METHOD FOR PREVENTING SCALE AND CORROSION IN WATER SUPPLY AND HEATING SYSTEMS

摘要

FIELD: chemistry. ^ SUBSTANCE: invention relates to the methods for preventing the mineral scale and corrosion and can be used in water preparation of the heating, cooling systems and in the circulating water systems. The method is performed by adding the composition which contains the hexamethylene diamine tetramethylenephosphonic acid and its zinc containing complexonate at their mol ratio 4:1-2:1. ^ EFFECT: reagents and compositions withdrawal is reduced while efficiency of scale and corrosion preventing processing is increased. ^ 3 tbl, 3 ex
