Non-phosphorus type environment-friendly slow-release scaling inhibitor

Abstract

The invention discloses a non-phosphorus type environment-friendly slow-release scaling inhibitor which is prepared from the following components: tannin, polyacrylic acid, ammonium salt, D-erythorbic acid, silicate, a non-phosphorus polymeric corrosion inhibitor, a maleic acid-crylic acid copolymer, fatty alcohol-polyoxyethylene ether, zinc salt, a dispersing agent and deionized water. The non-phosphorus efficient slow-release scaling inhibitor with safe and environment-friendly components is provided, due to the reasonable design, all the substances in the formula can be prepared into the environment-friendly corrosion inhibitor with a good corrosion inhibition effect and high storage stability.

Description

technical field [0001] The invention relates to the water treatment industry, in particular, the invention relates to a phosphorus-free green and environment-friendly slow-release scale inhibitor. Background technique [0002] An antiscalant is a chemical agent that prevents scale from forming or inhibits its deposition and growth. At present, most of the cooling water treatment agents used in open systems are phosphorus-based formulas, but the discharge of phosphorus will cause eutrophication in the surrounding waters, promote the excessive reproduction of microorganisms, especially algae, and cause lake water splashes, seawater red tides and other hazards. Water is the basic condition for human survival, but water resources in the world are limited. my country's per capita water volume is only a quarter of the world's per capita water volume, and water resources are even poorer. With the rapid development of industry, the ecological balance of water has been seriously da...

However, during the use of cooling water, with the continuous circulation and concentration, the content of minerals in the water will continue to increase, which will aggravate the corrosion and scaling of pipes and equipment; in addition, many power plants now use reclaimed water as circulating cooling water Supplementary water, this kind of water has high content of inorganic salts and organic matter, which is easy for bacteria and algae to multiply, so it is necessary to add fungicides and corrosion and scale inhibitors to the cooling water to improve the quality of the cooling water, so as to ensure the safe operation of the equipment, but these chemicals will Increase the phosphorus content in circulating water, resulting in limited discharge. If it is placed in the environment, it will aggravate environmental pollution. At the same time, the addition of two chemicals will increase the cost of use
