Abstract
The present invention relates to the technical fields of an industrial water treatment medicament and the preparation thereof. The present invention provides a water treatment medicament having a novel structure, a tracing function and a scale dispersion function. The polymer is prepared by that the synthesized polymer containing a phosphonic acid group, a carboxyl alkyl ester group, a carboxyl group and a sulfonic group, and fluorescent organic acid salt are added into a sealed container to be uniformly mixed and heated to 90 to 200 DEG C; the temperature is kept, and the materials are continuously stirred for 0.5 to 8 to carry out acid amide conversion reaction. The concentration of the product in water can be rapidly and accurately measured by fluorescent monitoring. Simultaneously, when various metal salt scale coexist, the present invention can ensure. A scale effect The synthetic technological method is simple and reliable and is easy to carry out industrialization control.
Description
The present invention relates to Treatment of Industrial Water medicament and manufacturing technology thereof.Exactly, relate to a kind of multipolymer and synthetic method thereof that has the novel texture of spike and scale inhibition dissemination concurrently; Be the resistance dispersion agent and the synthetic method thereof of tracer-containing.
The traditional analysis means of water treatment agent substantially all is that medicament is directly analyzed in the industrial circulating cooling water, and is generally all more loaded down with trivial details, and contained polymkeric substance is not still had accurate measuring method.Recent years, utilize the water treatment agent in the Measurement and analysis industrial circulating water fast of combining of Treatment of Industrial Water medicament and tracer agent.Existing patent major part all adopts the organism that will contain fluorescence and Treatment of Industrial Water with mixed with polymers together, joins in the industrial cycle water system, comes the content of monitoring polymer by the concentration of measurement fluorescent substance.As U.S. Pat 4783314, promptly be that water treatment agents such as 2-naphthene sulfonic acid (2-NSA) and polypropylene acid thing polyacrylamide are mixed, in the adding system, monitor by the mensuration fluorescence intensity.The flat 3-185341 of Japanese Patent then be with
Mix with polymer phase with water treatment, monitor by ultraviolet spectrometry.Though having satisfied, these patents analyze simple and efficient requirement, the problem of the direct measurement polymer content of failing fundamentally to solve.Japanese patent laid-open 5-163591 uses in the polymkeric substance in water treatment by chemical reaction, directly introduce the compound that shows fluorescence, therefore can measure the concentration of polymkeric substance itself easy, apace, but its used fluorescence compound is oil loving tagged compound monomer, in the water-soluble poly zoarium that the manufacturing water treatment is used, must in organic solvent, carry out carrying out the technology that solvent distills in the polymerization process, like this engineering not only numerous and diverse and also from the environment aspect, the aspect takes precautions against calamities, saving the resource aspect and consider, is not good method.
Purpose of the present invention proposes a kind of water treatment agent that has spike and scale inhibition dissemination concurrently with novel texture dirt dispersion agent and the synthetic method thereof of tracer-containing one by one exactly.Its concentration in the industrial cycle water system can be passed through the fluorescence monitoring rapid test, when multiple metal salt crust coexists, can guarantee scale inhibition effect simultaneously.The invention allows for synthetic method simple, reliable, that be easy to control.
