Abstract

The invention is a phosphate-free and low sodium boiler water treatment medicament. The medicament comprises the following ingredients: poly-alkyl acrylate; polymaleic acid salt; poly epoxy butanedioic acid; benzyl compound; sodium salt; and water. This is a multifunctional phosphate-free boiler inside treatment agent containing all-organic polymers, powerful dispersants and auxiliaries and other compositions. Through the reaction steps of chelation, dispersion of the hard scale in boiler water, fouling prevention, prevention of potential corrosion caused by the total deposition of iron and copper and the like in a boiler tube compartment, the PH value of the boiler water is stablized, meanwhile the incurrence of corrosion problems in pipelines and valves is reduced, the treatment medicament can help to replace completely the use of sodium phosphate tribasic, to prevent entrainment and improve the steam quality. The critical salt content in the boiler is increased, the concentration of boiler water is facilitated and energy is saved.

Description

technical field [0001] The invention relates to a boiler water treatment agent, in particular to a phosphorus-free and low-sodium boiler water corrosion and scale inhibitor. Background technique [0002] Boilers are essential equipment in modern production. In recent years, the number of boiler manufacturing enterprises has been increasing year by year, and the growth rate is astonishing. The number of boilers used in coal-fired, chemical, thermal power and other industries is also increasing. , the inevitable result of urbanization. [0003] Various types of corrosion occur in boilers during operation and decommissioning. In general, boiler corrosion is divided into chemical corrosion and electrochemical corrosion. Among them, electrochemical corrosion is more common and more harmful in boiler corrosion. The feed water of the boiler is an electrolyte. In the case of uneven chemical composition, different organizational structure, uneven deformation and internal stress, ...
