Preparation method of tracing type phosphorus-free corrosion and scale inhibitor

Abstract

The invention relates to a preparation method of a tracing type phosphorus-free corrosion and scale inhibitor. The preparation method is characterized in that the tracing type phosphorus-free corrosion and scale inhibitor comprises polyepoxysuccinic acid, a tracing type dirt dispersion agent, organic carboxylic acid sodium salt, a zinc salt, imidazolines, azoles and water, and is prepared by stirring, mixing and filtering the components. The tracing type phosphorus-free corrosion and scale inhibitor disclosed by the invention has the advantages of corrosion inhibition synergistic effect, low dosage, good stability, wide application scope and environment friendliness, and particularly due to the introduction of the tracing type dirt dispersion agent, an obvious synergistic effect is achieved, and the on-line detection on the medicament content is realized by detecting the fluorescence value, so that the problem that a general phosphorus-free medicament can not be detected or is difficult to detect can be solved.

Description

technical field [0001] The invention relates to the technical field of industrial water treatment, in particular to a preparation method of a tracer type non-phosphorus corrosion and scale inhibitor. It is a phosphorus-free, nitrogen-free, biodegradable corrosion and scale inhibitor suitable for industrial circulating cooling water systems, and capable of on-line monitoring and automatic dosing. Background technique [0002] During the recycling process of industrial cooling water, there will be different degrees of inorganic salt deposition, corrosion, bacteria and algae growth and other problems, resulting in serious consequences such as reduced efficiency of heat exchange equipment, blockage, corrosion and perforation, and bring great hidden dangers to industrial production. . The use of appropriate corrosion and scale inhibitors and supporting water treatment agents can reduce the adverse effects caused by corrosion, scaling, and bacterial growth of metal materials in e...

Problems solved by technology

[0007] The purpose of the present invention is to provide a tracer type non-phosphorus corrosion and scale inhibitor for industrial circulating cooling water system, which combines cathode and anode corrosion inhibitors, adsorption type and deposition type corrosion inhibitors, through each component The synergistic effect between them reduces the amount of each component, and through the use of tracer-type scale inhibitors and dispersants, it solves the problem that the non-phosphorus water treatment agent cannot be detected or is difficult to detect, and ensures the accuracy of the non-phosphorus water treatment agent. It avoids the threshold effect between some components, realizes the precise dosing of phosphorus-free water treatment agent in the circulating cooling water system, and ensures a good water treatment effect.
