The pre film agent for circulating water cleaning in power plants is a chemical agent used to clean and protect the circulating water system. Its main function is to form a protective film in the circulating water system to reduce friction between pipelines and equipment, prevent corrosion, and reduce the formation of sediment. The following are the main functions of pre film agents for circulating water cleaning in power plants:
Cleaning pipelines and equipment: Sediments, dirt, rust, and other substances often adhere to the surface of pipelines and equipment in the circulating water system of power plants, affecting the flow and heat dissipation of water. Circulating water cleaning pre film agent can help dissolve and remove dirt on the surface of pipelines and equipment through the action of cleaning agent, restoring its original cleanliness and thermal conductivity.
Prevention of corrosion: There is a risk of corrosion in the circulating water system, especially when the oxygen content is high or the water quality is unstable. Circulating water cleaning pre film agents usually contain corrosion inhibitors and film forming agents, which can react with metal surfaces to form a protective film, reducing the chances of metal water contact and thus reducing the occurrence of corrosion.
Reduce sediment and scaling: Soluble salts and hardness substances in circulating water can easily deposit and form scaling on the surface of pipelines and equipment, affecting water flow and heat exchange efficiency. The circulating water cleaning pre film agent can suppress the crystallization and deposition of salts, reduce the formation of dirt, and maintain the cleanliness and efficient operation of the system by adding components such as corrosion inhibitors and dispersants.
Improving system efficiency and lifespan: The use of circulating water cleaning pre film agents can improve the thermal conductivity of the circulating water system, reduce energy consumption, and maintain costs. It can protect the surface of pipelines and equipment from corrosion and sediment, improve heat exchange efficiency, and extend the service life of the system.
It should be noted that different models and brands of circulating water cleaning pre film agents have different formulas and usage methods. Before use, carefully read the product instructions and follow the instructions for correct dosing and operation to achieve the best cleaning and protection effect. In addition, comply with relevant environmental and safety requirements, and ensure appropriate ventilation and protective measures during use.
