Circular water erosion resistant agent is a chemical additive that controls corrosion and prevent stain accumulation in circulating water systems (such as cooling water systems, boiler water systems, etc.). The following is a basic formula for a common circulating water erosion resistant agent:
Phosphate or corrosion agent: such as sodium phosphate, sodium dihydrogen phosphate, EDTA (ethyleine tetable), etc. Phosphate can form a stable complex with metal ions to relieve metal corrosion; the corrosion agent can form a protective film to prevent the metal surface from corrosion.
Correspondences: For example, organic acids such as benzene, benzoic acid, and case acid. The corrosion additive can form a protective film with the metal surface to slow the occurrence of corrosion.
Sulfuric acid or hydrochloric acid: Some circulating water systems may contain alkaline ingredients, and sulfuric acid or hydrochloric acid can be used to regulate the pH value of circulating water, causing it to be in a suitable range to prevent metal corrosion.
Differentians: For example, sodium phosphate, polyacrylamide, etc. Differentians can prevent the sedimentation and scaling in the water, and keep the circulating water system clean.
It should be noted that the specific formula will vary depending on the characteristics, equipment requirements, and environmental environment of cycle water. When using circulating water corrosion resistance agents, according to the manufacturer’s suggestion and instructions, the dose should be reasonably selected and controlled to ensure the normal operation and safety of the system.
