Abstract

Et preparat som inneholder en anionisk organisk polymer, et polyfosfat og en organofosfonsyre, hvor disse tre komponen- ter i preparatet er til stede i en kombinert mengde som er synergistisk effektiv til kontroll av dannelse av uorganiske belegg i et vandig system. Det beskrives også en fremgangsmå- te for kontroll av dannelse av uorganiske belegg på overflater i et vandig system. Det vandige system bringes i kontakt med et preparat som omfatter en anionisk organisk polymer, et polyfosfat og en organofosfonsyre. Disse tre komponenter er til stede i en kombinert mengde som er synergistisk effektiv til å kontrollere dannelse av uorganiske belegg i det vandige system.A composition containing an anionic organic polymer, a polyphosphate and an organophosphonic acid, wherein these three components of the composition are present in a combined amount that is synergistically effective in controlling the formation of inorganic coatings in an aqueous system. Also described is a method for controlling the formation of inorganic coatings on surfaces in an aqueous system. The aqueous system is contacted with a composition comprising an anionic organic polymer, a polyphosphate and an organophosphonic acid. These three components are present in a combined amount that is synergistically effective in controlling the formation of inorganic coatings in the aqueous system.
