Problems solved by technology

In the daily operation of central air-conditioning circulating cooling water and industrial circulating cooling water systems, inorganic salt scales are prone to occur, and the formation of inorganic salt scales will reduce the heat transfer effect of the water system
Most of the water treatment agents in the prior art are synthetic polymers. Although they are less toxic, they are not easily biodegradable and may soon face severe challenges from environmental restrictions.

Embodiment Construction

[0011] The present invention contains a scale inhibitor dispersant containing sulfonic acid copolymer, said scale inhibitor dispersant is composed of 2-acrylamide-2-methylpropanesulfonic acid copolymer, sodium lignosulfonate, tannin, humic acid Sodium and water form, and wherein, the weight percent of each component is as follows:

[0012] 2-acrylamide-2-methylpropanesulfonic acid copolymer: 35%~40%

[0013] Sodium lignosulfonate: 5% to 10%,

[0014] Tannin: 5% to 10%,

[0015] Sodium humate: 10% to 15%,

[0016] Water: 25% to 30%.

[0017] The purpose of the present invention is also to provide a method for using the scale inhibitor dispersant containing sulfonic acid copolymer. When used in the present invention, it can be used in combination with organic phosphonate and zinc salt, or it can be combined with zinc chloride Compound to 8%-12% use.

[0018] The invention is used for pre-membrane treatment and normal operation in chemical treatment, and can be used in combi...

Abstract

The invention provides an anti-scaling disperser, which comprises 2-acrylamide-2-methyl propanesulfonic acid copolymer, sodium lignosulfonate, tannic acid, sodium humate and water. 78{>The invention also provides a method for using the anti-scaling disperser by compounding with organic phosphate and zinc salts, or compounding with zinc chloride to 8-12%.

Description

Technical field: [0001] The invention relates to a chemical reagent for water treatment, in particular to a scale-inhibiting dispersant used in the daily operation of central air-conditioning circulating cooling water and industrial circulating cooling water systems, specifically a sulfonic acid-containing Copolymer antiscalant and dispersant. Background technique: [0002] Since environmental protection and sustainable development became my country's basic development strategy in 1995, the research and development of environmentally friendly water treatment agents has become one of the hot spots and important development directions of industrial water treatment research. During the daily operation of the central air-conditioning circulating cooling water and industrial circulating cooling water systems, inorganic salt scales are likely to be generated, and the formation of inorganic salt scales will reduce the heat transfer effect of the water system. Most of the water tre...
