite slurry has a high solid concentration of 30W50wt% based on the anhydride.
