COMPOSITION AND METHOD FOR CONTROLLING SILICA AND WATER SOLUBLE SILICATE DEPOSITION

摘要

A method for the inhibition of silica and silicate deposits on the internal surfaces of a water system consisting of adding to the water system a composition comprised of a blend oftwo water soluble copolymers. The first copolymer contains repeat units of maleic or acrylic acids and a phosphinic acid, or salt forms thereof. The second copolymer contains repeat units of acrylic acid and allyl hydroxy propyl sulfonate ether, or salt forms thereof.
