Circulating water treatment agent is a chemical agent used to treat and improve circulating water systems (such as cooling water, boiler water, industrial circulating water, etc.). They have multiple functions aimed at maintaining the quality of circulating water, preventing corrosion and blockage of pipelines and equipment, and improving the efficiency and reliability of the system. The following are the main functions of circulating water treatment agents:
Corrosion inhibition: Metal components (such as steel) in circulating water are susceptible to corrosion. The corrosion inhibitor in the circulating water treatment agent can form a protective film that covers the metal surface, reducing direct contact between the metal and water, thereby reducing the rate of corrosion.
Anti scaling and cleaning: Hard water salts (such as calcium, magnesium, etc.) that may exist in circulating water will crystallize and deposit on the surface of pipelines and equipment during the cycling process, forming a scale layer. The scale inhibitor in the circulating water treatment agent can prevent the crystallization of hard water salts and keep them in a dissolved state, thereby reducing pipeline and equipment blockage and decreasing heat exchange efficiency. In addition, cleaning agents can help remove the already formed scale layer.
Sterilization and biological pollution prevention: The circulating water system is prone to contamination by bacteria, algae, and other microorganisms, which can cause biological corrosion and odor problems. The fungicides and inhibitors in circulating water treatment agents can effectively control the growth of microorganisms, prevent the proliferation of bacteria and algae, and maintain the hygiene and stability of the water system.
Adjusting pH value: The pH value of circulating water has a significant impact on preventing corrosion and scaling. The pH regulator in the circulating water treatment agent can be used to regulate the acid-base balance of water, maintain it within an appropriate range, and reduce the risk of metal corrosion and scaling.
Improving thermal conductivity: In cooling water systems, circulating water treatment agents can improve the thermal conductivity of water, improve heat dissipation efficiency, and thereby increase the efficiency and energy conservation of the cooling system.
In summary, circulating water treatment agents have various functions such as corrosion inhibition, scale prevention, sterilization, and pH adjustment to maintain the quality and stability of circulating water, extend the service life of equipment, and improve the efficiency and reliability of the system. The specific selection and use of circulating water treatment agents should be based on the actual water quality situation, system requirements, and operating guidelines.
