Problems solved by technology

[0003] The technical problem to be solved by the present invention is: because water is often used in industry to cool large-scale machines and pipelines, but with the shortage of water resources, water resources need to be recycled. A small amount of insoluble salt in water is easy to deposit on the pipeline or machine to form inorganic salt scale, which will reduce the service life of the machine and reduce the heat transfer effect of the pipeline. Some natural polymers are often used in the prior art. Such as lignin and sodium humate to maintain the stability of water quality, but these polymers are easily degraded by microorganisms, and the scale inhibition effect is poor

Embodiment Construction

[0014] The present invention is a kind of composite antiscaling dispersant, and described dispersant is made of acrylic acid-acrylic acid ester-sulfonate copolymer, silicate, 1-hydroxyethylidene-1-1-diphosphonic acid, gluconic acid, benzene Paratriazole and water form, and wherein, the weight percent of each component is as follows:

[0015] Acrylic acid-acrylate-sulfonate copolymer: 20%~30%,

[0016] Silicate: 28% ~ 38%,

[0017] 1-Hydroxyethylene-1-1-diphosphonic acid: 10% to 15%,

[0018] Gluconic acid: 3% to 4%,

[0019] Benzotriazole: 1%-2%,

[0020] Water: 25% to 35%.

[0021] The object of the present invention is also to provide the method for using the composite antiscaling and dispersing agent. When used in the present invention, it can be compounded with zinc salt, and can also be compounded with zinc chloride to 8%-12%. The present invention It can also be used in combination with organic phosphonate scale and corrosion inhibitors. It can be used in the coolin...

Abstract

The invention provides a composite anti-scaling disperser, which comprises acroleic acid-acrylate-petroleum sulfonate copolymer, silicate, 1-hydroxyethylidene-1,1-diphosphonic acid, gluconic acid, benzotrizaole and water, the invention also provides the use of the composite anti-scaling disperser in industrial water treatment systems. The disperser can be compounded with zinc chloride to 8-12%, and the formulation of the invention can be charged by zinc salts for the treatment of low-medium hardness water, and to increase the inhibition rate of the formulation.

Description

Technical field: [0001] The invention relates to a chemical reagent for water treatment, in particular to a reagent used in an industrial circulating water system, in particular to a composite scale inhibitor and dispersant. Background technique: [0002] In industry, water is often used to cool large machines and pipelines. However, with the shortage of water resources, water resources need to be recycled. Because of the metal ions in the water, in the long-term high-temperature cycle, traces of insoluble salts in the water are easy to Deposited on the pipeline or machine to form inorganic salt scale, inorganic salt scale will reduce the service life of the machine and reduce the heat transfer effect of the pipeline. In the prior art, some natural polymers, such as lignin and sodium humate, are often used to Keep the water quality stable, but these polymers are easily degraded by microorganisms, and the scale inhibition effect is poor. Invention content: [0003] The tec...
