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.

This product is a fully organic scale inhibitor and corrosion inhibitor specifically designed for power plants, composed of a copolymer of multi-functional organic phosphonic acid, phosphonic acid carboxylic acid, and copper corrosion inhibitor. It interacts with divalent metal ions in water, making insoluble substances less likely to settle, keeping crystals in a small particle range and exhibiting lattice distortion effects, thus providing good dispersion performance for calcium carbonate scale; the copper corrosion inhibitor can form a dense protective film on the surface of equipment, alleviating the corrosion rate. This product is specifically used for scale inhibition and corrosion inhibition in the cooling water of condensers in thermal power plants. Its effectiveness is also very significant under high pH values and high concentration ratios.
