Abstract
Se describe un sistema acuoso que contiene sales formadoras de incrustacion que incluye tanto carbonato de calcio como fosfato de calcio, caracterizado por un alto pH y altas concentraciones de calcita, que además contiene una cantidad efectiva sinergística de una combinacion que comprende (A) un fosfonato de poliéter-poliamino-metileno, (B) un terpolímero que comprende los monomeros de ácido acrílico, éter sulfofenometalílico y ácido maleico, y (C) un ácido hidroxifosfonoacético. También se provee un método para inhibir la formacion, deposicion y adherencia de tales sales formadoras de incrustacion en el sistema acuoso, empleando la combinacion sinergística.
