This product is a fully organic alkaline formulation composed of phosphonic poly maleic anhydride, organic phosphonic acid, and corrosion inhibitors. It is resistant to high temperatures, with a characteristic of not decomposing at 250℃. In circulating water with carbonate hardness of 100 to 600 mg/L (calculated as CaCO3), the corrosion rate of A3 carbon steel is less than -40.10 mm/a, and the fouling thermal resistance value is less than 2.0×10 m2·K/W. This product is widely used in industrial circulating water in fertilizer plants, chemical plants, refineries, steel mills, oxygen generators, central air conditioning systems, and in oilfield water injection for scale inhibition and corrosion prevention. The recommended dosage concentration is 30 to 35 mg/L.
