SODIUM WATER-GLASS SOLUTIONS WITH HIGH ORTHOPHOSPHATE CONTENTS FOR CORROSION PROTECTION IN THE FIELD OF DRINKING-WATER SUPPLIES

摘要

Proposed is a liquid aqueous concentrate in the form of a homogenous solution containing at least 8 % by wt. of silicate (calculated as SiO2) and at least 3 % by wt. of phosphate (calculated as PO4), as well as a method of protecting drinking-water pipes from corrosion using the concentrate.
