SILICATE-POLYMERIC ALUMINUM SULPHATE AND PROCEDURE AND APPARATUS TO PRODUCE IT.

摘要

THE INVENTION REFERS TO BASIC POLYNUCLATE ALUMINUM SILICATE HYDROXY SULPHATE COMPOUNDS AND THEIR USE AND TO A PROCESS AND APPARATUS FOR THEIR PREPARATION. THE PROCESS CONSISTS FIRST OF MIXING AN ALKALINE METAL SILICATE AND AN ALKALINE METAL ALUMINATE SOLUTION AND OPTIONALLY A THIRD COMPONENT UNDER CONTINUOUS AGITATION TO FORM AN INTERMEDIATE ALCALINE SOLID INTERMEDIATE MATERIAL AND ADD SLOWLY ADDING THE INTERMEDIATE ALCALINE MIXTURE. UNDER HIGH CUT MIXING CONDITIONS.
